Melissa McCall (née Melissa Delgado) is the mother of Scott McCall and former wife of Special Agent Rafael McCall of the Federal Bureau of Investigations. She was first introduced in Wolf Moon as a nurse at Beacon Hills Memorial Hospital who was a hard-working single mother to Scott. She remained in the dark about the fact that her son Scott had been transformed into a Werewolf for most of the first and second seasons, instead believing that Scott was simply experiencing academic and behavioral issues that were causing him to skip school, get poor grades, and get into trouble with his teachers.
However, in Season 2's Fury, she finally learned the truth of Scott's supernatural identity when Matt Daehler, the master to the Kanima, Jackson Whittemore, took her and Sheriff Stilinski hostage, forcing Scott to transform in front of his mother to fight the Kanima in order to save them. Afterward, Melissa was horrified and confused to the point where she didn't speak or look at Scott for nearly a week until she was visited by Gerard Argent, who had taken the master position over the Kanima after killing Matt, and who had Jackson choke Melissa with his tail to blackmail Scott into giving him Derek Hale.
Though Melissa continued to be scared of Scott and initially insisted that Scott simply give Gerard what he wanted, she eventually began to understand just how much her son was needed to protect the town and accepted Scott for who he was before insisting that he take Gerard down, giving him the confidence he needed to successfully enact his plan.
Beginning in Season 3A, Melissa began to fully immerse herself in her son's supernatural world, acting as an ally to what eventually became the McCall Pack and essentially becoming the pack's second healer by using her extensive nursing and medical knowledge to help the veterinarian and Druid Emissary Alan Deaton in taking care of their injured and sick members whenever necessary.
Unfortunately for Melissa, this eventually made her a target to the two villains of the first half of the season, Deucalion and Jennifer Blake, the former of whom intended to use her to manipulate Scott into joining his Alpha Pack, while the latter intended to sacrifice Melissa in her Guardian trio (along with Sheriff Stilinski and Chris Argent) in order to give her the power she needed to kill Deucalion once and for all. Luckily for her, Scott, Stiles Stilinski, and Allison Argent, with help from Derek Hale, Lydia Martin, Isaac Lahey, and Alan Deaton,prevailed and saved the parents from becoming human sacrifices.
Afterward, Melissa continued to assist the pack as an ally by helping them investigate and deal with the various supernatural threats in Beacon Hills, such as the Nogitsune possessing Stiles and the Oni pursuing him, the Deadpool hit-list of supernatural creatures, the Dread Doctors and the Chimeras they created, and the Beast of Gevaudan. She also helped her son with more personal issues such as the return of his father and her ex-husband, Rafael McCall, to their family, and the death of Scott's first love Allison Argent, while also dealing with her own issues such as working double shifts at the hospital to keep up with the bills and her house falling apart due to the numerous supernatural battles occurring there.
In Season 6, Melissa took an even more active role in assisting the McCall Pack by accompanying Chris Argent on his hunts, learning a number of skills including how to use the Nine Sacred Herbs as an antidote to the nine supernatural venoms to heal Chris of the wounds he sustained in battle against the Ghost Riders. During this time, she and Chris began developing feelings for each other, which culminated in a kiss in the Phantom Train Station after the two were captured and erased from reality by the Wild Hunt.
Their partnership continued through the last half of the season, where Melissa did everything she could to help, and at times even protect, her pack's members when Chris' father Gerard Argent and his protégée Tamora Monroe began taking advantage of the Anuk-ite's fear-inducement power and using it to turn the human community of Beacon Hills against the supernatural in hopes of committing a genocide. Once they were defeated, Melissa was seen in a committed relationship with Chris in their hometown.
Very little has been revealed about Melissa's life prior to her introduction in the series. What is known is that she was born Melissa Delgado, and that she eventually married Rafael McCall and took his last name. ("Galvanize") While they were together, Melissa enrolled in nursing school, where she eventually graduated and successfully obtained her nursing license. Afterward, Rafael bought her a new watch to congratulate her, which Melissa would later claim was the only thing in their marriage that actually worked. ("Alpha Pact")
In 1995, the two had a son, Scott, who would eventually develop a severe case of asthma. Rafael's alcoholism reached its peak during this time, and Melissa was witness to many bizarre things that he did while drunk, such as returning home from a night of drinking, sleepwalking into the closet, and urinating in the hamper because he believed it was the bathroom until Melissa snapped him out of it. ("Riddled")
When Scott was only a few years old, Rafael was drunk one night and got into an argument with Melissa in the hallway. Scott came out of his room to see what was going on, and Rafael grabbed him by the arm to direct him back to his room, only for Scott to try to pull out of his grip. Rafael yanked his arm back while Scott struggled out of his hold, which ultimately led to Rafael accidentally pushing his young son down the stairs, where he landed at the bottom and hit his head so hard that it left a dent in the wood paneling. Scott lost consciousness for a minute or so, and when he woke up, he didn't remember anything, but Melissa was so furious at the harm Rafael had caused to their child that she immediately kicked him out of the house. ("Insatiable")
Embarrassed and ashamed by his actions, Rafael took Melissa's order to mean that she didn't want him in their lives anymore (when, in reality, Melissa simply was kicking a drunk man out of her house rather than kicking the father of her child out of their lives), and so he immediately stopped drinking cold turkey and moved out. Though Scott has stated that he did live with his father for a brief time after the divorce ("Pack Mentality"), this arrangement didn't last for very long, and Rafael eventually moved to San Francisco, leaving Scott to live with Melissa once again.
After Rafael left Beacon Hills, he seemingly cut off all contact with Scott and Melissa, and Melissa would later say that the two of them were better off without Rafael in their lives, indicating that their divorce was not amicable. ("The Tell") From then on, Melissa raised Scott as a single mother, working the night shift (and often working double shifts for extra money) so that she could see Scott off to school in the morning and after school. Despite being divorced from Rafael, she would later explain to Scott that she kept her ex-husband's last name because it was Scott's name as well and wanted to have that in common with him. ("Galvanize")
Throughout Teen Wolf
In Wolf Moon, Melissa began to suspect that something was going on with her son Scott, though she had no idea that the truth of the matter was that Scott had been bitten by the Alpha and turned into a Beta werewolf. Melissa's first clue was that Scott was going out on Friday night. She asked him if he was attending a party or a date, which caused Scott to admit it was both, and that he was going to Lydia Martin's post-lacrosse scrimmage party with the new girl at school, Allison Argent. Melissa handed him the keys to their car and asked him if they needed to have a talk, which caught Scott off-guard due to the fact that he assumed she meant the "sex talk." However, when Melissa realized what he had assumed, she became flustered and retorted that she meant the talk about filling up the car's tank with gas before taking the keys back, though she hesitantly gave them back moments later.
In Second Chance at First Line, Melissa was happy to hear that Scott's lacrosse skills had quickly improved to the point that he made first line on the lacrosse team. When she informed him that she intended take a day off at work in order to go to his first game, Scott, who still had no control over his newly-attained lycanthropy and was trying to figure out a way to get out of playing on Derek Hale's orders (lest he lose control and transform on the field and expose his supernatural identity), was obviously worried about this news.
Fortunately for him, Melissa assumed that he was worried about their financial livelihood and assured him that missing one shift wouldn't break them. However, when Melissa looked at Scott more closely, she noticed something different about his eyes and how tired he looked and nervously laughed as she asked him if he was on drugs. Not understanding the question due to his distraction, Scott asked her if she meant right that moment or in general, but when Melissa began to get suspicious, he turned the question back onto her, causing her to lose her patience and leave for work.
The next day, Melissa was seen arriving at the lacrosse field in time for their first game and cheered him on from the stands as he managed to survive almost the entire game without involuntarily shifting into his Werewolf form.
In Pack Mentality, Melissa was working at Beacon Hills Memorial Hospital when Scott showed up unexpectedly to bring her take-out food, as he knew she was working a double and likely wouldn't have time to go get dinner. However, when she correctly guessed that Scott was also trying to sweet-talk her into letting him borrow her car, Melissa insisted that she needed it before gratefully taking the food he brought. She later entered the room of Garrison Meyers, the bus driver who was attacked in a school bus the previous evening, only to find him screaming as Scott stood next to his bed, as Scott was afraid that he had unknowingly mauled Garrison while sleepwalking.
That night, Melissa was just about to turn in for the evening when she went into Scott's bedroom to check on him, and when she found it empty, she became concerned. However, this concern turned to fear when Melissa saw someone trying to break in through the bedroom window. She picked up a nearby baseball bat and nearly attacked the intruder before realizing that it was just Stiles, who, having been almost hit with a bat twice in the past week by the McCall Family, exasperatedly asked her if she and Scott even played baseball. Moments later, Scott finally returned home, and Melissa incredulously asked them if either of them cared about the newly-imposed curfew by the Sheriff's department. When both boys answered that they didn't care, Melissa sighed and reluctantly went to bed, stating that she had done the bare minimum of parenting for the day and needed some well-deserved rest.
In The Tell, Melissa prepared to attend the parent-teacher conference night at Scott's school, as all parents were required to attend; additionally, every student with a C average or lower was required to attend the conference with their parents as well. She arrived on time for her first meeting with Scott's chemistry teacher, Adrian Harris; however, Scott, who had skipped school with his girlfriend Allison Argent to celebrate her birthday, lost track of time and forgot to show up. Melissa called Scott several times and left voicemails demanding that he get to the school as soon as possible, but Scott had turned off his phone to enjoy his time with Allison.
Finally deciding to just get the conference underway, Melissa and Harris began discussing Scott's performance this semester. Harris started by pointing out that Scott was frequently absent from school, and when he was present for class, he seemed preoccupied and distracted. He went on to imply that Scott's behavior was a result of a lack of a father figure in his life. When Melissa insisted that she and Scott were both much better off without Scott's father Rafael McCall in the picture, Harris asked if there was anyone else who could fill this role, and if Scott agreed that he was better off without his father, offending Melissa deeply due to the lengths she went to support herself and Scott as a single mother.
After the conference, Melissa was walking out of the school when she overheard Chris Argent leaving his daughter Allison a voicemail demanding her to return his call so he can better determine her punishment for skipping school. She approached Argent and his wife Victoria and asked if they were Allison's parents, as she believed that Allison was with her mysteriously-missing son Scott. Upon learning who she was, Chris and Victoria began to imply that it was her troublemaker son who was encouraging Allison's disobedience, as she never behaved this way before they moved to Beacon Hills and they believed he was a bad influence on her. Offended once again, Melissa reiterated his point regarding Scott's behavior and suggested that it could be Allison who was the bad influence on her son.
Just then, Allison and Scott arrived in the parking lot in Allison's car, where all three parents wasted no time scolding them for their truancy and assuring them that they would be punished for it. Before they could all leave, a ferocious animal was heard rushing around the parking lot; Argent, as a Werewolf Hunter, believed it to be supernatural in nature and began hunting it down with Sheriff Stilinski, who believed it to just be a wild animal. Melissa then watched in horror as Argent shot the creature (a mundane mountain lion) with the Desert Eagle handgun he was carrying.
In Lunatic after learning that Allison had broken up with Scott after the incident at the high school (in which Scott, Stiles, Allison, Jackson, and Lydia were trapped in the school with what they believed was a serial killer but who was really the Alpha Werewolf), Melissa checked on her son, who was hiding in his bed, covering his head with the comforter to block out his alarm clock.
Turning the alarm off, Melissa gently asked Scott if he was ready to go back to school, to which Scott glumly replied "No." When she went on to ask him if he wanted to stay home from school another day, Scott repeated his answer, "No." Melissa, trying to get him to cheer up, jokingly asked him if he'd like a brand new car, and when he simply glared at her in frustration, she retorted that she would like one as well before trying to get him to talk about his feelings regarding the break-up. Unfortunately, Scott was not interested in talking, and when Melissa reminded him that she had been through some pretty bad break-ups as well (implying that her divorce with his father Rafael McCall was one of them), he rudely retorted that he didn't care about her past romances, he was only concerned with winning Allison back.
That night, Melissa was preparing to go work a night shift as a nurse at the Beacon Hills Memorial Hospital when she was suddenly shocked to find Stiles in the house. Startled, Melissa stated that she hadn't heard Stiles ring the doorbell, causing Stiles to calmly reply that he made a key to their front door, which exasperated (but did not surprise) her. Stiles, secretly worried about Scott and how he would handle his second full moon as a Werewolf, dropped a duffle bag full of chains onto the wood floor, which made a loud metallic clanking noise that immediately made Melissa suspicious, but when she gave him a questioning look, Stiles simply stated that it was for a school project.
Melissa, also worried about Scott as a result of his unusual behavior lately, asked Stiles if Scott was doing okay, remarking that he wouldn't open up to her about anything in his life in recent weeks. Stiles, desperate to keep Scott's secret from her for the time being, told her that he was having a rough week. Melissa sighed and got ready to leave for work, making a joking comment about how it was a full moon, startling Stiles, who questioned her on it, causing her to explain that full moons were notoriously chaotic in hospitals and that it was this phenomenon that led to the use of the word "lunatic," a comment whose relevance to the night's events did not go unnoticed by Stiles.
In Wolf's Bane, Jackson Whittemore learned from Dr. Fenris at the Beacon Hills Memorial Hospital that the hallucinations he had been having were due in part to aconite poisoning from when Derek Hale accidentally pierced the back of his neck with his poison-coated claws. Certain that this had something to do with his investigation into Scott and how he gained his superhuman athletic abilities, passed Melissa at the nurse's station and asked her if he could borrow her computer for a brief moment.
Melissa, taking note of Jackson's cocky demeanor, sarcastically retorted that he seemed the type who was not often told "no," but ultimately honored his request after Jackson pretended to be a friend of Scott's. He quickly searched for "aconite" and learned that it was also known as Wolfsbane, leading Jackson to realize that Derek and Scott were Werewolves, though he got rid of all the evidence of his search so that Melissa wouldn't see it once she returned to her post.
In Co-Captain, Scott and Allison were talking in Scott's bedroom at the McCall House when Melissa came into the room to ask if they liked how she was dressed, revealing that she had a date with an "attractive drug representative" whom she met at work. The two assured her that she looked great, but her date arrived before she was truly ready to leave, causing Melissa to request that Scott go and talk to him while she finished up. Much to Scott's horror, he sensed Peter Hale, the Alpha Werewolf who bit and turned him and who was trying to get Scott to join his pack, was the drug representative in question.
Peter smugly stated that Scott would be more willing to join him if his mother was a Werewolf as well, implying that he planned to turn her that evening in order to force Scott's compliance. Melissa was horrified when she saw Scott slam the door in Peter's face, not understanding why he was behaving that way toward a stranger. Melissa then went on to get into Peter's car so they could drive to the restaurant. After some small talk, Melissa, confused, pointed out that they had missed their turn, giving Peter an excuse to pull over under the guise of pulling up a map on his phone to get directions. While they were stopped, Peter complimented Melissa on her perfect skin, which he described as "flawless," a trait he noticed due to his recent healing of his own full-body burns from the Hale House Fire. When he brushed her cheek with his hand, Melissa nervously dropped her phone, distracting her and giving him the chance to extend his fangs in preparation to give her the Bite.
Unfortunately for him (and fortunately for Melissa), his plan was ruined when they were suddenly rear-ended by another vehicle. Melissa was absolutely appalled when she saw that the cause of their fender-bender was Stiles Stilinski, who had purposely hit Peter's car with his Jeep to ensure that Melissa stayed human. She exasperatedly began questioning Stiles on why he did this while Peter quietly commended Scott on his resourcefulness, though he assured him that he could not protect everyone he loved from Peter's influence forever. This seemed to bring an end to the potential date between Melissa and Peter, as Peter had lost his opportunity to make a power move against Scott.
In Formality, Scott and Stiles were walking to the McCall House after school when Scott overheard Melissa sitting in her car in front of their home, leaving Peter a voicemail. She first began to anxiously ramble, making a joke about how it was Melissa McCall, making a (mc)-call. However, once the voicemail ended, Melissa began to cry, believing that it was something she did that caused him to lose interest. Scott heard his mother cry and only began to feel more guilty about the secrets he was keeping from her and his role in her losing someone in whom she had interest, even if Peter's intentions were not pure.
That night, Melissa helped Scott prepare for the Winter Formal as he tried on a suit he bought from the thrift store. When she noticed that his pants had a large split on the backside, she instructed him to take them off and began quickly stitching the hole closed so he could wear the suit to the dance, even despite the fact that he was technically not allowed to attend due to his poor grades (another side-effect of Scott's recent transformation into a Werewolf). While she worked, she and Scott began to talk about the dance, as Melissa needed the car and was curious if his date would be coming to pick him up. Scott sheepishly informed her that he was going "stag" to the dance because there was no other girl who meant anything to him except for Allison Argent.
Melissa asked him if he was sure about his feelings for her, and he confidently answered that he was in love with her, describing the feeling as being "like someone dug a hole in his chest." Melissa smiled and assured him that the sensation would eventually go away before giving him her advice-- "Listen, dumbass, I'm gonna let you in on a secret that most guys don't even have a clue about, all right? You ready? Women love words. You need to tell her how you feel. Just say it. Say it again. Say it differently. Learn how to say it better. Learn how to sing it. You know, just write it in a poem and a letter attached to flowers, carve it in a tree, in a sidewalk with cement, tattoo it on your arm. [...] Just tell her the truth. Tell her anything and everything you want."
In Code Breaker, shortly after Scott's secret Werewolf nature was exposed to Allison and her father, Argent, Scott hid in the exam room of the Beacon Hills Animal Clinic, where he replayed his memory of talking to Melissa about telling Allison the truth about his feelings for her in his head.
In Omega, Melissa was Lydia Martin's nurse at the hospital following her attack on the lacrosse field during the Winter Formal; though Melissa and the other humans believed her to be the victim of an animal attack, in reality, she had been mauled and bitten by then-Alpha Werewolf Peter Hale. She was amused at the sight of Stiles Stilinski sleeping in the chairs outside of Lydia's room, and when Lydia's father, Mr. Martin, asked if Stiles had been there all night watching over Lydia, Melissa corrected him and stated that he had actually been there all weekend.
Melissa, Stiles, and Mr. Martin all fled into Lydia's room when she began hallucinating while in the shower, causing her to scream at the top of her lungs. However, by the time they got into the room, Lydia had already fled out the open window without any of her clothes, leaving Melissa to turn off the faucet she had left running before she ran away.
In Ice Pick, Melissa was shown to be the nurse for Erica Reyes, a young high school teenager who suffered from a seizure while on the climbing wall during gym class. She seemed to be already acquainted with Erica, as she asked the young girl if she had been taking her medication for her epilepsy, only for Erica to admit that she had not before begging her not to tell her parents. Melissa, trying to make Erica feel more at ease, retorted that she ordinarily would, but the hospital had a team of lawyers that would cut off her legs if she didn't keep her guardians in the loop, jokingly adding that her legs were still pretty hot for an older woman and that she would like to keep them. Once Erica's treatment was complete, Melissa left Erica's room, not knowing that the newly-ascended Alpha Werewolf Derek Hale would then sneak in to recruit Erica to his pack.
After learning of a potential relationship that still could be brewing between Allison and Scott (as she had found a note from Scott that read "Because I love you" while snooping through Allison's room) Victoria Argent decided to confront Scott's mother Melissa in hopes of getting more honest answers than she would get from her own daughter. Victoria showed up at the Beacon Hills Memorial Hospital emergency room with a large, deep cut on her arm, with Melissa unaware that Victoria had purposely cut herself with a kitchen knife to have an excuse to be seen by Melissa at her place of employment.
Victoria feigned embarrassment by claiming to have sustained the cut in an unflattering accident, but Melissa assured her that she had seen much worse in her time at the hospital, leading Victoria to guess that it had something to do with "men and their egos." Victoria then took the opportunity to ask Melissa about Scott, specifically how he was handling the break-up between himself and Allison. Melissa replied that she had assumed that the two were no longer dating, but that she thought Scott was doing all right, though she did concede that Scott didn't seem nearly as heartbroken as she would have expected, given how much Scott loved Allison, confirming Victoria's suspicions that the two were sneaking around behind the Argents' backs.
In Abomination, after learning that Scott would be playing in the upcoming games, Melissa made an effort to attend them to show her support. At the game, she had a brief conversation with a student, Matt Daehler, who was also the team photographer. When he saw Melissa cringe upon seeing one of the team members being tackled by an opposing teammate known as The Abomination, he asked if the injured player was her kid, only for Melissa to state that he was still on the field, though she was currently wishing he had stuck with tennis instead. Melissa then noticed the camera in his hand and asked if he was the yearbook photographer, but he cryptically replied that he just took photos of whatever caught his eye; unbeknownst to Melissa, when Matt began scrolling through the viewfinder, it was revealed that his camera was full of pictures of Allison Argent.
Later on in the game, Scott got tackled by The Abomination and broke his leg on the field, causing Melissa, Allison, and her grandfather Gerard Argent, among many others, to run down to the field to check on him. Scott then quickly played the injury off as just a mild sprain due to his Werewolf accelerated healing mending the broken tibia already, but both Melissa and Coach were shocked, as they thought they heard a bone break from the stands.
In Frenemy, Melissa was at work at the hospital when she saw her son Scott in the hallway, as he had been checking up on his friend Danny Mahealani after he was poisoned at the Jungle club. She stopped him to talk to him about his grades, as she was concerned that if they didn't improve soon, he was going to be held back a grade and wouldn't be able to graduate with his friends. This seemed to shock Scott, which was the reaction Melissa was looking for; she reiterated that he could not fail this school year, and Scott promised her that he would get his act together and get his grades up.
In Restraint, Melissa was called has down to the Beacon County Sheriff's Station after Scott and Stiles were accused of kidnapping Jackson. She stood by in the interrogation room, listening as the restraining order was read against them by Sheriff Stilinski. She was beside herself with what to do about all the changes Scott has been going through lately, which led her to list all his bizarre behavior as of recently to Scott in the hallway of the station before she proceeded to ground him.
When Scott asked about the stipulations, Melissa, who had clearly not grounded Scott very often, first stated that she was going to take away his TV, but when he admitted it was already broken, she decided to take away his computer. Scott sheepishly reminded his mother that he needed his computer for school, so Melissa struggled to find another form of punishment until she saw Stiles approaching them in the hall and decided to forbid him from seeing Stiles for the duration of his punishment. Stiles was clearly hurt by this decision and questioned her on it, leading Melissa to shout, "NO STILES!", scaring him enough to cause him to scamper away.
Melissa then demanded that Scott hand over their car keys, implying that he was also forbidden from driving her car, and Scott could tell just how stressed she was when she fumbled around in trying to find the right key so they could leave. Scott took her hands in his own to try to calm her down, feeling guilty for making her feel so terrible, and Melissa wondered aloud what was going on with him, skeptical that this could only be about Allison and their breakup.
Scott sighed, nearly ready to just tell her the truth, and asked her if she really wanted to know, which Melissa did, but when she guessed that it had something to do with Scott's father Agent McCall, Stiles, who was standing behind Melissa, nodding his head "yes" vigorously to point out to Scott that he had just been handed a perfect excuse. Scott hesitantly stated that it was, and Melissa seemed to feel sympathy for Scott and gently stated that they would talk about it at home.
The next day, while Scott was at school, Melissa went into his room to get his laundry and was seriously tempted to snoop around his room to see if he was telling the truth about his dad being the reason behind his strange behavior. She waffled back and forth about it, briefly deciding to just leave the room before the temptation became too great and she convinced herself she was simply going in there to straighten things up a bit. After a few moments of digging around the room, Melissa failed to find anything that seemed to explain Scott's personality changes and sighed before berating herself for violating his privacy. When she began setting everything to rights to make it look like she hadn't been in there, she discovered a large box of condoms in his desk drawer and was concerned when she only found one left inside of it.
Confused and not sure where to turn, Melissa went to the high school, where she went straight to the administration office and approached Victoria Argent, who assumed that Melissa needed to pick up Scott for one reason or another. When Victoria offered to make an announcement to have Scott brought to the office, Melissa admitted that she was actually there to talk to her, which surprised her. Melissa seemed to have told her the story of what she found between scenes, and when Victoria tersely remarked that she was under the impression that their children were no longer dating, Melissa insisted that she thought the same, but that the evidence seemed to state that they were doing a lot more than that.
Victoria was clearly disgusted by this news and asked Melissa if it was possible that Scott was fooling around with "some other impressionable young girl with severely low standards," but Melissa assured her that she knew her son, and that Allison was the only person Scott ever felt strongly enough with whom to go that far, adding that she just wanted to make sure Scott and Allison were being safe, which secretly enraged Victoria, though she did curtly state that she couldn't agree more.
That night, Melissa went to the hospital for her shift and helped Jessica Bartlett, the woman whose husband Sean Long was murdered by the Kanima, deliver her baby. A short time later, Jessica, clearly terrified, begged Melissa by saying, "Please, you have to tell 'em...", but Melissa, assuming that she was just a scared new mother, assured her that the baby was fine. Jessica insisted that it wasn't about the baby, and when Melissa, confused, encouraged her to continue, Jessica rambled that "he" killed Sean, leading Melissa to gently remind her that the police already know. Jessica, frustrated, stated that they didn't know everything, and that they didn't see it, before adding that "it" wasn't human. Melissa, assuming she was just exhausted and traumatized, just humored the young woman, but it was clear that Jessica was still frightened.
In Fury, Scott, Stiles, and Stilinski were at the Beacon County Sheriff's Station, where they were trying to find evidence that Matt Daehler was the Kanima Master. After a few minutes of looking through the hospital surveillance footage, they came upon a young man whom Stiles was certain was Matt in the hallway around the time that Jessica Bartlett was murdered, who was talking to Melissa. They then decided to call her to see if they could confirm Matt's presence at the hospital at the time.
When Scott explained the situation, Melissa reminded him of how many people she saw and spoke every day at work, but when Scott texted her a picture of Matt to jog her memory, Melissa admitted that she did see him that night, and that she had admonished him for tracking mud through the hallway. However, when Melissa asked him what this was all about, Scott quickly said goodbye and hung up on her so the three of them could review their evidence, leading them to realize they could place Matt at the scene of four of the murders. Stilinski decided this was enough for a warrant and asked Scott to call Melissa back and ask her if she could come to the station to make a statement, since an official ID could allow him to get a search warrant.
However, Matt, somehow realizing that the three were onto him, showed up at the station with his Kanima, Jackson Whittemore, which he used to scare them into destroying and deleting all of the evidence they had of him killing everyone he had targeted the last few months. When a knock was heard at the door, Matt smugly remarked that Melissa must be there, and Scott, not wanting his mother to be harmed because of the supernatural, insisted that all he had to do was tell her to leave and that they didn't find anything in an attempt to get her out of it.
Unfortunately, Matt demanded that Scott answer the door, threatening to shoot Stiles and Melissa if he didn't do as he was told. Scott was relieved when he answered the door and saw Derek Hale standing outside of it, believing that they finally had some legitimate back-up; however, his relief quickly turned to fear when Derek collapsed onto the ground, revealing that Jackson had already paralyzed him with his venom.
After some banter and threats, another knock on the door revealed that Melissa really had arrived to the station, and Matt promised Scott that as long as he did everything he told him to do, he would not only not hurt her, but he wouldn't let Jackson near her, either. Melissa was confused when she was let into the station, but when she saw Matt holding the gun in their direction, Scott pleaded with his mother to do everything he said, assuring her that he promised he wouldn't hurt her. Matt patronizingly stated that Scott was right before shooting Scott in the stomach; though almost everyone else in the station knew Scott would eventually heal from the wound, Melissa, still in the dark about the supernatural, was sure that the gunshot would kill Scott without proper medical treatment.
Matt ordered Scott to stand up before he shot Melissa, and when Melissa insisted he needed to see a doctor, Matt mockingly retorted, "You think so?", making it clear that he thought she was stupid. Scott assured his mother that he was okay, though he was pale and sweaty due to his body's focus on healing his wounds, but Melissa insisted that he wasn't okay and that it was just the adrenaline that was making him feel that way.
She then began pleading with Matt to let her take a look at Scott so she could stop the bleeding, and he scoffed before asking, "They have no idea, do they?" He then cut her off and promised to put the next bullet in Scott's head if she didn't stop talking and ordered Scott to lead him into the next room. Once they were alone, Scott asked him why he was still there, since they already got rid of the evidence and he didn't see why his mother needed to be a part of this, but Matt revealed that what he really wanted was the Bestiary, because he needed answers as to why he was starting to develop reptilian scales on his torso, indicating he was turning into a Kanima himself. He then ordered Melissa to be locked up in a holding cell next to where Stilinski had been handcuffed to the wall.
Right after Matt explained why he had killed all of those people on the 2006 high school swim team, a team of Hunters led by Argent, Allison, and Gerard stormed the building, giving Scott the chance to get Stiles to safety as he and Derek, who had finally gotten the venom out of his system, to start fighting back.
Meanwhile, Melissa was cheering Stilinski on as he tried to wrench the cuff off of the wall, but just as she sighed in relief when he was successful, Matt returned to the room and knocked Stilinski unconscious with his gun before aiming it at Melissa. Melissa begged him to let her see her son, reminding him that he had been shot and that she had heard other gunfire and she needed to make sure he was okay, causing Matt to incredulously ask, "How totally clueless are you people?"
Just then, Scott arrived to scare Matt away, but since his back was to Melissa, she didn't realize that he was in his Werewolf form until she called out to him and asked him if he was okay. When he finally turned around, her relief turned to horror as she gasped and whispered, "No!", deeply hurting Scott, who was momentarily relieved to not have to hide this part of himself from her anymore. When he heard the fighting continuing on, Scott had no choice but to leave to try to end it, somewhat satisfied to know that his mother was at least safe where she was.
In Battlefield, Melissa was seen in flashbacks hiding in her bedroom from her son Scott after finally learning the truth-- that he was a Werewolf. Pressing herself against the closed door in her bedroom, Melissa listened as Scott, on the other side of the door, called out for her. When she didn't answer, he reminded her that they were going to have to talk about this revelation eventually, but her continued silence led Scott to sigh and inform her that he was heading to school before telling her that he loved her.
An unknown amount of time later, Scott returned to his own bedroom after taking a shower to find Gerard Argent sitting in his desk chair and Jackson, in Kanima form, hanging upside from the ceiling with his tail wrapped around the panicked Melissa's throat. Gerard smugly informed them that there had been some interesting developments lately before suggesting they catch each other up to speed.
Melissa watched in horror as Scott flicked out his claws, preparing to defend him and Melissa against Gerard and his pet, but when Gerard reminded him who really had the upper hand in this discussion, he insisted that he let Melissa go, and they could talk about whatever he wanted. Gerard made it clear that he still wanted Derek Hale and his pack, but when Scott pointed out that Gerard had them all in hiding, Gerard remarked that he simply needed the right motivation and reiterated that he now had a "fairly impressive means" by which he could manipulate people and revealed that he was doing all of this to avenge his daughter, Kate Argent.
Once the Kanima finally let Melissa go and Gerard left with him, Scott rushed over to his mother to make sure that she was okay and found that she was just as afraid of him as she was Gerard. Melissa hysterically rambled that she didn't know what was happening, what the Kanima was, or what Scott even was, but she made it a point to insist that Scott just give Gerard whatever he wanted to make this conflict end. Scott, conflicted, argued that it wasn't that easy, but Melissa maintained that he needed to just give him what he wanted, even when Scott admitted that he wasn't sure he could deliver.
Despite the tension between Melissa and Scott, she still took the night off to go to her son's lacrosse game and was in the locker room with the rest of the players when Coach Finstock began his annual recitation of the speech from Independence Day, much to Melissa's confusion. She then went on to sit in the stands with Noah Stilinski and Lydia Martin so they could all three cheer on Scott and Stiles. When Stilinski was suddenly confused by the fact that Stiles was running onto the field, Melissa reminded him that he was on the team and was actually starting as first line, which made Stilinski shout and cheer in excitement.
Meanwhile, unbeknownst to Melissa, Gerard was secretly whispering to Scott so that only he could hear and threatened to kill Melissa first before then changing his suggestions to Stilinski, Lydia, one of his fellow students, and Coach Finstock in turn if Scott didn't hold up his end of the deal and give him Derek and his pack. As the game was underway, Stiles immediately got hit during a play, and Melissa and Lydia assured the cringing Stilinski that Stiles was probably just warming up.
When Scott's ally and new friend Isaac Lahey got hit and paralyzed by Jackson on the field, Melissa, sensing something big was going on, rushed to the sidelines to ask Scott if this was more than just a lacrosse game. Scott insisted that she go home, but Melissa refused, stating that not only was she not going anywhere, but that she took back everything she said earlier-- if there was something Scott could do to help, then she wanted Scott to do it. Scott, relieved that his mother was finally coming around, assured him that he would do whatever it took to stop Gerard and the Kanima's reign of terror.
Once the game ended and Scott had still not handed over Derek and the others, Gerard followed through on his threat by having Jackson kill himself with his own claws on the lacrosse field. Melissa, as the nearest medical professional, immediately began performing CPR on him, but it seemed that he had already died, and Melissa ordered a bystander to call for the medics.
In Master Plan, the paramedics had just put Jackson's body on a stretcher and were preparing to leave the high school in order to take it to the morgue in Beacon Hills Memorial Hospital when one of the medics thanked Melissa for her assistance before assuring her that they could handle it on their own from now on. However, Melissa, too intrigued by this new supernatural world that has been revealed to her, wasn't willing to just let it end there, so she made an excuse to ride in the ambulance with them since she was just going to have to give the police a statement anyway. The medic was clearly not partial to this plan, but Melissa climbed into the back of the ambulance and closed the doors before she could argue any further.
Meanwhile, Melissa's son Scott was still at the high school with his friend Isaac Lahey, where the two were trying to get clothing of Stiles, who was missing, in hopes of using the scent to help them track him down. However, before they could do so, they were approached by Derek and the recently-resurrected Peter Hale.
When Scott, shocked, demanded to know what was going on, Derek pointed out that he thought the same thing when he overheard Scott working with Gerard several days earlier, leading an indignant Scott to argue that he didn't have a choice, because Gerard threatened to kill Melissa. When Scott went on to ask what else he was supposed to have done, Peter piped up that he agreed with him before pointing out how attractive he found Melissa, causing all three boys to shout at him to shut up. They then began to recap Peter's death for Isaac's benefit before discussing how they could stop Gerard and save Jackson.
At the hospital, Melissa had successfully sneaked down into the morgue, where she was staring at Jackson's body laying in a body bag on one of the steel slabs. Clearly nervous and out of her element, Melissa muttered, "Oh, God... are we gonna do this?" under her breath before psyching herself up to reach out and unzip the body bag so she could examine Jackson's body. However, when she finally did it, she was shocked at what she found inside-- Jackson completely encased in a gelatinous cocoon made out of his Kanima Venom, which was leaking out of his claws and onto the floor below. Grimacing, Melissa grabbed a nearby pen and used it to pick up a sample of the venom.
She then went on to call Scott, who was still with Derek, Isaac, and Peter, this time at the Hale House ruins to consult Peter's hidden laptop containing the Hale Family Bestiary. Scott initially told her that he couldn't really talk at the moment, more concerned with the task at hand, but Melissa assured him that she was so freaked out she could barely talk, either before insisting that he needed to get to the morgue so he could see it for himself.
Scott and Isaac arrived at the morgue a little while later, where they were both equally shocked at the sight of Jackson in his jello-like cocoon. Scott immediately asked what was happening to him, but Melissa, new to this world, exasperatedly retorted that she thought he was going to tell her before asking if it was bad. Isaac grimly piped up that he didn't think it looked good, and, as if on cue, Jackson twitched as though he was sleeping, baring his Kanima fangs. In a hilarious twist, the two Werewolves begged the sole human Melissa to zip up the body bag so he couldn't hurt them, muttering "Zip! Zip! Zip!" as she psyched herself to do so; though Jackson did snap at her fingertips on one occasion, she was able to zip the bag up almost all the way.

Melissa is very brave and courageous woman who has been forced to go up against the supernatural several times,and who is dedicated to helping protect innocents against the supernatural despite the fact that she is human herself. She has even been shown to hold her own in these situations, such as how she was able to defeat Ethan and Aiden when they were attacking Scott by shocking them with a defibrillator. As a nurse, Melissa is also a very intelligent woman who is not easily fazed by stressful situations, a skill she developed from years of working as an emergency room nurse, and who has proven herself to be a quick learner ever since she was exposed to the truth about the supernatural world. She is a very hard-working woman, as evidenced by the fact that she has worked countless double shifts and night shifts in order to support herself and Scott, and she manages to keep the household running despite being overworked and underpaid in her position.
Melissa is a compassionate, empathetic, and caring woman with a desire to help anyone who needs it, qualities she passed down to her son Scott, but she has also demonstrated a feisty, snarky, and tough demeanor as well, proving just how complex of a character she really is. She is also so devoted to her son that she was able to bring him back to life after he was killed by Theo Raeken, though she had help from the supermoon that helped to strengthen his durability and healing abilities enough to return to life, even despite the fact that his guilt slowed his recovery. Despite her instincts to protect her son at all costs, she is mature and understanding enough to accept that his work as the True Alpha to the McCall Pack is what keeps their hometown safe from supernatural threats, which is what allows her to keep motivating him to do what he needs to do in order to protect their innocent fellow citizens from harm and actively assisting him in this mission.
Melissa is a very attractive woman in her early 40s with tanned white skin, warm brown eyes, and long, wavy-curly brown hair. She is often dressed in her hospital scrubs, which she usually chooses in pastel colors such as light blue, green, pink, or purple, and which she occasionally pairs with a white or gray cardigan sweater. Because she spends nearly all of her time working, she is rarely seen in non-work attire, though she did put on a very nice dress for her date with Peter Hale, and she has occasionally been seen in pajamas and a robe, or jeans and a sweater during her rare hours off of work. She keeps her makeup to a minimum, typically only wearing a little blush and mascara, and she has a gold chain necklace with a small pendant that she always wears as well.
- Medical Training: With Melissa being a registered nurse at the hospital, she has acquired a great deal of medical skills and training. The fact that she has been able to perform these kinds of procedures and other treatments such as chelation therapy and injecting cortisone into vocal cords suggests that she may be a nurse practitioner, an advanced-practice nurse who is only a step below that of a general physician, giving them the authority to conduct histories and physicals, perform complicated procedures, and prescribe medications. She often uses her advanced medical and nursing knowledge in conjunction with Alan Deaton's expert veterinary knowledge in order to help treat the various supernatural creatures (and those humans sickened or injured by the supernatural) in Beacon Hills.
- She managed to save Danny's life after he was brought to the ER with tension pneumothorax by using an open-ended syringe to release the air in his pleural cavity, which had created so much pressure that it was smothering him. ("Currents") She identified the symptoms Stiles Stilinski was experiencing during his possession by the Nogitsune were almost exactly the same as the symptoms his mother, Claudia Stilinski, experienced as a result of her fronto-temporal dementia. ("Silverfinger"), ("Riddled") She was shown to be capable of performing an autopsy a skill she has utilized several times; first, when she and Stiles identified the Darach's sacrifice victims had been killed by the three-fold death ("Fireflies"), a second time when she and Alan Deaton examined the body of Satomi Ito's Beta Reed Schall, allowing them to determine that he had died from a weaponized and modified canine distemper virus("Weaponized"), and one last time on the flayed corpse of Aaron after his DNA and appearance were stolen by the Anuk-ite. ("Sundowning") She helped keep her ex-husband Rafael McCall alive after he was seriously wounded by an Oni demon, stabilizing his wounds while the McCall Pack fought them off. ("Silverfinger") Melissa attempted to save Hayden Romero's life using intravenous chelation treatment to filter out the Dread Doctors' Modified Mercury serum after she was given an overdose of the substance, but it was ultimately unsuccessful due to the fact that the mercury had been scientifically modified. ("Status Asthmaticus") After her son Scott McCall was killed by the Chimera Theo Raeken, Melissa managed to resuscitate him with CPR despite him having been without a breath or heartbeat in over fifteen minutes, due in part to the power of the supermoon to trigger his accelerated healing ability. ("Status Asthmaticus") When Lydia Martin was slashed in the throat by Sebastien Valet's claws, Melissa managed to help her get her voice back by injecting cortisone into her vocal cords. ("Apotheosis")
- Botany/Herbalism: Melissa has also recently learned some supernatural methods of healing people, primarily how to use the Nine Sacred Herbs of the ancient Anglo-Saxons to heal someone exposed to supernatural toxins. She used the combination of these herbs (which includes mugwort and honey as a binding agent) to heal Chris Argent of the poisoned whip lashes sustained by the Ghost Riders ("Ghosted"), Peter Hale from the full-body burns he suffered as a result of traveling through the Rift between the real world and the Phantom Train Station ("Heartless"), and Corey Bryant from the wide variety of wounds sustained by Garrett Douglas' torture. ("Riders on the Storm")
- Resourcefulness: Despite Melissa's lack of combat and weaponry training in comparison to her peers (such as the Hunter Chris Argent, the former soldier and current police officer Noah Stilinski, her ex-husband and FBI Special Agent Rafael McCall, the ancient Celestial Kitsune Noshiko Yukimura, etc), she has demonstrated that she is very good at thinking on her feet and improvising when the occasion arises. She was able to separate the merged then-Alpha Werewolves Ethan and Aiden Steiner at the hospital by shocking them with a defibrillator, ("The Overlooked") and has used other objects as makeshift weapons as well, such as baseball bats. She has become quite proficient at using the taser she was given by Argent, preferring it to a lethal weapon such as a true firearm. ("Said the Spider to the Fly")
- Supernatural Knowledge: Throughout the years as an ally to her son's pack of humans and supernatural creatures, Melissa has learned a great deal about the supernatural world and how to survive in it as a human. She has learned how to wield Mountain Ash and has protected her loved ones with it on several occasions, as she has rowan wood (mountain ash trees) in the baseboards of her entire house. ("Silverfinger"), ("The Beast of Beacon Hills") She has an extensive understanding of the healing processes of the supernaturals in her care, allowing her to hypothesize that the Hellhound Jordan Parrish's smoking wounds had something to do with his then-unknown supernatural identity. ("Creatures of the Night") She was knowledgeable about the fact that only a Beta of his own making could steal the True Alpha spark of her son ("Creatures of the Night"), and has used her wisdom regarding the Nine Sacred Herbs to save the lives of several allies.
- Melissa: Melissa is the Greek word for "honey bee," which in turn comes from meli (μέλι), which simply means "honey." In addition to this Greek etymology, it could also refer to the Hittite word melit, which also means "honey." Melissa was also both the name of a nymph in Greek mythology who cared for a young Zeus, as well as the name of the fairy who helps Rogero escape from the witch Alcina in Ludovico Ariosto's poem Orlando Furioso (1516). The name also refers to the plant Melissa officinalis, in the Lamiaceae family, which is known as lemon balm, and is sometimes used in Ireland as a variant of the Gaelic male name Maoilíosa, which means "servant of Jesus," though this is of a different origin and has nothing to do with its Hittite origin. As an English given name, Melissa has been used since the 18th century. Variants of the name in other languages include: Mélissa (French); Melitta (German, Ancient Greek); Melika (Hawaiian); Melisa (Spanish); Melis (Hungarian).
- Delgado: Delgado is a Spanish and Portuguese name that originates from the word delgado, which is a nickname for a thin or slender person. It is derived from the Latin delicatus, meaning "dainty, exquisite," a derivative of deliciae, meaning "delight, joy." It is one of the great names of the Iberian Peninsula in Spain and Portugal, and in one way or another, the name Delgado is found in every place in the world where those respective cultures have been prominent. It is also often a place name, and can sometimes be spelled Delgadillo or Delgardo, and is used to describe something very special and/or beautiful.
- McCall: An Anglicized form of the Irish Gaelic surname Mac Cathmhaoil, meaning "son of Cathmhaol," a personalized name with the elements cath, meaning "battle," and maol, meaning, "chief," i.e. "battle chief." It is also the Anglicized form of Mac Cathal, meaning "son of Cathal." Variant transcriptions of the name include Macall, Maccall, Maccaul, and Mackall.

- It was revealed that Melissa's maiden name is Delgado, suggesting that, like her husband Rafael, she may have Hispanic heritage.
- Melissa quickly embraced the supernatural world after being introduced to it in Season 2's Fury, although she did have a brief period of fear in which she rejected the truth due to being overwhelmed by the revelation that her son Scott and terrified by the threat of Gerard Argent and the Kanima under his control, Jackson Whittemore.
- Due to Melissa, Chris Argent, and Noah Stilinski's positions as guardians to their children, Scott, Allison, and Stiles, and the fact that they assist their children in guarding the innocent townspeople of Beacon Hills, they were targeted by Jennifer Blake as part of the "Guardian" trio in her Darach human sacrifice ritual. Chris, Melissa and Noah's trio relationship is a parallel to that of their children, Allison, Scott and Stiles.
- Based on the medical procedures Melissa has been seen performing throughout the series, it is likely that she is not just a registered nurse (RN), but a certified nurse practitioner (CNP), an advanced practice nurse who is capable of prescribing medications and performing complicated procedures under the supervision of a physician.
