|“||Melissa: "It's not just this, although a restraining order is a new low that I didn't think that you would reach quite this soon. The completely bizarre behavior, the late nights coming home, having to beg Mr. Harris for you to make up that chemistry test you missed..."
Scott: "I missed a chemistry test?"
Melissa: "Really, Scott? Really? I have to ground you. I am grounding you. You are grounded."
Restraint is the seventh episode of Season 2 and the nineteenth episode of the series.
After Jackson escapes from a prisoner transport van that Stiles and Scott are holding him in, his father gets a restraining order against the two of them. Scott's mother searches his room and discovers that Scott has been having sex with Allison and lets her mother know. A fight between Scott and Jackson lands everyone involved in detention. Jackson transforms, injures Matt and Erica, and leaves a warning from his master. Erica has a seizure as a result of the Kanima's venom and Scott and Stiles rush her to Derek. Lydia meets the strange boy she has been seeing around, only for him to reveal himself to be a younger version of Peter Hale. Lydia realizes that the young boy was a part of her imagination and that Peter has been communicating with her via hallucination all along.

- The title refers to the restraining order Jackson Whittemore gets against Scott McCall and Stiles Stilinski after they captured him and locked him up in a prison transport van following Jackson's attack at the Jungle nightclub.
- Information about Jackson's biological parents and their deaths was revealed in this episode by Erica Reyes, whose father was the insurance adjuster in the case. His birth parents were named Gordon and Margaret Miller, and they crashed their car on Route 23 past mile marker 2 off of Old Deacon Road in Beacon Hills on June 14, 1995. Skid patterns indicated that the car swerved before the driver lost control, and they were declared DOA at Beacon Hills Memorial Hospital. Jackson was then delivered by cesarean section despite his mother already being dead, and was presumably adopted some time later.
- It was also speculated that Jackson's parents may have been murdered, which would fit with the Kanima mythology.
- It is revealed that Jackson did not believe that he was the Kanima; instead, he was under the mistaken impression that he was, in fact, transforming into a Werewolf as he expected, but that the process had somehow been slowed down considerably due to his contact with Lydia Martin, whose immunity to the Bite he believed caused the deceleration.
