Stiles picked up Lydia and they raced to save Jackson. Showed up just in time to take out Gerard, temporarily , and Jackson's extra house key he gave to Lydia brings him back to human state. And for future reference, Stiles scream, get out of the car, they run from the Kanima but when Stiles notices Lydia isn’t next to him and is standing in front of Jackson trying to get him to remember , he immediately does what I like to call, pulling a Stiles and goes to rescue her without any regard to his own safety, knowing full well she is in love with Jackson. Scott stops him. Some people might call, pulling a Stiles , a SCENE: I however do not… Turns out there is more.. Jackson “dies” and Lydia cried and , so in love, Stiles goes to comfort her but before he can Jackson wakes up. Yeah this keeps getting so much better (not) Sigh.. Looks like Jackson dying made the Kanima leave but the sad look on Stiles face and a tear is too much for the keeper of Stiles love for Lydia to bare after Lydia runs to Jackson and hugs him.

Scott notices, Stiles is crying..

Stiles: “I scratched my jeep” Stiles makes up an excuse, trying to make everyone else ignore the fact he's upset. He starts to walk away.
