Stiles is worried that he may have frontotemporal dementia when he starts hallucinating Derek. It’s only after he’s on the roof that he realizes this was a trap from the latest Baddie to try and kill him. Thankfully, the real Derek shows up to save the day.
In fact when they finally make it official and start dating stiles thinks to himself "hell yeah I'm the nerd who got the hot guy" which is also the same exact thought that derek has
Stiles: Hey. Hey, Derek.
Derek: ...what?
Stiles: What do you call a lost wolf?
Derek: No.
Stiles: You call it-
Derek: Stop.
Stiles: -a where-wolf!
Derek: Goddamn it.
