Probably. The whole episode was basically a combination of fanfic plots, man. Stiles and Lydia go to Mexico, Derek is suddenly young enough to date Stiles, Scott risks himself for Lydia, Malia and Kira have a sexy dance that sparks fantasies, Stiles is teaching Malia how to be a human... those are all things I've seen on tumblr, for sure.
Oh, I'm sure it isn't! But you've got to imagine the ridiculous face he's making just there.
