this really reads like a scene from the future to me - like a year from now, after stiles and derek have finally stopped hating each other on principle and started reluctantly working together.
it has all the elements of a friendship (albeit a totally snarky and bicker-y one): the “hey,” the lack of personal space, the way stiles shares his accomplishment with derek as if he’s hoping for a “congrats.”
and don’t even get me started on how derek grips stiles’s shoulders right before he runs into the rave. it’s a “thanks” and a “stay here” all at the same time, and it speaks volumes for the future of this relationship. who else has derek touched so casually? scott and isaac, off the top of my head. both people he considers (or at least wants to consider) his pack.
so yeah, this scene makes me super hopeful.
