Stiles and Lydia never should have become friends, for Derek’s sake.

kalpurna: is it weird that I want an original character to call Stiles a cock tease and Stiles is like WHAT and Derek is like what. drunktuesdays: lol that's so specific! why? kalpurna: BECAUSE YOU MADE A TUMBLR POST THAT USED THAT PHRASE AND EVERYTHING IS ABOUT TEEN WOLF + PEOPLE SHOULD TRY TO GET ON STILES'S DICK AND DEREK SHOULD NOT BE ABLE TO HANDLE IT???? MAYBE I JUST LIKE TO THINK ABOUT STILES TEASING COCKS???????????????? For Kalpurna, from whom I stole all the best lines.

It looks like a seizure, Stiles falling down and twitching and writhing on the floor. His limbs are shaking, his body trembling, but afterwards Stiles always tells him it isn't a seizure. Derek isn't so sure. If it's not a seizure, what could it be?
