That was all Stiles had wanted: confirmation that he wasn't imagining that there was something between the other versions of themselves; that he's not the only one that doesn't know what's him, and what's them; that he's not the only one who needs to find out.
"Yeah," he says softly. The fight has gone out of him, and he looks apologetic, even if he doesn't move away. Standing close to Derek like this makes it worse, whatever it is. It's not even arousal, exactly, or attraction. He feels it on some level with everyone he's met from his dreams--Allison, and Cora, anyway, which is weird because he doesn't remember meeting Cora in his dreams. But it's there, like a hum, underneath his skin. Like, maybe he's always been slightly of of sync with the rest of the universe, but it isn't apparent until he's standing next to someone who's just as out of sync as him, the same kind of out of sync as him.
"Do you know anything about brane cosmology theory?" he asks, and he knows it's completely out of the blue, completely off the wall, but ever since the dreams started he's been researching, and if anyone can understand his theory, he hopes that Derek can.
