i have to go off about this for a second. so much of their relationship is about eye contact. we can see it from their very first moments together. cas's unnerving constant stare. and dean looking back at him, always trying to understand. each trying to figure out the other. dean's gotten used to cas's gaze. it's as much a part of the conversation as the words they say, sometimes more. so he knows when cas won't meet his eye, it's because cas feels he's letting him down. so he makes him look. he needs him to see. to see his unwavering faith in him. because he knows cas now. they've saved each others lives. he knows despite whatever doubts and conflicts cas feels... cas has been there for him. dean doesn't trust easy. he's used to people leaving him. and when he met cas, everything was screaming at him not to trust this being. and yet... just as cas had said, "you're different"- cas is different for dean too. a small part of him, a part he'd never admit to anyone, marvels at the fact that his mother was right. an angel was watching over him. and now here he is, in the flesh. he pulled him from hell and left a mark on his body and soul. he can feel it when their eyes meet. yes, they're different. they're tied together now and he will never let cas forget. that he has faith in him.
