[ In a way, this moment feels the same as the one that night when Cas first leaned his head on Dean's lap and wasn't shoved away or berated for it, but welcomed. They've spent so long respecting each other's space while being forced into close quarters that even the idea of pushing for more is terrifyingly strange, a new world, literally. Castiel never would have pushed Dean back home, because there was too much there to risk losing. And it's likely Dean would have pushed back then, rather than accept him as he has here, and it's just... It's a very strange feeling, like coming in from the cold, and the sudden warm has your fingers burning with heat, aching, even as they thaw from frozen.
Dean's silence aches, and his answer is painful, and the "why" that Dean says he's supposed to know splits like a fork in his mind, between this dreamworld being an unreality, or that it's changed Dean in ways that scare Cas as much as it excites him. He looks down at his hands again, at a tomato seedling that's only just sprouted, and already the lowest leaves are yellowing. Gently, he pinches them off. ]
In that case, I wonder... Do you know why you?
[ If he's going to risk nurturing the little seedling of an idea that he might have some kind of significance to Dean, then it's important that Dean knows he's not insignificant to Cas. Maybe it would be easier for Dean, or for both of them, and pointing it out might uproot things before they've started, but he can't let Dean believe that he's anything less than the center of Cas's universe, regardless of what universe they've happened to have found themselves in. ]
