[Castiel snorts, huffs a bit of laughter, the corners of his mouth twitching upwards.] Are you a cheerleader now, Dean? I don't know if you have the legs for the uniform.

[Castiel doesn't always sass Dean back, but, when he does, he very much enjoys doing so. He watches Dean with obvious fondness, regardless; he meant it when he told Dean he loves him, and he will never stop meaning it.]

There's a first time for everything, isn't there? You taught me that.

[Castiel nods.] Well, that's good, then. As long as the kids are alright.
