[Crowley glances Castiel's way, realises that once again, he didn't get that subtle hint and sighs. He tucks his wings up and they vanish as if they were never there]

I'll have to run a shower later. Get some bird shampoo.

[He knows, Dear angel, he knows. And it's magic, awesome magic]

For the feathers? It gets them clean without damaging them like regular shampoo does. [Pause] And because I'm worth it.

[Another pause] ...That pop culture reference went right over your head, didn't it?

[Crowley chuckles, patting Cas' shoulder as he walks over to lounge on the sofa]

I'm sure we can get you flashcards or something.

[He'll be nice and make space for him. Probably use Cas as a foot rest the second he sits down, but still]

Oh? You're going to become all wise and knowing in pop culture, are you?

[Oh good, because your lap is going to be used as a footrest anyway. Angels are comfy, it's a lesser-known fact]

Well, I would miss having less to tease you about, so it's probably for the best.
