Dean: What the hell is that?
Doctor: It’s a kitten! Well, not a kitten per say, it’s Castiel’s kitten. I thought he might like something fluffy that he can love.
Dean: Well we’re not keeping it.
Doctor and Castiel: ….
Dean: We’re not! Don’t give me that look.
Castiel: It would be cruel to abandon Dean now, we have already bonded.
Dean: I’m sorry…what?
Martha: The Doctor told him to name it after something important, so he named it after you.
Dean: Well…I guess…maybe…he could stay. But you’re looking after it!
Doctor: Excellent, allons-y Castiel, let’s get him settled.
Castiel: Dean, you are very…sweet.
Dean: Cas! This is hardly the time -
Castiel: I was talking to the cat.
