Cas: Tell me what's wrong.
Cas: ...fine. If nothing's wrong...then you won't mind if I come with you.
He puts Ren down and starts to walk away
Cas: You're going to the training grounds, right? C'mon slowpoke!
He heads towards the training grounds
Cas: Oh yeah? And who's gonna stop me? Maybe I just wanna train!
He grins at Ren, taunting him
Cas: I FUCKING KNEW IT! Why the hell would you go anywhere he tells you!?
Cas: ...Yeah, I don't think so. I'd like to see what that dumbass wants from you...so I'm gonna go...talk with him.
He starts walking quickly over to the field
