Cas grins
Cas: Tell me or I do it again.
Cas pries his hand away and bites his lip even harder than before
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
