Cas walks over to the field and realizes Baku isn't there. His eye's widen
Cas: Shit!
He sprints back to the hall
Cas crosses his arms
Cas: So-what's your problem with Ren?
Cas: ...
His eyes widen and he looks at Ren
Cas: ...Ren...
He looks completely heartbroken
He grabs Baku by the back of his shirt collar and pulls him away from Ren. He slams Baku against the wall
Cas: Fuck off.
