Cas morphs back into his human form, smirking at Aizawa and stretching
Cas: You got anything harder, teach?
Cas: Hm...this should be good...
He says that sarcastically, taunting Baku
Cas rolls his eyes, slow clapping
Cas: sarcastically woowwww...so impressive...
Cas seems kinda pissed off by this
Cas: Whatever.
He does seem a little less pissed when Ren says he's gonna try, he's curious. He watches, fascinated
Cas: Woah...
He seems genuinely impressed
