I really, really do not want to know how Kayden is gonna recover from exerting himself that much when he hasn't recovered. But also. If he could put out that much power (even if it is more than when he first met Jiwoo), wow he's been holding back. Coulda roasted that beast-tamer guy with the ridiculous eyelashes. Instead, bro got off with some amnesia. Sure, killing him would've complicated things, but imo it would've been funnier.
