[For a brief moment, Katsuki sets his jaw and is about to grind out the usual "don't tell me what to do" verbiage he normally would, but he can't deny that he is tired and hasn't slept for...probably a full day now, maybe a little bit more than that. Instead, however, he merely narrows his eyes and scowls a little bit, but doesn't refuse outright. He doesn't want to stop, even if he knows he should, because the fact it got this bad in the first place feels like a failure on his Hero's pride. He should be acting now, not resting. Yet...he remembers what he said to that shitnerd before coming to this place and heaves a grunt and sigh.]

I'll take a break, that good enough for you?

[He's irritable, mostly because of the lack of sleep and the stress, but he's far more dulled than he would be otherwise. Besides that, there's also a kid practically in his lap who needs his attention far more. He's not going to start shouting.]

Aa, in a way. You'll find, here, it's not as uncommon as you might think. My world's full'a people who have quirks. [He enunciates the word, clearly indicating that's the term used for powers and special abilities in his world.] And it's not fire, fire behaves differently than this.

They're explosions.
