[In all honesty, Katsuki normally isn't this antsy, and he's reigned in his desire to simply blast first and ask questions later. He's not supposed to be this high-strung, he's supposed to be better, more composed, more in control...but he's not. Not entirely. And that is a massive concern - if he can't control his reactions to even the slightest stimuli, then he may not be able to control the output of his quirk, his explosions. And where there are people trapped, crying for help...for someone to save them, for a hero.

He can't loose control.]

[He doesn't trust you, but he's got no other choice. Uraraka's not here right now - she's doing her part elsewhere.]
