[Katsuki's brows pinch together. Yeah, he probably should at least pace himself, but he's...stubborn. Besides, sticking around here is dangerous no matter what, it's an unknown place and he's, well. He's quirkless and injured. If attacked, he can fight well enough on his own - UA definitely taught basic hand to hand melee and self-defense/offense - but it can only go so far. Not only that--]

And you expect to find one where? How? When? [Katsuki growls, taking a deep breath and then strides forward, despite this young woman's protests. Does he have a heading? Not yet, but he'll figure it out. At least he can track his path...until the paper runs out. After that, he'll think of something else.] Like I said, there's plants here I don't recognize, and I don't know how toxic they could be, or if they even are. But back home, there's plants so poisonous that even being near 'em for a long time can get you sick.

Think I'll take my fucking chances on my own two legs. [He snorts, but then his tone does shift to not be...as nasty. She doesn't mean anything by what she said, Katsuki gets it, but he still can't shake the knock to his pride. He's not weak. He can walk.] ...Pain's not the worst unless I push it. Walking's not gonna kill me.

[Though he will tire easily, even Katsuki can't deny that. His stamina has been reduced to, well...level 1 baby mode, pretty much.]
