[maybe that's also why dabi could easily tell the explosive blonde is an idiot and had no intention of going near him to undo his bindings. don't need to be a fucking child psychologist to know when someone's going to blast you for your efforts. shouto can get all friendly with that thing; weird for weird.]

Dick.

[whether that's touya filling in the blank for natsuo's more polite "idea" or simply taunting him for being one is up to his little brother to figure out. the smirk on the villain's face suggests it's at least more a tease than an insult.

he goes quiet when natsuo launches into a detailed diagnosis of his current health. not sure if he's annoyed by it, kind of disgusted, or honestly impressed. guess it's not that hard to rattle off the visual cues, but natsuo obviously knows what he's talking about and it shows in his words.]

Real impressive. My own private physician. How much do I owe ya for all that?

[at least it's nice to know some more of what's obviously wrong with him, and still get some head pats for managing some semblance of a decent diet despite his life on the streets. while he'd like to blame most of this on their mother, both for passing him an ill-suited body for his quirk and for giving birth prematurely, he already said that earlier and natsuo already knows.]

Cute, but ya can't "heal" scars. And why should I bother? I'll just burn myself again after they heal what's left. I got all mom's weak genes. [he almost spits the comment.] At least my flames are stronger than Endeavor's.

[as for infections, touya shrugs callously.]

Who knows. Maybe my body temperature and fire's too hot for somethin to set in. I take care of what I can.

[there's not enough healthy skin left on him to make skin grafts even a remotely feasible idea. dabi looks at natsuo and then lazily tugs the open collar of his shirt to the side.]

Ya wanna give me a check up, Natsuo?
