[All Might reaches for the splint and then realizes he should have been shielding the damage better--sorry Monoma, this isn't a case of bruised and lacerated knuckles. He sets the splint down, reaching out to set his good hand on Monoma's shoulder before forcing a smile. It isn't convincing on his real face, not with his sunken cheeks and hollow eyes or his too-thin lips, and not with the cold sweat he's breaking out in--but he tries anyway.]

It's alright Monoma, my boy. Very poor decision-making on my part but it's nothing to worry about. I want you to watch for Young Midoria and Young Uraraka while I deal with this. Let me know as soon as they come back.

[It wasn't necessary to have Monoma be a look out--he just didn't want the boy in the room and seeing him like this.]
