[While Izuku would have preferred to use clean fabric scraps that he could throw away afterward for this, he's a little reluctant to leave Guren for too long. So...towels it is. He'll just have to clean them thoroughly or find Guren some new ones later.

Izuku wets one of the towels in the bucket and then carefully begins to wipe away all the blood on Guren's still. He's extra gentle around the worst of the wounds, and his eyes begin to sting again when he sees just how bad they actually are. He'd already known, of course, with the amount of blood covering Guren, but now that he has a clear view of the injuries, he can't help but cry a little, tears tracking a line down his cheeks. If Guren had come out of the fight like this, Izuku can't imagine how the others must have fared.]

How...are you still alive like this? I know Mahiru can heal you, but... this one right here... [Izuku's hand hovers over the horrible stab wound.] I-it's right over your heart, and it went through you...! [He can't even say anymore than that, falling silent in his distress.]
