He's where he was not minutes ago, and Paul is dragging him out of the way again, this time with more blood coming out of his face and an order given to their shadow. Midoriya doesn't question why Paul preserves this corpse's safety. It is natural to avoid known sources of pain. It hurts.

"Stop it. You're hurting yourself. That's Darkblood."

His voice doesn't shake, but it hints at the possibility as he grips Paul's forearms, as if that could forestall future uses of this power. He touches the tips of his gloves under Paul's nose and shows him the dark glitter clinging to his fingertips. It's incongruous; Paul has always been a Paleblood.

Already his mind is cataloging the data observed. How many times has he encountered a new Quirk and studied it in the midst of a fight? Paul bleeds with each use, and there is no way for Midoriya to know the damage inside without proper examination from a medical professional. Paul can choose a point in time and bring someone with him. Paul has preserved both their memories. (Paul's last command to him to think of their starry cave has flown from his head.)

Midoriya knows enough about visions of the future to know this is vastly oversimplifying it, but at the moment he is only interested in the practical application of keeping Paul out of trouble.
