[He doesn't have enough energy to argue back with Katsuki. His ears are starting to ring and he can see the blackspots in his eyes again even while Katsuki is struggling to get his shoulder to stop bleeding. He blinks at Katsuki and tries to focus on his words. Can't pass out...

Izuku reaches up to touch Katsuki's wrist then slides his hand up to his shoulder where the wounds are and messily gets more blood on his hands as he presses Katsuki's hand to it.]

You can't ... stitch me up. Infection... [He winces again and takes in a slow breath.] S-slow down the bleeding. The best you can do is apply pressure. C-carry me to the ... hospital, Kacchan.

[Izuku needs clean bandages and clean stitches. Depending on how must blood was lost he might need a transfusion. But they can't do any of that in the middle of a flower field.]

You're fast, I... trust you.
