[Welcome to dealing with your amnesiac son, Bellamy. In all seriousness Hiro knows there's still something bizarre here but he doesn't seem to mind. He's willing to put it aside as he focuses on the injury.]

That we can do. Baymax? [Baymax focuses on Bellamy again, hand up as he stares down at Bellamy's injury.] I advise an antibiotic spray in order to prevent infection, followed by wrapping in clean bandages. I will spray your wound now.

[And while Baymax waits for Bellamy to hold out his wounded arm, Hiro's reaching into his utility-belt-pouch to pull out some bandages.] Word of advice? It's easier just to let him do his thing without asking questions. You gonna jump back into the fight as soon as this is wrapped up?
