[Izuku has some idea of what to expect, having talked to Winry and tried to look into prosthetics. Getting information from her about automail and the surgery involved. He's no medical expert, and he was still new and figuring out his abilities here to be able to help with healing. But he is there at his friend's side through the surgery, and to assist him home afterwards, once Bakugo can head back and rest there.

And, well, if anyone knows Bakugo well enough to know he's psyching himself up, that he is trying to get through this in his own way, it's Izuku. Even if he might be a little bemused at the other claiming to have been through worse. He doesn't want to think on that moment when he apparently wondered if the other was actually dead. So he tries to focus on now, as he removes his boots and follows the other inside.]

I didn't say you couldn't handle this. Winry said to rest, so I'm not sure if you wanted to sit or lie down or something? Do you need anything, Kacchan?
