It should be interesting, since heroes existed in Peter's world for more than those few years, he assumes. Was it because Peter suddenly found out he could become a hero or did something happen to finally get him off his ass and use his powers as a hero? Things Bakugo will find out when they talk about it.

"Tch, most people would only want to know that if they could change it." Being told when you have no way to prevent your own death would be a shitty piece of information to learn. Bakugo's going to figure out that's sort of the way things operate around here, but it won't be for a while. He has to watch what he says around anyone from his world, since he's pretty far in their timeline...

"I didn't ask for details! You could've just said yes or no!" Rather than expounding on it. Sheesh.
