Miles never really knew Peter Parker. There was the older Peter Parker from another dimension, but he doesn't think that's the same. He lived a different life, so Miles is pretty sure he's not really the same person. Still, he gets where Jessica is coming from. It's weird.

"He at least knows that happened though, right?" Miles asks, and it never really occurred to him until now that maybe Peter Parker doesn't know he's supposed to be dead at all.
