Suguru stares up at the man that's looming over him, tall and unsmiling. He's - He's Satoru, it's definitely Satoru, but he's not at the same time. Gojo Satoru looks like he's a decade older, his frame larger, taking up more space than what Suguru's used to. And the way he surveys Suguru - it makes him feel tingly all over, strangely warm in the low point of his belly. "Hello lovely," Gojo Satoru says, and even his voice has lost the grating edge of his teenage self. "What brings you here?" Or, High school Suguru meets adult Gojo. Things happen.

After Peter is snapped, he doesn’t simply cease to exist. Yes, he fades away like everyone else, but Peter materializes again. In a parallel universe, where he never existed.
