PETE: What if it’s a different alternate universe thing?
PETE: Like, there’s a universe where you guys are dead, and this one, and she’s glitching between them?
RUTH: Oh, like parallel universes! In one we died, and it’s a branch off this real one.
RICHIE: How do we know we’re not the branch?
PETE: Let’s not worry about that part. It doesn’t matter.
