Guh, Pyro. It appears he's had his old self scared out of him, or worse. He doesn't even remember.

Now I'm imaging how others would be different in this universe. MC I imagine to have developed an elaborate delusion that he's stuck in a speedrun, constantly pacing because you can't stop moving or you lose time, agonizing about "the strats, I can't remember the strats!" and being even more terrified when someone tells him there's no reset when something goes wrong.
