Honestly the "soul corpse" being bound to the object and resetting to the position it was before makes sense, since if it wasnt like that, you would wind up somewehere in space each time you rewind, if you think about the rotation of the earth and our movement through space.
Genuine question about the voices: is Joe tone deaf? I get that voices are hard, but Elvis is known for having a deep voice, but Joe doesn’t seem to make an effort to make his deeper. He doesn’t seem to really try changing the pitch at all when he goes for the voices even though that would probably be the first thing you’d try to change, which makes me wonder if he just can’t hear pitch, since it’s actually pretty common for people to just lack that ability (around one in twenty people). Plus, being tone deaf would be a pretty good excuse for chat if Joe doesn’t want to do voices.
