!THIS IS NOT CANON IN HIS ACTUAL LORE. THIS IS A ALTERNATE UNIVERSE!

Lore if y'all want to read:
Theo, not happy with his life, but can't die due to Thelma constantly watching over him (And has way more iller intentions than in the canon lore) Uses her powers against her so he can go to different universes and kill himself (Or his version of himself) so he can perish once he killed every other version of himself. The last one happens to be his younger self, who is already really depressed from losing all of his family (In that universe, Thelma died of cancer before her head could get chopped off, therefore never becoming a demon to watch over him, and his uncles that were giving him shelter died in a plane crash) Theo, who went through with a very similar thing, struggles to kill him. (And because, y'know, cause he's a kid) Anddd yeah. His younger self, depressed, but not depressed enough to die, ran away once he found out what theo's intentions were (Miiiiiight make it a side story, but then again, I gotta get the actual canon story going lol)
