"So, remember the blonde girl? Yeah, she's the baddy, trying to use magic to become immortal. That blonde guy, that's also her, she used magic to take on his skin. Yeah, not just his appearance, she grows his skin every time she needs to become him. So, the teenage daughter ended up getting cursed by the evil cops who also know magic, so the main characters go back in time to the Tulsa Race Riots in order to grab a magic book. Why they didn't go a day earlier instead of right when all the shit goes down, who knows, that's not how time works here. They end up getting the book, and uncurse the girl, but she's still got a dead arm where the curse demon slashed her in her mind.
The main character still goes to the magic séance that blonde girl wants to do to become immortal, even though everyone told him she needs all his blood to do it, and he needs blood to live. Dunno why he didn't just nope that out and hop off to Canada, considering his aunt is now a superhero because she went traipsing off through time and space, lived a couple hundred years, and has infinite knowledge. She could probably find a way to hide them. But anyway, he martyrs himself, gives her all his blood, and then his fox demon he met in Japan in the war sucks all her powers away through evil tails that come out of all her orifices.
Oh, and when this was going on, Aunt Superhero took teenage daughter through Time and Space, and gave her a terminator robot arm instead of her dead cursed one, so she killed blondie good. Now she's supposedly gonna go off having adventures with her pet shoggoth.
