Fandom PSLs

I know this is super random, but I've been re-reading Pet Sematary, and want to write Ellie Creed as a 22-ish year old. If you have ideas for the only one left alive in her immediate family that's cursed with a bit of a psychic ability, toss it at me.

I could also write with a Gage that grew up, instead of being killed after being brought back. He could be a bit slow mentally. He would likely be a killer. It could go super dark.

Other Stephen King characters are always welcome, too!
