Hey, so I was thinking as an alternative to the mind-wipe situation, that Mabel AU could have her in a situation where she had a twin brother (who would’ve been Dipper) that died before they were born, and somehow something supernatural in Gravity Falls makes her start to see the ghost of Dipper-that-would-have-been that’s been with her her whole life without her really realizing it - and suddenly a lot of things start to make sense. And so then I wrote something about it. I’ve never written fan-fiction for anything before, so it’s probably not any good, but anyway, since it was inspired by your idea I figured you had a right to see it. I’m submitting it here because I don’t have a tumblr. Feel free to do with it as you will.
