(This story takes place a little after season 2 episode 11 AKA [SPOILER] when Ford comes out of the portal. If you've seen the episode, you'll know who I'm talking about, if not, don't read on!)
Mabel Pines is still the quirky girl she's always been, but when she bumps into Bill Cipher, things change, but the question is: for the better or for the worst?
Disclaimer: I don't NOT own Gravity Falls or the characters in it. I may add new characters in and stuff but that's about it. I mean it's pretty obvious that I don't own Gravity Falls.
