Two Sides of the Same Coin

What if Mabel Pleasure, the Lone Wolf, wasn't capable of chaining Bill Cipher by herself? What if she needed help? Although she wasn't a fan of the option that was given to her, desperation at times made her do things she didn't expect to.

She knew the price of what she made for the chains, but she didn't expect it to happen when the Wheel was complete, and Bill Cipher was finding his way out.

Now, in front of her, was... Herself? Wait, was that Dipper with Dipper? Why were they dressed differently? What was going on? Is the entire town like this? Wait a minute. . . If there were other versions of them appearing. . .

Where was Bill?

(Two Sides of a Coin is an AU crossover originally mine, with the AUs of Defying Gravity and Reverse Rises. The plot ideas were all made by me using Defying Gravity+headcanons and Reverse Rises+spoilers I got from the author)

(When commenting on this, do not cuss or say anything inappropriate for children. This book is for all community of Gravity Falls, targeted mostly to the community of Gravity Rises and even for the ones that like fantasy and adventure but do not watch the show itself.)
