A spinoff of gravity falls. What would have happened if Mabel pushed that button? Would Bill have ever broken through or would the twins never get answers to the mysteries of Gravity Falls? In this spinoff, Mabel pushes the button at Dipper's urging - feeling the same ultimate betrayal that another pair of twins once felt. *Disclaimer - I do not own the rights to the gravity falls franchise or anything along those lines. This is a fanfiction piece based on my love of Gravity Falls and nothing more. I enjoyed playing around with the idea of what if - and this is the result.*
