Their whole life they had been separated. Their whole life they never knew they existed. Their whole life they had lived without a sibling. Dipper growing up in Gravity Falls, Oregon with so-called 'Stanford Pines' and Mabel in Piedmont, California. It stays that way until the age of 12 where Mabel finds out she has a brother up in Oregon. She will get there no matter the cost or length. Ecstatic and enthused when she finally gets to her destination and when she finally finds her long-lost twin, she quickly tries to bond and be with him. Her brother on the other hand? Not so much. Even though it took some arguments to get it through his head, Dipper had to accept the fact she was staying for the summer. That summer of 2012 is even more crazier than imagined, filled with new creatures and wild adventures. Mabel and Dipper have never been together before...but it doesn't mean they won't be by the end of a couple months.

Mabel has been dying to ask out her crush, Pacifica and after many hours and failed sweaters, she finally found the perfect thing to propose a date with the "Girl of her dreams.".

[COMPLETED] Gravity Falls (semi-original) Triplet!AU, inspired by the fanart and comics created by doublepines Imagine if Tyrone hadn't died at the end of the episode, Double Dipper, how would the twins' lives had changed? After four years of feeling like the runt of the family, Tyrone (aka Ty) Pines finally gets his opportunity to visit the not-so well known town of Gravity Falls, the one topic that his siblings can't seem to stop talking about. While staying in town, Ty writes about his many adventures that include uncovering a dangerous secret, dealing with a love triangle and finding himself mixed up in some good old fashioned sibling drama. Can Ty juggle it all and possibly save the town from its destruction? (. . .um, again.)

Bill has found his way around the Pines family's defenses, again. What's he going to do once he gets into their minds, and finds out Dipper has a crush on him? Furthermore, he tries to deny the obvious fact that he likes Dipper back.

This is a Gravity Falls fanfic. It starts when Dipper and Mabel are 'born'. The truth is Mabel and Dipper aren't twins. They aren't even siblings. Dipper is a demon. However with a little possession and manipulation Bill is able to convince the Pines family that Dipper is Mabel's twin brother. Why? Because Bill just wanted to protect his brother from the war in his dimension. Everything goes great. But what happens when Dipper finds out he isn't as human as he thought? And Bill comes to claim his brother? I do not own Gravity Falls. Alex Hirsch does. I also do not own the art on the cover!
