I do not own Gravity Falls or Harry Potter. They belong to their respective owners.

In this story, Mabel is the annoying sibling who loves Dipper & tries to help him but only makes things worse. Bill is like the asshole older brother who loves Dipper but makes his life hard and Dipper can't seem hate him. Meanwhile, Will is like the crybaby younger brother who is always worried about Dipper. Also, Dipper & his family lives in England, Grunkle Stan & Ford still live in Gravity Falls, Oregon, USA but the town is completely normal.

The reason Dipper was recognized 2 years late is because Bill & Will were always there to help him with their powers.

There won't be any BillDip, WillDip or any other ship. It's just a normal crossover with little to no romance.

This is my first book so I will probably suck & English isn't my first language so there will most likely be spelling & grammatical mistakes.
