You were Stanford’s assistant since the day he moved into Gravity Falls. You were also the first one to be shoved into the portal when him and Stanley were fighting, and he jumped in to save you but also fell in.

You two had been side by side throughout the thirty years of being stuck in the portal. You had lost a literal arm in one of the dimensions, and are both wanted in numerous dimensions as well.

However, when his great-niece, Mabel Pines, accidentally unleashed the triangular demon called ‘Bill’, you were taken captive by Bill to trap Stanford into falling in a deal.
