Crack! GF AU where Bill is like Varrick and Dipper is like Zhu Li (from the Legend of Korra).
Now I can see this happening in two ways…
1. Dipper makes a deal with Bill and his payment was to become his permanent assistant.
2. Dipper is fascinated with Bill because of his clashing characteristics of ridiculous behaviour but genius mind, so he snags a job as his personal assistant. Of course, he learns the hard way that Mr. Cipher’s antics can’t be decoded into comprehensible things and that he’s actually quite the pain in the ass to deal with.
y’know, whichever floats your boat the most, lol.
AND YOU KNOW WHAT THE BEST PART OF THIS AU IS?
