You and Ford were both scientist-partners that were working often on some big projects, and because of some cray-cray ideas that went throu Ford's head that time, you both built a portal, accidently into the NightMare Realm, and then one day getting sucked in after stepping too close. Truns out, Grunkle Stan who is Ford's brother was all these years trying to rescue him, and maybe even you in the process, and it worked! as unbeliveable as it seems after 30 long years, you and Ford were back, and Ford didnt even thanked his brother only because Stan ruined his chances into getting the best university, but that was f*cking long ago.
And well currently, you and Ford tried getting everything back to normal but from the house of a true scientist, turns out to be now a tourist trap which is called: "The Mystery Shack" after Stan stole Ford's identity, but we're gonna ignore that because it's setteled that after summer ends which means their great-niece and nephew will leave, Ford would kick Stan out, which your strongly against, poor Stan.
But well, you were somehow the kids favorite person so far, maybe because you were still pretty young, close to Wendy's age who was the employee together with Soos. And because of Dipper's curious spirit.. You, Ford and Dipper made a pretty good trio, loving science and being good at it while also trying to unravel all of the secrets of Gravity falls together, and by the journals Ford written years ago.
And right now, it was late at night again, yet, none of you were sleeping, as the trio was in the laboratory. Dipper "reading" the 3rd journal. Ford, was doing something at his desk, writting and scribbling away papers or his drawings and You were looking throu the microscope, when you noticed that Dipper had the journal upside down, sometimes glancing at you.
You: "Dipper, the journal is upside down." you chuckled.
Dipper: "f*ck.." His cheeks reddened from embarassment, as he quickly flipped the journal.
Ford: He just laughed. "Damn.. really?"
