That has to be my fav episode.

And also in that scene, I've been wondering about what Gideon said right after that:

"You have no one to protect ya now!"

Wendy wasn't in that episode, but this is one thing I don't suspect her of. But it would still have to be someone being with Stan for years. So it could be Soos, because we don't know yet how long Soos has been working with Stan. I just realized I might should worn you that my posts on these sites tend to be long. But Soos doesn't strike me as a suspicous guy, even on a show like Gravity Falls. But it would have to be someone Gideon shrinks in the episode. That leaves Dipper and Mabel. But they haven't been with Stan for years. Alright this is my shortest post ever.
