I just came up with one because of the "Fight Fighters" episode. I noticed that Robbie looked like he would take out Dipper then and there after Dipper broke his cell phone, but when Stan looked at them through the window, Robbie waited until he was gone to say they'd continue this somewhere else. Based off of another theory, Stan might not be the author, but that Gideon thinks he is. Maybe it could be the same thing with Robbie?
