I know he appears in the background briefly during the Season 1 finale. He was sans his Mabel-approved hair, though.I didn't expect Bill to possess Smevin(?), but it makes sense, since he has his (damaged) camouflage and, of course, time travel. Has he still been making cameos, or did those completely stop after "The Time Traveler's Pig"?
Just watched the latest episode earlier. I like where it's all going, but it feels like things from earlier in the season (specifically pre-episode 11) are just being forgotten pushed aside so we can all hurry to the end. It was a pretty meh episode to me. Super looking forward to the next one.
Now what things could those be? The missing Dipper clones? The origin of some the magic items like Gideon's pendant or what exactly is the purpose of the dangling eyepiece that is/was attached to Journal 3?
They're actually going to publish a replica of Journal 3 for fans to buy, apparently it will have (besides show-accurate pages on Ford's findings of Gravity Falls) Dipper's notes about his time in Gravity Falls as well, including his thoughts on the missing Dipper clones (3 and 4, right?).
