So Dipper, now around the age of 17, returns to Gravity Falls for another summer. Mabel was with Candy and Grenda and the two Grunkles were still on their fishing trip. The others, well who knows. Dipper heads to the Mystery Shack but once he walked in, he heard something, like someone was hiccuping. He sets his bag down and heads upstairs, but once opening the door to the attic, he sees the one person he didn't really need to see the first day back.
Bill is human in this!
