Hey, guys. I found the new teaser for Gravity falls, weirdmageddon part two. And I am hyped up.

Theories
Mabel is trapped in some sort of mindscape where she can do what she wants.
Bill called it his most diabolical creation yet. Why though?
Keyhole was alone with bill when he explained this. Why? Did he fail to do something that bill wanted or is he just bills most trusted ally?
Xyler and Craz return!
