In the AMA Bill said, "... DON"T LOOK NOW, I UNTIED YOUR LACES." That means Bill is the Invisible Wizard who unties Dipper's shoe laces. In this closet are boots with triangular cuts, so Bill has a link here. How did Grenda manage to make out with Bill? Unknown, but he did say, "You monster" to her later.
