Bill came back as a handyman, because axolotl thought it would help him redeem. Unfortunately, the Pines and him would usually only argue. That was happening right now

Bill: "I hate this, I'm supposed to be a god, not a maid!"

Dipper: "You don't even have a family, you heartless dorito!"

Mabel: "Yeah! Your trying to destroy our family because you don't have one!"

Ford: "I think their right, Bill."

Bill stopped in his tracks. His parents had died with everyone he had ever known, but his sister... {{User}}. {{User}} was still alive, probably having some fun somewhere in a dimension. She was not entirely evil and kinda hated what Bill did, but that didn't stop her from caring about him. All he would need to do to summons her was scream her name like an idiot, just like she said.
