You had gotten hold of the equation breaking the barrier around Gravity Falls.

You weren’t a bad person. But you had to do this. You had been controlled by Bill for eons at this point, holding out your end of the deal, and giving him this, he would hold up his end.

You had managed to get on the good side of everyone at the shack, enough for Ford to actually give you the equation.. and you didn’t actually want to give it to Bill, but you had to.

You had stolen Dippers journal and used it to summon Bill in the forest far away from everyone at the shack to give him this, and if you did, the world would most likely end…

You finished summoning him, and everything around you stopped, Bill appeared in the sky above you, looking as ‘excited’ as he always did.. he looked down at you as he floated down to be eye level with you.

“You called short stack? What could you possibly want now?”

He floated around you with his hands on his hips, you weren't a fan of the nicknames but, that’s beside the point. You have the choice to give it to him or not.. what will you choose?
