Dipper got up from his chair, his fist clenched. If there was one thing about him that could be considered like Stan, it was that he could never think straight when his family was threatened. Especially his sister. Mabel... she was the most important person in his life. And he would never let anything happen to her.

"I'm warning you, Bill. Do not involve her."

Bill only laughed. There was sound now to the image in Bill's eye, her screams pushed him over the edge and he lunged for the demon. He hit the black stone near the demons hat before leaning in close, his voice becoming cold.

"Stop it."

The demon simply lifted his hand up and tapped Dipper softly in response. A burst of energy then pushed the man back. It was almost diffusing, the soft floating journey to his seat. Something was very careful about it. Gentle.

"Aggression? Wow. I'm so scared Pinetree. So scared. Really. But you know, not really. Hah!"

Dipper let out a hard breath.

"Just tell me your terms." He said harshly.

Bills hand lit on fire, that familiar flame from all those years ago, and he held it out.

"You will find a way to get me out of this backwater town, you will not let anyone try to kill, erase, or displace my being in this universe... or any other. You will help me hunt down that fat stupid cherub, and I will weaken myself enough to be... boring. After all that, I will leave this dimension until someone lets me in again."

Dipper really didn't want to do this. He really, really, really didn't want to do this. But, he needed to keep everyone safe.

"How do I know you're going to keep your end of the bargain Bill. How do I know you're not just going to destroy everything once we let you out."

The demons eye crinkled in a smile like way. He lifted his hand up and the fire formed into a humanoid shape.

"I'll lock half of myself in you and bind the other half to a toy. "

"A toy? I'm not letting you possess anyone."

"Don't worry babe. It's not going to be a living person or a dead person for that matter. Promise."

Dipper bit his lower lip, he dug his nails into his arm enough to break the skin. His eyes flicked to the chair and desk again, they were singing 'Kiss from a Rose' now. They had been singing love songs this entire time. That's just weird he thought. Bill must have been trying to be romantic. He couldn't possibly be serious about this. Dipper's eyes then flicked back to Bill.

"What's going to happen to me."

Bill pointed his finger at Dipper's chest like a gun. He made a fake shooting motion.

"Don't worry about it, its nothing mind-bending. It's just half of my incomprehensible energy, it will be mindless actually. I'm going to sit it in a pocket dimension near your heart."

"Why my heart?"

Bill blinked, it was a slow purposeful blink.

"... There's no reason why. Anyway, its more of an insurance type thing. It ensures I keep my end of the deal. And that's a rare special I came up with just for you. I've never done that, ever. And it also ensures that you keep your end. If something happens to me, that energy is going to go off." Bill's eye turned red as he leaned forward. His voice then morphed into something dark and guttural, "You do not want that to go off Pinetree. Trust me."

Bill then held out his hand again for him to shake it, he practically sang the question.

"Do we have a deal?"

Dipper looked down at it, this would be the third time he ever took Bill's hand. He never had a good experience with Bill. Not once.

"Alright." He whispered.

When their hands came together it was warm and soft. The fire ran from Bill's hand and caressed his own. Bill then laughed. It was a joyful, crazed, and unnatural sound. He let go of Dipper's hand after one more shake. Then he floated up, the air behind him tore apart into the shape of his body as he did.

"Nice doing business with you. I'll be seeing you soon. Real soon."

Dipper was now alone in that office. Well, mostly alone. The screaming cats and the singing furniture remained. He got up, walked across the cats, and slammed the door shut as he left. He felt something crunch under his feet, looking down he found a bouquet of flowers. Just a regular normal set of flowers.

They were beautiful.

He scowled, sneering at them, before violently kicking the flowers across the hall. Their delicate petals spread around the ground on impact.
