An Unexpected Visit

It was a very sunny morning. Dipper and Mabel, now both 16, are staying at the Mystery Shack for a couple of months. Dipper, being the nerd that he is, is sitting in their room reading a fictional adventure book while Mabel is outside being Mabel, playing in the autumn leaves. Dipper watches her through the window and smiles as she runs around throwing leaves in the air and shouting happily. She rolls around on the ground and Dipper laughs, opening the window. 

"Hey, Mabel! How old are you, again?" He asks. 

"Old enough to still be doing kiddy stuff!" She replies.

"Yeah. You keep telling yourself that!" He says as he shuts the window.

He continues to read his book when, all of a sudden, a beam of yellow light appears and levitates everything in the room. Dipper keeps a straight face as he knows what this is. A person begins to form and clothes starts forming around them. It's Bill Cipher in human form (and he is wearing what you see in the image above and it's the same with Dipper, too).

"Do you always have to make such a dramatic entrance?" Dipper asks.

"Of course, Pine Tree. People need to know just how great I am" Bill replies.

"But no one else is here but me, so, what's the point?" Dipper questions.

"Oh, Pine Tree. You were always the reasonable one. I just came to see you" Bill explains.

"Oh, yeah? What for?" Dipper catechizes.

"Ugh! So many questions, Pine Tree! But, if you must know, I have, once again, trapped your family" Bill says quickly.

"You did WHAT?!" Dipper asks angrily. He rushes to the window and is unable to detect Mable but sees a few leaves gliding around from when she had previously played in them. Dipper looks at Bill angrily.

"What? It's just business. Don't take it personally. But I won't let them go unless you accept my offer" Bill clarifies.

"Fine. What is it?" Dipper asks reluctantly, putting the book down and paying attention to Bill.

"You're a good boy, Pine Tree. You'd never do anything to hurt anyone, you would give up your only chance of happiness for your sister and, most importantly, you are very obedient" Bill grins.

"So, what do you want from me?" Dipper asks eagerly.

"I want you..." Bill smiles. "...to be...my...slave" he finishes.

"YOU WANT ME TO WHAT?!" Dipper yells.

"Keep it down, Pine Tree, yeesh. You don't need to freak out. I promise I'll let your family go and you'll get something good out of this" Bill says.

"What do you say, Pine Tree? Ready to relinquish your loyalty to your new master?" Bill smiles and holds out his hand.

Dipper hesitates for a moment. He didn't want to go along with this but he knew what was at stake here. He hangs his head down and sighs. "Fine" he says, shaking Bill's hand.

"Excellent!" He exclaims.

"You're family is free to go" he says as a collar appears around Dipper's neck and his clothes disappear, causing him to blush.

"And you're coming with me" he smiles and tugs his collar.

 The two disappear in a white cloud of smoke before Mabel comes rushing into their room. Before she could reach them, all that's left is a small amount of mist on the floor. 

"Dipper!" She yells as she get's down on her knees and picks up his hat that was left behind, hugging it. "Oh, Dipper..." she whispers as a tear runs down her left cheek.

Meanwhile, Dipper finds himself in a small room with a double bed, a couple of drawers, a closet, a window above the bed and a light hanging from the ceiling but there's no door. A leash is attached to his collar and Bill is holding the other end of it whilst leaning on his cane. 

"This is your new home so get comfy. You'll be here for a quite a long time" Bill smiles.

Dipper rolls his eyes and Bill starts walking to the bed, pulling the leash and Dipper follows.

"For our first order of business, I need you to get on the bed" Bill explains. 

"You want me to what?" Dipper asks, obviously not paying attention. Bill sighs.

"Get on the bed, Pine Tree" Bill demands, again.

"WHAT?! WHY?!" Dipper yells. Bill clears his throat.

"Oh, come on. It's not that hard. Stop being so dramatic" He asks. Dipper sighs.

"Fine. Whatever" he says as he gets up on it and sits cross legged.

"Lay down" Bill orders. Dipper grunts and lays down.

"Let the fun begin" Bill smiles and snaps his fingers. Dippers sight becomes blurry before he closes his eyes and falls into a deep sleep.
