Hey guys I just wanted to do a fic on a theory thats come up. If you haven't heard Bill may not be dead. He is inside the body of a bird. If you want to hear it in better explanation check out Vailskibum94's Channel. It is a fairly recent video. Also thank you to Jet Engine for letting me use her characters. You rock! And without further ado. Here is the story.

Bill Atbash Cipher swore he would get revenge one day. It would be easy. He only needed someone to touch his hand. As he knew he couldn't persuade someone in this form. Maybe some dumb meat sack would shake his hand.

Soon after he thought this a small yellow bird with a small splotch of black and white on it's chest landed on his hand. "Well it's not the best but it'll have to do." He thought. He possesed the birds body and flew off laughing quietly as not to draw attention to his new form. He had to lay low for a couple days.

A day or two later...(whichever is more convenient for you)...

Bird Bill landed on the windowsill of the kids bedroom to see that they were gone. He cursed in a way that only demons knew even talking in his bird form. He tried to see a future outcome. He knew it was pointless because of his bird body however. He flew around resting on a tree branch that was near the two kids leaving on a bus.

He watched as the four Pines got "emotional". He watched as they left. A few days later the other two left as well. Every Pines in the state was now gone. He was Pineless.

He knew that there was a way for him to create a future vision. He saw a blue old man do it once. But he couldn't do it without getting into the basement. Or without arms. Plus it was hard to get into the Shack without a proper body.

The problem was he couldn't leave this body and still have physical form. So he had a choice. Stay in the stupid form he was in. Or go back to his old form and posses someone through the MindScape. This was an easy choice to make.

He thought over the two for a minute. He pondered the choices while perched on a pine tree. On one hand McGucket was now known to be a smart person who almost the whole town knew. Which would make it kinda hard to posses him and get by with acting like he was him. On the other hand McGucket still had a crazy side to him and he had connections to people in high places.

Then there was Susan who had the lazy eye. She was a tad crazy from when the blindeye society was always wiping her memory. Sunglasses wouldn't be weird for her. Seeing as no one would think otherwise since she was a little bit weird.

He decided to posses Susan. An easy target. He flew down and landed in front of her. "Well hello there bird. Would you like to be a snack for my kittens?" She asked. "No but could you open your hand." Bill said. "...Ok!" She said not questioning a talking bird and opened her hand. Bill left his bird form,entered the MindScape, and grabbed her hand and pulled her out of her body.

He had the body. He just needed to go while everyone was asleep at the Shack.

Later that night..

"Ok just gotta sneak in." Busan said. He opened the door and walked in. "That was easy." Now all he had to do was input the code to the vending machine. Easy. The shape of a 'C'.

The vending machine opened and he stepped inside and closed the door behind him. Not checking to see if it was firmly closed. Now that he was in he could use the elevator to go to Ford's "secret" study to grab a few potions to mix up something to make a future vision. He grabbed everything and mixed it together. He labeled the potion in case he lost it and drank it.

5 minutes later...

Bill saw the future and it wasn't good news for the Pines. He saw the Pines and their "entourage" jump into an interdimensional a triangular headed kid jump through the portal and right back through. He saw an El Diablo speeding out of the town packed with many people. He also saw Question Mark try to grab a golden cane. Lastly he saw the Pines and all their friends being trapped in giant bird cages. It looked like the entire Cipher Wheel was trapped. And that mutant. And a star shaped demon. Lastly he saw a blue square with yellow eyes. "Visions are never wrong." Bill said a bit too loudly.

In Soos and Melody's bedroom...

Soos awoke with a jolt. "Dude...Wha...what was that?" He listened closely and thought it was coming from the basement. He saw that the vending machine door was slightly ajar and opened it and firmly closed it behind him. He listened and heard a familiar voice coming from what sounded like the second floor. Could Stan and Ford be back?

He was curious and decided to check it out. Soos pressed the button to the second floor and he was surprised to see who was down there. Lazy Susan. "Uh...Lazy Susan?" Soos blinked to make sure he was seeing right. Bill answered with the most normal answer he could think of.

"Oh hello Qu- I mean Soos what are you doing in my house?" He said. "Sorry dude. But this is my house." Soos responded. "Oh well can you help me get out of here?" Bill answered. Soos led "Susan" outside. "See ya dude." Soos said and closed the door.

Could that be the same blue square that entered that one girls mind with His ex and Ford? What was those people's names? He thought and remembered quickly. Starclops was his old ex-wife's name and he was they're friend and the star shaped demon he saw. Then it hit him. Nadia was Ford's wife and Tad was Starclops and Nadia's best friend. The blue square.

He couldn't believe Tad would become his evil sidekick. But visions were never wrong. The vision seemed a few days from now. Which meant the entire Pines family would be in his hands. The vision is sealed. His future had been written. Since he stole a body he knew for a fact that he could go back to his form he had before the Pines defeated him. So he did...kinda.

Unfortunately he still no longer had his physical form. He could only be seen in the mindscape again unless he possesed a body. So technically he did have the same form he had before the Pines defeated him. So he had to possess someone close to the Shack. But Who?
