A light blue glow surrounded the Zodiacs as they joined their hands and a great beam shot out of the middle from the circle they have formed. The beam hit directly at the middle of the rift, causing to suck everything that came out from it back in.

"NO! NO! NO! NO! NO!" Bill screeched. He was holding on to the ground to prevent himself from being sucked back into the Nightmare Realm.

Finally. They can rest ea-

"What the hell?!" Stan shouted as he suddenly started to float up and slowly get pulled towards the Rift. But it wasn't only him, the rest of the Pines started to float up and getting pulled in as well. The others were shocked and horrified by this and held on to the Pines tightly to keep them grounded.

"Don't worry dudes! We got you!" Soos said as he held onto his father figure.

Bill saw what was going on with the Pines and had a flashback.

He was taken decades back. Back to when a teenage Filbrick Pines made a deal with him so that he could have the most extreme life he could ever have.

And Bill did just that. By taking out the teen's soul from his body and giving it extreme torture. He then inhabited the soulless body, and met a chick named Cassandra or something. When he had Stanford and Stanley, he knew that victory was within his grasps….

….But what he didn't know that the elder twins and the extra got some of his demonic essence… That means all four Pines here are related to him….They were biologically his kids….

And children should be punished when they misbehaved right? ~

With a cackle, he stretched one of his hands towards the Pines, successfully snatching them away from their friends and said something horrifying and dreadful.

"TIME TO GO BACK WITH DADDY NOW KIDDOS!~"

He then let goes off the ground and gets sucked back into his Realm. Taking the Pines with him….

0ooo00ooo0

"LET US GO AT ONCE CIPHER!" Ford yelled/demanded as he thrashed in the demon's grip.

Bill just tsk disapprovingly, "You shouldn't talk to your father that way Sixer."

"Ya ain't our Pops!" Stan shouted at him only for the yellow demon to laugh at him, "Oh yeah! You kiddos don't know about what really happened!~" Bill used his free hand to tap the heads of the Pines and filling their heads with the memory of the deal he and Filbrick made.

Each of them gained an expression of pure horror and disbelief, "N-No! Th-This just another trick!" Dipper said, trying to deny it, "HAHAHAHAHAHA! Sorry Pine Tree but it's the truth! That explains why you love the supernatural so much! That explains why Shooting Star loves the weirdness! That explains why Fez is so good with conning people! THAT EXPLAINS WHY SIXER WANTED TO HAVE ALL THE KNOWLEDGE HE COULD EVER HAVE! BECAUSE I'M THE ONE WHO CREATED YOU GUYS! I'M YOUR FATHER WETHER YOU LIKE IT OR NOT!"

They couldn't believe it….After all this time, the very demon who caused them so much torment was their-

"Nu-uh! You'll never be our dad!" Mabel shouted at him.

"Hmph, I am Shooting Star. And I am going to make you guys call and see me as your father sooner or later, "Bill said sharply before getting a malicious gleam in his eye, "All you guys though are way to human for my liking~ Guess we'll have to fix that!~"

He raised his other hand once more, which is now clawed, and stabbed the four in the chest but not to kill them, but to reach into their souls and make their demon half more….dominant.

The Pines screamed in unison as they felt painful changes happening in their bodies. Both elder twins started to become younger while the younger twins started to become older. Their pupils became slit, irises disappeared and the whites became yellowish. They also felt their blood literally boiling and that something was inside of it now. Their limbs darken to pitch black, markings started to form from their chests to their necks.

Ford's markings were like wires and circuits, colored green and glowing. Dipper's markings were blue and had leaf designs on them, it looked very realistic too. Mabel's markings were pink and very glittery, while Stan's markings were red and shiny.

All four panted heavily when the changes finally stopped.

"Huh, not what I wanted but I guess it will do."

The demon put them down on a floating piece of rock; the half-demons were too tired to get up due to Bill tampering with their souls just now.

"Still, you guys are defected because of your human parts. But don't worry~ As your father, I swear to fix you all up and get rid of your defective parts~"

Those words filled them with intense fear and dread. Especially to Ford, he knows what Cipher is capable of and has experienced it himself. But now he and his family were in the Nightmare Realm, his domain. He greatly fears for the lives and sanity of his family, now that Bill promised to fix them….
