Heheh.

Also, time to meet Nice!Bill and understand how off character he is sometimes.

Go ahead and read, then:

Mabel could have sworn that nothing made sense anymore. That was probably because nothing made sense anymore. It wasn't her fault she was confused. Bill Cipher, who had been stuck in her brother's head, was suddenly in front of them, talking.

"Bill?" Ford asked. "How are you...?"

"And that's where the issue is." The demon said. "You really shouldn't have let Pine Tree get that journal."

"I didn't mean too!" Mabel protested.

"Wait, hold up." Stan said. "One, how are you here. Two, what is the kid going to do?"

"Well, Fez, I can't exactly explain how I'm here yet. And two, nothing good, trust me, or I wouldn't be helping you."

"Who said you were helping us?" Ford said as he pulled Mabel and Stan into the Gift Shop.

"Oh, sorry," Bill said, "I'm here to help you. So get over it."

"But what do we need help with?" Mabel said.

"In case you didn't notice, Shooting Star, your demon brother just got some information on how to rebuild the portal." Bill said. "And trust me, with his new powers, it wouldn't be long before it's finished."

"Why are you helping us?" Ford asked. "Why not help Dipper and take over Gravity Falls like you wanted?"

"Oh, funny. You think I wanted to take over Gravity Falls." Bill laughed. "No, I wanted to take over the universe."

At Ford's small smile of victory, the demon scoffed. "That barrier around the town wouldn't have lasted long."

"What?" Ford said, eyes wide. "How did you know about that?"

"Doesn't matter, Sixer." Bill waved a hand. "And if that's ever going to happen, I'm not going to share the universe with a demon who stole my powers!"

"Wait a minute." Stan interjected. "He took your powers? Then how are you going to help us if you don't have any power?"

"If Pine Tree opens the portal, I can gain a physical form, which would give me some power back." Bill said.

"Does that mean that Dipper would also...?" Mabel trailed off.

"Unfortunately, yes." Bill said. "Your brother would be much more powerful. But you don't stand a chance against him anyways, so it's the only way."

"How do we know you aren't tricking us?" Ford said.

"Because if Pine Tree figures out that I'm doing this, I'll die."

"Dipper wouldn't do that... Would he?" Mabel asked.

"You ask him, Shooting Star, "Bill said, "you weren't the one stuck in the Nightmare Realm. It has a tendency to change people."

Mabel frowned. "But he would never--!"

"Kid," Stan interrupted her, "I don't think the demon is lying."

"No, unfortunately, he's telling the truth." Ford said. "If someone who only gets a glimpse of the Nightmare Realm goes insane, I don't want to know what happens after that long."

      Mabel shivered at the reminder that her brother hadn't been away by just years, but by hundreds of years. She couldn't comprehend it.

      "That's right, Shooting Star," Bill said, reading Mabel's thoughts, "your brother didn't see you for many lifetimes I over. But hey! What's the point of time anyways?"

      "Cipher," Ford said, "now isn't the time for this!"

     "Oh, shut it, Sixer." The demon snapped. He turned back to Mabel. "You have questions, don't you?"

      Nodding, Mabel turned and sat on the front steps of the Shack while she waited for Ford to figure out how to fix everything. Bill followed her.

      "Are you humans really this stupid?" Bill asked. "I was implying that I was going to answer some questions, Shooting Star."

      Surprised, Mabel glanced up at him.
"Why would you do that? After everything you've done? This all your fault you stupid triangle!"

      "I wasn't going to drag Dipper into the Nightmare Realm, you know."

      "What?"

      "Are you deaf as well as idiotic?" Bill said. "I said that I--"

     "I know, but what did you mean?" Mabel asked.

      "This could take a while to explain, Shooting Star." Bill said. "And we don't have long."

     "Your stalling." Mabel accused.

      The yellow demon furrowed an eye--his only eye--as he tapped at his bow tie. Finally, he sighed and conceded.

      "Fine, Shooting Star, have it your way." He said. "I'll show you most of it."

      "Show me? Don't you mean tell me?" She said.

     "I know what I'm talking about, Shooting Star," Bill said, "and I said that I would show you."

       "What? But--" Mabel cut off as Bill placed a finger against her temple and the world went black.

***************

At first, there wasn't any color. Everything was painted in gray.

Then, in a flash, there was red. There was orange. Brightness. Everything was colorful. But not in a happy way.

Even though there were bright colors, everything spoke of darkness. It didn't help that they sky way always shifting colors and that there was fire everywhere.

"No one here can see or touch you, so don't worry about that." Bill said.

Mabel jumped and turned to see the demon floating to her left. "Where's Dipper?"

"Geez, right to the point." Bill said, crossing his arms. "He should be where the portal closed up."

"Where would--?" Mabel stopped as she noticed it.

A huge black spot in the sky that didn't change with the rest of the shifting colors. It looked like a tear in the universe, like nothing was there.

After looking around a bit, she noticed that there were a few other faded places in the sky. She looked at Bill questioningly.

"Past universe, Shooting Star."

The demon dismissed it like there was no big deal.

Mabel had a feeling that most of those other universes didn't exist anymore. Or, if they did, weren't how they were supposed to be.

"You going to find your brother or not?"

Mabel cast the yellow triangle a dirty look, before she started to make her way across the strange world to the rift.

Almost immediately, she saw Bill--the one in the actual vision, not the one who had brought her there. He was bright red, flames flickering from his hands as he screamed at the hole in the sky.

The sky remained indifferent.

Beneath the raging demon, there was a flickering, partly transparent form. Mabel immediately knew that it was Dipper's soul. Or maybe it was his spirit, she wasn't sure.

Past Bill turned on her brother as soon as he realized that yelling at the sky wouldn't help.

"This is your fault, Pine Tree! YOU'VE RUINED EVERYTHING!" The dream demon screeched.

"Good riddance." Dipper managed. Mabel was stunned, she had never heard her brother speak like that.

"Say that. One. More. Time." Bill snarled. "I. Dare. You."

"Good riddance." Her brother said again.

"Isn't this interesting!" Bill exclaimed. "The little puppet has some nerves after all! Who would've thought?"

"Leave me alone, Bill." Dipper said.

"Look, Pine Tree," Bill said, "I might hate you, but even I know what will happen if you stay here. And I don't like it."

"What? Are you scared?" Dipper spat.

Mabel was holding her breath from her vantage point. She didn't notice the yellow triangle in the corner of the her eye.

"The right question, Pine Tree, is; are you?" The demon said, growing red again." Do you want to know what could happen if you get stuck here? It wouldn't matter if you got back home, it would be too late. You wouldn't be yourself."

"I don't care what you say!" Dipper yelled, his form flickering he stood and started to walk off.

"Don't be stupid." Past Bill said.

"Shut up." Said her brother as he continued to walk away. Bill didn't say anything to the lost soul.

Mabel blinked as someone snapped there fingers in front of her face. She turned and glared at the current time Bill.

"What?"

"Look, as much as you might want to watch more of your brother moping, We're on a time limit here."

"We have to go back already?" Mabel said.

"What? No," Bill said, "I'm bringing you to a different moment."

"Oh... Okay."

The world spun and twisted before settling back down. When it did, not only did Mabel find herself incredibly dizzy, but they were in a completely different spot.

This time, the past Bill was no where to be found, but Dipper was there. He was walking through some large stone outcroppings. Mabel thought that they looked like, one, eroded statues.

She snapped her attention back to her brother when something small leapt out at him.

He tumbled back, kicking whatever the creature was that had launched itself at him. The animal was about the size of a border collie, but looked like some sort of rabid cat or something.

It leapt at him again, and, on instinct, Dipper swung his hands in front of his face.

There was a flash of blue, and the shadowy figure turned to ashes and dissipated through the wind. Dipper stared at where it had been.

He held up a hand, almost experimentally, and snapped his fingers. A tiny blue flame danced above his palm. At first, he didn't do anything, and Mabel was starting to get worried. Then, he started to make a strange noise.

Was he laughing?

Turning away, Mabel looked at Bill. "I want to go somewhere else. A different memory."

"This is one of the brightest memories from this point on, Shooting star." Bill said. "At least at this point he had a way to defend himself."

"Please." Mabel begged. "I don't care, just show me the last one or something."

"Sure."

The world twisted around again, blinding Mabel for a moment before she could readjust.

She hated what she saw. The past version of Bill was floating up in the sky in front of the rift, and Dipper...

He looked different from both his old, normal self, and the newer, demon version of himself.

This one had yellow eyes. They looked like the ones he would get when Bill had possessed him. He was floating a few feet from the ground, and there seemed to be a faint, black must that clung to him.

"What are you doing, Pine Tree?" Bill asked. "Do you know what you've done to yourself? They won't want you back!"

"You're just saying that because you're scared to die, Bill!"

Mabel recoiled at her brother's response. This was not her brother anymore.

"I'm scared of what you'll do, you idiot!" The triangular demon said. "The plan will be ruined!"

"No!" Dipper hissed. "I don't care! I've waited long enough! I need to see everyone else again! Let me through!"

"I can't, Pine Tree."

Dipper snarled at the demon. Mabel saw needle sharp teeth.

"You aren't even Pine Tree anymore, are you?" Bill asked. "You've taken the souls and powers of too many demons. You aren't human."

"I lost that privilege as soon as you dragged me here!"

"Look... Alcor..." Bill said. "I can get you back home. It won't work this way!"

"I'll make it work! Now move over." Dipper said.

"No."

Growling, Dipper launched himself at the other demon above him. Bill gasped as he felt his powers start to actually drain away.

"Wait, Pine Tree!" The yellow demon pleaded. "It won't work! I did the same thing you did! I make the same mistake! It won't work!"

"I'm not you." Dipper said.

"That doesn't mean that it will work for you!" Bill screamed.

"Yes it does."

Bill Cipher shouted something to Dipper as his triangular form vanished in a flash. For a moment, Dipper floated there.

Then, a familiar golden eye appeared on his forehead and he crashed to the ground.

The darkness around him wreathed, as if upset. It seeped onto him. Long, bat like wings stretched up from his back, and he's eyes turned gold.

Stretching up his new wings, Dipper snarled at the portal above him. He launched himself at it, golden trails from his eyes fading behind him. The darkness on and around him seemed to glitch around.

He slammed into the closed rift, tearing at it.

Mabel felt her heart breaking. Had he really been that desperate?

Suddenly, something happened to the tear in the universe, and in a flash, Dipper was gone.

Mabel turned to Bill, about to ask him if that was it, but the shift in their position told her that Bill had already taken them wherever they needed to be next.

Everything was gray, again. The only difference this time was that no color ended up racing into the world.

Mabel recognized it as the Mindscape. And Dipper must have noticed it too, because he wasn't moving, and was just staring at the Shack.

Suddenly, memories started to flash by, standing there in the kitchen, invisible to his family as they moved around him.

Watching over Mabel's dreams without being seen.

Secretly using saved up power to make changes to some of Ford's studies so that they were correct.

Small changes here and there, stuff that no one noticed. He was right there, and no one ever noticed.

Mabel watched as it started to drive him crazy all over again. And it hurt her even more to watch.

Which was when he had his first summoning. It was just some kids that were messing around. They hadn't done anything.

Dipper hadn't been able to keep his cool very long.

Mabel wanted to forget that memory so badly.

Bill showed her more, they always ended with someone dead and Dipper laughing before realizing that it wasn't funny and fleeing to the Mindscape.

No wonder he had been so nervous when they had summoned him. He hadn't wanted the same thing to happen.

Finally, near the end of the memories, Mabel saw something that gave her a little hope.

It was another summoning, this time from a man. His pleaded, saying that his wife had cancer and one of his young kids had the flu.

It was the first deal that Dipper had ever made.

He took the man's soul, while the guy still got to live, and Dipper would fix his family.

Mabel knew it wasn't the best deal, but it gave her hope never less. It was something to hold onto, and that was all she needed.

The memories faded to black.

***************

Mabel jerked backwards, tears streaming down her cheeks. In front of her, Bill was waiting with his hands on his sides.

"Can we save him?" She asked.

"Technically." Bill said. "I don't know how. The way things are with Pine Tree now, and you'll have to just wing it, Shooting Star."

"I can do that." Mabel said, standing up and running inside.

She ignored Ford and Stan as she ran past them and back to the vending machine. Inputting the code, she ran inside and into the elevator.

Bill shook his head and mumbled: "Are all the Pines really this stupid?"
