Merry Christmas!

"WHAT THE FUCK?" Wendy said in the doorway, seething.

"We're doing this again?" Dipper said, his mind numb. He was getting the clone treatment twice in one day?

"Oh fuck, oh fuck." The Wendy on him, the naked Wendy, said, eyeing the clothed one nervously.

It didn't take a genius to figure out which Wendy was real.

Dipper shoved the fake Wendy off of him, disgusted with himself. How had he been fooled so easily? He tried to discreetly get his underwear on.

In the meantime the real Wendy had produced a gun, and had it trained on the fake.

"This will kill you just as dead as water will, I'm guessing." Wendy said, her eyes never leaving the fake. She shuddered. "This is so disgusting. Why me? And what were you doing, Dipper? Ugh, I can't believe you've seen me like this! Forget you saw anything, and maybe I won't kill you. I'm getting tired of freakin clones, man."

The fake Wendy stared daggers at the real one. "You're wrong." She said softly.

Dipper grabbed a half empty water bottle that was sitting along the wall. He didn't know who had left it there or how long it had been there, and frankly he didn't want to know.

"Wrong?" Wendy asked angrily. "How are we wrong? Are you a fake of someone else that looks exactly like me or something? Dipper, do I have a twin?"

"Nope." He said, unscrewing the bottle.

"Exactly." Wendy said. "Splash her."

Dipper sent the water flying at the fake. It splashed over her face, causing her to close her eyes for a moment. Water droplets fell down her face and hit the floor with the barest of taps.

Then the fake Wendy's eyes opened, and she grinned.

Dipper was confused. She wasn't melting. So did that mean she wasn't a clone after all? Then what was going on?

"I said you were wrong." The fake Wendy said, slowly rising to her feet. Dipper's eyes couldn't help but turn to her bare breasts, but he forced himself to focus on the problem at hand. He couldn't get distracted. "You were wrong about me being a clone."

"Then what are you?" Wendy asked.

"You mean you don't recognize me?" The fake asked, sounding hurt. "You locked me in here after all."

It suddenly came to Dipper what this thing was. "Wendy, get back-"

"Maybe this will help you remember." The shapeshifter said, suddenly morphing into a gigantic, morpheus insect like creature.

Dipper remembered when he, Wendy, Mabel, and Soos had come down here the first time, and they had come across a man they had thought was the Author of the Journals. But it turned out to be a creature masquerading as a man on the logo of a can of beans.

That had been what Dipper was worried about when he had arrived here, he just hadn't realized it. The shapeshifter they had frozen was gone.

But here it was now.

Whether it was surprise or fear that held Wendy's hand, Dipper didn't know. But the creature took the hesitation to charge forward with inhuman speed, throwing Wendy into the opposite wall. Dipper took a step forward to help before stopping himself, not really sure what he could even do against this thing.

Wendy fell with a slump, unconscious. The gun fell from her hand, skittering to the floor. Dipper dove for it, but a strong mandible yanked him back.

"Uh, uh." The shapeshifter said. "I have other plans for you. Or rather, my new boss does."

There was a sharp pain in Dipper's head and he blacked out.

Dipper woke up with a very bad headache. He opened his eyes slowly, wincing from the pain. Where was he?

He looked around, trying to figure out his location so he could get some sort of plan started. He was in a small room, much like the one he had been when Wendy had broken him out. Had the shapeshifter brought him back? Why?

Sitting in a chair was Wendy. Or rather, he thought it was the shapeshifter in the appearance of Wendy. They noticed him waking up.

"Ah, there you are. Sorry about the bump. Just needed to get out without any struggling."

"What is going on? Do you work for Gideon?"

"Good deduction, Dipper. I've been spying for him a while now, blending in with the group and keeping him updated on what they are up to until he's ready to squash this little rebellion they have. But you changed things. Gideon wants you."

"He wants me?" Dipper asked, confused. "What would Gideon want with me?"

The fake Wendy glanced at the door. "I think its someone else that wants you, but he wants to keep them happy."

"Mabel?"

They glanced at the door again. "I didn't tell you anything."

Suddenly the door opened. In walked a short but muscular man with unmistakable hair. Gideon had really grown into his own. He still carried the same swagger as he approached his captive.

"Dipper! I have been waiting quite a while for this moment!" Gideon smiled at Dipper like a cat stalking its prey. "We have been making some advancements that will go a long way into achieving our goals, and we finally have what we need. You, Dipper. We need you."

Dipper had an uneasy feeling about this. He wasn't sure what he would be needed for besides making Mabel cooperate with whatever Gideon wanted from her. What did he want from her? Or was there some other thing Gideon needed Dipper for that he just didn't know about?

"You, get out." Gideon said, indicating to the fake Wendy.

Wendy got up, shrugging. "Whatever you say, boss." She glanced back at Dipper. "Hey, it was fun. It's very interesting finding out what the human body is capable of. I'll need to try this sex thing again another time."

Dipper almost gagged. He hadn't even considered that everything he thought he had done with Wendy had actually been with the shapeshifter. He had almost gone all the way with that… thing. He shuddered. Better not to think about it.

"Guards, bring her in!" Gideon yelled into the hall that the fake Wendy was retreating to. In walked a pair of hulking giants, and being escorted, was Mabel.

"Mabel! Its really you!" Dipper exclaimed.

She glanced at him nervously, then at Gideon. She seemed afraid to so much as greet him.

Dipper felt his anger rising. What had Gideon done with her?

"What do you want, Gideon?" He asked, trying to sound braver than he felt.

"Oh, just a test." Gideon held out his hand and one of the guards handed him something. It looked like a cross between a gun and a needle.

"What's that?" Dipper asked, wary.

"The test, obviously." Gideon replied. He made his way over to Mabel. She didn't resist as he injected whatever was in that thing into her arm. He quickly took it out and walked over to Dipper. Dipper leaned away, not trusting Gideon.

"Dipper, I could just make them hold you down. This is going to happen either way. Just show me your arm."

He was right, Dipper saw. There wasn't really a way out of this. He stuck his arm out, and Gideon wasted no time injecting the device into Dipper as well. He felt something rush into his veins, but had no idea what.

Dipper glanced over at Mabel. Her eyes were closed, and she seemed to be swaying slightly. What had Gideon done to her?

Gideon and the two gigantic guards walked out of the room, leaving Dipper and Mabel alone. Before he closed the door, Gideon whispered to them, "You two have fun! If this works, we are only a couple steps away. Don't let me down." The door shut with a click.

Mabel was now panting, which seemed familiar to Dipper. He had seen this reaction just a little while ago, after all. It couldn't be, could it? Not with Mabel. His sister. He couldn't imagine it.

Yet he couldn't miss her hands start to drift, one at her chest, one further down.

And worse, he was beginning to feel something as well. His vision and thinking were getting hazier, and he felt himself swaying, much as Mabel had been before him.

"What… was in that?" Dipper asked, looking at the spot on his arm where Gideon had injected him. "What are they doing to us?"

Mabel didn't seem to hear him, as her wandering hands became more obvious. He could tell exactly what she was doing, how she was feeling.

He knew, because he was starting to feel it himself.

Dipper felt himself begging to grow hard as he watched his sister. This couldn't be happening, could it? Not with her. Mabel was… Mabel was…

It was growing harder to think, easier to watch, easier to just enjoy. What was he worried about again? Something about his arm, but he could figure it out later. Now he was a bit…

Distracted.

"Dipper…"

Mabel's eyes were open again, and she was looking at him. But the look wasn't the kind a sister normally gave her brother. It was something different. And suddenly, Dipper didn't mind at all.
