The Gleeful's

Summary: Living life as teenagers, Mabel and Dipper discover thing's about themselves, that don't make sense. One night they overhear a conspiracy that makes them question everything they know.

Author note: I love the idea of the Reverse Pine Twins. I know there are stories out there where the Reverse Twins make their way to Gravity Falls. But has there ever been a story where both Marbel and Dipper find out they are, the Reverse Twins?

I do not own Gravity Falls.

Enjoy!

It had been 3 years since Dipper and Mabel Pines left Gravity Falls, however they weren't as close as they used to be.

Entering High School, had separated them.

Dipper joined the Supernatural and Maths club while Mabel, because of her peppy personality joined the cheerleader's.

They were both so busy, that if it wasn't for the fact that they live in the same house, they would rarely see each other.

Society was tearing them apart and they both were painfully aware of that.

But they were still trying.

Only to find out, what made them click as kids seemed to have taken a vacation and as a result, things were now awkward.

They were honestly afraid that one day they would grow so distant that they would hate each other, just like their Uncle's.

They had nothing to talk about, that could connect them to each other like when they were kid's.

But now it was the summer holidays and both of them were determined to put their lives aside and find that special bond that they grow up with.

Who know that this summer would be so interesting for them?

One day, they both woke up with the grandfather of all colds.

Who know that they would both get sick at the same time, when it was toasting outside?

It was so bad that even the slightest movement, made them feel like dying.

Of course, the unusual cold, made their parents worry about them but luckily it cleared up the very next day.

And then Mabel set the bath tub literally on fire.

With the water still in it.

"DIPPER!" His sister Mabel burst through the door in a bath towel, startling him, the next thing he know, she was dragging him to the bathroom, where he saw the water in the bathtub on fire.

Since when did his sister become a science whiz?

"Dipper, I don't know what happened" Mabel said, in a panic tones. "I was just thinking about roasting marshmallows when the water in the tub suddenly caught on fire!"

"Mabel" Dipper began but Mabel had gone into full panicky mode.

"Dipper. Please tell me you can fix this!" Marbel said, "Our parents are going to kill me!"

"MABEL" Dipper said, louder.

"I can already see myself getting a nasty job just to pay them back for the damage-" Mabel continued.

"MABEL!" Dipper yelled, finally getting her attention.

"What?" Mabel said.

"Your eyes are glowing blue" Dipper said.

"Huh?" Mabel said, running to the only mirror in the bathroom, to find her usual black eyes were now blue and glowing. "Whoa, this is so freaky"

She wasn't actually freaked out, but she had been around her dork of a brother to know the signs of superpowers.

Did that mean she had the power to set thing's on fire now?

Luckily Dipper could put out the fire, before their parents got back and being the more logical one, he was determined to see if his sister truly had superpowers and to what extent.

But even he couldn't predicate that his sister Mabel wouldn't be the only one to develop an ability.

It was very easy for Mabel to set anything on fire, once she realised she could do it with a mere thought and Dipper was stuck with clean up duty, trying to hid it from their parents.

And then he suddenly thought after one too many close calls that he wanted the fire to go out because he didn't want to drench another thing, in water.

As soon as he said that a gust of wind came in, putting out the fire and Mabel gasped seeing her brother's eyes had become blue eyes well.

They both had abilities.

And to both of their surprise it wasn't just fire and wind, just by merely thinking about stuff, they could manipulate the very fabric of reality.

It didn't take long for Mabel to build Waddles, his dream home that she couldn't afford, using her new power's.

While Dipper tried to figure out why they both suddenly have power's, long after they had left a supernatural town called Gravity falls.

Shouldn't it make more sense, that they would both develop these power's shortly after they got home, considering how much weird they put their bodies through?

And yet three years later they both suddenly had supernatural ability's after coming down with the worse cold they had ever had, in their lives.

He was willing to bet that they both came in contact with some spiritual object despite living in such a normal town but the only problem was, was that he had no way to prove it.

But even Mabel know that they couldn't keep their powers hidden forever.

The more they used their power's, the longer it took for their eyes to turn back to normal, Mabel was obsessed with her new-found powers and had taken to wearing shades.

She couldn't wear them forever.

Eventually they would both have to come clean.

But perhaps they would come clean to their Uncles, first.

As luck would have it, both their uncles were going to stay with them for a few days.

Each month, they would get a card in the post, telling them how great the two were doing together as they try to reconnect with each other.

They would tell their Uncles when their parents weren't around and then go from there.

Who would have guessed such a thing would happen on their first night with their Uncles in their house?

"And you're sure, they haven't awoken any abilities yet?" The voice of the their Grunkle Stanford Pines, said.

Both of them wouldn't have heard him if not for their suddenly sharp hearing that they forgot to turn off.

"I honestly feared that their limiters were being taken off, when they both suddenly fell ill" The voice of the father said, waking them up fully.

What was going on?

Both Dipper and Mabel looked at each other.

"To think this family has such a secret." Their uncle Ford Pines said. "I couldn't believe it, when Stanly told me. To think those two innocent children were-"

It was at this point, that both Dipper and Mabel blazed with curiosity and know they couldn't go back to sleep, instead they decided to use their powers to ease drop.

"Hey, don't look at me" Stanford Pines said. "For once, I wasn't the one who went through a demon book hoping to revive my dead grandkid's"

What? Both Dipper and Mabel thought.

"We just couldn't stand losing them" Their mother said, almost in tears. "To think both of them would live just for a few weeks after they were born. When they died, it was like the world ended for us. That's when we found that book. There was a spell to revive for them and we had to try it."

"But it didn't exactly revive them, did it?" Ford Pines said, he knows that bringing back someone from the grave was a grave sin that a human being should never dabble in, who knows what the consequence will be.

"We were just so happy to see them alive again" Their father said, "We didn't know, that we didn't bring back our children's souls but two soul's that shouldn't be here. I almost had a heart attack when Dipper began to lift the couch when he was a toddler and Mabel started changing her hair colour."

What? Both Dipper and Mabel thought, it sounded to them that their abilities weren't new.

"And then those terrible dream's, began." Their mother said. "In the dreams, a powerful and frightening being want's its children back. Every time, both Dipper and Mabel use their ability's, the being got closer. We were both losing sleep, every time we would fear going to bed and wake up fearing for our lives"

"Then you should have sent them back to where they came from" Ford Pines said, he know all too well the dangers of venturing out into the unknown, there could be creature's even more terrible then Bill Cipher, out there.

If this family had taken something that incurred the wrath of such a being, then they needed to give it back as quickly as possible or the whole world could face destruction.

"We tried" Their father said. "But there was nothing in the book that told us how to reverse it, the dreams were getting worse. There were times that I thought about killing the both of them, if it meant peace."

"And then we saw a section on how to seal powers." Their mother said, "We did it and the dreams went away." For the first time since they had done the ritual, this was the reason why they slept so peacefully for over a decade.

"And they have started up again, haven't they?" Stan Pines said.

"They started when the twins became sick." Their father said, "I fear that the seal we put on them has weakened. If they discover they have abilities and use them, they would attract that being once again. Both of them are no longer kid's anymore. What are we supposed to tell them when we want them to go through the same ritual again, just to make sure their powers are sealed up tight?"

"Is that why you both invited us here?" Ford Pines said.

"You are both into science and the supernatural" Their mother said, "We were hoping that you could come up with a plausible excuse to get them to do the ritual. We're not confident enough, to tell them a lie that wouldn't have a hole in it."

"So... what you're saying, is that. If they don't do the ritual, we would literal have an all-powerful being at our doorstep, which is less likely to be friendly" Ford Pines said, if those two find out they had power's, at their age, it would be impossible for them not to use them even if they were told not to.

It was at this point that both Mabel and Dipper turned off the sharp hearing.

There was a long silence in the bedroom.

Tears rolled down Mabel cheeks.

She couldn't even remember the last time she cried so hard.

She couldn't believe her ears.

She had just found out her whole life was a lie.

Was she just a replacement for the real Mabel Pines?

Who was she?

Dipper wasn't so sure either.

His whole life, he had been told that he was a Pine's and he never doubted that, until now.

Did that mean there was somebody or a couple out there, who had lost their children and they had been living with their kidnappers the whole time?

No.

It can't be true.

If it was true, then that would mean he was living somebody else's life.

He turned on his super hearing and he felt his eyes heat up, hearing his parents and Uncle's still scheme on what to tell him and Mabel, so, some unknown entity doesn't come to kill them.

He could hear his sister crying quietly beside him, she too had turned on her super hearing from denial.

Neither of them could sleep that night.

#Morning#

Everybody in the house couldn't help but notice how it was 10 in the morning and neither Mabel or Dipper had come down to eat their breakfast.

So, Stan, who was grumbling, was sent up to drag them both out of bed.

He walked up the steps and got to the door, shouting. "Kid's wakes up! I hope your both decent because I'm coming in wither you like it all not."

Seconds later there was no answer.

Stan frowned and kicked the door down, without regard for personal property.

His eyes soon met the changed room of Mabel and Dipper Pines, the bed's that were once, side by side, were now each at the end of the room, a line was drawn in the middle and curtains were separating both parts of the room.

The result of not having enough money for another room and their changing body's.

He sighed, it used to be so easily to wake them both up, but now he had to go from one end of the room to the other.

So, he decided to start with the easiest to face.

Mabel.

"Who wants to spend the day with her Grunkle?" He asked as he draw the girly curtains back, only to get a shock.

Mabel bed was empty.

Even Waddles bed that was near her bed, was empty.

He quickly rushed to Dipper bed, suddenly having a bed feeling.

It was empty.

Every single bed was empty.

They weren't in the house, so that meant they were outside.

Nobody had seen them go outside, so that meant they had sneaked out.

But why?

Stan made the mistake of looking outside.

The once clear blue sky had turned blood-soaked red and a large crack ran across it.

Mabel and Dipper were using their power's and the being was getting closer.

And scene!

Please review this. If there are at least 10 or more followers I will make this into a story because I really like Gravity Falls.
