Hello, I am Alpha Belmont. As you can probably tells from the title an description (and if you didn't read those, why are you here?), this is a fanfiction based on Minijen's fabulous crossover, Universe Falls, based on Steven Universe and Gravity Falls. This is specifically based upon MK 2.0, a future in the FanFiction built upon by Minijen and her fans about the children of the original main characters. Now, as much as what you're about to read would make for a fluffy one-shot, this is actually the PROLOGUE to a full blown story in the style of Universe Falls. So prepare for a lot of action, love and a serious helping of angst.

Also, this is based off work done by Cartoon Network, Disney, Rebecca Sugar, Alex Hirsch and Minijen. I do not claim complete ownership of this work, only the original elements I created. Please support both the original cartoons and Minijen's amazing fanfiction.

Also also, because this is based in the future of Universe Falls, this means there will be spoilers for Universe Falls, both what has happened so far and what is yet to happen. I've learnt a lot of stuff from Minijen's blog, and while I try to keep it vague, I can definitely say there will be spoilers. So go read the original work first and come back here and still be spoiled because I have to bring up events that happened. Cool?

Also also also (There is never too many alsos!), I am going to use the Vigenere Cipher for the entirety of this story, with the key word hidden somewhere in my author's notes.

Without further notice, please enjoy Universe Falls: Mystery Kids 2.0

Their two faces leant forward as their lips met. Finally, they were married. After all the pain and suffering they had gone through, there was one thing that kept them together. No intergalactic warlords or crazed demons of alternate dimensions could hold them back.

Everyone clapped as Steven Quartz Universe and Connie Maheswaran stood back and looked at each other. Connie cracked a smile, tilting her head a little to the side. Steven closed his eyes and chuckled, realising how far they've come. They were no longer just little scared kids, with the whole world out to get them and their friends. They were now Mr. and Mrs. Universe.

The two looked out among the crowd, who all came together for their special day. Everyone dressed up in suits and dresses, it looked like almost the whole town came along to their special day. Not that they could be blamed, it was the marriage of two people who had saved the town more times than they could count, but for just one day, Love was the only thought in Gravity Falls.

However, despite the many people sitting in front of them, the most important people were standing behind them.

The two turned around and looked at their closest friends and family, all grooms and bridesmaids. On Steven's Side, Stanford "Ford" and Stanley "Stan" Pines stood side by side, with Stan in tears, crying into his brother's shoulder, with Ford giving the two a grateful, yet embarrassed smile. Next to those two was Greg Universe, Steven's father, and the man who raised him. He looked at his son, tearing up at seeing him so grown and changed. Then there was Dipper Pines, Steven's Best Friend and Best Man, one who for so long had been paranoid and worried, had none of that then and was giving the newly weds a full smile.

On Connie's side, stood Pearl and Amethyst, smiling happily, with the both trying to hold back the tears. These Crystal Gems were not one normally for such a human event, but where more than happy to participate. Next to them was Pacifica Northwest. When the two first met, Connie never would have wanted Pacifica to be at her wedding, let alone one of her bridesmaids. Yet, their relationship grew and Pacifica gave the two a happy smile, as she rubbed the small bump on her belly, the past all behind them. Lastly, there was Connie's Maid of Honor, Mabel Pines. These might have been awkward years back, when Mabel struggled with her own feelings for Steven, but now everyone was fine, and Mabel smiled, ignoring the tears running down her face.

Officiating the Wedding, was the perma-fusion, one made of love, Garnet. After Steven had officiated her wedding years ago, she was more than happy to to marry them now. Garnet, with her three eyes open and crying, gave the two a thumbs up, signifying her long-standing approval, and wishing them all luck.

Steven and Connie would now never be torn apart, no matter what.

X-X-X-X

After a lot of the formalities were out of the way, the reception began. Everyone was cheerful, after the event a long time coming finally happened. Pearl and Amethyst both hit the dance floor, striking moves before accidentally fusing together into Opal, with her own wedding attire, though the fusion was too much in the moment to even notice. Connie threw the bouquet behind her, as it came down in the hands of Peridot, a small green gem, who screamed, wrapping up three other gems, Lapis Lazuli, Bismuth and Amber in a hug. Stan stood next to the bar, encouraging Ford to take a drink, despite the older brother's repeated rejections

Steven, Connie, Dipper and Mabel all meet up together around a table. Despite the music in the background, it's oddly silent between the four of them. Soon, Mabel decides to speak up

"Wow, things are really changing, aren't they?"

Dipper smiles, looking at the photo in front of him, before replying "Yeah, it really has." The four all look at the photo. It's a photo from when they beat back Gideon Gleeful after he stole the Mystery Shack.

Steven looks towards "It feels a bit weird knowing we're married and you and Pacifica are having a child". Mabel slaps Dipper on the back.

"Congratulations Bro-Bro, you thought of a name yet?"

Dipper laughs. "Mabel, we don't even know what gender it is yet!" The four share a laugh. They've always been the best of friends, ever since they first met. It still felt it was yesterday. Mabel and Dipper where heading towards the Gem Temple and Steven and Connie where heading to the Mystery Shack on top of Lion. Ever since that day, they've all stuck together, no matter what issues they've faced.

"Steven, Dipper, Connie, promise me that we'll never change. We'll always be open and caring, and most of all together." The three look at Mabel, emotional. They all nod in agreement. Nothing will ever change between them. Mabel gives out a sigh of relief. "Oh good, I was worried for a second." The group chuckles and Steven lies his head back in the chair, looking towards the roof. There are many ways people show their feelings and thoughts, and Steven began showing his the only way he knows how. By singing

"At last it is only just us" Steven began, drawing the attention from the three at the table. "At last we don't have to fight for peace and justice." Steven sits up fully, his hands on the table "No more evil schemes to face, All Together in one place" Steven continues to sing. He finally stands up and looks towards all of his friends, singing the next line in his song "At last we have peace and love".

The three smile. They know Steven likes to break into song, as he had learnt from his fellow gems. He was practically a walking jukebox. And while when they first met him, all Dipper and Mabel did in regards to singing was the occasional Karaoke night, they couldn't Steven hadn't rubbed off on them.

Connie stood up next to her husband, pushing her chair to the side, joining in on Steven's song. "Not knowing what the future may bring" she belts. "Whether it's pain, whether it's love" Connie sings, bring her hands to hold Steven's. "We'll stick together"

Dipper smiles, realising what is going on and sings "Not knowing what to sing." Mabel excitedly puts her hands on the table and pushes herself up, not wanting to be left out. "Whether to rhyme, Whether to move on" she says and slightly nudges Dipper. "We'll go further" the two harmonise.

The four stand up next to each other and sing in perfect harmony.

"At last it is only just us."

"At last we don't have to fight for peace and justice"

"No more evil schemes to face, all together in one place"

Exclusively, Connie and Mabel sing "At last we have-"

Steven and Dipper repeat in tandem "At last we have-"

The four come together to continue to sing "At last we have~", holding the last note.

"At last we have peace and love"

"At last we have peace and love"

The four finish their song, and suddenly a large round of clapping. They turn and realise everyone was watching them sing and is now applauding the performance.

Dipper gives of a sheepish smile, Mabel throws her arms in the air and Connie kisses Steven on the cheek, causing Steven to blush.

A bright flash, and the moment materialises as a photograph, pictured in a beautiful frame. It's being held in the middle of an attic, by a 13 year old girl. Her blond hair covers one of her eyes, leaving her other eye, brown in the open. Her purple dress is slightly dusty around the bottom, and a old, slightly worn-out blue hat sits upon her head. She looks at the photo and smiles.

Suddenly, a creek and she looks behind herself. Somebody is climbing up the ladder to the attic. Out the top comes a man with a stubble, and brown hair that's all to recognisable, Dipper Pines, now much older.

He looks at the girl and smiles. "Your mother told me I would find you up here Ava".

Ava smiles back at Dipper, replying "Sorry Dad, I was just looking around." Dipper, being slightly to big for the cramped attic, crawls over to Ava and looks at the photo she is holding.

"Ah, it's been so long since I've seen that photo. That was Uncle Steven and Auntie Connie's wedding night."

Dipper wraps his arm around his daughter, and kisses her on the forehead. He returns to the ladder and begins climbing down. Though he stops. He turns towards Ava.

"Hey, listen, me and your mother were talking. We've never taken you to Gravity Falls where we met and where we were all friends since you were little. And since the spot is available due to Soos going around the country franchising, how would you feel about us moving into the Mystery Shack and staying in Gravity Falls again?"

Dipper looks at his daughter, who smiles and wraps Dipper in a big bear hug.

"I would love to"

That was the prologue to Universe Falls: Mystery Kids 2.0 titled "At Last". I had real fun writing this chapter, writing characters I don't normally write for is sure an interesting experience. I know I do have to improve, especially as this chapter wasn't a huge show off of the character's personalities.

And I hope you enjoyed the song! I know I want to include songs in this story, but because this isn't specifically based on SU or GF, it means I have to write original lyrics. I love to do this however, so look forward to more of those in the future

Tell me what you thought of this chapter! I want to improve my writing skills, and while I do have a lot planned for this story, it isn't set in stone, and I'll be happy to change it. I'll also be replying to each and every review at the end of each chapter. For now, that might change.

I hope you enjoyed this prologue and that you will join me for this story
