Hey guys! I know it's been awhile, but I've got the crossover bug and I wanted to start writing it. If you have any other questions about my other fics, please PM me. With that, this will be a Gravity Falls x Steven Universe x Rick and Morty, however the focus of the fic will be on Gravity Falls and Steven Universe. The fic will take place just after Steven has that talk with Greg about his desinty after discovering the Nora tape, while all the Weirdmaggeden drama will be over in Gravity Falls.

With this, I hope you enjoy the fic!

Disclaimer: I don't own Gravity Falls, Steven Universe, or Rick and Morty

Dipper sighed, rolling over and wiping sleep out of his eyes. It was the start of another week, and he wasn't personally excited to face another week of boring lectures and homework he was sure the teachers barely glanced at. But they were in middle school now, they had to be responsible and stuff- really Dipper felt like the gears of life were turning a lot slower since they left Gravity Falls.

Groaning, Dipper rolled out of bed and pulled up his blinds. One thing he enjoyed about being back in Californian was the constant sunny weather, Oregon was nice but it rained in the summer- well they do say that Oregonians are born with webbed feet.

Moving a way from the open window, he head towards his bedroom door to start his morning routine. Seeing as how the shower wasn't running, he figured Mabel wasn't up yet. That was something he definitely didn't miss about Gravity Falls- sharing a room with his sister. Dipper was VERY glad to have his man cave back.

"Better get started before Mabel hogs the bathroom." He said to himself and then glanced down, hearing a familiar grunt. "No offense Waddles."

Dipper's eyes widened in surprise as he finally took notice of the pig in his room. Waddles always slept with Mabel, so it was a rare sight for Dipper to find the pig in his room. "Hey boy... where's Mabel? She leave already?" Petting the pig affectionately. "Weird. She either sleeps in so late she forces to be me late, or wakes up at the same time as me and then stay in there so long that I can feel myself age."

After shrugging off his thoughts, Dipper left for the bathroom in case Mabel was still asleep and was very relieved to see that was not the case.

Surprisingly Dipper was able to shower uninterrupted, and even brushed his teeth without being rushed. While living with Mabel was fun, sharing a bathroom with her was a nightmare. Counting himself lucky, Dipper dressed himself and put on his signature hat. Even though it was cool to have the Great Dipper birth mark, it sucked when it looked like someone had played connect-the-dots on his forehead.

Eventually Dipper made his way down the stairs, once again taking notice of Mabel's peculiar absence. He also noticed Waddles was following him everywhere he went, which was also very strange- normally the pig would go back to Mabel's room and wait for her to come home. Finally getting to the kitchen, he was somewhat relieved to see his parents weren't home. Living in an expensive but beautiful place like California meant the parents had to work a lot to afford it, so breakfast and other meals without them were common occurrences in the pines household.

Looking in the fridge, Dipper sighed in relief as he noticed a plate of scrambled eggs and bacon wrapped in plastic in the refrigerator. He frowned when he noticed there had been no second plate for Mabel- she probably already ate hers though. Shrugging, Dipper began eating his breakfast and tried to recall if he finished all of his assignments. He looked down when he noticed a nudging on his leg. Looking down, he saw Waddles looking up at him with a pleading look.

"You're pretty needy today aren't you?" Handing the pig some of his eggs. "Didn't Mabel feed you before she left?" Turning to the pig's food dish, he noticed it was completely empty and had no evidence to indicate food had been there since the night before. Now THAT was weird. Mabel was normally pretty spacey, but she NEVER forgot to take care of Waddles. "Geez... I'll have to see what's up with her..."

Not having time to go the garage to find the compost Mabel kept for him, Dipper scraped the rest of his eggs into Waddles' dish. He quickly scarfed down the bacon and drank his orange juice- he decided to get a head start to school since he was almost always late. "Later Waddles!"

Dipper ran outside the door, and began his walk to school. Maybe on the way there, he'd stop Mabel and say she owed him breakfast to compensate for Waddles.

Amethyst always thought Beach City was always a beautiful site in the morning, full of colors and interesting smells. It was nothing like the Kindergarten she was formed at- the air was stagnant and barely had any discernible colors. As a quartz she was tough and resilient- but it was times like these that had made her sentimental.

As much as she wanted to wake Steven to watch it with her, Pearl had insisted that Steven get at least 7 or 9 hours of sleep to further his development. Whatever the heck that meant. Amethyst honestly thought Pearl just made up that rule to grate on her nerves, but had relented when she saw that Steven genuinely enjoyed sleeping. She'd just brag about it to the boy, to teach him a lesson for sleeping in.

"Amethyst! Get off the roof and come help us!" She groaned when she heard Pearl's annoying voice.

"Whaaattt...?" She groaned, but rolled off the rooftop anyways and landed on the deck.

Pearl rubbed her temple and groaned. "Garnet is trying to make Steven breakfast and we need help setting the table!"

"And what are you doing exactly?" Amethyst rose a brow.

"Making sure everything is in order of course." Pearl smiled. "I've been researching what humans call 'nutrition', and I've asked Garnet to make a balanced breakfast for Steven!"

"Speaking of which... where is the little guy?" Amethyst poked her nose around Pearl's body to pear into the house, noting that their youngest resident wasn't at the table where he normally was. when Garnet prepared food. "Is he sleeping in or something?"

Pearl frowned and shook her head. "No. I checked his room in case he had been, but he doesn't appear to be home."

"Weird." Amethyst put her arms around the back of her head and followed Pearl inside. "Hey Garnet. What ya makin'?"

Turning to the shorter gems, Garnet replied. "As according to Pearl's request- roasted bell peppers, scrambled eggs, and two pancakes. The exact nutritional balance a 'breakfast' meal should provide for a developing human. Steven's going to need it for today's training. Amethyst... would you mind calling Greg to send Steven back?"

"Ya sure." Amethyst went to go use the phone, while Pearl started talking about today's training routine.

"I've planned on having Steven work on summoning different shapes, of course sword fighting, and I was going to invite Connie over for some Stevonnie fusion training-"

"Hey guys." Amethyst interrupted, looking a bit troubled. "Greg's not picking up. What should we do?"

Pearl frowned and turned to Garnet. "It's not like Greg to miss our calls. Maybe we should go get Steven ourselves?"

Throughout the morning, Garnet had barely said anything and it was starting to bother Pearl. It wasn't like she spoke much to begin with, but when Garnet was silent it normally meant trouble. "Garnet...?" Pearl asked again.

Turning off the stove, she said abruptly. "We should go look for Steven. We don't want his breakfast to get cold."

Dipper was having an odd day to say the least- throughout school he had looked for his twin but to no avail. He and Mabel didn't share many class with science and math, but they shared most of their other classes and he was surprised when not only when he noticed that she was absent- but that the teacher hadn't even called out for her when taking attendance. Dipper tried to act like everything was normal, trying to tell himself that maybe Mabel was just skipping, but he could not help but feel that something was terribly wrong.

After school finally ended, Dipper rushed back home as fast as he could. Luckily he and Mabel didn't live that far from their high school, and made it home in just about 20min. Quickly opening front the door, Dipper ran upstairs to Mabel's room and threw open the door. He stumbled back at what he saw- nothing! Nothing of Mabel's anyways...

None of Mabel's stuff was in there. Not her bedroom furniture, stuffed animals, obnoxious boy band posters, hideously pink carpet and walls- nothing! Instead, it appeared to be a home office of some kind for his parents... and apparently himself judging by the Big Foot poster on the left side of the computer desk. The room itself was completely different from Mabel's room- it had a big, expensive looking computer, a big desk, and even a mini fridge at the far side of the room.

"Oink! Oink!" Feeling Waddles nudge him, Dipper looked again and noticed that Waddles' bed and toys weren't present either. In fact, it looked like it was the cleanest room in the house. A stark contrast to Mabel, who always had her room look damaged from a hurricane. Shakily standing up, he pet Waddles and slowly walked towards his room.

Dipper was feeling nauseous, as panic set into his body. Slowly picking out his cellphone from his pocket, he dialed his mother... hoping desperately that they had decided to send Mabel to an all-girls boarding school for some cruel purpose. Hopefully, his mom will just tell him that her obsession with boys had caused her to fail that physics test last week.

When the Crystal Gems arrived at the car wash- several things had surprised them, the primary one being that Greg didn't own it. In fact, it looked like he hadn't been there at all. It was an automated car washing station that was run by the same company that owned the town's gas stations, making Greg's presence completely unnecessary.

"Garnet... what's going on...?" Pearl asked, barely able to contain her anxiety.

The tallest of the trio didn't say anything, just staring at the car wash. "Sapphire's telling me he's at the concert hall, setting up for a show."

"Say what?!" Amethyst exclaimed. "That guy has some serious explaining to do! I mean, how can he just quit the car wash like that?!"

"He didn't quit Amethyst... it's... I'm not sure how to explain... my head is starting to hurt!" Garnet clutched her head, Sapphire was getting overwhelmed and she wasn't sure how long the fusion could hold.

"Garnet!" Pearl knelt down beside her, and could only watch when her friend reverted into Ruby and Sapphire.

"Guys! There's Greg!" Amethyst pointed to a very different looking Greg. He was pulling up in a red convertible, letting the wind blow through his hair. He stepped out of the car, dusting off her leather jacket. When the Gems took a closer look, they noticed that Greg looked more clean shaven and just more hygienic in general- no swat stained tank top present. The man looked at the Crystal Gems confused and walked over to them.

"Hey Crystal Gems, what are doing at my car wash?" He smiled politely.

Before Pearl could respond, Amethyst got right up to his face and started making demands. "You call this a car wash?! Where's the personal touches you put everywhere?! Like the sign Connie and the Crystal Gem wannabes made?! And where's Steven?! He's supposed to have breakfast with us!"

"Whoa slow down there...!" Greg put his hands up in defense. "I know you guys aren't involved too heavily with the town on a daily basis, but I sold this car wash over ten years ago to the gas company, so I could become a local musician for Beach City. I fell in love with this town after one show, bought the car wash from an old man practically looking to give the business away, and decided to stay. Can't say I know who Connie is though."

The Crystal Gems were speechless, this did not match up what they remembered at all. When they didn't respond, Greg continued. "And I'm sorry that your friend missed breakfast, but I don't know who this 'Steven' person is. Why do you think he's with me?"

"...What do you mean Greg...?" Pearl asked, dreading seeping into her voice. "Steven is your son. You had him with Rose-"

"Woah!" Now Greg stepped back a little. "I don't know what you guys are talking about with any of this- I don't have a son. I don't have any kids for that matter."

The Crystal Gems completely froze at this. Pearl was shaking at this point, and she quietly said: "What are you saying Greg...? Of course you have a son... you had him with our leader, Rose Quartz... she had him with you because she loved you! She chose you! Why are you saying these things?!" Pearl had pulled out her staff, but Amethyst held her back.

Noticing that Sapphire was still in no stake to talk, Ruby decided to speak up. "Greg... it's us- Ruby and Sapphire! When we fuse, we become Garnet! And that's Pearl and Amethyst! We're the Crystal Gems! Don't you remember?! We've been fighting against Home World from destroying the earth."

Greg backed up further, wishing he hadn't decided to bring his car around for a wax job. Once he was inside his car, he started the engine and looked at them. "I'm sorry- I really don't know who Steven is. I don't have a son, and quite frankly... I don't think any woman would want to have kids with me."

"Do you... remember us at least?" Sapphire managed to speak through gritted teeth.

"Well of course I do!" Greg smiled. "You guys are the Crystal Gems! You're the ones who keep Beach City safe and weird! But this is the first time I'm actually talking with you guys, you normally just stay on the beach." Greg checked his watch. "Well I gotta go set up. The concert is in a few hours and I need to do a sound check. You guys are welcome to come if you want!"

"Nah. No time!" Amethyst responded, patting Pearl's back. She was now crying, unable to take this confusion.

The Crystal Gems paid no heed when Greg drove off, no attention to the people gathering around them and taking pictures. The only thing on their mind was Steven- where had he gone?

As freaked out as Dipper was, he was still trying to maintain his sense of normalcy. If his time at Gravity Falls had taught him anything, it was not to freak out until he was sure there were no other options. He was trying to do his per-calculus homework to distract himself, but found that it wasn't working.

VVVRRR!

Jumping slightly when his cellphone vibrated, he checked his phone and saw that it was his mother. Bracing himself, he pet Waddles to calm himself. Since the pig obviously wasn't aloud in what used to be Mabel's room, the animal had obviously settled for Dipper's room. Flipping open the phone, Dipper spoke:

"Hi mom!" After his mom responded, Dipper spoke again. "I don't know if anything's wrong. I just wanted to know where Mabel was?"

Waddles lifted his head when he felt Dipper's hand drop from his head, and onto the floor. "What do you mean who's Mabel? She's your daughter and my obnoxious twin sister..." Dipper's voice was trailing off, feeling as though his chest was suffocating itself.

After a minute had passed, Dipper managed to respond again. "Yeah mom... you're right... it was just a joke. Mabel is a friend of mine..." Dipper felt his heart breaking in two, tears dripping onto his textbook.

"Have her over for dinner sometime...? Sure. I was going to help her with her math and science homework anyways..."
