Author's Note: I'm back with a new Marvel Falls. Now, I am back with the weekly updates for this underdog of a fanfic.

Now, this upcoming chapter is going to have an entirely different conflict than from the original, but I strongly believe it'll hold up. Not to mention, it'll be a big hint to what is to come in the future of the Young Avengers series.

So enjoy this chapter. Be ready for baseballs, time travel, and pigs. Any and all comments are welcome.

Behind the Mystery Shack, Stan Pines marveled at the fairground that was being built all over the yard. Game booths, food stands, and even a ferris wheel. And his employees, niece, and nephew were helping to make it. Kamala and Dipper joined Mabel and Stan after a near accident.

"There she is." Stan said. "The cheapest fair money can rent. I spared every expense."

"I can tell." Kamala said. "That sky tram just broke off with Dipper inside. We're lucky he wasn't injured."

"That's an exaggeration." Stan said. "Anyway, I have jobs for the three of you. Kamala, you'll be manning one of the game booths; the one where you have to throw a ball at bottles to win a prize. You know what to do, right?"

"Easy enough, boss." Kamala said.

"And as for you two," Stan said giving Dipper and Mabel a clipboard stacked with papers, each with a blue "A" on it. "I've printed up a bunch of fake safety inspection certificates. Go slap one on anything that looks like a lawsuit."

"Grunkle Stan, is that legal?" Mabel asked.

"When there's no cops around, anything's legal."

"You'd make a great dad." Kamala said sarcastically.

"Now, if you excuse me, I've got my own place in the fair." Stan said.

"Really?" Dipper asked. "What are you going to be doing?"

"I'm gonna sit in the dunk tank, which I'm having Soos rig to be impossible to drop me." Stan said. "Well, good luck to you kids."

As he left for the dunk tank, Kamala turned to the twins. "Well, enjoy the fair. I've got a job to do."

"All right." Dipper said.

"Good luck." Mabel said too.

Around 12 o'clock, Kamala slouched back watching a kid throw a baseball at a pyramid of bottles. The kid failed and walked away from the booth with his head down.

"Sorry about that. But those are the rules." Kamala called out before the next person walked up. "Oh. Hey, Doreen."

"Hey, Kamala." The squirrel girl greeted back. She placed a ticket on the table. "One ball please."

"Sure." Kamala said handing Doreen a baseball. "Just so you know, you only get one shot."

"That's all I need." Doreen said before throwing her baseball hard. It hit the dead center of the bottle pyramid and knocked them all down.

"Congratulations." Kamala said handing Doreen a colorful plush that looked like a panda with a duck bill. "You win a… I don't know, but it's pretty cute."

"Thanks. But it's not for me. Tippy loves it." Doreen placed it down on the ground for her squirrel companion to climb onto the toy's stomach and sleep on it.

"So how are you enjoying the fair so far?" Kamala asked.

"Oh, yeah." Doreen said. "The snacks are awesome. The ferris wheel was a thrill. And I almost broke the bell on the 'test your strength' game. Thank goodness I was holding back."

"Wow. Sounds fun." Kamala said a little envious.

"Is something wrong, Kam?" Doreen asked.

"I don't know. It's just… This is my first fair since I moved to Gravity Falls. It's definitely much nicer than the ones I've been to back in Jersey. I hoped to experience it myself, but Mr. Pines wants me to manage this game booth."

"Can't you have someone cover for you?"

"No. Mr. Pines had me promise to stay here. He even recorded me saying that. Dipper says he did the same thing to him back at the party." Kamala sighed. "Sometimes, I wish I could be in two places at once."

"Sorry to hear that." Doreen said. "Ooh. Here comes a couple of friendly faces."

Dipper and Wendy approached the stand just as Doreen left. The red-headed teen looked up at the colorful plushes that were held up as prizes. "I don't know if it's a duck or a panda, but I want one."

"Ooh. You want to play for a special gift for Wendy?" Kamala snickered.

"Wouldn't you like to know?" Dipper asked back. "Wait. I actually am, so… Anyway, set me up." He slapped a ticket onto the booth table.

"Sure thing, buddy." Kamala said trading in the ticket for a baseball. "Just one shot, so make it count."

She slouched back as Dipper readied his shot. He tossed it as hard as he could, but it hit the edge of the table instead. It then bounced off and rebounded right at Wendy's face.

"OW! MY EYE!" Wendy screamed.

"OH, MY GOSH! OH, MY GOSH!" Dipper panicked.

"Wendy, are you okay?" Kamala asked out of concern.

"Does it look swollen?" Wendy asked showing her black eye.

"Everything's gonna be fine!" Dipper assured. "Don't worry! I'll… I'll go get some ice!"

"I think there's still one bag of ice left at the cooler on the porch." Kamala said.

"Great! I'll be on my way!" Dipper said running as fast as he could.

Dipper made it to the cooler and pulled out the last bag of ice. He ran back to the fair with Wendy in plain sight. He accelerated his run, but all of a sudden, someone stepped in his way. Both he and the grown man groaned as they fell over and dropped their stuff. Dipper saw the many ice cubes spill from his bag and scooped them all up.

"Hey, watch where you're going, man!" Dipper hounded at the man he just hit. The man was tall with a brown business suit. He had a black mustache that matched his hair.

"Oh, no!" the man yelled out. He held up a small device that was broken into three pieces. "My focusing device! Do you have any idea how hard it is to find a part this grade? You just costed me…"

"No time! Gotta run!" Dipper interrupted running past the man. He made it back to the booth, but before he could catch up, he was stopped again.

Wendy stood in front of the booth with Robbie Valentine, who was gently placing his purple snow cone onto her swollen eye. While that was happening, Kamala and Doreen watched awkwardly.

"Robbie, thanks." Wendy said in relief. "That's really sweet; the gesture and the flavored syrup."

"Yeah, I was just here in the right place at the right time." Robbie said. "You know, I've been meaning to ask you… We've been spending a lot of time together, and I was wondering if maybe you wanted to go out with me?"

Wendy thought for a moment before answering with a smile. "Yeah, I guess so."

"Sweet!" Robbie cheered.

Kamala turned and felt sorry seeing Dipper's horrified face. Behind him, a heart-shaped balloon burst into pieces.

"Poor kid."

The sun began to set and the fair started to become deserted. There was barely anybody left. Kamala decided to close up her booth and catch up with Dipper. She found him laying on a skeeball table. She knelt down right next to him.

"You okay, Dipper?" Kamala asked.

"What do you think?" Dipper replied sadly.

All of a sudden, Mabel held up a pig in doctor clothes right next to her brother. "Paging Dr. Waddles, we got a boy here with a broken heart. Come on, man. These are the jokes."

Kamala looked curiously. "Where did you get that pig?"

"You mean Waddles?" Mabel asked. "That farmer guy was offering him up if I could guess his weight. It wasn't exactly hard."

"Well, that is cute," Kamala said, "But I don't think Dipper needs a laugh right now." He turned to the boy twin. "Sorry about Wendy. Robbie just came out of nowhere and offered her his snow cone before I could say anything."

"It's not your fault, Kamala." Dipper said. "Wendy only went out with Robbie because he was there with the ice, and she only needed ice because of the baseball, and I would have had the ice if it wasn't for that jerk in the suit."

"What jerk in a suit?" Kamala asked.

"There was some guy in a suit who I bumped into on my way to Wendy." Dipper said. "He got pretty upset because I broke some toy of his."

"Is that true?!" asked a voice from behind.

The kids all turned and saw another man approach. He was an overweight man in a gray tracksuit, a bald head, and a pair of goggles.

"Did you really just broke a device that was owned by a man in a suit?" he asked.

"Who wants to know?" Dipper asked nervously.

"Wait a minute." Kamala said. "I think I've seen you around town."

"You have?" the man asked.

"Yeah. Back during the gnome attack, back at the wax statue presentation, and back at the lake." Kamala said. "You were always in the background or something."

"Huh. I don't remember all that, but perhaps it just hasn't happened yet."

"What's that supposed to mean?" Dipper asked.

"And why are you bald?" Mabel asked. "What's that all about?"

"Look, I…" The man was interrupted by a whirring sound coming from his watch. Suddenly, his tracksuit began to change colors randomly and even match certain places around Gravity Falls. He panicked and tried to adjust his watch. "AH! Sorry! This thing's been on the fritz lately!"

"That's amazing!" Mabel said in astonishment. "Are you from the future or something?"

"Uh, no! Who told you that?!" the man asked sweating from his hairless head. "MEMORY WIPE!" He instinctively threw a wipe at Mabel, which she removed easily.

"This is just a baby wipe."

The man sighed in defeat and sat down. "All right. You've cornered me. I'm… a time traveller."

"For real?" Kamala asked in a joyful gasp. "Wow! It seems that all the best superhero tropes are here in Gravity Falls!"

"That's how it usually is." The man shrugged.

"So if you're from the future," Dipper said, "Do you have, like, a time machine or something?"

"That's kinda how it works." The man said.

Dipper looked up at Robbie and Wendy who sat at the Ferris wheel. He smiled back at the bald man. "Can I borrow it?"

"What? No! Out of the question!" the man answered. He held up a square device with a screen on it. "This TemPad is sensitive, extremely complicated time equipment."

"I gotta say, that's pretty awesome." Kamala commented. "It looks retro, but if it does help you time travel, it's pretty unique."

"So who are you again?" Mabel asked.

"Blendin Blandin, agent from the Time Variance Authority." He held out a badge.

"Time Variance Authority?" Dipper asked.

"Yep. We're basically time cops." Blendin said. "My mission was to stop a dangerous individual from doing something horrible. But it sounds like you already took care of it."

"You mean the guy in the suit?" Dipper asked. "How is he dangerous?"

"Oh, trust me. He's probably the most dangerous man you'll ever meet." Blendin said before sighing. "Cant' believe I came all this way for nothing."

Dipper then had an idea. "You know, you sound like you could use a break."

"Definitely." Mabel agreed offering a ticket. "Might we recommend one of the various attractions at the Mystery Fair?"

"You know what? What the heck. I'm worth it." Blendin said taking the ticket and heading to the nearest ride. "But I got my eye on you."

Kamala looked over at the kids. "You're planning on stealing his time machine, aren't you?"

"Oh, you can't tell me you're not at least a little curious." Dipper said.

"…You got me there."

Blendin headed to the Rusty Barrel Rodeo ride, but before he could get on, Soos informed him to leave his belt behind. He did so not knowing that the kids were following him. While he was spinning around on the ride, Kamala stretched out her arm until she swiped the TemPad away.

The kids ran inside the Mystery Shack to examine the TemPad. Dipper turned it on noting all the buttons and the sketches on the screen.

"Have you got it figured out?" Kamala asked.

"I think so." Dipper said. "These buttons here can adjust the time and place which you want to go, and this button here confirms it. After that, we can go to any moment in history."

"Let's go get two dodos and force them to make out!" Mabel suggested.

"That's probably not a good idea." Kamala said. "Haven't you seen any time travel movie ever? One small, reckless change in the past could lead to an entirely new present.

"So if we want to avoid many changes, we should probably set this thing to recent events, like earlier today."

"Earlier today? Why…" Kamala asked before realizing his intention. "Oh, I see. You want to use this time machine to keep Robbie from asking Wendy out."

"Come on, Kamala. You and I both know that Wendy deserves better than that jerk." Dipper said.

"Mmm… Maybe." Kamala said. "All right. But let's try not to mess with time too much."

"Got it." Dipper said before typing on the TemPad. "If I don't miss that baseball throw, I won't hit Wendy in the eye, and Robbie won't comfort her, and they won't start going out."

"And I wanna relive the greatest moment of my life: winning Waddles." Mabel added before kissing her pig on the cheek.

"All right. Let's do this." Dipper said before pressing a button.

All of a sudden, a square, orange, door-shaped structure appeared out of thin air. Curious, the kids walked through and entered the past.

The three found themselves back in the Mystery Shack. They looked outside to see that it was once again noon, the fairgrounds was packed again, and Stan was egging everyone to try and dunk him. They had successfully made it into the past.

"Looks like we're back." Dipper said. "Now, all we have to do is be right back to where we were earlier and pick it up from there."

Kamala smiled until something caught her eye. "Uh, I think we're already covering that."

She pointed ahead and both the Pines twins gasped in shock. They hid themselves and peeked seeing another Dipper at the corn dog stand with Wendy. They each had corn dogs that were shaped like question marks.

"How do they get them into this shape? It's unnatural."

"But Dipper, they're so…" Wendy held up her question mark corn dog right next to the "DELICIOUS" sign. "Delicious?" Both she and the second Dipper laughed at that joke.

The Dipper with Kamala and Mabel gasped as he realized. "Oh, my gosh. That's the past me."

Kamala sighed. "We better not have to deal with another multiple Dipper thing."

"Guys, this is huge." Dipper said. "How am I supposed to do my baseball shot all over again if the past me doesn't know what to do?"

"Good question." Kamala said. "Unless you're willing to knock out your younger self and take his place, I don't see how…" She stopped talking when she noticed Dipper wasn't there anymore. "Uh, Dipper?"

THWACK!

Kamala and Mabel nearly jumped hearing a noise from behind them. Dipper returned dragging the body of his unconscious self who he hid in the bushes.

"There. That oughta do it." Dipper said before noticing the girls staring at him. "What?"

"Bro, that was pretty hardcore." Mabel commented.

"I had no choice. The booth is only a minute away from now, and I didn't have time to explain everything to him." Dipper said. "Don't worry. Once we change the past, it'll be all fine."

"Yo, Dipper! Where are you?" Wendy called out from out of the bushes.

"That's my cue." Dipper said before heading off to meet up with his crush. "Hey, Wendy."

"Dude, where's you disappear to?" Wendy asked.

"Eh. Thought I saw something." Dipper said. "Hey, look. What's that?"

Both Dipper and Wendy proceeded to the bottle-tipping game which past Kamala was working in. While they did that, Kamala turned to Mabel.

"So what about you, Mabel? Are you going to sneak attack your past self to win your pig?" Kamala asked.

"No need." Mabel said. "Just watching myself light up when I win Waddles is enough for me." She hurried over to sneak near the pig pen waiting for her younger self.

"So that's about it, huh?" Kamala asked. "Just me, myself, and I." Her eyes then lit up once an idea hit her head. "Hold on. If the past me is already at the stand, and Mr. Pines is in the dunking booth, then I can do whatever I want. Time to finally experience the Mystery Fair!"

While Kamala went off to enjoy the fair, Mabel hid herself as her younger self approached the pigpen where Farmer Sprott announced his booth.

"Sir, I must have that pig." Past Mabel said.

"Ah, old 17-Poundy." Sprott said. "So, how much do you think he weighs?"

"Uh, 17 pounds?" Past Mabel asked.

"Are you a witch?" Sprott asked before gladly giving Waddles to his customer. "Well, here's your pig."

From around the corner, Mabel giggled softly. "Oh, Waddles. That's so… Wait." She stopped laughing after noticing something. "I thought Waddles was 15 pounds. That's what the farmer said last time. Why is Waddles heavier?"

Meanwhile, over at the bottle booth, Dipper retrieved the ball from Past Kamala and was careful not to make the same trajectory he made earlier.

"Okay, Dipper. Second chance. Don't mess this up."

Dipper threw the baseball as hard as he could. The ball hit straight at the middle of the pyramid knocking every last bottle down.

"YES!" Dipper cheered.

His celebration came at an abrupt end however. After going through the bottles, the baseball bounced off the back of the booth and bounced back, hitting Wendy in the eye like it did before.

"OW! MY EYE!"

"What?!" Dipper gasped.

"Wendy, are you okay?" Past Kamala asked out of concern.

"Does it look swollen?" Wendy asked showing her black eye.

"That's so weird." Dipper said before noticing Robbie show up placing his snow cone on Wendy's eye and asking her out again.

Both Dipper and Mabel met back up with Kamala, who just finished the test your strength game. After getting her prize, she met up with the twins.

"Oh, hey, guys." Kamala greeted. "How did it go?"

"The exact same thing happened twice." Dipper said. "I threw the ball, it bounced back, gave Wendy the black eye, and Robbie came in to save the day. It was spooky. And I even threw it differently too."

"Well, something different happened on my end." Mabel said. "For some reason, Waddles was two pounds heavier than he was when I won him."

"Really?" Kamala asked. "That's weird. Maybe we should find the time travel guy again and ask him what the big deal is."

"No, we can't." Dipper said. "If we go to him, he'll take back the TemPad. We just need to try again. Third time's the charm."

"How hard can it be?" Mabel asked.

"I dunno, Dipper." Kamala said. "My marvel senses are tingling. Something about this doesn't seem right."

"Oh, and THAT isn't?" Dipper asked. He pointed at the Tunnel of Love and Corndogs ride where Robbie and Wendy took a ride in. Kamala shuddered at the thought of those two going out.

"Okay. I'm in." Kamala said.

Dipper, Mabel, and Kamala used the TemPad to open a new time door and walk right back to noon earlier.

Over and over again, Dipper tried to change things with Wendy, but it always ended up the same. He tried throwing with his left hand, switching positions with Wendy, and even trying to convince Wendy to not make him do it. But it always ended up the same. His ball bounced off and ends up bruising her eye for Robbie to comfort.

Meanwhile, Kamala and Mabel used their time to notice strange things. Every time they went back, they looked around and noticed differences. In one time, Soos wore two question marks on his shirt. In another, Pacifica had red hair. There was even a time where Doreen had buck teeth and squirrel fur all over her body.

At the next time jump, Kamala and the Pines decided to rest up and compare notes.

"So what was different this time?" Dipper asked.

"Mr. Pines had glasses that were shaped like question marks." Kamala said. "I tell you, something's wrong here. Every time we travel back to the past, there's always some difference."

"Not for me." Dipper said. "My attempts to keep Wendy and Robbie apart always fall short."

"Face it, Dipper." Mabel said. "You're obviously fated to have a bad day at the fair. Just like how I'm fated to be with Waddles."

"Maybe there's no thing to figure out." Kamala said. "If even time travel can't help you, what else can you do."

"I can do it." Dipper said pondering hard. "It's like there's a certain variable missing."

"What's a variable?" Mabel asked.

Suddenly, Dipper had an idea. "Ha! That's it! I figured out a way to win the toss, not hit Wendy, and stop Wendy and Robbie from going out!"

"Awesome." Mabel said. "I'm gonna go watch myself win my pig again." She turned to leave, but Dipper stopped her.

"Whoa. You can't leave. I need you and Kamala for my plan."

"Me?" Kamala asked. "What do you need me for?"

"I'll explain when we set everything up."

"What about Waddles?" Mabel asked.

"He's still going to be yours. Let's go."

After disposing of this time's Dipper, the present Dipper headed to the game booth and threw his baseball. This time, he threw it high up and let it slide down the tent roof. It threw itself off and landed on the Mystery Shack roof where Mabel was moving the gutter so it can be thrown off some more. It landed on Kamala's arm, which was stretched out and used as a slingshot to launch it right back to through Robbie's snow cone and knocking the bottles down. The baseball then bounced out of the tent and fell right to Dipper, who caught it in his hat.

"Wow." Past Kamala said before taking a prize and giving it to Wendy. "That was some awesome shot."

"Yeah, pretty awesome." Wendy said accepting the plush toy.

"There you are, Wendy." Robbie said approaching the redhead with an empty snow cone.

"Hey, Robbie." Wendy said.

"So I was wondering if, uh…"

"Look what Dipper got for me." Wendy interrupted showing off her new toy.

Robbie was so embarrassed, he raised his hoodie over his head and tightened it. "Whatever. Can't even tell what species it is. Stupid."

"What's his deal?" Wendy asked watching Robbie walk off.

"Maybe he ran out of hairspray." Past Kamala laughed.

"Ah, well." Wendy said smiling at Dipper. "Looks like I came to the fair with the right guy."

Dipper was proud and self-celebratory of his accomplishment. Once he got what he wanted, he stepped away and joined Kamala behind the booths.

"So it worked?" Kamala asked.

"Worked like a charm." Dipper said. He picked his unconscious past self out of the bushes and sat him down at a nearby bench. "Now, once he wakes up, he won't know what happened, but once he sees how grateful Wendy is for the toy, he won't care. Now, all we have to do is go back to the new present."

Kamala looked back at the dunk tank and dropped her smile after seeing Stan's question mark glasses. "Dipper, are you sure this is how time travel works? I feel like there's a piece here that we're missing."

"So there are some fashion changes here and there." Dipper said. "It's not like there's any big changes going on, right?"

"AAAAAHHHHHH!" Mabel's scream cried out as she ran back to Dipper and Kamala. "Waddles! The pig! Me! No!"

"Mabel, Mabel, calm down." Kamala said. "Think before you say each word."

"Sorry." Mabel said. "Guys, something's seriously wrong with this one! It's my past self! She… She didn't play the Waddles game!"

"The Waddles game?" Dipper asked.

"Yeah. She didn't even try to get Waddles! He ended up getting adopted by Pacifica!"

"Oh, Mabel. I'm sorry." Dipper said.

"It's okay." Mabel said. "We just need to go back and do things differently." She reached for the TemPad, but Dipper pulled it away from her.

"Mabel, wait. Look, I did the math. I need both you and Kamala to help me keep Wendy from going out with Robbie."

"Then get some other Mabel do help." Mabel said.

"There aren't any others." Dipper replied.

Kamala's eyes then widened. "Wait. Dipper's right. So far, the only versions of us that we've seen are the ones that already existed here."

"So?" Mabel asked.

"So, with all of our time traveling and repeating the same afternoon over and over again, shouldn't there be more of us? Like more futuristic versions of us that have gone back and try to fix things?"

"Hey… That's actually true." Dipper said. "Things certainly do look identical, but there are still some differences that we had nothing to do with. Not only that, but there aren't any other versions of us. It's almost like this isn't time travel at all."

"Well, it is, but it isn't." That voice caught the three by surprise.

A new man stepped out of the shadows. It was a skinny man in a business suit and tie on. He had silver hair that matched his mustache.

After taking a look at Dipper, he sighed and shook his head. "Why is it that Dippers always go for the time travel route? I thought you were the smart one?"

"Who the heck are you?" Kamala asked.

"Right. Introduction. Well, I am Agent Mobius of the Time Variance Authority."

"Like that Blendin guy?" Mabel asked.

"We do work together, but I'm on a higher pay scale than he is." Mobius said. "Anyway, you three really messed up big time."

"Messed what up?" Dipper asked. "You mean the time travel thing? Dude, it was one harmless change."

"You don't understand." Mobius said. "You diverted from an absolute point in time. It's a fixed event in the timeline that has to happen. Diverting from it could lead to unspeakable consequences."

"What absolute point?" Dipper asked.

"Hello? The baseball hitting the redhead in the face?" Mobius reminded. "You didn't notice that no matter what you tried before, it always resulted the same way? That's because it has to happen. It was meant to be."

"How is that meant to be?" Dipper argued. "Because her eye got swollen, Robbie had to come and play the hero with his snow cone and he ended up asking her out! Those two being together is the exact opposite of 'meant to be'!"

Mobius groaned. "It's not about who's going out with her! It's about what you did after you threw that baseball!"

"Okay, okay, everyone!" Kamala shouted. "Let's just calm down and think things through. Mobius, you're telling us that Wendy getting hit was necessary. Why? What's the big deal?"

All of a sudden, everything shook violently for a brief moment. Everyone turned and saw a bright-blue beam of light shoot in to the sky. The light came from the far side of the fair.

"THAT is the big deal!" Mobius shouted.

Everyone followed the light and saw it shoot out the roof of a black tent. It fell to pieces revealing a large, industrial machine which shot the beam of light into the sky. At its base, a familiar man watched in psychotic delight as it went on.

"Hey! That's the guy I bumped into before!" Dipper recognized.

"No! That's the guy you SHOULD'VE bumped into before." Mobius shouted. "But instead, you played a trickshot to impress a girl! Not exactly the outcome you expected, is it?"

"So… This is what hitting Wendy in the face would've prevented?" Dipper asked. "I don't…"

"Don't you see?" Mobius asked. "If you hadn't hit Wendy with the baseball, you wouldn't have rushed over to get the ice as fast as you did. You wouldn't have knocked that guy over, you wouldn't have made him last the last component he needed for his time machine, and THIS wouldn't happen!"

"Time machine?" Mabel asked. "So that guy's a time traveler too?"

Mobius nodded. "His name is Victor Timely, and he has the potential to be the most dangerous time traveler ever. The TVA's been trying to keep him and others like him at bay for a long time. Sometimes, like today, we had absolute points to stop him for us! But you took Blendin's TemPad and changed everything!"

Dipper looked awkwardly. "Okay. I can see how that's my bad."

"What exactly are we looking at here?" Kamala asked.

"Timely's trying to leave this time period with his own makeshift time machine." Mobius explained. "It works, but the gear he's using is going to make it unstable! It's going to take out half the country!"

"Then we gotta shut it down!" Kamala said.

"Aren't there more TVA guys who can help?" Mabel asked.

"Normally, but all our available agents were assigned to the previous timelines you entered to try and stop Timely there." Mobius answered.

"Well, this looks like a job for Ms. Marvel!" Kamala said. "Thankfully, I have my own suit to get the job done!"

Kamala reached into her pocket and pulled out her folded up costume. She jumped out and quickly put it on before rushing toward the time machine.

"HEY, TIMELY!" Kamala shouted.

Victor turned to face the hero, who grew her hand and used it to slap him away from the time machine. He crashed into his boxes while Kamala shrunk her hand back.

"Had enough?"

"Not likely, child!" Victor shouted before jumping back up to his feet. His hands held a large cannon that fired a purple blast at Kamala knocking her backwards.

Kamala recovered from the blast, only to see various stuff floating past her. A calculator, a shoe, and a hairpin. They were all flying towards the vortex coming from Timely's machine.

"I can't waste any more time!" Timely shouted. "I gotta…"

Before he could finish, Dipper and Mabel jumped onto his back and tried to wrestle him down. He threw them off, but then, a giant hand belonging to Ms. Marvel grabbed him and held him up. While he struggled in vain in her grip, Mobius stepped up to confront him.

"It's over, Timely!" Mobius shouted over the loud machine noises from the time machine next to him. "Turn it off!"

"Even if I wanted to, I couldn't!" Timely shouted. "I didn't build this thing to be shut off! You fools weren't supposed to interfere!"

"Then… How do we stop it?" Mabel asked.

Mobius groaned in defeat. "We can't. I'm sorry"

Dipper lowered his head and sighed. "No, I'm sorry! This is all my fault! I wish I never…" He gasped when one more idea flashed in his mind. He held up his TemPad and stared at it. "Wait! I think… I think that'll work!"

"Kid, what are you thinking?" Mobius asked skeptically.

"It's the only chance we have to stop Timely and save Gravity Falls!" Dipper yelled. "I think I found a… Yes! A list of stamped times we time traveled! If I just go back to when… HERE!"

"Wait, Dipper! You don't know what…" Kamala yelled, but it was too late. A time door opened in front of Dipper and he jumped through it.

Back at the Mystery Shack, Dipper, Mabel, and Kamala were ready to use the TemPad they just took from Blendin Blandin. They were just about ready to start their time travel journey.

Dipper was just starting to type on the TemPad. "If I don't miss that baseball throw, I won't hit Wendy in the eye, and Robbie won't comfort her, and they won't start going out."

"And I wanna relive the greatest moment of my life: winning Waddles." Mabel added before kissing her pig on the cheek.

"All right. Let's do this." Dipper said as he was about to press the final button.

All of a sudden, a new time door opened up and the present Dipper jumped right in. The past versions of him and his friends watched in astonishment.

"Wait. Is that you, Dipper?" Past Mabel asked.

Past Kamala sighed. "We better not have to deal with another multiple Dipper thing."

"Whoa, man." Past Dipper said approaching present Dipper. "What is going… HEY!"

Dipper took the TemPad out of past Dipper's hand and threw it to the ground. He then stomped on it shattering it into a million pieces.

"Dude, what have you done?!" Past Dipper yelled. "It was my key to fixing my mistake!"

"You'd have made an even bigger mistake if you went through with it!" Dipper yelled back. "Trust me! I know!"

"Uh… What's going on?" Past Mabel asked as the room began to vibrate and appear out of focus.

"What's happening to the Mystery Shack?" Past Kamala asked.

More and more, the room became out of focus until all of reality spun around uncontrollably around them. They all closed their eyes and expected the worst, especially present Dipper.

Suddenly, Dipper didn't feel like anything was falling apart anymore. When he opened his eyes, he gasped as he recognized where he was. He was back in front of the game booth with a baseball in his hand and Wendy standing to his left. He looked over at Kamala, who looked at him with surprised eyes.

"Did… Did we just…" Kamala asked in disbelief.

"Dude, you gonna throw or what?" Wendy asked.

Dipper looked around and realized he was right back to his original time. He smiled for a minute, but he frowned after realizing what had to happen. He took a breath and threw the baseball. Just like the first time, it bounced off the edge of the table and hit Wendy right in the eye.

"OW! MY EYE!"

"It's all right." Dipper said. "I'll get the ice."

Dipper ran as fast as he could to the Mystery Shack porch. Once he grabbed a bag of ice, he ran back and braced himself. Like before, he hit Victor Timely and made him drop his machine part which split into pieces.

"Oh, no!" Timely yelled out holding up the broken pieces. "My focusing device! Do you have any idea how hard it is to find a part this grade? You just costed me…"

"Dude, for all I care, you deserve it." Dipper said before taking his ice and ran past him. Timely gave him an angry glare watching him leave.

Dipper hoped things would be different by the time he arrived, but much to no surprise, he came back to the booth to see the exact same thing. Robbie helped with Wendy's swollen eye and asked her out. He didn't like it, but he had to accept it.

Kamala jumped out of her booth and knelt down to Dipper. "Are you okay?"

"No." Dipper admitted. "But it had to happen, right? Somebody had to knock Timely down. It is done."

Dipper's self-pity was interrupted by Mabel, who tackled him and embraced him with Waddles beside her.

"DIPPER! THANK YOU! THANK YOU! THANK YOU!"

Waddles oinked.

"He's saying 'thank you' in pig!"

"That was very risky, Dipper." Kamala said. "Going back in time to stop yourself from time travelling in the first place? That's some hardcore paradox stuff right now. You're lucky the universe isn't destroyed."

"I know, it was reckless." Dipper said. "But I had to do something. And hey, it all worked out well, right?"

"YOU THREE!"

Blendin showed up from out of nowhere and swiped his TemPad out of Dipper's hands.

"Oh! You again!" Kamala chuckled.

"Do you have any idea how many rules you just broke?!" Blendin asked. "I'm asking. I wasn't there with you. It was probably a lot, right?"

Just then, three time doors opened around Blending. More people walked through. Most of them wore black armor except for one, Agent Mobius.

"Hey, Blendin." Mobius said. "Boy, are you in a heap of trouble."

"Wait, Mobius! It's not my fault!" Blendin shouted. "It was those three kids! They're the ones who almost let Timely destroy the town!"

"I told the council that. I told them you didn't have to be punished, but it was your TemPad that the kids took on a joyride, so you have to take responsibility. I'll try to vouch for you, but I can't make any promises other than a light sentence. First thing you gotta do is pick up all the stuff scattered around time by Timely's machine."

"But wait! This isn't fair!" Blendin yelled as he was dragged away. "I'll get you kids for this! I'll go back in time and make sure your parents never meet!"

After a moment, Dipper looked at his hands. "Well, we're still here."

"Guess he forgot to go back." Mabel said.

"'Fraid time doesn't work that way." Mobius said. "I gotta say, Dipper, when you went back in time and destroyed the TemPad before you travelled back, I thought we'd be in for a greater catastrophe. But nope. The timeline fixed itself. You took a very big risk, and it paid off."

"So we're not in trouble?" Dipper asked.

"Normally, you would be," Mobius said, "But as it turns out, you're far too integral to the timeline. How or why, we don't know yet. But for now, you three are getting a slap on the wrist."

"Uh, Mr. Mobius," Kamala said, "Can I ask a question?"

"You just did." Mobius chuckled. "Sorry. Go on."

"Well, every time my friends and I went back in time, we noticed that there were different details going on, details that weren't in our control." Kamala said. "What could possibly make a pig heavier, a shirt different, or a hair a different color?"

"Oh, that's simple really." Mobius said. "You weren't just going back in time. You were going back to a certain point in time, just in another timeline. Another universe."

"What?" Dipper asked. "You guys can do that?"

"Well, yeah. It's our job to make sure nothing goes out of control. Every timeline, every universe, is different in some ways. Some very small, some world-changing. There are even some universes where Ms. Marvel doesn't even exist."

"Whoa." Mabel exclaimed. "That's pretty mind-blowing."

"So when I used that TemPad, I also brought us to other universes?" Dipper asked. "I didn't mean to do that."

"Well, that's what happens when you give the controls to someone who isn't trained to use them." Mobius said.

"So what's going to happen to Timely?" Kamala asked. "If he's dangerous, shouldn't you capture him?"

Mobius sighed. "As much as I want to, it's too much of a risk. If we bring him back to the TVA and he somehow escapes, he'll have all the most advanced time travel tech at his disposal. And if you thought he was dangerous enough with a bootleg time machine, you don't want to know what he can do with the proper tools. Don't worry though. We'll keep an eye on him."

"Got it." Dipper said. "And hey, sorry again for nearly letting Timely get away with it. You're right. I'm supposed to be the smart one. I should have known better than to use time travel for something as stupid as a crush."

"You're not stupid, Dipper. You're just young. We were all that way once." Mobius said. "And hey, if it makes you feel any better…" He pulled Dipper in to whisper into his ear. "Wendy and Robbie are not endgame." That brought a smile to Dipper's face.

Mobius picked himself up and gestured a goodbye to the kids as he walked away with the rest of the TVA agents. They passed by the dunking booth where Stan was.

"Ha, you suckers! Your pockets are empty and I'm still sitting high and dry!" Stan taunted to everyone who failed to dunk him. They all booed at him, but he took it proudly. He then noticed the TVA agents and decided to have a shot at them too. "Hey, you! Stormtroopers! I'm talking to you, haircut! Take your best shot!"

One of the agents took Stan up on his challenge and fired a laser at the target. It was destroyed and Stan fell into the water earning the cheers of the crowd.

Kamala treated Dipper and Mabel to question-mark-shaped corndogs and walked with them across the fair. They stopped when they noticed Wendy and Robbie hanging out over a caramel apple.

"Geez. I gotta deal with this all summer?" Dipper asked in an annoyed tone.

"If at least one bad thing happens to Robbie, at least this won't be a total waste." Kamala said.

"I might just help with that." Mabel said. She patted Waddles twice and let him do his thing.

Waddles sniffed the air until he caught a whiff of Robbie's caramel apple. He squealed loudly as he made a mad dash for it. Robbie saw Waddles coming and freaked out. He ran away from him dropping his caramel apple for the pig to eat. Robbie stopped, but he accidently knocked over a large vat of hot water over his tight pants, which shrunk painfully over his legs.

As Robbie fell, everyone around him saw his predicament and laughed. Even Wendy couldn't stop herself from laughing. Stan also laughed from inside of his water tank.

After laughing, Dipper looked affectionately at Waddles and sighed happily. "That'll do, pig. That'll do."
