"I'm bored!" Mabel lightly kicked Dipper's leg. "We should do something!"

Dipper sighed and looked up from his paper. He currently had a stack of papers sitting next to him. Bree sat on the other side of the papers, reading her own. The two were grading the class's first assignment from Ford. Everyone was supposed to write their own theories about the weirdness and why it centralized around Gravity Falls. Then they were supposed to explain why they believed that the weirdness was supposed to be here. Ford was supposed to have read them himself, but he had a meeting with a couple of the other professors so he had asked Dipper and Bree to summarize for him. "Mabel."

"I know!" She jumped up. "We should have a party this weekend! Our first college party!"

"Mabel we don't even have time to plan it." Dipper shook his head but stopped as Mabel glared at him. "What?"

"Like it would take me that long to plan a party."

"We don't even have a spot to have it. And we are not having the party in our apartment." Dipper set down his current paper.

"I could take care of that." Bree set her own paper down.

"Bree." Dipper frowned.

She smiled. "Come on Dipper. A little Chaos is good." Both Dipper and Mabel looked at Bree in confusion. Chaos was not their favorite word. Bree rolled her eyes. "A little controlled chaos is all you need for a party. A party without chaos is boring."

Mabel smiled. "Right!" She grinned. "I like you Bree."

Bree chuckled. "Give me a moment and I'll get us a place… Do we want it tonight?"

"Yeah!" Mabel grinned and pulled out her phone. "I'll get the info out!"

Bree nodded and pulled out her own phone and typed in a few things and then held it up to her ear. She waited a moment and then smiled. "Hey Grandma…. No I'm doing good…. Yeah no problem… Hey listen I was wondering if I could borrow the keys for the gym tonight…. We're throwing a party… Yeah I'll keep an eye on it… No problem… Thanks I'll swing by and grab them. Thanks. Love you." She hung up. "We're good. The gym is ours."

"Great!" Mabel grinned.

"Wait your grandma will just give you the key to the gym?"

"Yeah." Bree smiled. "I'm my Grandma's favorite so she basically will do whatever I ask… Well short of anything illegal." She chuckled. "I tried once as an april fools day joke and she laughed."

"That's awesome!" Mabel was grinned and practically jumping up and down.

"What about decorations?" Dipper sighed.

"Already on it." Bree grinned. "We keep a bunch of stuff in storage. Mabel and I will take care of that."

"Come on Dipper!" Mabel begged. "We're in college now!"

Dipper looked from Bree to Mabel to Bree to Mabel and sighed. "Fine. I'll come if you get it set up."

"Great." Bree set down her pen. "Then you wouldn't mind doing the rest of the summarizing. Thanks." She grabbed Mabel's arm and started to run off.

"He. Ah forget it." Dipper sighed and went back to summarizing.

⁂※⁂※⁂※⁂※⁂※⁂※

"Done." Mabel grinned as she looked over the gym. After an hour it was finally finished. "Not too bad if I say so myself."
Bree chuckled. "You really are the queen of quick parties."

"You have no ideas. We're just lucky your grandma had so much random supplies we were able to use. There was even a disco ball!" Mabel grinned as she looked over the gym again. Bree had led Mabel to a closet full of junk and Mabel had pulled out everything that they could use. There was a couple mirrors that would catch the disco ball lights and there was plenty of colorful streamers. Mabel had cut up some old posters, with Bree's permission, to use as wall decorations.

"How long till the party?" Bree asked.

Mabel checked her phone. "We've got an hour and a half."

"Good I still have time to go get ready." Bree pocketed the keys. "I'll see you at the party then."

"Yeah. And feel free to invite all your friends." Bree just turned and walked away. Mabel turned and looked over the decorations and then walked in front of a mirror. "Not bad." She looked at herself. "This is college party ready." Mabel wore an embroidered pink frilly tank top blouse and a cute pair of jean shorts that she had bedazzled.

"Yeah not bad."

Mabel glanced around her but no one was there. "Who said that?" She looked around but turned back to the mirror as she heard a whistle. Standing in the mirror was a mirror image of Mabel, only this one was smirking and waving her hands.

"Hi there." The image said.

"You…" The mirror's surface seemed to ripple and then hands reached out and then Mabel was pulled into the mirror. She crashed and groaned. Standing over her was the mirror image.

"Thanks Mab." Mirror Mabel smirked. "I've been bored in here for ages!" She spun. "And now I'm free."

"Who are you?" Mabel stood up and realized that the mirror Mabel was standing on the other side of the glass.

"I'm the mirror shadow of you. But from this point on I'm Mabel Pines. Freshman student at Gravity Falls College… And maybe some day I'll come back to tell you how wonderful your life has gone." The mirror shadow waved a hand and then walked off.

"NO!" Mabel yelled and banged on the glass surface, but it wouldn't break. "Dipper.. Please help."

⸙‽⸙‽⸙‽⸙‽⸙‽⸙‽⸙‽⸙‽⸙‽⸙‽

Dipper tugged on his hat and looked in the mirror. Then he took it off. But that just didn't feel right. He sighed and put the hat back on. "I look fine."

"Hey Dip!" He spun to see Mabel watching him. "Lose the hat."

"Mabel?"

"Come on! It's a party!" Mabel grinned and walked over to him. She took the hat off and tossed it onto the bed and ruffled his hair. "Loosen up brother." She spun. "Now come on or we'll be late!" She turned and ran out the door.

Dipper sighed but turned and followed her, locking the door behind him. It didn't take long to reach the gym and it was already full of people. He noticed Pacifica talking with a group of boys. She looked over and waved at him. Dipper smiled and waved back. "Hey Mab-." He stopped as he spotted her running over to the dance floor. She grabbed a guy and the two started dancing. "That's weird." He whispered. But he shrugged and headed over to talk to a couple people he knew.

Dipper didn't see Mabel again for an hour, and when she did it was just for a second while she grabbed a drink of punch and then ran back out to the dance floor.

"What's up with Mabel?" Dipper turned to see Wendy.

"What do you mean?" Dipper glanced back out at Mabel, who was dancing in the middle of the floor. She seemed to be trying to be the spotlight of the party. That did seem a little odd.

"I just passed Grenda and Candy and both of them hadn't even talked to Mabel once." Wendy frowned. "Plus when has Mabel danced with a bunch of different boys without even getting their names?"

"What do you mean?" Dipper frowned.

"She danced with Jake and didn't even ask his name." She looked over at a tall boy with brown hair. "Not to mention that fact that she didn't even let him say no. She was… aggressive."

"And Jake is?"

"My new boyfriend." Wendy said. "Which I told Mabel when we talked earlier… It's strange that she choose to dance with him as well."

"That does sounds odd." Dipper watched his sister. Something about her was off, he just couldn't figure it out. "I'll talk to her."

"Thanks Dipper." Wendy smiled and walked back over to her boyfriend.

Dipper shrugged and headed over to Mabel. "Hey Mabel!" He called over. "Mabel."

"What?" She didn't stop dancing as she spoke. "Dipper I'm dancing right now! We can talk after the party!" She smiled. "I'm dancing with Theo."

"Thomas!" The man across from her called.

"Yeah that." Mabel laughed.

Mabel frowned and walked off the dance floor. He spotted Bree standing at the punch table by herself. She wore a light blue frilly blouse covered by a navy blue jean jacket. She was fiddling with the golden chain around her neck. "Hey Bree!" he walked over to her. "Was Mabel acting weird while you were decorating?"

"No." Bree took a drink of the punch. "She was acting normal.. Well as far as I'm aware. Is she normally that… happy?"

"Yeah." Dipper glanced out at the dance floor. "But Mabel's been acting weird since she got back."

Bree looked out at the dance floor. "She seems-." She stopped. "It's not normal for Mabel to ignore people is it?"

Dipper glanced over where Mabel was ignoring Pacifica. "No… Something is wrong with Mabel." He frowned. "Come on." He grabbed Bree's arm and dragged her out of the gym.

"Where are we going?" Bree asked following.

"To get back up." Dipper stopped and pulled out his phone. He typed in a number and waited. It rang a few times and then Ford picked up.

"Dipper?"

"Ford?!" Bree hissed covering the microphone. "Why Ford?"

"We need his help." Dipper frowned.

"Blowing up the gym?" Bree frowned. "We don't need him!" She glared at the phone.

Dipper frowned. "He's the only one who might know what is going on. I sure don't do you?" Bree frowned at him but pulled her hand away from the phone. "Grunkle Ford Mabel is acting weird. How long till you can reach the gym?"

"I'll be there in a few." Ford sounded intrigued.

"Thanks." Dipper hung up and looked at Bree. "What is your problem with Grunkle Ford? I know he's a little destructive sometimes."

"Sometimes?" Bree rolled her eyes. "You have no idea how many times my grandma has called and complained to me about Ford. Half the time she calls me it starts with 'Ford this' or 'Ford that.' Once she told me Ford blew up a classroom."

Dipper sighed. "We need his help though."

Bree sighed. "Fine. But if he destroys anything then you take the blame." She looked away. "Stupid Pines…"

Dipper rolled his eyes but the two waited until Ford came walking up. "Dipper what is going on?"

"Mabel has been acting odd since she finished setting up for the party. She's ignoring her friends and can't remember people's names."

"Well maybe she's just a little overwhelmed." Ford frowned.

"She's taking over the spotlight." Dipper frowned.

Ford froze. "Are you sure?... How long has Mabel been acting like this?" He glanced towards the gym.

"Since we finished setting up." Bree said. "But listen Ford… If we let you help there is no destroying, blowing up, or breaking things." Bree folded her arms over her chest. "Agree?"

"I see you have been talking to your grandmother again." Ford chuckled.

"Just agree." Bree frowned.

"Very well." Ford chuckled. "Now let's go." He opened the door and the three of them walked in. Ford glanced around and frowned. "Bree… where did you get those mirrors?"

"Huh?" Bree glanced over at the mirrors set up around the room. "They were shoved in a closet. I think a science teacher used them once for a light experiment."

"I wonder…" Ford frowned.

"What is it?" Dipper asked.

"Bree, Dipper see if you can examine those mirrors. See if there is any strange symbols on the frames."

Dipper and Bree nodded and hurried towards the closest mirror. He glanced towards Mabel, who didn't even seem to realize Ford had shown up, and then back at the mirror. It looked normal to him and nothing seemed odd. He turned and headed towards the next one. He eyed it over and then froze. He could have sworn he just heard Mabel's voice. He looked over his shoulder. Mabel as still dancing.

"Dipper!"

He turned and found Mabel standing in the mirror. She was banging on the glass. "Mabel?!"

"Dipper you have to help me!" Her voice sounded muffled.

"What happened to you… Hang on!" Dipper turned and ran over to find Ford and Bree. "I found the mirror!" Dipper said. Flip it around

"Right then." Ford said. "Which one?" Dipper pointed. "Okay. Now then we need to get the mirror as far from Mabel as possible." He glanced at Bree. "We will probably have to destroy it."

She frowned. "And why is that?"

"The spell on the mirror causes those who look into it to act darker. As long as the mirror is near that person they will-."

"Um Grunkle Ford." Dipper interrupted. "I don't think that is the problem."

"What?" Ford asked.

"Mabel is trapped in the mirror." Dipper said and then looked back at the fake Mabel.

"Mirror shadow!" Ford grinned. "Never thought I would see one of those again!" He smirked. "New plan. We need to get Mabel, the fake Mabel to stand close enough to the mirror for us to push her in."

"No breaking?" Bree folded her arms.

"As long as we keep the mirror covered I guess we don't have to break it." Ford shrugged. "Actually I would like to examine the mirror myself so I would prefer we not break it."

"Good." Bree smiled. "Then I'm on board." She looked at the fake Mabel. "You two get ready to push her, I'll get her over there. Bree turned and headed out onto the dance floor.

"That Bree." Ford sighed. "She's sure a stick in the mud." He lightly pushed on Dipper's shoulder and smiled.

"Is it true you blew up a classroom?" Dipper looked at Ford and raised his eyebrow.

Ford chuckled. "Oh yes I remember that time. We had an accident with a bunsen burner and an annoying little trickster fairy."

Dipper sighed. "I can see why Bree and her grandma don't like you."

Ford shrugged. The two of them threaded their way to stand behind the mirror. They watched as the fake Mabel followed Bree over to a cut out on the wall near the mirror. Dipper could hear them talking.

"Mabel I showed my grandma the cut outs you made and she really liked them. She wanted to know if you would help out with some decorations for the school's next event. We're on a budget and we could use your creativity."

"Sounds great." The fake Mabel smirked. "But I would prefer if I could get paid some for it. My time is pretty busy."

"Yeah no problem." Bree smiled. She started walking again, but this time she was walking towards the mirror. "Come take a look at some of these supplies and tell me Now!" Bree yelled this as the fake Mabel walked in front of the mirror.

Dipper and Ford shot forwards and grabbed the fake Mabel's arms. She started to struggle but the two of them were stronger than her. "Ready Dipper?" Ford asked. Dipper just nodded and the two of them tossed the fake Mabel into the mirror. A moment later Mabel came stumbling out.

"Mabel?" Dipper asked cautiously.

"DIPPER!" Mabel flung her arms around his neck. "Thank you!" She let go and hugged Ford. "Thank you Grunkle Ford!"

"Let's cover this up." Bree said walking over and throwing her jacket over the mirror. "Let's not have any mirror shadows walking around."

Ford chuckled. "I'll come pick the mirror up later and take it to my lab to examine."

"Maybe you should get it now." Dipper looked at it. "I'll help you."

"Thank you Dipper." Ford nodded. "And thank you Bree." He smiled. "I promise I'll try not to break this one."

Bree shrugged. "Yeah Yeah." She turned and started to walk off. "Just don't let that mirror shadow out either."

"No problem." Dipper called after her.

"I think I'm growing on her." Ford laughed.

Dipper just shook his head and helped lift the mirror. He watched as Mabel ran over to Candy and Gretel. It's good to have her back.
