Avery sat on the bench during lunch at school, listening to a song by an obscure artist. She watched students go by, occasionally removing the right ear bud to see if anyone would stop to talk to her. As per usual, no one would, so she placed it back in. Today was a special day, her birthday. The school had announced that it was her birthday, along with four other students. Those who knew her would give her a casual "Happy birthday" but then they'd walk along, ignoring Avery's call of thanks.

She felt no one liked her, which wasn't entirely true. Some thought she was mentally insane, though she was clearly not, and avoided her at all costs. Others wanted to be her friend, but she had not recognized their advances, and consequently, their attempts always failed. Avery hated that she pushed people away. She hated herself for losing control of her depression in freshman year. She hated everything about herself, from her freckled face to her large thighs.

The bell rang, signaling that lunch was over. Avery stood and threw away her sandwich that she had stopped eating about halfway through the lunch period. She walked to her locker, and reached for the lock. As she began to turn the combination, she noticed that people were crowding around her locker with various expressions. Some looked shocked, others confused, others were grinning. Avery finally looked up and saw a note taped to the door near her number. It was a torn scrap of yellowed paper held up by scotch tape.

I'll see you at home, Avery! Good luck until then!

"Hey!" Someone called out to the rest. "Someone's got a crush on the crazy girl!"

"And they know where she lives!" Someone else cried. "She's got a stalker!" As the crowd dispersed, Avery swore she heard someone say: "I hope they kill her." She took off the note and stared at it for a minute. The handwriting was odd. No one she knew had that kind of handwriting. Who wrote this? Did she really have a stalker?

She folded the note neatly into a square and stuffed it in the pocket of her jacket, intending to throw it away after she could observe it better. She hurriedly got her things, re-locked her locker and left for her history class.

Avery sat in the back of the class, where her assigned seat was. Everyone had been given an assignment to work on with a partner, and since someone was sick that day, Avery was left to be the odd one out. She finished typing the last slide of a presentation in the Google Drive and viewed the presentation. Everything looked fine. She sent it to her teacher, who told her that she had received it a few minutes afterwards.

She took out the note again, trying to figure out who wrote it and why. She stared at it, comparing the handwriting to those of her classmates. She had helped the teacher grade a few tests from time to time for extra credit, so she was somewhat acquainted to the handwriting. It wasn't Jimmy's. It wasn't Katie's. It certainly wasn't Paul's. She looked at it again. It looked to be made by a male, so that ruled out the girls. For the most part at least.

She noticed that her thumb was covering something, so she moved it aside. The image was that of a triangle with a pyramid design and a singular eye. Who the frick decided it was a good idea to send me the Illuminati? She noticed the triangle had a top hat, bowtie, and stick arms and legs, as though someone had doodled over it. Weird. "Whatever…" She sighed, tearing the note in half and tossed it in the nearby trashcan.

The class ended soon after. Avery began to head to her next class when she was stopped by a boy in her Honors Biology class. "Hey. You're Avery, right?" He asked.

"Yeah?" Avery tilted her head to the side slightly. Who was this boy? Oh, right, his name was Ruben…

"I heard about what happened at your locker." Ruben said. "Do you still have the note?"

"No, sorry." Avery shook her head. "I threw it away."

"Oh, okay." Ruben nodded in understanding. "Sorry. I just wanted to look at it. Do you remember what it said?"

"Something about seeing me when I got home." Avery shrugged. "There's was this weird triangle, too. The freshmen were probably playing a joke on me, huh?"

"Probably." Ruben smiled. "Gotta go. See you!"

"Bye." Avery waved, continuing to her next class.

As the day ended, Avery returned to find another note on her locker. She quickly tore it down, not wanting anyone else to see.

Don't tear my notes!

"Can't tell me what to do, mysterious note-giver." Avery smirked at her joke, but decided to keep this one anyways. She folded it again and placed it in her pocket once more. Looking around to see if anyone noticed, she got the supplies for her homework and locked the locker for the last time that day.

Avery closed the front door to her home and greeted the emptiness. Her parents wouldn't be home until at least six. She dropped her backpack near the coffee table in the living room and poured herself a glass of Coca-Cola. She was about to pick up the soda for a drink, but saw something move out of the corner of her eye. It had been quick, but she knew it had been there. Avery quietly picked up a kitchen knife from the knife holder and slowly walked to where she had seen the thing. She pressed herself against the wall as she heard someone speaking. Her grip tightened and she swung at the thing when she turned the corner. It hit nothing.

Avery straightened herself and called out. "Hey, dickbutt!" She yelled to the air. "I saw you! Come out, damnit!" She heard laughter behind her. Turning around, there was nothing again. "Come on! Stop screwing around!" Nothing responded this time. Avery sighed, after waiting for a few minutes, and returned the knife to the holder. "Whatever. My meds are probably going out of whack again…" She took her bag and went to her room to do her homework.

When she looked at the clock, Avery saw that it was six-thirty and that her parents had not yet returned home. Figuring that they were probably working late, Avery got up to get something to eat. A sandwich or a leftover pancake probably.

When she returned with a thick slice of ham she hadn't bothered to heat up, she saw her computer had gone dark. Despite her figuring it had gone to the screensaver, it wouldn't respond when she moved the mouse. The light indicating that the monitor was on was flashing. It did not flash for a minute and Avery saw a single file in the midst of the dark screen.

An executable file? What was this, a creepypasta? She sighed, since her other option to turn off the computer wasn't working, and clicked the file. The file opened an image of a cartoon-styled building. It had large orange letters reading "Mystery Hack" with an 'S' dangling near the 'H'. The building was close to wherever she was viewing it from. A door opened and a young girl followed by a young boy walked out. The boy was reading from a book with a six-fingered hand on the cover. The hand held the number three on its palm. The girl was saying something inaudible to Avery, while the boy was nodding in response. The girl faced the screen and stopped walking. She grabbed the sleeve of the boy's shirt and pointed ahead of them at Avery. She said something, her words still inaudible. The boy finally looked up and jumped back, startled.

Avery watched the two children with a confused expression. "What the frick?" She said aloud. The two on the screen stopped whatever they were doing and looked back at Avery. The boy walked over and Avery heard a tapping noise from the screen as the boy tapped on it. Avery blinked at the sudden sound. The boy took a step back. He began saying something. Avery realized they could hear her, but she couldn't hear them. She held up her index finger, signaling for them to wait. They seemed to understand.

Avery saw that her speakers were off, and went to turn them on. "Huh. They were on before…" She said in curiosity.

"What was on before?" She heard a girl's voice from the speakers.

"Oh my dear God!" Avery yelped putting her arms in front of her chest in a criss-cross manner. "What the actual frick?" She slowly walked back to the screen to see the children looking at her concerned.

"Are you alright?" The boy asked.

"Who the freaka-frack are you two?" She demanded. "Why are you in my computer? How can you see me?"

"Computer?" The girl walked over and tapped the screen again. "Is that what this floating screen is?"

"Floating screen?" Avery asked, slowly uncrossing her arms. "Is that what my monitor looks like from inside it?"

"Who are you?" The boy asked, walking to stand by the girl.

"I'm Avery." Avery said. "Avery Bravo."

"Nice to meet you, Avery!" The girl cheered happily. "I'm Mabel Pines! That's my brother Dipper!"

"Hello." Avery nodded.

"Hey, Avery?" The boy, Dipper spoke up timidly.

"Yeah?" She asked. "What's up?"

"Can you try… reaching your hand out?" he asked, as if Avery would think he's crazy.

"Like, to the screen?" Dipper nodded. "Alrighty. Here's goes nothing…" Avery slowly stretched out her hand and gently pressed against the screen. She screamed in surprise when her hand went through. She couldn't see it on the other side, but apparently Dipper and Mabel could.

"Pull her in!" Mabel cried suddenly. Avery felt a grip on her hidden wrist.

"Wait, what?" Avery yelled as she was pulled into the monitor. She grunted as she landed on grass. She looked up and screamed again.

She was in the cartoon world, with Dipper and Mabel staring down at her.
