Hey, DeathStricken back! I'm here to bring you a Gravity Falls AU fanfic! Now, this AU that I am writing, is similar to an AU called Reunion Falls, but I'm changing it in a few ways. Trans! Dipper, while he is sort implied in reunion falls, is going to have a bigger role here. I'd like to show his transition and how everyone handles it. Also, here, Dipper is the one who finds the journal. He's cold to Mabel at first, warming up to her as soon as he comes to find out that they're related. He doesn't want to admit it, but he quickly realizes how much he needed Mabel in his life. So, sit back, and enjoy the story.

"Morgan."

"Morgan."

"Morgan!"

Dipper's head snapped up. He looked around the room, eyes wide. He wiped the drool off the side of his mouth with the thumb.

"Please show our new student to her locker," the teacher at the front said, placing her hand on the shoulder of the girl beside her. "Morgan will show you to your locker."

Dipper rolled his eyes and stood up, grabbing his bag and tossing it over his shoulder. People stared at him, some turning to whisper and giggle to their friends, other giving him looks. He kept his head down, pulling his hat down as far down as he could. He grabbed the new girl by the sleeve of the sweater as he walked by. She stumbled after him, out of the classroom.

"So..." The girl behind him said. "Morgan huh?"

Dipper stopped walking and turned. "Don't call me that. It's not my name." He released her sweater and turned back. "My name is Dipper."

There was a brief silence between them before the girl spoke again. "Yeah, that looks much better on you. I'm Mabel." She jogged up to walk beside him. "So what's the story behind Dipper? Your parents like stars or something?"

Dipper shrugged. "I dunno. I've never met them."

Mabel frowned. "Oh."

He shoved his hands into the pockets of his vest and looked away. What was this girl's deal? Why did she care so much about him?

A few minutes of awkward walking later, they reached a row of dark green lockers, numbered off from 235 to 255. One of the lockers right in the middle had the word "queer" spray painted in messy black lettering. "This one's yours," he muttered, pointed to the locker beside the painted one. He fiddled with the lock on the painted one until it opened. "And...this one is mine."

He pulled a spray bottle and a cloth off of the top shelf. Then, closed the door and sprayed the door a few times, wiping it off with the towel. He was glad it was still freshly painted, or else that would've taken a lot of scrubbing.

Dipper tossed the bottle up top and grabbed a worn red book, shoving it into his bag. "You know how to get back to class right?" He asked flatly, looking over at Mabel as he locked the locker.

"Uh, yeah," she said, doing the same. "Aren't you coming too?"

"No, I'm going home. Don't bother covering for me or anything."

"Dipper, you're going to fail school if you keep doing this." His great-uncle sighed, looking down at him. "And pretty soon I'm gonna have to start telling Soos to stop picking you up."

Dipper sighed, sliding down the couch until his back was on the seat part. "My teacher hates me, Grunkle Stan. She made me show the new girl to her locker. Which with my luck is right beside mine. Ugh, what if she tries to talk to me again?"

Stan sat down beside his great-nephew on the couch. "Listen kid," he said. "People suck. You just gotta face 'em until you find one that doesn't suck. Maybe that new girl is one of 'em? Talk to her tomorrow, just see what happens."

Mabel Pines stood in front of the old-looking building. She held a worn red book in her hands. There was a sheet of paper neatly folded and placed inside. The sign on the door read closed, but she could see a girl sitting at the counter, reading.

Hesitantly, she knocked on the door. A tall girl in a green flannel with fiery red hair looked up from the magazine she was reading at the counter.

"Sorry, we're closed," she yelled from inside.

Mabel bit her lip. Come on, you can do this. "Uh, yeah, I know. Um, does Morgan live here?"

The red haired girl looked up at her immediately. She was up and at the door in seconds. When the door opened, she had a glare on her face as she looked at Mabel. "Who's asking?"

Mabel took an unintentional step back. "Uh, Mabel? He dropped his book, and I have his homework. I saw a Mystery Shack sticker on the truck he got picked up in." She held the book out in front of her. "And, it looks like it came from here, there's some pretty weird stuff in here."

The ginger looked down at her for a moment, then stepped back, opening the door. "Come in, I wanna talk to you about something." Mabel gulped, but followed her in anyway. "Oh, I'm Wendy by the way."

Wendy sat down back behind the counter and propped her feet up. Flecks of mud fell off her rubber boots. "Where'd you get the name Morgan from?" She asked.

Mabel tugged the sheet of paper out of the book and passed it over to Wendy. "That's what the teacher calls him. I don't know why. When I called him that, he got really defensive. I don't remember the name that he told me to use."

"Dipper," Wendy said, her eyes skimming over the homework page. "He didn't tell us that his teacher calls him Morgan." She frowned slightly and passed the paper back.

"Yeah, a lot of people do. And other, nastier things."

"Like what?"

Mabel thought for a moment. Well, she only saw him for a few minutes. "Well, someone painted the word queer on his locker. He seemed to be used to it, he had a spray bottle in his locker and everything. When I went back after class, it said fag, but I scrubbed it before it dried completely."

Wendy frowned at Mabel. She had a pain expression on her face, one that showed hurt. "I...wow, I just can't believe he never told any of us this. I'll talk to him." She stood up, walking back towards to door. Mabel followed after her, taking this as a sign that it was time to leave. She left the book on the counter for Wendy to return to its owner.

"Thanks for telling me what's goin' on," the ginger girl said, smiling slightly at Mabel. "You're really cool. Watch out for him for me, okay?" She pulled a hat off the shelf, one identical to Dipper's and pulled it backwards over Mabel's head. "Maybe he'll warm up to you."
