Hi guys, nightmare here with a new story. I tried writing a one-shot series for Gravity Falls a while back, but I've stopped for…well for a number of reasons. Anyway, this is rated for a list of reasons, expect character bashing, death, lemons, a few things being changed around from the show and other things. So…nothing outside of…enjoy the first chapter.

Mabel Pine, 17-year-old twin sister to Dipper Pine, poked her head in her brother's room and saw him packing a suitcase, a hardened look crossing his face, "Hey bro-bro…what are you doing? Going on a trip or-"

"I'm…going back to Gravity Falls," Dipper sighed and shook his head before looking back with slightly narrowed eyes, "I already talked to mom and dad, they talked to Grunkle Stan and he's agreed to let me live with him,"

"So…what about school? You can't-"

"I have something to take care of back in Gravity Falls, Mabel, and it's a bit more important than school, and like I said, I've cleared it with mom and dad." Mabel frowned and Dipper sighed again, "Mabel, I need to…there's something in Gravity Falls I need to take care of, that's all I can say,"

He turned back around and continued packing his suitcase, "So…this is the end of our team?" Dipper stopped and Mabel stepped closer to him, "You're going to forget about me and go live with Grunkle Stan for what reason? Don't you love me, Dipper?"

"Of course I do, Mabel, you're my twin sister and my best friend," Dipper looked back and Mabel frowned, "Mabel…why don't you go talk to mom and dad and see if you can't come with me? Like I said, I have a reason to go, but you really don't have a reason to stay if I'm not here," Mabel's frown formed into a smile before she nodded, turned and walked out of the room. Dipper sighed before he felt his phone vibrate.

Looking down, he read the text, "When will you be leaving?" Dipper took a deep breath as his phone vibrated again, "I'm sorry if I'm annoying you, Pine, but this is more important than some stupid journal,"

Dipper rolled his eyes before running his thumbs across his phone, "My parents are taking me to the airport in an hour…and…Mabel might be coming with me." Sending the message, he frowned before his phone vibrated almost instantly, "What? Why is she coming? And how does she expect to get a ticket on a same day flight? That's almost impossible,"

Taking a deep breath, Dipper shook his head before replying, "It is possible, our parents are just going to have to pay full price for the ticket…I doubt they'll let her go, but we have seen stranger things, right?" sending the message, he waited several moments before his phone vibrated once again, "That is true…she doesn't know why you're coming, does she?"

"No, I just told her I have something to take care of and left it at that," setting his phone down, he continued packing his suitcase.

The twins sat on the plane while Mabel widely smiled, "This is so exciting, Dipper. We're going to see Grunkle Stan, and all our friends again," Dipper hummed, crossed his arms and leaned back on the chair, "So…why are you going back to Gravity Falls?" Dipper ignored his twin and Mabel slightly frowned, "Dipper, what is this important thing you have to-"

"Mabel, no offense, but we're going to be on this plane for like five hours before reaching Oregon, and right now, I have a lot on my mind and talking about it isn't going to help."

"O…kay? But if it has you so worried that you'll abandon Senior Year of High School, it has to be big," Dipper sighed and looked out the window, a hardened look crossing his face, "We could play twenty questions until I get it. Person, place or-"

"Mabel, what did I just get done saying?" Dipper looked back at his sister and took a deep breath, "I'll tell you when I clear my head. Right now…I just want to enjoy the plane ride, and not worry about what's waiting for me in Gravity Falls just yet." Mabel took a deep breath before she slightly nodded and leaned back on the chair.

Okay, so…the first two chapters are going to be…a tad slow. But after that it'll start going, so…please be patient during these first few chapters and then things will start moving. As always enjoy everyone and please let me know what you all think.
