Standard I don't own Gravity Falls or Life is Strange and/or their characters and all that legal stuff…

Author's Note: This is a story which takes place the summer before the events of Five Years Later: A Star Falls. It's the party that Wendy and Dipper reference over drinks at the Mystery Shack. I also decided to have some other Oregon characters stop by for a bit of a crossover since I always thought they existed in the same universe.

Underage Discoveries On A Reckless Night

Chapter 1

It was the second week in June in the small Northern Oregon town of Gravity Falls. As had been tradition for the previous three years, Dipper and Mabel Pines had returned from Piedmont, California to spend their summer vacation in their adopted home away from home. Mabel was now fifteen years old and looking forward to a summer of romance and her sweet sixteen at the conclusion of it. She had grown taller than when she had first set eyes on Gravity Falls that first fateful summer. Long chestnut hair cascaded down her back. Gone were her braces, much to her relief. She sported her trademark pink sweater, adorned with a shooting star. A pair of skinny blue jeans covered her long, slender legs, save for the tears near her knees. Pink sneakers completed her casual, albeit unique ensemble.

Dipper Pines had been looking forward to the trip almost since the day he had left last August. Although he did have friends back in California, he felt more at home in the forests of the Pacific Northwest. The teen boy had grown a bit as well, about five and a half feet tall, but still shorter than his sister. His brown hair had remained as messy as ever, but for some reason the girls in Piedmont seemed to like it now. He wore a plain grey tee shirt, which was covered by an unbuttoned red plaid long sleeved shirt. Dark blue jeans and black track shoes completed the fifteen year old's look.

Dipper and Mabel couldn't wait until they could drive to the town next year, as the bus was getting old. Every year since Wierdmageddon, more and more tourists had flocked to the town due to the rumors of a supernatural war occurring there. Business had never been better for the Mystery Shack, much to the pleasure of Stanley Pines. The older man had been able to afford trips with his twin brother to seek out more legitimate attractions for his tourist trap, which he had convinced his brother was purely in the name of science and not profit. While the Grunkles were gone for long stretches of time, Soos would run the Mystery Shack. He was joined in the off season by his wife Melody, longtime friend and co-worker Wendy Corduroy and newcomer Pacifica Northwest, who welcomed the after school job as an escape from her overbearing parents.

The Pines twins had arrived back in Gravity falls at around two in the afternoon. From the bus stop the two teenagers walked up the long dirt road that lead to the Mystery Shack. After a short hike, they arrived at the wooden A-framed building. There were only a few cars in the parking lot, which Mabel and Dipper were grateful for, as they did not want to get straight to work on their first day. "It's good to be back!" the brunette teen girl exclaimed to her brother. "Yeah, I really missed the old place" he replied. The twins ascended the creaky steps that led to the front door of the building. Dipper looked through the stained glass of the door to see a few shadowy figures moving about. Dipper placed their bags and suitcases on the front porch while Mabel grasped the door knob and turned, opening it.

Wendy sat at the register, as Pacifica dusted some of the overpriced trinkets on a shelf. A bell placed above the door rung as the door suddenly opened. "Welcome to the Mystery Shack, where Mystery is all arou…" Wendy half-heartedly began to say the line she had rehearsed for years, all the while her head remained buried in a magazine. The auburn haired teen looked up and saw a familiar and welcomed sight. It was Mabel and Dipper. "Dudes, you're here!" Wendy exclaimed as she yanked her feet off of the check stand and stood up. Pacifica turned around and a smile came across the blonde teens face. Wendy and Pacifica rushed towards the twins. Both teen girls wrapped their arms around Dipper and Mabel. "Guys! We missed you so much!" Pacifica practically squealed. "Yeah, it wasn't the same without you two" Wendy said as she squeezed the twins with all her might . "We missed you too!" Mabel excitedly proclaimed to her friends.

Mabel and the teen girls walked over towards the checkout stand as Dipper exited the building to gather the twins' luggage. "Always stuck with doing the hard work…" the teen boy muttered to himself as he struggled to both carry the luggage and open the door at the same time. "Let me help you out with that dude!" a familiar voice called out from the parking lot. It was the new Mr. Mystery himself, Soos. The once large man had slimmed down a bit, but his personality was as large as ever. "Thanks man… it's good to see you" the grateful boy said to his good friend. "No problem. You should have called dawg. I could have gotten home a little quicker and helped you guys out" the always helpful former handyman said to the brown haired teenager. "Well, we didn't want to make a fuss, so we decided to surprise you guys" Dipper explained. Soos picked up some suitcases as Dipper opened the door. "THANKS FOR THE HELP SOOS!" the frustrated teen boy passive aggressively called out to his twin sister. The brunette teen girl turned around and realized that she had forgotten to assist her brother with the luggage. "Dip, I'm sorry. I completely forgot. Let me help you with that" Mabel offered. "It's fine, I've got it now" the teen boy said to his sister. "Me and the girls were just catching up. I really wanted to help" the teen girl tried to convince her clearly angered brother. Dipper looked up with an angry expression at his sister, but then took a deep breath and smiled. "It's okay, I get it… Plus, I could have asked again before trying to tackle it all by myself…" the teen boy relented.

The front door of the Mystery Shack opened yet again. "Welcome to the Mystery Shack, where mystery is all around you!" an excited Mabel called out to two twenty something girls. Dipper turned and was struck by the appearance of the women. The first was a slender woman with shorter blue and purple hair, her head covered by a dark blue beanie. She wore an extremely low cut white tank top emblazoned with a skull on it, which was partially covered by a black jacket. The mysterious woman had the sleeves of her jacket pushed up, revealing a very colorful tattoo on her arm. Patched up and worn grey skinny jeans adorned her legs, with suspenders dangling unused behind. A very scuffed up pair of combat boots completed this unique woman's look. The second woman to enter had a much more normal ensemble. She was shorter than her friend, with a sandy brown bob as her hairstyle. The girl's slender body was adorned by a salmon pink tee shirt with a deer on it and a heather grey hoodie. Skinny blue jeans with tears in the knees covered her legs and black skater shoes completed her look.

The two twenty somethings walked over to Wendy, who was still chatting away with Pacifica near the checkout stand. "Corduroy, what's up?" the blue haired woman asked. "Hey Chloe, nothing much, just working…" the auburn haired teen replied. "Hey Max!" said Pacifica to the sandy haired woman. "Hey Pacifica…" she replied. "So… I got word that you're friend Tambry is throwing a sick party tonight… mind if we crash it?" Chloe inquired. "Well… it was kinda just gonna be a little get together since our friends just got to town for the summer… not really a bash or anything… but sure… you and Max can come…" the redhead hesitantly said to her older friend. "Cool… so who are your friends… because if anyone's a friend of yours, they're a friend of mine… ain't that right Max?" the blue haired woman asked her companion. "Yeah…" Max replied as she nodded her head. "Hey, Dipper and Mabel, can you come over here?" asked Wendy. The twins walked over to the group of women. "These are my friends, Dipper and Mabel Pines… aka the Mystery Twins… Mabel and Dipper, these are my friends Max Caulfield and Chloe Price, aka the life of the party" the auburn haired woman introduced the two pairs of her friends to one another.

"Hey, nice to meet you!" Mabel exclaimed as she waved to the women. "Hey, I'm Di-dipper…" the teen boy stumbled over his name as a mildly annoyed Pacifica stared on. "I think somebody has a crush!" Mabel yelled out as Dipper's face turned red and he stared at the worn wooden floor. Max and Chloe noticed the awkwardness of the situation and looked over at Mabel. "Not cool…" said Wendy in a somewhat unusually stern tone as she walked over to the clearly embarrassed teen boy. "Sorry… I was just kidding…" Mabel said apologetically as she began to wonder if she had done anything right since stepping foot town. Chloe put a hand on the brown haired boy's shoulder and picked his chin up with her hand. "Hey… it's cool. You're not too bad looking yourself…" she said, trying to cheer him up. Pacifica, who harbored a crush on the teenager was about to step in and say something, when Wendy shot her a knowing look. The redhead walked over and whispered into the blonde haired teen's ear. "Max and Chloe aren't interested in Dipper, if that's what you're worried about…" Wendy reassured her friend. Max put a hand on Dipper's back. "Too bad she's already taken… right Chloe?" the sandy haired woman said. "Yeah… but hey… I mean, there's gotta be a few girls out there thinking of you… I mean who knows dude; there could be a chick right here that is hella crushing on you… "Chloe said as she looked around the room. "Yeah…" Dipper said as he regained his composure. Max walked over and gave Chloe a slight peck on her partner's red lips. Pacifica had a momentary look of shock on her face, which quickly changed to a more calm and relaxed expression as she had understood what Wendy had meant.

"Sorry man, but she's all mine… so it looks like you're shit outta luck…" Max said as she lightly jabbed him in the side. "Okay… break it up you two… I know I'm by far the fairest maiden in this room, but don't fight over me!" Chloe facetiously exclaimed. Wendy, Pacifica, and Mabel laughed at Chloe's fake concern. "Well… we gotta go, but we'll for sure be at the party tonight…" Chloe said to Wendy. "Okay, see you guys there" the auburn haired teen replied as the couple left the Mystery Shack. "Well… it's five o' clock, so I'm outta here" Pacifica said as she headed towards the door. "You're coming to the party tonight, right?" asked Wendy to the blonde girl. "Yeah… I wouldn't miss a party with you guys…" Pacifica responded as she left the Shack as well.

Dipper had walked to the kitchen to grab a bite to eat. Mabel was about to follow her twin brother when Wendy grabbed her by the arm and pulled the brunette teenager aside. "What the hell was that?" asked the somewhat angry redhead. "I was just messing around… I know that Dipper likes Pacifica… and that she likes him back… I was just trying to show her that he's not going to just wait for her to say something… I mean, I think I have friends back home that are just my friends so they can be close to Dipper… I really want them to end up together, but one of them has gotta make a move" the somewhat upset teen girl said as tears began to fill her eyes. "Mabes… I get where you are coming from… I do… but what you did was a major violation of girl code…" Wendy explained to her friend. "I was just trying to help… I'm really sorry…" the teen girl said staring at the wooden and dust covered floor of the gift shop as a few tears began to run down her face. Wendy got down on one knee and lifted Mabel's chin up with her hand. She gave the brunette teen girl a small peck on the cheek and looked her straight in the eyes. "Mabel… you have an unbelievably big heart and I know you just want the best, but sometimes when it comes to love, you just have to let it naturally play out" she said as the teenager wiped the tears off her cheeks. "Thanks Wendy. You always know just what to say" the younger girl said to her good friend. Dipper entered the room with a plate in his hand. On it was a sandwich, some chips and a pickle. "I think your sister has something to say…" the auburn haired teenager said to her friend. "I'm sorry bro. It was wrong of me to call you out like that and I'm really sorry" the brunette said to her twin brother. "It was a jerky thing to do… but I guess since I clearly never had a shot with them… it's all good" Dipper said with a mouthful of sandwich. "Don't fill up too much dude, there's gonna be a ton of food at the party tonight…" Wendy advised her friend.
