Four years have passed since the Pines twins first arrived in Gravity Falls, Oregon. Now as 16 year olds, the twins have done many things in this unique town that has left deep impressions on their lives. In the case of Mable, coming to this town has allowed her to become more independent as a teenage girl, and has helped her gain a close friendship with her two friends, Grenda and Candy. However, with regards to Dipper he was more excited than anything to see the girl of his dreams, Pacifica Northwest.

Four years ago at the beginning of that summer that changed everything, Dipper could not stand the sight of this blonde Northwest. She was selfish, rude, arrogant, and most of all mean to Mable. To Dipper, being mean to his sister meant that you would be placed on his mental "dead to me" list. But mid-way through that first summer, something changed. Dipper started to get to know Pacifica, and learned that behind all that bitterness Pacifica was a really sweet girl that just needed help. One could say it was at this point that Dipper started to get feelings for her right then and there. As the summer progressed the two spent more time together and learned to enjoy each other's company with mild flirting between the two. At the end of that first summer, Pacifica met Dipper at the bus stop to tell Dipper not only goodbye to but tell him about the feelings she has for him, give him her number, and kiss him for the first time.

Throughout the next four years, Dipper and Pacifica would keep in constant contact with each other through social media, and phone calls. It wasn't until the middle of the following summer that the two confessed their love for each other. The two couldn't leave each other alone, the whole town was happy to see the two of them together. That summer went so well that Pacifica's mother and father finally started to enjoy the company of Dipper and welcomed him to be a part of their family.

The Northwest's enjoyed Dipper's company, not only was their daughter happy, the Northwest's had someone new in the house to have fun with. At the end of that summer, Mr. Northwest gave Dipper a job offer at their company's Bay Area location. It was a small job, just cleaning the warehouse with a broom, but it allowed Dipper to steadily earn an income to save for college, and on occasion, buy gifts for Pacifica and mail them to her in Gravity Falls.

Both Pacifica and Dipper where born in the month of October so it was that fall in which Dipper could actually afford to get Pacifica exactly what she wanted for her 15th Birthday on October 9th. Pacifica cried with happiness, when she received her present from Dipper, a framed photograph of the two of them at 12 years old standing outside the Mystery Shack, holding hands. Pacifica in return felt that nothing she could buy him would capture the love that is being shown in that picture. Pacifica, along with help from Mable decided that she should fly down to San Jose and surprise Dipper at school. On Dipper's 15th birthday, October 25th, Pacifica Northwest walked into the large public High School to surprise her lover. She found Dipper, walking alone in the hallway between class periods, still wearing his one of a kind blue and white hat. Pacifica also noticed that three other students, wearing letterman jackets with football patches, walking behind Dipper planning to harass him. This infuriated Pacifica so much that she started to hustle down the hallway after Dipper and the three bullies. Shoving people out of the way to protect her man. Just as she got behind the bullies she overheard one saying,

"Hey guys, let take this loser's hat and flush it down the toilet."

The three bullies laughed, when another one piped up,

"Hey dude, we should piss all over it first just too absolutely ruin it for this loser."

This infuriated Pacifica, "No one, and I mean no one talks like that about my Dipper."

It was then that Dipper turned around, stopped dead in his tracks and saw the bullies.

"Um... Hey guys. What's going on?" Dipper said nervously.

"Hey Dipshit, you must love that hat huh?"

Dipper replied "Um, yeah I think I look pretty good in it."

One of the bullies replied back, "Well what would you think if I…"

They were interrupted by none other than Pacifica Northwest. "Hey asshole! I wouldn't touch that hat if I were you." Pacifica sternly said to the three men.

"Pacifica, what the hell are you doing here in Palo Alto? Shouldn't you be back in Gravity Falls?" Dipper cautiously said, unsure of what is going on.

Pacifica turned to Dipper, with a big smile and said to him, "Well I was so touched about what you gave me for my birthday a few weeks back and I felt I needed to do this in return for your birthday." At this moment Pacifica slowly walked towards Dipper and kissed him deeply.

The two separated, looking deeply into each other's eyes before rudely interrupted. "Wait, are you with this loser?" One of the bullies asked the two lovers.

"Yes!" Both Pacifica and Dipper answered, blushing right after. Speechless, the bullies turned around and walked down the hall to harass someone else.

After that incident, Pacifica finally was able to meet Dipper's parents for the first time. They absolutely adored Pacifica. It was during this time that Pacifica and Mable started becoming close friends.

The Northwest's enjoyed Dipper so much that when the month of December arrived, Preston Northwest asked Pacifica if she would like to have Dipper flown up to Gravity Falls so he can spend time with her before Christmas. Dipper excited to see his girlfriend jumped on the offer and flew from San Jose to Gravity Falls on the Northwest's private Boeing 737 Business Jet. Dipper could only stay for a few days, but during that time the two could not be separated. The night before Dipper would leave Gravity Falls, Pacifica decided to treat Dipper to a very special present. At 1:30 AM, December 23rd Pacifica tip toed quietly towards the one of many spare bedrooms in Northwest Manor where Dipper would be sleeping. She quietly opened the door to Dipper's room and quietly closed the door and locked it. She was been prepared for this for a while and she knew what she wanted. She continued to tip toe across the room, placing her "supplies" on the nightstand and then carefully got under the covers with her man. She started to slowly kiss Dipper, purposely trying to wake him up. After about 3 minutes, Dipper woke up startled in a panic. He turned to his left and saw Pacifica lying next to him.

"Pacifica!" Dipper quietly hissed at the beautiful girl lying next to him, "What the hell are you doing here!"

Pacifica sinisterly smiled at Dipper and said, "Dipper, you are so caring and loving, I love you so much and I felt that this would be the best Christmas present to show you how much you mean to me."

With a confused look on Dipper's face, Pacifica got up in bed moved to Dipper's ear and whispered "I want you to be my first, please let's make sweet love. I brought all the protection we need."

At this request, Dipper with his eyes as big as saucers glared at Pacifica. Dipper started thinking about what she just said, and without any vocal response, he turned to Pacifica and started to heavily make out with her with the hope between them that tonight will be both their first time.

That following summer, it was more business as usual in this crazy town. But this time around Pacifica would spend most of her time with the Pines twins. She would either have fun with Mable, spend one on one romantic time with Dipper, or join the Twins on one of their many mysteries.

This the Prologue to the huge adventure mostly involving the Pines twins, & Pacifica Northwest. This is my first FanFic ever, I wouldn't be surprised if it doesn't flow correctly. I just hope you guys enjoy this story.
