The following takes place after the events of 'Northwest Mansion Mystery'. I hope you enjoy the fanfic!
The Northwest Fest was very grand, full of rich folk and fancy catering. It seemed a bit more bustling since the 'commoners' of Gravity Falls crashed in, making the party a bit more lively. Dipper liked the thought of the rich and his kind getting along, establishing friendships and such. He did accomplish this, however, becoming friends with the most popular girl in Gravity Falls and helping her to become a better person. The young boy felt proud of himself for what he has done, and hoped for a better future for the Northwests- and hoped for Pacifica to establish a successful line. Dipper was taking a break from the party, and started to wander around the huge mansion where the party was held. Remembering the many dark halls that Pacifica and him ran though when chasing down the ghost, or looking out though the large window to the garden where Pacifica awkwardly gave Dipper a hug, he felt like he's been in this mansion for a long time. Almost like he lived here, but he only came and stayed here for about several hours or more. It was also sort of quiet, the echoes of talking and classical music coming from the main lobby of the mansion. He didn't mind the silence, though.
"Dipper? Where are you?"
Dipper heard the familiar voice of Pacifica Northwest down the hallways. He bolted to see where the voice was coming from, and saw Pacifica pop out of a corner from the hall he was currently in. She smiled once she interlocked eyes with the boy. "There you are," she confirmed playfully, and started walking towards him. "What are you doing here? I thought you were enjoying the party."
"No thanks, I'm a bit tired from dancing and talking," Dipper confessed once Pacifica was standing right beside him. "Thought I would explore the place."
Pacifica raised an eyebrow and crossed her arms. "You already did that when we were chasing down the ghost," she stated, a warm smile on her face.
"Yeah, I know, but I would just like to analyze. I never been in a mansion before, so I would like to see what mansions hold exactly." the boy replied. He then turned around to face a large painting he was currently inspecting, an 18th century lady in fancy clothes posing outside a garden. Pacifica followed his gaze, and admired the picture herself. The woman in the painting looked like an older Pacifica, but with a bit more makeup and lighter blonde hair.
"That's my great-great-grandmother, Hope Northwest." Pacifica explained. "Our family doesn't know much about her accomplishments, but I heard she ran a very successful hat business."
"That would explain the hat," Dipper pointed to the large pink sun hat that the woman wore with grace. Pacifica laughed shortly, Dipper following along. The girl then turned around to face the corner she appeared from, with a tint of worry. "Wouldn't you want to go back to the party? Mabel's been asking where you've been." she asked Dipper who was inspecting other parts of the painting. "We should go before your sister starts to get worried-"
"No, no, she'll be fine. Hopefully she's used to me just disappearing out of the blue," Dipper interrupted respectively. He then turned towards the opposite hallway, the hallway that leaded even further away from the party, the hallway that he didn't recognize and wanted to explore. It looked sort of safe, small lanterns installed on the walls lit the way. From his distance, Dipper could say many other hallways and doors that were just waiting to be explored. "Hey, do you want to go exploring?" he asked, breaking the somewhat awkward silence between him and Pacifica.
Pacifica jumped a little when Dipper turned around to face her. "Excuse me?" she asked again.
"I bet this mansion has many other things worth analyzing. Hopefully you can show me some of the hot spots, right?" Dipper said, as he walked a bit closer to Pacifica. She started to blush once Dipper was almost nose-to-nose with her. "C'mon, it'll be fun for the both of us." the boy beamed.
Pacifica, after a few seconds to think, let out a nervous laugh and nodded her head slowly. "Okay, that's fine. But we have to return to the party once we're done." she ordered. Dipper pulled away from their closeness and raised a fist to the air, releasing a small 'yes' though his smile. "The mansion is really big, so you have to stay by me at all times," Pacifica instructed. "Got it?"
Dipper smiled and agreed with Pacifica's little rule, and grabbed the girl's hand gently. Pacifica blushed with Dipper's gentle touch, as the both of them started their way down the hallway.
