[Chapter 4: Sleepover]

Dipper and Pacifica entered the attic bedroom. Mabel was already sat on her bed, her pet pig Waddles on her lap. The moment she saw Pacifica wearing the sweater, her face lit up.

"Oh my gosh! You're wearing it!" She yelled happily at seeing the heiress in a sweater.

"Yeah." Pacifica pulled at the sweater to stare at the llama drawing. "I like it; it's very fluffy. Did your mom knit it? I didn't see any label." As she talked, Dipper sat on his bed and Pacifica sat beside him.

"Nope! I knitted all my sweaters myself." Mabel eyed curiously which bed Pacifica had chosen to sit on, but guessed she didn't want to sit on her bed because of Waddles.

"Really?" Pacifica's eyes widened in disbelief, since she had seen her wearing a lot of different sweaters. "Sounds hard."

"Nah, with a little bit of practice and imagination I can make a sweater a day." Mabel shrugged and waved her hand dismissively. "I'm sure you could do it too if you tried."

"Oh, Pacifica is very imaginative." Dipper commented.

"Is she now?" Mabel put on a playful tone. "You seem to know a lot about Pacifica, bro-bro."

"Yeah, we've been talking all day." He shrugged.

"Just talking? I heard a scream earlier." Mabel grinned and began waggling her eyebrows. "What were you two doing alone up here, huh?"

Dipper didn't get the insinuation and raised an eyebrow quizzically, but Pacifica's face blushed terribly and Mabel saw it.

"No way! You two were making out!? That's why Dipper's bed is stripped!" Mabel's mouth opened in a mixture of surprise and amusement.

"What!?" Pacifica squeaked as her blush deepened.

"No, no. The bed is stripped because Pacifica had to use the sheets to cover herself." Dipper quickly explained.

"But… why did she have to cover herself in the sheets?" Mabel tilted her head in confusion.

"Because she was naked." He answered matter-of-factly.

"I wasn't naked!" Pacifica, whose face was now the color of cherries, blurted out. "I still had my bra!"

"Oh! Dipper, you don't know how to unclasp a bra? I can show you!" Mabel chirped happily, completely misunderstanding Pacifica.

"I didn't need to. She simply lowered the shoulder straps." Dipper explained and Pacifica's jaw could've hit the floor if it hadn't been attached to her face.

"I-I-I…" Pacifica babbled, wide-eyed. "You can't be serious. Are you two messing with me!?" She elbowed Dipper in the ribs.

"Ouch!" Dipper rubbed his side. "Of course we are!"

The twins burst into laughter. Pacifica frowned and crossed her arms over her chest, feeling upset at the situation. The door to the attic opened without warning and Stan got in the room.

"You left this in the oven, Pumpkin." He gave Mabel a bowl of cookies. "Pay attention when using the kitchen or one day you'll burn the Shack down."

"S-sorry, Grunkle Stan, I forgot" Mabel wiped the tear of laughter off her cheek and grabbed the bowl.

"Careful, they're very hot." He warned and then had a look at the situation. Dipper and Mabel were red from laughing and Pacifica was red too, but frowning instead. Stan shrugged and decided he wouldn't probably understand it even if he asked. "Come with me, Northwest, while those cookies cool off. Let's get you a mattress." He told Pacifica.

Pacifica jumped up from Dipper's bed and followed him outside the bedroom. As they were going down the staircase, she hissed.

"I've a name, Old Man."

"I also have a name, kid." Stan replied.

Pacifica stopped for a second and then continued following him. She didn't know the layout of the building and the last thing she wanted was getting lost now. She eyed him and sighed.

"Have you called my parents yet, Old—uh… Mr. Pines?" She asked.

"Yeah."

Pacifica raised an eyebrow when she didn't get a more elaborated answer. She waited a second for Stan to continue and then she insisted.

"And what did they say? Are they mad at me?" She asked warily.

"Don't worry about that now." Stan continued walking.

"So they're mad. Well, I'm busted then. I'll spend what's left of my summer vacations in my room staring boringly through the window and all of this because I wanted to know if I did the right thing…" Pacifica lowered her gaze and sighed. "But… what would you know about it anyway."

"I know, kid." Stan sighed this time and stopped walking. "When I was young, my brother was the genius and I was the black sheep of the family. When I was seventeenth I was kicked out of my house and my parents never wanted to know anything of me again. Actually, I think they never did… Trust me, I know the feeling."

"Oh…" Pacifica looked at him in the eyes to make sure he wasn't lying to her, because Dipper had told her he was a conman, but the heiress decided that he was sincere. "I'm sorry. I didn't know."

"Don't apologize, kid. It wasn't you who kicked me." Stan waved his hand dismissively. "But, if you ever get in… you know, trouble at home or something, know that you are always welcomed here." He reassured the girl.

"Thanks, Stan." Pacifica smiled and he reciprocated the smile.

Stan opened a door that was painted the same way the corridor walls were and they got inside a dark room.

"I used to have my wax museum here but the kids butchered all the figures one night saying they were possessed or something." He explained and Pacifica had a quick look around herself as if expecting a wax figure to attack her. "Now we store stuff here. It's easier than carry it up to the attic.

Pacifica nodded and saw several objects that brought memories to her mind, like dancing tiles piled up in a corner from the party at the Shack a month ago. There were also some that she didn't know, like a rolled up blue carpet with the recycling symbol on it. Stan walked behind a closet and picked up a mattress and some sheets.

"Here, you carry the sheets and I carry the mattress." He handled her the sheets.

"Where is my room?" Pacifica asked.

"Your room?" Stan raised an eyebrow. "This isn't a hotel. You're sleeping with the twins."

"What?! I can't sleep with them! What if one of them snores?" The heiress complained.

"Well, you can either take the risk with them or you can sleep with me, but I'm definitely going to snore." He shrugged. Pacifica puffed out her cheeks and Stan laughed. "That face might usually work for you but believe me, I can't make a room magically appear in the Shack. Only Soos on rare occasions can."

"Fine." Pacifica groaned.

They came back into the twins' shared bedroom. Dipper's bed had its sheets again and Dipper was lying on it, reading a book. On the other bed Mabel was knitting a new sky blue sweater.

"There you go." Stan leaned the mattress on the wall next to the door and then he gestured to the twins. "When you kids go to sleep help her with the mattress and the bed sheets." He instructed and left to watch his favorite TV show.

Dipper put aside his book and grabbed his vest.

"C'mon, let's have a look at the crystal."

"Not so fast, Dipper." Mabel stopped his hand. "First off, tell me all the details of your adventure. It's not fair that you have a look at that crystal while I have no idea what it is!"

"Right, sorry." Dipper apologized.

"But, while you're at it, we'll deal with these cookies! They have probably cooled off enough!" Mabel placed the bowl on her lap. "C'mon, sit with me, Pacifica!" She beckoned the heiress.

"I—Um..." She hesitated. "I would rather sit on Dipper's bed."

"Why? Waddles is downstairs." Mabel said matter-of-factly.

"It's not the pig, Mabel. You bed is a little… sticky." She explained.

Mabel looked at her quizzically and then patted her sheets.

"Well, now that you mention it…"

"I told you not to eat in bed." Dipper reminded her with a knowing smile.

"I know, but there's nothing like eating while lying in bed!" Mabel countered with a grin.

"And…" Pacifica sat on Dipper's bed. "…I wouldn't want to stain the sweater. It's not mine after all."

"Oh, but you can keep it!" Mabel chirped happily. "I can make more! Look, I was making this one to cheer me up when it's cloudy!" The cheerful brunette held out the sweater she had been knitting before. It was sky blue with a puffy cloud in the chest.

"You could sell those." Pacifica suggested.

Mabel gasped and held the sweater protectively.

"Nuh-huh. I love every single one of my sweaters! I'm not selling them."

Pacifica stared at the sweater Mabel had given her and smiled.

"Thanks for giving me this one then."

"I'm glad you like it!" The cheerful brunette chirped happily. "You wanna try some of these cookies? I bake them myself."

The heiress eyed the cookies in the bowl on Mabel's lap. Each cookie had plenty of chocolate tips, making Pacifica' mouth to water but she had to decline the offer.

"I can't. My parents don't allow me go off my diet and I've stay in shape."

Dipper rolled his eyes and sighed. He still couldn't understand that.

"And what shape is that, a noodle?"

Pacifica felt offended at his comment and shot him a glare, causing Dipper to back off.

"What my dumb brother is trying to say…" Mabel glared at Dipper too and he felt cornered all of a sudden. "…is that you're fine and you're not gonna become a sumo wrestler overnight for eating a few cookies."

"Yeah!" Dipper's voice broke. "And you look great with those…" He gestured to her chest but bit his tongue before it said anything else. "Um… you have a nice slim figure. Besides, your parents aren't here."

"Just eat all you want." Mabel added. "Look at me! I eat like twenty or thirty of these every day and I'm not fat."

Dipper's eyes bulged out and noted mentally to have a look at his sister's diet.

"Let's not exaggerate either, Mabel. Pacifica and you are not the same. You have a very active behavior and burn all the fats in…"

As Dipper began explaining to his sister how her body used what she ate and Mabel ignored him, Pacifica analyzed very careful what she had just heard from Dipper's mouth. 'He thinks I have a nice figure?' She thought and zoned out, focusing her gaze on how Dipper made gestures with his hands to explain himself. The heiress thought he looked cute and sighed dreamily. She was snapped out of her daydreaming by a cookie bowl nudging her shoulder.

"Yeah, yeah, Dipper. I'll reduce the daily intake of cookies to less than a dozen. Take one, Paz-Paz!"

"Paz-Paz?" The heiress raised an eyebrow.

"I call Dipper 'bro-bro' and you're 'Paz-Paz'!" She chirped happily. "Now take one!"

"Alright, alright." Pacifica took a cookie and eyed it warily. The heiress didn't know what to expect of it, considering Mabel had cooked the cookies.

"C'mon, Dipper! Tell me, tell me! Did you guys meet a hot elf or something in your adventure? I want ALL the details!"

Dipper rolled his eyes and began telling the events that had taken place that day, omitting some details about Pacifica's personal life he guessed the heiress didn't want anyone to know. In the meantime, Mabel was listening and already on her third cookie. Pacifica guessed that the sooner the better and gave a small bite to her own cookie expecting the worst. However, a sudden sweet flavor filled her mouth and she couldn't help but moan. Dipper stopped halfway through the story and the twins eyed her curiously.

"Was that me?" Pacifica asked, a little surprised, and both twins nodded. "Sorry, I thought these little chocolate tips would be bitter but they're sweet!" The heiress quickly devoured the remaining of her cookie.

"You don't have chocolate in the manor?" Mabel tilted her head and looked at the heiress quizzically.

"We have the best imported European chocolate." Pacifica said proudly. "But it's bitter, without milk or sugar. It's the one my parents like."

Mabel smiled and placed the cookie bowl on Pacifica's lap.

"Here, eat all you want. I can make more."

"Thanks." Pacifica smiled broadly and gladly took another cookie.

The twins exchanged a look and smiled warmly at how easy it had seemed to make the heiress happy. Dipper continued telling the story, causing Mabel to giggle at some points until he got to the part where they arrived at the Shack.

"I honestly don't know how we did it, but the harpy somehow lost her balance and crashed on the ground with us." Dipper commented while cupping his chin, deep in thought.

"Yeah." Pacifica shuddered, remembering the terrible vertigo sensation she had experienced. "The first time I head-butted her, she didn't even flinch. The second one did the trick though, but I don't know why."

Dipper stared at her intently, trying to find out what had happened. Pacifica felt a little self-conscious at his deep stare and wished she had some makeup on.

"Of course!" He suddenly yelled. "Are those earrings pure silver?"

Pacifica touched her hoops earrings and smiled smugly.

"Pffft, of course they are."

"That's it!" Dipper opened his journal and flipped pages until he reached the index of the bestiary section. "Cursed ones, hybrids, necrophages, relicts, specters and vampires are very sensitive to silver, and the harpy is in the hybrids section!" He read aloud and then began tapping his chin. "This would go better in each category's page under weaknesses instead of only in the index. I'll fix that tomorrow. Anyway, let's have a look at that crystal." Dipper grabbed his vest and opened it on his lap, revealing the blue crystal. "If my theory is correct, harpies use dreams to power up their crystals. When a predator goes into their nest, they feel attracted to the crystal and touch it. Then, the crystal sort of vibrates and sends a distress signal to any harpy nearby. However, it's no longer attached to the mountain wall so if I do this…" He extended his hand to touch it.

"Wait!" Pacifica stopped him. "You sure that's a good idea? I'm not looking forwards to be lifted in the air again anytime soon."

"Relax." Dipper said calmly and held the crystal in his bare hand. "See? It's not vibrating because it's not attached to the wall. It just glows a little. No harpy is going to come looking for it."

"I see something in it." Mabel commented, narrowing her eyes and leaning closer.

"Yes… There's some sort of shapes or something. It has to be the dream stored in it." Dipper raised the crystal and rubbed it with his thumbs to fuel the glow.

"Wait, I know that garden…" Pacifica leaned closer too.

Inside the crystal appeared the image of Pacifica wearing a long purple dress with black puffy shoulder sleeves smiling at the dreamer. The image moved as the dreamer walked with his eyes fixed on the heiress. It suddenly shook violently and Pacifica began to laugh. The dreamer had bumped into a column. Then it began to loop again from the start.

"That wasn't a dream." Dipper said wide-eyed. "That was me at the party!"

"Maybe you dreamed about that day." Pacifica suggested and rubbed the crystal to see it again.

"Oh my gosh, Dipper." Mabel said with a grin. "Did you really bump into a column because you couldn't take your eyes off Pacifica?"

Dipper was too bewildered to hear his sister's remark.

"Of all people in town and of all the crystals that probably were in that mountain, I go and take my own dream!" He turned to Pacifica. "And precisely one where you make an appearance! What are the odds?"

"That has to be destiny!" Mabel chirped happily.

"Mabel, you know I don't believe in destiny or superstition in general." Dipper rolled his eyes.

"I don't know what it was, but I'd buy lottery if I were you." Pacifica joked and the twins giggled. "Or perhaps that mountain is filled with your dreams because the harpies are too lazy to fly for ten minutes more and reach town."

"Maybe…" Dipper pondered about it and noted mentally to search for some kind of dream protection. "But it's curious that I picked up a dream where you appear."

"C'mon Dipper," Pacifica put on a playful smile. "I'm not gonna get mad if you admit you dream about me every day."

Dipper blushed and was about to counter but Mabel stepped in quicker.

"Nah, Dipper only dreams about Wendy." She commented in a playful tone.

"I don't dream about anyone!" He blurted out and blushed.

Both girls burst into giggles but Pacifica noted mentally that priceless information and began to wonder how she could compete with the redhead.

The twins and Pacifica continued talking for a while, exchanging questions to know each other better. Then, Pacifica yawned all of a sudden and Dipper did a quick check on the clock.

"We should better go to sleep." He commented.

"What time is it?" Mabel asked.

"A few minutes past midnight."

"What!?" Pacifica's eyes widened and glanced at the attic door. "And you are allowed to be up this late?"

"Yeah, Stan doesn't mind." Mabel shrugged. "Let's get your mattress ready. What do you think, Dipper? Between our beds or by the door?"

"Definitely between our beds." Dipper nodded. "We don't want to step on our guest if we have to go to the bathroom or something during the night."

"Alright. C'mon, give me a hand here."

"Why don't you call the servants?" Pacifica asked.

"No servants, remember?" Dipper replied.

"What about Jorge?"

"Jorge?" Mabel tilted her head in confusion.

"That big guy with a question mark on his t-shirt."

"Oh, but that's Soos." Dipper clarified. "He's not a servant, he's a friend who works here." He walked up to the mattress lying on the wall and tried to lift it, failing after a few tugs. "Um… Mabel, can you give me a hand here?"

"Sure thing, muscle man." The cheerful brunette teased and Dipper rolled his eyes.

Between both twins they easily placed the mattress between the beds and put the sheets on top of it. Mabel lent Pacifica one of her nightshirts and in a few minutes everyone was on their own bed ready to go to sleep.

"Night, Paz-Paz. Night, bro-bro."

"Night, Pacifica. Night, Mabel."

"Night, Mabel. Night, Dork."

Dipper smiled and Mabel giggled in the dark.

Time passed and the moon rose in the sky. Dipper couldn't sleep. At this hour he usually was reading in his Journal, but he couldn't simply turn on his reading light when they had a guest sleeping in the room. Mabel was used to the small light, but Pacifica would probably have a problem with it. Dipper rolled on his bed and faced both Mabel and Pacifica. Mabel was soundly asleep but Pacifica was constantly changing positions on her mattress.

"You can't sleep?" Dipper whispered.

"I'm trying, but this old terrible mattress insists on giving me a wonderful massage on my back." The heiress replied sarcastically.

Dipper chuckled and hesitated for a few seconds.

"Well… my mattress is alright and this bed is… big enough for both of us."

"I'm not getting in your bed." Pacifica quickly replied and, although the night's darkness hid her blush, it didn't hid Dipper's offended face. "I mean… If your sister sees us she won't shut her mouth about it!"

"Whatever you say. Enjoy your back massage." Dipper shrugged and rolled onto his other side to face the wall.

Two minutes later Pacifica reluctantly climbed into Dipper's bed. He rolled to face her with a knowing smile.

"Shut up and not a word about this to anyone." She grumbled.

Dipper chuckled and handled her some of the bed sheets. The heiress gladly covered herself, considering the night was a bit chilly, and accidentally brushed Dipper's feet with hers. Dipper gave a yelp of surprise and backed off.

"Your feet are ice cold!" He hissed.

"It's a circulatory problem!" She hissed back. "My feet and hands get cold when I'm lying down. It's nothing serious though, but I have an electric blanket in the manor for chilly nights."

"Nothing serious?" He whispered in disbelief. "You'll get a cold from that! C'mere, my feet are warm." Dipper snuggled closer and placed his feet on top of hers.

"Thanks." Pacifica muttered and lowered her face to hide it under her bangs. She wasn't sure the room was dark enough to hide her current blush.

When her cheeks stopped burning and her feet were already warm, she raised her gaze and stared into Dipper's hazel eyes with her blue ones. Pacifica had never been insecure about anything, but those eyes made her nervous. She stared into them for long, trying to find answers, but she found none. All she saw in those eyes was kindness and tenderness which caused her to begin feeling that pleasurable tingling inside her chest. Pacifica smiled and found the answer she had come looking for that morning to the Shack. She was in love. The heiress sighed happily and closed her eyes, falling deeply asleep.

Dipper noticed how she opened her mouth slightly and how her face rested completely on the pillow. Her chest began rising and falling rhythmically and he guessed she had fallen asleep. Dipper thought she looked cute while sleeping, but there was a lock of blonde hair across her cheek. The boy extended his hand and pushed it away gently so to avoid waking her up. Then, Dipper sniffed the air a few times. There was a smell in the air, like fresh flowers. He soon realized that it was Pacifica's lilacs shampoo and the smell was coming out of her hair. Dipper had to admit that she had good taste for shampoos and, since she was sleeping now, he seized the opportunity to touch her hair again. Dipper began stroking the hair lying between them on the bed and wondered how she kept it so full and silky. Pacifica felt the soft pulls of her hair and mumbled in her sleep, snuggling closer and grabbing Dipper's forearm to make him stop.

"Well, there goes my fun. And I can't move now." He muttered and sighed.

Even though Dipper couldn't move anymore without accidentally waking her up, he couldn't deny either that he liked the feeling of her hand. A month ago he would have never got so close to Pacifica Northwest, let alone share a bed with her or letting her hand touch his forearm, but many things had changed in this past month. Dipper had learned that Pacifica was determined, a teaser, funny and unfortunately a sad girl. Dipper couldn't stand seeing someone being punished for doing the right thing and then feeling sad about it, so he would gladly be her friend. As those thoughts came into his mind, he stared at Pacifica's face. She looked very calm and relaxed while sleeping, but Dipper would love that she opened her eyes just so that he could see those deep blue eyes sparkling again. Dipper felt a warm feeling in his chest and instinctively snuggled closed to the heiress, smiling stupidly.

Then he immediately backed off wide-eyed and looked at Pacifica with complete different eyes.

"Uh-Oh… C'mon, not again." He groaned as he realized he wasn't going to stop thinking about his new crush all night long.

Far away from Gravity Falls, the party the Northwest had attended to had ended a few hours ago and Preston and Priscilla were staying in a luxury hotel for the night. They would go back to the manor the next day after lunch.

Preston was as usual sitting in an armchair, an apple cider glass in his hand and staring at it as if it were the most entrancing thing in the world. On the other hand, Priscilla was staring at herself in the mirror. She was brushing her hair endlessly, since if she didn't do that before going to sleep her hair tangled.

The news coming from Gravity Falls had angered the Northwest patriarch. Firstly, Pacifica's tennis instructor had called telling him that his daughter hadn't gone to class. When he had called to the manor, none of the butlers had any idea of where she was. Completely filled with worry and about to call the police, another call came but this time it was from that UFO fanatic turned conman, which apparently was a relative of the boy who knew all the dirty secrets of the past of the Northwest family, saying that his daughter was in that hovel of a tourist trap.

A hand on his shoulder snapped him from his thoughts.

"Are you still thinking about Pacifica?" Priscilla asked and he nodded. "You don't have to worry about that anymore. We found her. She's safe."

"I know." Preston sighed. "And I'm glad nothing happened to her, but I can't stop thinking of the bigger picture."

Priscilla raised an eyebrow in puzzlement and put the brush in a drawer.

"What bigger picture? Pacifica is just staying overnight with a few friends. True, that hovel isn't the most luxurious place but I'm certain she made sure nobody saw her getting in, so no harm is done to the family reputation."

"The worry and the sudden relief made you forget where the original problem was, Priscilla. Why did Pacifica skip tennis class?" Preston began tapping the apple cider glass. "She knows how important it is for her to learn tennis. Every big business deal is either arranged in tennis or in golf and, although she's great at mini-golf, she definitely needs to perfect her tennis skills." He paused for a second. "Do you think she skipped tennis to go play with those Pines twins?"

"Maybe." Priscilla pondered about it. "We'll have to ask her tomorrow."

"Because if she did," Preston continued with a frown. "it means she has disobeyed us to go play with those kids, and she had never done that before." He sighed. "Those two twins are a bad influence for her. Especially that boy. She mustn't see them again."

"You're exaggerating." Priscilla rolled her eyes and sat on the bed. "It's probably just a phase."

"No." Preston shook his head. "When we were her age we never went through such phases."

"Well, times change. Nowadays a kid with internet knows more than a bachelor back in our time. It's natural. You'll see how nothing happens." Priscilla shrugged.

"And what if something happens?" Preston's eyes widened. "No, no. I already made my mind. She is our only daughter and I'm not taking any chances. Pacifica will go to tennis, she'll be the first of her class in school and one day she'll lead the company without any trouble, and she has to stop seeing the twins to do so."

"Let's assume for a second that you're right and she has befriended the twins." Priscilla acted as the voice of reason. "Pacifica isn't going to like that you forbid her from seeing her friends. She'll hate you for that. Maybe I should talk to her instead and—"

"No." Preston quickly stepped in. "It's my company and it's my responsibility. Pacifica hating me in exchange for a future life full of opportunities is a risk I'm willing to take. I'm just choosing the lesser evil."

A/N:

FYI:

Pacifica having cold feet and needing Dipper to warm them is a reference to the TV show 'Chuck'.

Stan's and Pacifica's background having trouble with their parents gives them the perfect reason for bonding.

I want to remark that Pacifica came with a crush on Dipper, and Dipper developed a crush on her that night. That will be further developed in the second episode of the trilogy.

Preston will act as the main antagonist of the ship. Sadly, he's doing the wrong thing for the right reasons.
