Mabel could barely see anything through the dark. The night sent of chills which were unusual, seeing as it was in the middle of summer. Something was off, Mabel felt. But it was all a different type of off. She got up and turned the fan off, the chills she felt were suddenly gone.

The eighteen year old sat on the window sill then pulled the curtains apart, letting a bright and calming light from the moon enter the room through the triangle shaped glass. She stared out the beautiful night offered to her by Gravity Falls. It was absolutely breathtaking, the scenery. She did not often have these kinds of nights back in Piedmont and with this being her last summer before college, she knew that she was going to miss these kinds of nights.

"Why so occupied, m'lady?"

A small smile showed up on her lips. She did not even need to look to know who it was. That voice, she remembered that voice clearly and she was sure she would remember it for eternity. She heard the light steps he took towards her and felt the warmth radiating from his body when he slipped his hands all the way to her stomach.

"I'm just thinking." Mabel murmured, leaning in closer to him

"About?"

"Stuff." She answered

"Like?"

She shrugged, "College." She sighed, "After this summer I'll be gone for so long."

"You won't be back next summer?" She felt the frown forcing its way to his face

She shook her head solemnly then turned to face him. She stared at his unruly blond hair, his charcoal black eyes, those which never seemed to fail to mesmerize her. She looked at each of his features, memorizing every freckle that sprawled across his tanned skin.

"I'm... I'm gonna try." She tried to lift his spirits up, "I'm gonna try and at least visit you here. Wouldn't want you to get too lonely now."

He faked a smile for her. "I could go visit you." He offered

"No thank you." She politely declined, "I'm gonna go live with Dipper there since we'll go to the same college and all and I just don't want to see you two fighting."

"Well I can still try and win his trust." He stated

"Sure, you think after you turned him into a living puppet and tortured his body he'd still trust you." Mabel responded

The blond chuckled lightly, "That's putting it badly. I'd like to call it borrowing his body for a couple of hours."

"But still, no. You can't visit me there."

"What if I never show myself to him? Or change bodies? You know that there are a lot of souls willing to make a deal with a demon." He said

"No, no, I like this body on you." She smiled at him

"I'm gonna miss you so much then." He frowned once more, looking down at the ground and avoiding her gaze

Mabel furrowed her brows then pulled his chin up to make him look at her. He rested his forehead against her own as she wrapped her arms around his neck. She stared at his enchanting orbs and he did the same.

"Don't be too hard on yourself now." She whispered, her voice laced with concern, love, and care

"I'm a demon who knows anything but make himself feel better, of course I wouldn't be hard on myself." He smirked a bit

Mabel's smile widened, "C'mere you."

He closed the small gap between their lips with pleased smiles on both their faces. They moved in a rhythm they have created after almost three weeks of stumbling and the rest of a year of being used to the taste of each. Mabel pulled him in closer to her. The heatness in the room spread and grew even more. The chills left in Mabel's body were surely forgotten with the contact he left to her body even through the thick layer of clothing.

"Mabel!"

The two almost jumped apart because of the new person who had entered her room. Her brother's expression curled up from confusion to downright anger. He could not believe her sister would let a boy in to her room at almost midnight and make out with him. He could not find the right words to say to his sister. Should he guide her to the right way by telling her this was wrong or should he get angry so she would know what she did wrong? All of the rational sides of Dipper left as he lashed out on his sister for her faults.

"What is this?!" He snapped at her

Mabel could not look him in the eye. Her cheeks blushed in pure embarrassment. She knew she could not talk to her brother with proper reasoning if he was angry.

"Dipper, please, I can explain!" she furrowed her brows

The least she could do was try to reason with him.

"What? What can you explain Mabel? That, that you're just letting this guy in here and you're throwing yourself to him, is that it?" He yelled, "Mabel I thought you knew better!"

Mabel bit her lip as she tried to not let her tears fall. Her brother's words hurt and he knew that it did. Mabel knew in herself that she was not the kind of girl Dipper was accusing her to be.

"How long have you been doing this?" Dipper had calmed a little bit

"Look, it's not what you think." Mabel looked at him, teary eyed

"How long have you been doing this?" He repeated, now back to his former tone

She whimpered at his voice and almost cowered behind the curtains behind her.

"She's telling the truth." The other person in the room decided to speak up

Dipper glared at the black figure standing near Mabel. He could not quite see who was in there and the voice was not in anyway familiar.

"Who're you?" Dipper asked quietly, squinting in the dark

The other person sighed and started to walk to where it was sort of bright but Mabel already had a hand on his arm, not letting him to.

"No, please, don't." Mabel pleaded

He turned to her, "But Shooting Star, I-."

"Sh-Shooting Star?" Dipper's eyes widened

He searched for the light switch near the door and flicked it on. He wished his eyes deceived him as the sight of a blond boy with fairly tanned skin and black eyes wearing a gold vest and white undershirt and black dress pants took over his sight.

"...Bill?" Dipper could only stare at him

"Dipper I'm so sorry." Mabel sobbed

Bill immediately went to her side and comforted her. She buried her face in his chest and he just hugged her tighter.

"Get away from her!" Dipper ran to his sister and pried the taller guy away

"Dipper!" Mabel tried to stand up but Dipper forced her to sit down, "Dipper he did nothing wrong!"

"Why are you here?" Dipper glared at the other one, ignoring his sister

"Isn't it obvious, Pine Tree?" Bill nearly groaned

"Don't tell him!" Mabel told Bill but it was as if she was invisible

"Your sister is nearly my fiancée, Pine Tree! Well she would've been if you didn't jump come in here!" Bill continued

Dipper felt his legs weaken. His sister? The fiancée of his archenemy? The fiancée of a demon. It was all just too surreal.

"And I would've told him yes." Mabel just had to add insult to the injury

"No, Mabel. You are not marrying him." Dipper tried to be as stern as possible

"Dipper this is my life." Mabel retorted

Dipper was taken aback. This was the first time she had ever decided against him. Sure she was the older one but he was the matured one so his opinion was more entitled to be the trusted one.

"Go." Bill said to her, "Go follow your brother."

Mabel breathed in deeply and went over to hug him tightly. She rested her chin on his shoulder. His right hand hugged her back and his left was in her hair.

"But I wanna be with you!" Mabel said weakly at the person in front of her, tears streaming from her face

"No Mabel," Dipper looked at her with a hard expression, "it's either me or him."

"Mabel wake up!"

Mabel looked around and saw her brother shaking her awake. She stared at him for a while before nodding.

"You had a nightmare?"

"I'm fine, it's fine." Mabel responded albeit a little bit sleepy

"Well," Dipper started, "it didn't seem like a regular nightmare."

"Dipper, I told you, it's fine. It's nothing to worry about." She replied, "Now let's go! Grunkle Stan wouldn't want to be waiting forever."

Dipper nodded then pulled out from the gas station and continued on driving, heading over to their destination, Oregon.

While on the way, Dipper could not help but think about the change they have been through since the last time that they were there. Dipper was now an engineer. He never dreamed of becoming an engineer but he guessed it would be for the better than becoming a host of a ghost hunting show. Mabel had finished fashion design and had dreamed of making her own fashion line. Dipper was proud of his sister for achieving her dreams. They were young and ready to take on the world, Dipper knew that it was going to be a long, happy ride for the two of them.

It had been years since they had last stepped foot in the little place. Five years had surely gone quickly for the two of them and most especially their two great uncles living in the woods. The two were absolutely excited when they told them that they were visiting for the summer. Sure, Dipper missed his grunkles but he just wanted to forget.

It was a long drive from Piedmont to Gravity Falls and it was starting to frustrate him. Especially the fact that he had seen the same tree with the burn mark the tenth time that day. Dipper felt like he was being played at over and over again and the aggravation was just building up.

"Dipper look!" Mabel announced, "We're here!"

And he gave a sigh of relief as he saw the sign of Gravity Falls a few meters ahead of them.

Mabel was the first one to hop off the car and give a huge hug at her grand uncle.

"Grunkle Stan I've missed you so much!" Mabel greeted

"Missed ya too, pumpkin." Stan responded, hugging her back

"Where's Grunkle Ford?" Dipper asked as he unloaded his and his sister's bags off the trunk of the car

"You know Ford, always in his study." Stan answered

Mabel walked over to her brother and helped him with her baggage. She grabbed her bag and the huge pink sewing kit she owned and made her way inside. She went up to the second floor, to their attic bedroom. She put down her bag and held the doorknob when she heard a thud coming from inside.

That's weird. Mabel furrowed her brows, Grunkle Stan said that Grunkle Ford's in his study. And Soos and Wendy don't work here anymore.

"So who's in there?" Mabel whispered to herself

"Anything wrong?"

Mabel turned to the stairs then grinned widely as she saw her other great uncle coming up the stairs. She enveloped him in a hug and he did the same to her.

"Uh, Grunkle Ford," Mabel started, "you wouldn't happen to have another helper, right?"

"Helper? We haven't had a helper since that weird guy worked here." Ford responded

Weird guy? Does he mean Soos?

"Oh, okay. Thanks." Mabel gave him a smile then the man went back downstairs, Mabel guessed that he was going back to his study room

She breathed in deeply and faced the aging wooden door.

Alright Mabel, you've kicked gnome butt and got rid of that dude that looked like Big Foot in college. Anything that might be in here is anything you can handle.

She stared at the door for a while before turning the knob and pushing the door open.

Only to find nothing.

She breathed a sigh of relief then entered the place that looked exactly like the last time she was in there.

Just one summer.
