Chapter one; Ten years later

Rain was pouring heavily down to earth as a shadowed figure walked through the streets with groceries in hand. He was wearing a black fedora along with a black trench coat. Underneath he wore a red shirt along with a pair of jeans. Completing his look was a pair of black sneakers. The young man made his way to his RV, that was standing in a parking lot. He didn't exactly know what the time was and he didn't really care. All he wanted now was a bit of piece and quiet.

The name is Dipper Pines. If you're hearing this, you probably tuned into my inner monologue, but that isn't really important.

The young man smiled proudly as he noticed a figure lurking behind him. Of course someone would try and rob him now. He was practically vulnerable, or so they thought.

I'm a detective of some sort and I love my job. I get to solve mysteries for a living and I make a lot of cash. I was practically living my dream. I'm not just any old detective though. I'm the person they call if paranormal activities start to take place. I'm here to solve mysteries that other detectives can't. I work for the government now. I always knew what I wanted ever since a particular summer in Gravity Falls. After all when a twelve year old schools top government agents, what better thing is there to do than hire him.

The young man put his groceries down and reached into his trench coat. He slowly pulled out a gun that was similar to the magnetic gun he used a particular summer when he was twelve. He turned a dial and it pointed to the words freeze. He loved making people think they had an upper hand when he was actually in charge.

"You know I can hear your loud footsteps in the rain. You should work on being more quiet." The twenty two year old stated as he rolled up his long black sleeves, revealing two tattoos on the young man's arms. A triangle was neatly placed in the center of the circle and other shapes was tattooed around it. They were well known as Cipher wheels. It must have been painful at one time in the young man's life. A promise from a particular triangle that vowed to return. The figure remained silent as he stepped out of the shadows. He was wearing a hood that was tattered and ripped, and his shorts didn't look any better. His feet were blue from the cold. Dipper sighed as he noticed the knife the man about his age had gripped firmly.

"I just want the food." He explained as he held out the knife towards the young detective. Dipper smiled as he put his gun away. He unlocked his RV and picked up his grocery bags. He wasn't in the mood for a fight and he was pretty sure the other man wasn't either.

I definitely wasn't in the mood for a fight and besides he looked exhausted to me. I'd rather pay it forward than arrest the poor guy.

"Put down that stupid thing and I'll make you a sandwich. I'll even let you spend the night." Dipper proposed as he held the door open.

"What?" The thief asked shocked as he lowered his weapon. Dipper chuckled softly as the man stared at him in awe.

"I think you'll get more out of the deal. Besides I'm tired and I haven't slept in a while and I can clearly see that you haven't either. So I'm asking nicely, put down the weapon and join me for dinner. I would enjoy some company."

"You're serious? I just tried to rob you." He reminded the detective.

"Bygones will be bygones, besides I believe in a little thing called pay it forward. What's your name by the way?"

"Daniel." The young man stated as he sheathed his weapon and entered the RV.

I know that natural logic would shout that you can't invite a criminal into your house, but hey what's the worst he could do. I have years of training behind me and the worst he could do was steal my milk.

The next morning Dipper had sent Daniel on his way with a blanket and a bit of money so he could hold out a bit and only requested that he went and got himself a job, otherwise Dipper would unfortunately have to arrest him next time he was in the city. It wasn't until his communicator rang that the excitement started.

My communicator works like a cellphone, but is much more sophisticated. It has a very secure line and was almost impossible to hack. It holds all the information of previous jobs I completed and it's internet is much faster.

Dipper quickly flipped through his emails and discovered a pleasant surprise. His next job was in the very town he missed and longed for with all his heart. Gravity Falls. Dipper smiled brightly as he closed his communicator and placed it back into his trench coat. Luckily he wasn't exactly far away from that very destination.

The young detective made his way through his messy RV and flopped down in the drivers seat. Dipper frowned a bit as he caught sight of his tattoos. It was a constant reminder that Bill might come back. How it was possible it was beyond him. Grunkle Stan was pretty sure that he was completely gone and so was his uncle Ford, but his skin told a different story.

Dipper shook his head as he fastened his seat belt and placed the key into the ignition. He wasn't going to think about past 'What if's' and 'Maybes'. He was going to focus on the present. Maybe Mabel had rubbed off on him.

A few hours later, after several stops Dipper finally arrived in Gravity Falls. When he first entered the town he immediately felt his tattoos start to act up. Unfortunately for Dipper, Bill had decided to enchant the two circles, giving Dipper unusual qualities.

When I first discovered these qualities they were quite painful, but after a while I started using them for everything. I knew Bill was a mystery and not at all clueless, but this was really confusing. He had practically evened the odds. Bill was dangerous and I needed to keep my guard up at all times.

As Dipper continued on the road he suddenly heard police sirens behind him. Dipper sighed in irritation as he pulled over. He opened the window and waited for the cop to walk up to him.

"License and registration..." The man stopped mid sentence as he came to eye contact with him. He ruffled his raven hair in shock as he took of his sunglasses. "Dipper?" Dipper stared intently at the police officer as realization hit him.

"Well I'll be..." Dipper trailed off as he stared at the raven haired. "Robbie?!"

"I haven't seen you in ten years! I didn't even recognize you!" Robbie stated as he stared at his trench coat and tattoos. "When the hell did you get tattoos?"

"Story for another time." Dipper chuckled before continuing. "When did you become a cop?" Dipper asked changing the subject.

"Tambry insisted and besides I love my job. I never knew how much fun it actually was catching teenagers and taking them home to their parents." Robbie smiled mischievously.

"Wow, you changed a lot and if my detective skills aren't fooling me, I'd say you and Tambry got married?" Dipper asked with a smile.

"A detective, hey?" Robbie chuckled as he shook his head. "What gave me away?" He asked innocently.

"The wedding ring." Dipper stated obviously. Robbie nodded with a grin still clear on his face. "Care to explain why you stopped me?" Dipper asked as he quirked his eyebrow.

"Just a per-caution. The North-Wests went missing and I'm unfortunately on the case." Robbie stated in irritation. Dippers eyes widened in worry.

"Pacifica as well?" He asked hastily. Robbie shook his head.

"No it's her parents. She might not be on good terms with them at all these days, but they're her parents, kid." Robbie stated. Dipper nodded in understanding as a bit of relief washed over him.

"Well I'll be on my way then. I have work here I have to do and I'm guessing it has to do with what you just told me." Dipper sighed as he faved his steering wheel.

"Sure. I'll see you around, kid. It was nice to see you." Robbie stated with a smile.

"You too, man. Send Tambry my regards and congratulations. You deserve someone special." Dipper smiled.

"Thanks kid." Robbie stated as he walked off.

I frowned as soon as Robbie left. I was worried about Pacifica now. I knew she had it rough with her parents, but I can't imagine what she was going through. I should probably stop by her sometime. She could be a witness and a lead. I should probably catch up with everyone first before I headed to the company where I was meeting my client. I know it's unprofessional in a way, but I'm not a stick in the mud. I haven't seen my friends in a while, so this was an exception.

Dipper started his car again and pointed it in the direction of The Corduroy lumber mill. Excitement coursed through his veins as he thought about his old friends. He would finally see all of them for the first time in a very long time.

Tell me what you guys think alright? In the series Bill got erased from Stan's mind, but in this fanfic, somehow he managed to clung to the world and this is where he returns it's going to be a few chapters before he comes back, but that's practically the climax. Until next time...
