You understand (Bill X Dipper)

Unexpected visitor

We got to the mystery shack and it was almost dark. Grunckle Stan told us that we had different rooms now because we needed privacy. Although I would miss talking to Mabel at night, I would be able to write in the journals Grunckle Ford got me for my birthday last year. I carried my bag up the stairs and to the room I would be staying in. When I finally got the room I put my stuff down next to mine bed. I looked around the room and saw a triangle window that had many memories. I zoned out for a second looking around in fear. I snapped out of it and started to unpack my bag.
Mabel's POV
It's good to be back in Gravity Falls. I smiled and unpacked my stuff by starting with my sweaters. I then started to put some posters up onto the wall. I was sad that Dipper had a different room but, at least I could stay up and talk to Candy and Grenda for as long as I wanted. I looked at a picture of when me and Dipper were 12. I smiled and giggled at our silly faces.
Bill's POV
I need to get revenge on the pines family. They defeated me and I am now stuck in this miserable body.I was walking around in the woods thinking of a plan and I looked at the Mystery Shack and the window into Dippers room."Pine tree you will regret coming back to Gravity Falls".I started to grin that stretched from ear to ear showing my sharp teeth.
Dippers POV
I looked at the triangle window and got a blanket from inside a closet and hung the blanket over the window so I didn't have to look at the creepy thing. As I hung the blanket I shivered and jumped back. I brushed it off and grabbed my own journal,a pen, and a jacket. I ran down the stairs to the kitchen."Grunckle Stan, I'm going for a walk." Dipper said."Be back by dinner we are having Stan cakes for dinner  since you guys came back today!"I nodded and ran out the door with my stuff.Grunckle Ford was in the basement researching like he always did.It was about 6:03 and Grunckle Stan told me to be back by 7 so I had enough time to explore. As soon as I got into the forest I got this weird uncomfortable feeling like I had got in my nightmares I have been having. I heard a twig break and I turned around saying,"Is anyone there?".There was no response.So, I turned back around and saw this handsome looking man with yellow and black hair,a triangle eye patch,yellow eyes, and small top hat, a bow tie , a white dress shirt,a yellow tail coat with a brick pattern and a triangle on it,black dress pants,and black shoes.

Not my picture btw 😊
He was stunning.As soon as another second went by I realized he was from my dreams.How was he? "Thanks for the compliment Pine Tree"The man said smirking revealing his sharp teeth."Bill!?"Dipper screeched.Bill started laughing hysterically.He's insane!.Dipper started to run back but Bill went in front of him."Where are you going, and so fast Pine tree?"Bill said.I was in complete shock ,this was almost like one of my nightmares. "Well? Aren't you going to say anything?" Bill asked. My eyes widened. "Same old Pine tree, scared and weak"he said smiling and putting his cane on dippers chest."What do you want you Dorito!?"Dipper screamed."Finally!Something out of that stupid mouth of yours... I want to make a deal with you. "Bill smirked."Now why would I do that?"Dipper said."Well..."Bill said as he swung his cane and circled Dipper on the floor. "Since you defeated me I am stuck in this body and I want out in return for protection from anything that may harm your family. K? Now roll them sleeves up we're about to make a deal" he said grinning evilly. I thought about the deal.Was it worth it?Was he planning revenge? I mean it's Bill. (As Dipper was thinking, Bill was planning revenge and the plan was going perfectly ) "Fine!"I yelled.Bill held out his hand and we shook hands. Was this a mistake? I thought as I was shaking his hand.Bill had disappeared which made me happy. Its time to head back.
Third person POV

Dipper had just gotten back to the shack when everyone was sitting at the table, eating Stan cakes."Hey bro bro"Mabel said,"Hey kid" Stan and Ford said. Dipper sat down, and the pines family all started to laugh and tell story's. "This meal is called Pines family dinner!"Mabel yelled .The whole family laughed and ate there meal.

Mean while upstairs.....

Thump!"OW!I need to work on the teleporting with this human body thing."Bill said.Bill heard the Pines family laughing and talking downstairs."Great Pine tree is busy. That is just great ._."Bill huffed quietly. Bill communicated with Dipper through the mind. "I think I'm done with dinner.I'm going to go upstairs" Dipper said quickly running up the stairs." What do you want Bill!?Aren't you supposed to be doing evil things?"Dipper sighed."Pine tree the whole part of the deal was to keep you and your family safe. In order for me to do that for you I have to keep my eye on you at all times.So,I will be staying here from now on."Bill said with a grin.(Now I regret the deal)-Dipper thought to himself."Don't have second thoughts Pine tree you will like having me here. Remember how you reacted to seeing me for the first time?"Bill said. Dipper blushed and covered his cheeks.(How can he fall in love with someone evil?)-Bill thought."Fine.Sleep on the extra bed in here."Dipper said as he walked out and down to the kitchen."My plan is working out perfectly."Bill said with an evil grin on his face.
