How did I get in Gravity Falls?

Kidnapped- Again

It's 5 am and I can't sleep.... Wow I have the weirdest luck. So what am I gonna do? IM GONNA WRITE! then I'll probably proof read it when I'm not 75% asleep.
--------Amanda's POV---------
I woke up in the same room I had been lock in last night. This place is so strange. I wonder where Will went. That's a good nickname for William- Will. It sounds a lot like Bill though and frankly-
*KNOCK KNOCK*
I sat up and looked at the door- who was awake? Demons aren't usually awake at this time. I grabbed the door handle.

"Ha-ha... Very funny William." I chuckled, then opened the door to find a sac. And me being shoved into it. It Definitely wasn't William...
I tried to scream but I couldn't, I clawed at the sac trying to get free but it was a high quality sac... That sounds funny but it's true. I looked outside a small hole that was at least as big as my pointer finger finger to see that the person who ha just kidnapped me...

He wasn't tall, wasn't very strong- due to him dragging the sac that I am in, and he was definitely young, At least a year or two younger then me. Then I came to a conclusion... I know this person!
(((Any Wild Guesses Who It Is?!?! So usually I would be mean and end the chapter there. But I'm on a 'No Cliffhanger' promise soooo-)))

"D-Dipper?" I shrieked. The person dropped the sac and walked up to the opening. He helped me out of the sac and put a candle to his face.
It was Dipper...

I sighed in relief. "Dipper!" I yelled, hugging him. "You have no idea how happy I am to see you." I mumbled.

"Demons can be hard to live with Im sure." He responded, hugging me back.

"You have no idea..." I mumbled.

"Well you sure have changed a lot." He said pointing to my outfit. I was still wearing all black from my escape attempt.

"Yeah I guess I have." I laughed. He laughed along with me.

Then I realized something...

"But how did you get here- what's with the sac?!" I shrieked. At that second- Dipper stepped out of the hug and an evil grin formed on his face, he grew 2 feet taller and his hair turned yellow- his pine tree hat disappearing. William...

"William you jerk!" I yelled at him while he laughed. He is driving me crazy!

~~~~~~~~~~~~~~~~~~~~
You didn't think I was gonna let her escape that easily did you? Okay- expect a chapter on Sunday- A long chapter!

Well- now it's 6am I spent an hour writing this. Now I'm awake so- YAY!

So now I wanna take a vote.
