I need you to stay... (BillDip)

Part one.

~~Dipper's POV~~

      He slowly walked in the thickened wooded area.  Walking to an opening, then sitting under a tree.  He opened up his journal and started reading.
"Hey Pine Tree!!" The boy heard that voice, the annoying yet attractive voice. 
Dipper quickly looked up.  Seeing the now human Bill. No longer his triangular form.  After making dirty amends with the demon he was somewhat trustable.
It's been years. So many years since I've seen him last. His eyes widen as he sees the tall sleek demon. "It's been years huh?" The demon human nodded and held a stance showing he had to use the restroom.
"You need to use the bathroom? " The 19 year old Dipper asked.  He nodded and the two walked to to the mystery shack. "Shhh. Grunkle Stan still hates you." He snuck him into the bathroom. He stood outside the door while the demon did his business.

~~Bill's POV~~
    He zipped his pants up and washed his hands. His new motto is to be a gentleman. He fixed his hat and bit his lip. He walked out. Seeing Stan, Dipper pulled him quickly to his room. "Woah Pine Tree! What's the rush!" He chuckles jokingly. He floats to sit on his bed.
"Why are you here anyway?" Dipper said obviously stressed. "I missed ya!" He responded happily. His smile bright. He then plays with a screaming head. He snaps his fingers and appears behind Dipper. He covers the boys eyes with his hands and whispers. "Missed me?~" he floats to the bed again and chuckles. He appears in random spots in the room. And he gets scolded by the boy. He stops then just sits in bed.
