Bill's POV
I watched pine tree and shooting as I was invisible to them. I knew pine tree could sense me since he got chills being sent down his spine. I smirked as I became visible to only pine tree. Shooting star was stuffing her self full with pancakes. As I became visible to only pine tree he nearly spit out the water he was drinking. Shooting star cooked her head in a confused manner and said "What's wrong bro-bro?" He stared at me and back at shooting star and shook his head and said "Oh... its nothing." He let out a fake chuckle. Shooting star eyed him and said in an unbelieving manner "suuuure." She slowly took another bite of her pancakes. Pine tree laughed and ate some of his pancakes. He stared at me as I mouthed "Soon." I put hovered in front of her inched from her face and pine tree growled a little.
Dipper's POV
I saw bill hover in front of Mabel inches from her face smirking. That little freak! I stared at him and took one more bite of my pancakes and stood up putting my dishes in the sink. "I'll be outside Mabel, I need some... Fresh air." She looked at me and nodded "Okay" She Said as she finished the last bit of her pancakes. I walked outside making sure bill was following me. I walked into the forest. Deep into the forest. Bill was still following me. Good. I stopped and looked at him and said "Leave my sister alone!" He smirked and landed onto the ground and said "I don't think so." His smirk widened. He spoke again "And probably not the brightest idea of leaving your sister by her self when your all the way out here." My face all the sudden went pale.
Bill's POV
Time to go say hi to shooting star! I snapped my fingers and teleported to the mystery Shack. I walked in and shooting star had just walked up the steps into her room. I smirked and walked up the steps and opened her door a little bit and peaked my head inside. Shooting star was laying on her bed drawing random things. She didn't seem to notice me. I walked in and covered her eyes. She laughed and said "Dipper, is that you?" I laughed a little and said "Wrong answer shooting star." She didn't speak.
