I slightly opened my eyes not feeling Bill near me. I looked around and saw a clock: 9:32 a.m. Where is he? And why is everything white outside? I thought as I looked out the window. Then I remembered everything that happened a few hours ago: my family coming to our house, Mabel shooting on Bill, me transformed in a demon... It's still strange to think that she, my own sister would want to kill my lover only to have me back. Why can't she understand that I'm happy with him and that I don't want to be by her side? I laid again on my bed, tears streaming down my cheeks. I should have noticed sooner who she really is and what she has done. I'm such an idiot. I curled up in the bed, trying to calm myself down, not noticing a light glow coming from me. But why do I miss her? Why? Is it because she is my sister? I stood up, not wanting to think about that anymore and went to the kitchen/ living room. There I saw Bill... cooking?

"You know how to cook?" I said surprised.

"Yeah, but it's not my fault that this week you never let me come near the kitchen and that you always made everything. Now sit down and eat." He said as he put a plate of Pancakes on the table.

"Pancakes? Seriously?"

"Why not? I thought you like these. But if you want I can cook something else."

"No it's perfect Bill" and I stood up to kiss him, but as I came nearer I noticed that I was glowing. "Why am I glowing?" I panicked and I was engulfed by yellow flames.

"Dipper calm down. You must control your powers. Breath in and out and relax."

I tried to and after a little time the flames disappeared, but not the glow. "What was that?"

"Like I said your powers. I think it's because you're a new demon, you don't control them completely. We must train you." I sighed, feeling depressed. "Don't worry Pinetree, I'm the best teacher you could ever have" He said smirking. "Let's eat and then we can begin your training." We finished eating and we went outside of the house.

Bill snapped his fingers and a forest appeared before us. "Now let's begin" he said smirking. A shiver ran down my back.

~~~~~~Timeskip~~~~~~

After shooting some yellow fireballs for hours, I couldn't move anymore.

"Bill, please can we make a break?"

"Sure Pinetree, as soon as you can control your energy and stop you from glowing like a Christmas Tree."

"I'm not a Christmas tree" I muttered and tried to concentrate on my energy. I must try to imagine it and contain it inside my body. I don't want to glow like that! And I felt my energy returning to me. I felt way better than before and no more so exhausted. I did it! I finally did it!

"Great Pinetree! You earned yourself a little reward." And he came nearer to kiss me and as our lips were about to meet, a purple glow appeared. We had to part away and look at it.

"Oh a portal" Bill said and I saw a purple circle that seemed connected to another dimension... Is that the Nightmare Realm? And I felt a wave of power emanating from it. I tried to go nearer but Bill grabbed my hand, stopping me. I looked at him and then again to the portal seeing a purple square with tiny legs and arms and a floating top hat like Bill's coming out of it.

"Hello brother!" he greeted.

"Why are you here?" answered Bill and his eyes narrowed.

"Me? I'm just greeting my brother that I didn't see for years."

"Yeah, naturally you came to see me. And the truth?" Bill said with his eyes glowing.

"Okay, okay" he said lifting his tiny arms before him as a protection. "I came to see this new demon." He said pointing at me.

"Why?"

"I felt a great power emanating from him. Don't you think he would be even more powerful than you when you were in the nightmare realm? It's such a waste to let him here, he could be the most powerful demon that the universe has ever seen." Bill put me behind him at this words and spoke with an angry tone.

"Don't touch him. He will never make the same mistake I made all these years ago. I will make sure of that. Now go away and never come back."

"May I ask what is his name?"

"My name is Dipper" I said not really impressed by all this. I freed myself from Bill's grip and came nearer the square. "And yours?"

"I'm Tad Strange. I hope we will meet again, young demon. Maybe next time in the Nightmare Realm. I would be glad to help you there." He said smirking and winking (or I think he did with his one eye. Maybe is he only blinking?)

"No thanks, Tad. Now go away and like I said never come back. " Bill said his eyes flashing red and taking me away from Tad and the portal, back to our house. "Please Dipper, promise me you won't go there. I can't let you do the same mistake as me." He looked at me with pleading golden eyes and I tried to pat him on the back.

"I promise Bill. I will never go there." But this power wave felt great. Stop don't think about that Dipper! I scolded myself, trying to listen to Bill.

"In order to protect you from Tad, I need to teach you how to protect your mind like mine."

"It is because of that, that I can't read your thoughts?"

"Exactly! You're smart my little Pinetree." He hugged me and we went inside the house in the living room. There we sat down on the ground and he spoke again. "You need to concentrate on your mind. You must imagine some walls around it that will stop anyone from entering your mind. You must imagine them very strong and perfect because if they have a little crack, demons could slip through it and read your mind." I tried and he spoke again. "Good, it's almost perfect. You only need some more practice and they will be very strong."

"Thanks Bill for being such a great teacher" I smiled at him, trying to comfort him and make him forget the encounter with Tad. He smiled at me in return. "But do I need to do this every time I want to protect my mind?"

"No, with a little more practice it will stay without you even thinking about it. And now, let's eat dinner and go to sleep, I'm sure you're exhausted." Actually, I wasn't. The power of the Nightmare Realm must have energized me. It felt so great and good. No, I can't let myself think like that!

~~~~~~Meantime at the Shack~~~~~~

Mabel's POV:

I was the entire day locked up in our room, trying to think and relax on my bed. He is gone again. And it's my fault. Wait no it isn't. It is Bill's fault. Yeah, he is the responsible for everything! He stole Dipper away from me! And then I heard Grunkle Stan calling me.

"I come!" I shouted back. I went downstairs to the kitchen to see Grunkle Stand with Great Uncle Ford at the table with some food on it. I looked out the windows and saw it was already dark. I sat down not looking at them.

"Mabel... We both know you are really depressed since Dipper left like that, but maybe it was really his choice to go, maybe he wasn't under a spell." Ford said. I looked at him anger in my eyes.

"NO! It was an act! He is really under a spell, I'm sure of that." No, he isn't and I know that. But I need them to believe that so we can get him back. They looked at each other and Stand nodded.

"We could bring him back."

"How?"

"We could build the portal again and try to find them. I'm pretty sure they are in the Mindscape." Ford said. I smiled at him, acting as if my happiness and cheerfulness came back.

"We can do it! We can bring Dipper back!" I said almost like a slogan.

"But we will need some time to do it. Maybe 1 or 2 years." He muttered. Unfortunately for him, I heard.

"1 or 2 years? You can't do it faster?"

"Sorry sweetie, we can't..." Stan said. "But in the meantime, you could go to the college near here. You could live here with us, help us, and everything. We only need to advise your parents and it's done."

And then I will definitely kill this Dorito and this time Dipper won't be able to save him. And Dip Dop will be again by my side, like before and we could act like nothing happened. I will make him some sweaters, redecorate his part of the room with glitter and more pink fluffy stuff and it will be alright. I smiled at that.
