23- The Final Confrontation

This is it!!!!!
---------------------------------------------------------------------------------------
Y/n's P.O.V
I threw open the doors to the main part of the pyramid castle to find Bill standing there, almost as if he were waiting for us. He was in his human form, but I knew I could find a way to get him to change into a triangle.
"Bill!" My voice was sharp and loud, almost sounding like I had barked out his name. The menacing character whipped around and smirked at the three of us.
"Well, well, well, if it isn't Pine Tree, Shooting Star, and my own little minion, Petals. I'm assuming you're here for this." Bill snapped his fingers and pointed to the cage. I followed the line of his fingers to see my mother struggling against the bars, screaming something inaudible.
"Mom! Don't worry, mom, we're going to get you out of here!" She looked at me, but it seemed like she almost didn't know who I was. I wasn't sure what to think.
"We? Oh, no, no, no, no. This fight is between you and me, Petals." Bill snapped his fingers and the world around us froze, with the exception on Bill and myself. Fear ripped through me as I looked at the frozen figures of Dipper and Mabel. They had devised their own plans on how they were going to free my mother and defeat Bill, and now all of that was thrown out the window. I would have to improvise the whole fight.
"You're right, Bill, this is between you and me. You're the one who messed up my life ever since we made that deal, and now I'm going to take you down once and for all."
"Do you think defeating me will get rid of what I've done to you? You're stuck with this for the rest of your lie, Petals." He seemed amused at my ignorance.
"Then this will be revenge for everything that's happened all these years." I lunged at him and tackled him to the ground, pinning him beneath me. I freed one arm and punched him square in the face, but it seemed to do almost nothing. He smirked at me and used his abilities to immobilize me, then lift me up, leaving me open for him to attack. He punched me in the gut, then slapped me across the face multiple times, then swept under my legs, knocking me to the floor once again. Bill stood over me and cackled, thinking he had won.
"Oh, sweet, naïeve Petals. You fell into my trap right from the start."
"What are you talking about?" I gasped out.
"You saw the way Pine Tree would have died a few days ago! You could have stopped it without having to become one of us! You're so stupid! Now, even if you defeat me, you'll get taken away, too."
"W-what?" I was confused and terrified.
"You're part Dream Demon. Everything associated with that realm will get sucked back in, and that includes you!" Although I was afraid of being separated from Dipper, Mabel, and my mother, I needed to defeat Bill and make sure he was no longer a threat.
"That doesn't matter. I'll enjoy defeating you." I used my own powers to free myself, then blast Bill back against the wall. He seemed shocked that I had figured out how to use my powers. I lifted up some fallen rocks and shot them at Bill. He was able to dodge two of them, but the third one nailed him straight in the chest. He coughed, seeming weak, and I seized the opportunity to charge at him. I punched and kicked over and over again, and eventually, Bill fell to the ground, unable to move. Remembering what I needed to do, I ran over to the gun and pulled it out of its case. Using my powers, I changed him back into his triangle form, then aimed the gun so it was perfectly lined up. He looked at me, stunned.
"Are you really going to do this, Petals?" I smirked at him. "You're just going to get dragged into the Nightmare Realm."
"If I'm going to Hell, I might as well drag you to Hell with me." I blasted him, and with a final scream, he exploded into millions of pieces. The world unfroze, but the wind began picking up, and I knew what was happening. Dipper and Mabel looked at me and started to race over to me, but I stopped them by holding out my hand.
"Mabel, go free my mother from the cage." Mabel looked at me in shock for a moment, then did as I said. Dipper looked at me with shimmering eyes.
"(Y/n), what's wrong?" I sighed and tried to smile at him.
"I'm getting sucked into the Nightmare Realm because I'm part Dream Demon."
"What? No, you can't..." I could feel the pull calling me, but I tried to hold on as long as I could. I walked up to Dipper and cupped his cheek.
"I have to." He took my hand and held it in his. "Dipper, I love you so much. You changed my life. You accepted me here, and helped me with everything." Without saying another word, Dipper kissed me on the lips, hard and passionately. I pushed away from him as I began to evaporate into the realm. I said one last thing before I was transported into the realm.
"There's always a way to get back a Dream Demon."

DON'T WORRY! THIS ISN'T THE END! YOU AND DIPPER WILL HAVE A HAPPY ENDING!
