A Pinetree and a Triangle.... A Dipper X Reader X Bill Cipher Fan-fiction.

Fighting the beast...

YOUR POV
Ow, ow, everything hurts.. What in heck happened? You couldn't even move... You could hear someone. Was that Dipper? Oh, thank god. You'd never been more glad to hear anyone's voice. "... (Y/N), this is all my fault.. I'm so, so sorry! And now you're hurt, we're down here at the mercy of two demons, and I don't know what to do... And I never got to tell you that-well- I love you..." Whoah.. No wonder he always got so awkward! It all added up now! Wait- two demons? You heard footsteps and a second voice. "Wake up, (Y/N)! Fight it! I can't lose you! To me, you're more than a friend.. And- and well, I really like you. Demons aren't supposed to, but I won't deny it any more." Wait, what? All your life you've never had a second glance, now the two guys you think are pretty cute both just said they love you? Wow!! Wait- so this was why they kept snapping at each other? Oh.. You tried again to move, and managed to open your eyes again. Everything was dark, except the glowing from Bills flaming hand and Dippers torch. "H-hey, dorks." You smiled weakly. "(Y/N)! You're okay!" Dipper yelled. "Haha, yeah.. And for the record, grappling hook to the face is really painful." You laughed at the 'told you so' look Dipper gave Mabel, then winced at your shoulder. "Guys.. There's something down here, isn't there? And we need to stop it."

BILL POV
"And we need to stop it." What?! My admiration for (Y/N) just grew even more. She's just been beaten and bruised, cut and torn at, and yet she still wants to fight a monster! "No way. You couldn't even move a second ago. We're out of here." She used a bit of metal to haul herself into a sitting position. "No. And don't even think about making me- I'll come right back down here again!" She had the stubborn look on her face. There's no way I'll change her mind. Powers can't do everything. "At least let us help you." I summoned some bandages and antiseptic, and Dipper and Mabel helped me put it on her, despite her muttering that she was 'fine, really guys. You don't need to.' I wandered off to look at the door. Now I was closer, I noticed some writing. 'Experiment #239- summoning and containing a Feli demon. Oh no... The door was open. "Pinetree, did you open this?! Where's the demon?" Dipper looked up, shocked. "I forgot for a moment! I wouldn't worry, though. I gave it the hardest puzzle in.." He broke off as he saw the newly finished puzzle off to the side of the chamber. "This dimension.." A huge weight landed on my shoulders and I yelled, summoning my magic. Time to fight.

MABEL POV
I saw a huge.. Cat? Land on Bill. He tried to fight it off with his blue fire, and Dipper threw rocks at it to distract it from its prey. "You escaped once! I will kill you for that! You and this whole dimension!" It hissed. It was chasing Dipper now! What do I do? "Mabel! Help!" I grabbed my grappling hook and shot the creature in the side. It slowly turned and prowled towards me. Bill was knocked out, and Dipper, despite his best efforts, couldn't injure it. It leaped and I closed my eyes.. And heard a thud. Opening one eye, I saw that the huge beast had hit the floor, out cold. (Y/N) was stood, and I saw she had a hefty piece of metal. She smiled awkwardly. "Aim for the magic looking eye thingy. Usually works." I saw that she had jabbed it from the side, right in the large glowing eye in its forehead. "Is there a spell in there to banish it or something, Dipper?" My bro looked through the journal. "It can't die, but it says I can neutralise it as a threat.. Well, (Y/N) can, anyway. The one who defeats it becomes its master- or so the author wrote." (Y/N) limped over and looked at the page. Okay, so.. I need to chant this? Here goes...NOITATNACNI NOMED TEP YPEERC!" As we watched, the bright patterns on its black fur disappeared, and so did the third eye. It just looked like a huge panther- it was like, horse sized! I stroked its fur. "Looks like we got a kitty!"

(Finally, the whole tunnel thing done! Sorry it was so long!)
