Apollo cabin and Apollo: Awwww, why?

Bill's P.o.V.

This was bad. Real bad. Really really really really bad.

    As you would think, I started on the wrong foot with Stanford, (Y/N)'s dad. If Stanley reopened the portal...he'd be able to get out of that futuristic universe! Meaning he'd hunt me down. Meaning he'd keep me away from (Y/N)! I don't even care about my plans...I need to make it up to him! I don't want to lose (Y/N)!

    "We need to go inside. I need to check the place," (Y/N) said. Before she could go out into the open, I grabbed her arm.

        "Have you lost your mind?! There are officers there! I'll just teleport us," I whisper-yelled. She just bowed her head down, a bit embarrassed.

        "I could've been invisible," she said before I teleported us inside the shack in her room. 

        "How come the officers didn't check your room?" I asked her.

        "Ehem, mister. You're with a daughter of magic. 'Course we have our ways!" she said as she made sure the door was locked. She checked the room if there was anything out of place. She seemed to find none.
        
        "Let's check the attic. I think they invaded that already," she said as she opened some kind of hatch and pressed in a code. "Never tell anyone about this. Actually, it's not really a bad secret, but...never mind." The wall we were facing suddenly opened and we went inside. Two torches suddenly appeared in (Y/N)'s hands, each with brightish darkish green flames (hey don't judge! They're magic, how can I tell?!). "Thanks Mom," (Y/N) silently said. "Let's go," she said louder this time.
        
        We walked through corridors and stuff. "Where do these corridors lead?" I asked her. Even I didn't know about it. She seemed to read my mind.
        
        "This secret passageway is under the whole town and lots more of places. You wouldn't be able to see it because it's protected with ancient magic. There used to be...something here that I'm not allowed to say. It's weird we didn't get lost," she said. We climbed a few flights of stairs and she leaned against a wall, ear flat on it.

        "It seems like they left the room," she said as she once more felt the wall and pressed a panel. "I don't even know how it still operates...just like what Hazel said." The wall parted and closed as we went through. (A/N: Clue: PJO Book 4)

        "Waddles! C'mere, you poor pig," she beckoned over to the pig. I looked around the room. It was the twins' room. Waddles oinked and scuttled over to (Y/N). "You need to stay here for a moment. Sorry," she told the pig who I am sure did not understand what she said. It went over to Sho-Mabel's bed and lay there. "Good pig," (Y/N) muttered. I looked out the window to find that the officers were leaving.

        "Hey, (Y/N), look at this," I said and she rushed over. I went to the side a bit so she could see better from the window. Even from our distance, I could smell her fragrant hair. 'Wait, Bill! What are you thinking of at this kind of time?!' I thought to myself.

        "BILL!" she shouted, which snapped me out of my thoughts. She was already at the door. "Uncle Stan won't like this, but I need to go to the portal. Schiiiiiiiiist. you're coming with me whether we all like it or not." She pulled the door open and we ran downstairs. She stopped in front of the machine. She did a spell and broke the whole thing, leading to narrow stairs.

        "Greeeeaaaat, no one will suspect a thing," I said mockingly as we went to the stairs. She rolled her eyes and did another spell, which fixed the whole thing as if nothing happened. 

        "You think I didn't know that?" she also said mockingly, punching my shoulder lightly. "We have a humanity to save!"

         We ran into the elevator and she looked at the symbols. "Hey Bill. You know Stan more than I do. What alchemy stuff do you think he'll choose?" she said as I looked at it. I punched in the four symbols that looked most appealing and the elevator door opened.

        "Nice work!" she high-fived me as the door closed. Good thing the ride was quick. It would have gone awkward. Just when we stepped out of the door, gravity failed. I caught her before she could hit the pipes above our heads.

        "Thanks," she said as it returned to normal. "I guess flying powers have perks." We ran to the desk and (Y/N) halted right in front of it.

        "What's wrong?" I asked her. 

        She sighed before speaking. "It's just that...well...the Pines hate you and all, and I'm here, a Pines, bringing you right in front of Dad's biggest discovery or invention. They might kill me and you," she gave a nervous laugh. "But anyway, its now or never."

        "Wait, how do you know so much about the portal?" I asked her.

        "Even when I was asleep for thirty years, I remembered everything Lady Hecaté told me," she said while looking at the two journals she laid out. She grunted. "I hope Uncle's got a photoco-" she stopped when we heard voices and quickly closed the journals. "Hide!" she whisper yelled.

        "I don't understand! Why would Mr. Pines have all this?" I heard Quest-Soos say.

        "It's just like that bunker in the woods," Dipper said. They got closer and closer to us. (Y/N) mouthed something like 'Let's show ourselves' or something. I also heard Sh- Mabel speak. So just the three of them. We went out of out hiding place. The three nearly screamed but (Y/N) silenced them with some technique. Oh, not technique. She just said 'it's us.' 

        "What are you two doing here?" Dipper asked suspiciously.

        "To stop this thing or whatevs, duh," (Y/N) said.

        "Why is William with you?" Mabel asked.

        "We just happened to be together when this ruckus began," I said. Dipper began looking around and gasped. We rushed over to him.

        "It can't be...it's impossible. Other two journals?! All this time, all this time, Stan had them!" he shouted angrily.

        "Man chill! I-just don't freak out and stuff! It'll make things more difficult!" (Y/N) said trying to calm him down. He kicked on of the metal cabinets in frustration.

        "Then why would he have those journals?!" Dipper shouted again.

        "Maybe he's the author!" Soos said.

        "Or maybe he stole them from the author! Maybe the reason he has all those fake I.D.s is because he is a master criminal, and this machine is his master plan!" Dipper theorized angrily. 

        "Oh boy," (Y/N) muttered. 'If Dipper turns against Stan, everything will turn out badly. This machine wasn't really created for bad intentions,' she told me telepathically. Dipper flipped through the pages of the three journals and stopped on the page of the codes. He shone a UV light over the combined pages. The three gasped, and (Y/N) shook her head vigorously, as if to imply that it was true, but not fully. They read the invisible ink and when they were done, they glanced at the timer.

        "It's the final countdown! Just like they always sung about!" Soos exclaimed.

        "The agents were right! We have to shut it down!" Dipper shouted and they ran inside. (Y/N) was frozen for a bit, then suddenly she looked at me.

        Then suddenly, realization dawned on (Y/N)'s face. "We can't let them shut it down! We have to stop them!" she shouted. Suddenly, the elevator door opened and Stanley came out. (Y/N) ran to his side.

        "WE NEED TO STOP THEM!" (Y/N) screamed. She grabbed my hand and ran behind Stan. Dipper was about to press the shut down button but luckily, Stan busted right in.

        "DON'T TOUCH THAT BUTTON!" he screamed. (Y/N) seemed like she was about to faint. Stan panted as the three stared at him.

        "Dipper, just back away from the button, please. Hear Stan out," (Y/N) said in her most soothing voice. Even Stan seemed surprise with (Y/N).

        "Yes...please don't press that shut down button. You gotta trust me!" Stan told Dipper.

        "And I should trust you why?! After you stole radioactive waste! After you lied to us all summer! I don't even know who you are?!" Dipper shouted at Stan. (Y/N) started to tear up.

        "I know this all seems nuts, but I need that machine to stay on. If you just let me explain-" he stopped speaking when his watch beeped.

        "Guys! BRACE YOURSELVES!" (Y/N) shouted at them. Everything started to float. (Y/N) 'swam' through the air, trying to reach the shut down button to close it. "Look out!" I shouted and she ducked just before a block hit her. She beamed at me and shouted ,"Thanks!"

        Everything turned into ruckus. We hit random places and even if I could float, losing gravity doesn't help. I saw Shooti-okay! Mabel's feet got stuck with a wire.

        "Mabel! Hurry! Shut it down!" Dipper ordered Mabel.
        "No!" Stanley dove to push Mabel away but Soos caught him. I tried to pull Soos away from Stan but failed. 'Man, the guy's strong,' I thought.

        "Dipper, don't!" (Y/N) screamed but Dipper had already joined Soos to stop Stan. "Mabel! Please don't! DON'T PUSH THE BUTTON!" I continued trying to free Stan while (Y/N) tried reaching for Mabel. Stan kept begging Mabel to not press it. Mabel started to cry and I even felt sorry for the kid. Her mind was probably messed up on who to trust.

        Just then, another anomaly happened and we were hit backwards, crashing at the far side of the room. Only Mabel was near the portal. She nearly pressed the button but Stan started talking. Dipper continued to tell her to shut it down. But then, nearly everything stopped when we heard (Y/N) cry.

        "Mabel, please. How would y-you feel if you had a chance to see your dad again...but the decision is not on your hands. It's on the person who needs to decide whether or not they close the portal or not...Mabel! Hear me out as a sister! I'm begging you! Trade it for my life or anything, but I need that portal going."

10 seconds left.
        
        "Mabel, that thing can destroy the universe! It'll kill us all!" Dipper shouted.

        "Look into my eyes Mabel. Do you really think I'm a bad guy?" Stan asked her. (Y/N) cried, which was unlike her. Always fierce and happy.

        "Mabel, please! I'll give my life or everything! My identity, or whatever! You gotta keep the portal running! Please trust Stan!" (Y/N) shouted as her tears continued to flow.

        "Grunkle Stan, I trust you," Mabel said as she let go of the shut down button.

        "Mabel, are you crazy?! We're all gonna-"

        1

        Screams filled the air. Pure whiteness filled the air for a few moments, while the others floated around blindly. Even for a millennia old demon, it was a bit much to comprehend. Then it all ended and we all fell on the floor. I sat up and rubbed my head slightly. (Y/N) was already running towards me. I guess ADHD had its perks.

        "You alright, Bill?" she asked in a hushed voice. I nodded. Just then, a man walked out of the portal. He's hand fit the hand in the journal. He picked it up and put it in his coat pocket.

        "No...he's...back?" I asked myself, trying to check if I was still intact.

        "Dad..." (Y/N) whispered.

        "Wha- who is that?" Dipper asked.

        "The author of the journals," Stanley said as the guy took of his goggles. "My brother." (Pretend Soos never fainted)

        The others' mouths were hanging open. (Y/N) stood up quickly, and so did Stan.

        "Long time no see, Dad!" (Y/N) said enthusiastically even if tears were still brimming her eyes. The others looked even more shocked. Then even more shocked when Stanford took the gun on his back and pointed it directly at (Y/N), making her looked shocked.

How heart-warming. His first words to her were: "I sense Cipher."
