And this is where the climax begins...I think. You'll just have to read on to find out.

      Whiteness covered everything again. Necrozma had taken over him again? No it wasn't full control, only half. That somehow relived Gladion. At least he wouldn't have to betray (y/n) in front of her.

         "I pity you, Gladion." he heard Necrozma say. It was odd hearing Necrozma say such words.

      "That's the first time you've actually used my name. What do you want from me this time," Gladion said. The background shifted and gave him that usual headache that he was now used to. He found himself in his room back at Alola again.

      "It's time for you to die. By the end of tomorrow, I will have taken all of your life force without you even knowing it. Unfortunately for you, you will have no such chance to tell your friends goodbye. You must have noticed that time flies by much faster here. Why don't you listen and find out what's going on right now."

      Gladion's vision went black and he could feel himself lying on what felt like (y/n)'s bed. She must have brought him back to her apartment.

          "Let them go!" Gladion heard. It was (y/n) that spoke and she seemed to be in trouble.

      "Only if you agree to come with me. I will spare these two but the boy will have to come as well. He has connections with one of my associates." It was Lysandre. Just hearing his voice made Gladion want to get up and punch him.

         "I won't just let you take Gladion. You'll have to get through me and my pokémon first. Otherwise you can forget it!" (y/n) snapped.

     Lysandre laughed and said, "If you insist." Gladion returned to the blank infinite whiteness inside of his head somewhere, or was this Necrozma's mind. Necrozma appeared in front of him but before Gladion could say anything, the usual chains attatched to his wrist and the chain around his neck was tighter than usual.

     It barely allowed him to breath. This was how Necrozma controlled him. Gladion could now see where he was and hear everything with no problem but he could not speak and he didn't control his actions.

         Necrozma was in control so Necrozma got up and used his arm to choke (y/n) from behind. She didn't see the attack coming and was completely unprepared for it. Once she lost consciousness, he dropped her to the ground.

        "I was wondering when you'd show up," Lysandre said addressing Necrozma rather than Gladion.

        "I appear when I want to," Necrozma said. The pokémon materialized behind Gladion in his miniature form.

        "That's new," was the only desponse Lysandre gave. He was unphased by mini Necrozma.

      "We've got what we came here for. Take the boy and girl with us and put them in a cell. We don't need them to notify any authorities. As for the power source, you carry it, Necrozma," Lysandre said. Clemont and Bonnie were being tied up and Gladion used whatever power he had left to fight Necrozma but he failed.

      Necrozma picked (y/n) up just like Gladion would have done if she'd fallen asleep on his couch back in Alola. It tore him apart to know that Necrozma was purposely taunting him but he soon found a little bit of confort from it.

      (Y/n) had the bad habit of clinging to things in her sleep. Even when she was unconscious she would do this, so when she snuggled a bit closer to Gladion, even if he was being controlled by Necrozma, he could still feel the warmth that she brought to him.

          It was as if she was somehow telking him things would be okay. He found himself focusing on her touch as Necrozma followed Lysandre and the others to Team Flare's second hideout.

Timeskip! Brought to you by Eun because ninetailed foxes are awesome!

     Gladion refocused on his surroundings once again. (Y/n) had been taken from him by Lysandre and as much he wanted to say, " Get your filthy hands off of her!" he couldn't, but he could think it as much as he wished to.

      Lysandre attached her to some sort of machine and hooked wires to her head and arms. What scared Gladion the most was that the machine had some of the same qualities as the electronic torture chair that he had to endure just days ago.

        "I'll just sit back and watch as your plan fails and wait until you then give me what is mine. Good ridance to you," Necrozma said to Lysandre.

      Lysandre just scoffed at him and continied with what he was doing. When Necrozma turned to leave, Gladion got his first glimpse of the actual area. They had only been in the center of an underground area that had a door and a window at the very top of the room above the door. He could faintly see lab equipment and computers through the three glassed window row.

      Along the walls of the room were pokémon, two for each type, and they were tied to the wall and also had wires linked from them to the machine that (y/n) was hooked to. Necrozma smirked which was something Gladion didn't do much.

      "You can tell that this plan is going to fail already can't you. Even if he does manage to draw power from her, he will only get a small fraction of it. I will have (y/n)'s power. Only I have the power to get what is mine back!" Necrozma said inside of Gladion's head. Necrozma went through the door and walked up all of the stairs that led to the laboratory.

      Once inside, Necrozma found a spot right next to the window to sit so that he could see what happened. When Lysandre appeared in the lab as well, with (y/n)'s bag in hand, Necrozma called him over to where he was.

        "Do me a favor would you. Tie the boy to this here chair and make sure you tie him down tightly. He will surely enjoy the view. Oh and if you will, put her pokémon near him so they can hear the screams as well," Necrozma said.

      "I'm not a huge fan of torture just so you know. The only reason I am going to do this is so you can watch me take her power. You'll see. My plan won't fail."

         As soon as Lysandre had done as Necrozma had asked and walked to the main control desk, he got a call on his holocaster. Gladion hadn't known what a holocaster was until Clemont had used one and told him what it was. It was one of the admins that had called.

        "Sir, there's been a fire here at the main base. The girl and boy that we were keeping hostage escaped in the evacuation. We weren't able to save much." She said the bad news so calmly that it scared Gladion a little. What was wrong with these people? Lysandre responded by hanging up the call.

      "That place is no longer needed anyway. My plan will succeed and I will make this world new." He went back to work as he seated himself at the main controls desk and flipped a switch. Nothing happened.

         "Why isn't this working," Lysandre said furiously as he stood and turned towards the group of admins behind him that were operating miniature desks.

      "Our controls have all frozen over, we can't turn anything on," one of them said. "Mine are frozen too," said another. "Duh! He just said that!" said yet another.

         "Enough!" Lysandre ordered. "Go outside and use your pokémon to unfreeze the main generator. Some of you stay inside and do the same while I turn on the backup generator." Lysandre was much calmer this time when he spoke.

      The man's sudden mood changes made Gladion feel even more unsafe even though he was still being possessed and controlled by Necrozma at the time. After a couple of hours everyone returned to their places and Necrozma let Gladion resume control of himself. Lysandre said nothing as he flicked the same switch and the machine turned on.

      After a couple of more switch flicks, screaming rang through the air. (Y/n)'s screaming and it was loud and filled with agony. Gladion couldn't help but respond by trying his best to break free of the tightly tied ropes that held him in place.

         "Relax, Gladion. If you'd just cooperated the first time, you wouldn't have to witness this," Lysandre said.

      "You bastard! Let me go!" Gladion shouted at him. He continued to pull at the tight ropes even as the red marks formed on his skin. The screams still went through the air and they made Gladion hurt inside. It was like he was in the torture room again but this time it was (y/n)'s screams that he heard. He didn't stop pulling and tugging at the ropes. He could handle anymore of this.

         "Let me go!" he yelled this time. It sounded more like a plea. Then there was one last scream from (y/n) and she became still. The electric shocks still went through her body yet she didn't move and Gladion feared the worst. Had she just died?
