Sorry if the formatting is crap, I'm doing this all on a phone, so. I't hard to tell what I'm doing. I guess this story is a two shot. I'll upload the second little bit by sunday.

So. Cool. Have a good one!

Lydia slowly walked towards the door, her hand shakily reached for the knob. She put her hand down, closed her eyes, and took a deep breath.
"You're his anchor." Deaton's words rang through her head. "So, bring him back."
She exhaled and gained her composure. Again, she reached for the doorknob, slowly turning it, tensing as the door squeaked, she bit her lip and pushed the door open enough to slide through. "S-Stiles?" She whispered. She cleared her throat. "Stiles?" She said more confidently, straightening her back.
"Lydia?" Stiles said coming out from behind a corner and slowly walking towards her.

Stiles was lightly hitting his head against the door of the locker that he was trapped in. "Let me out." he hopelessly mumbled between shaky, grief stricken breaths. He wiped a tear away and continued hitting his head, lightly on the door, when he heard her. "Stiles?" He barely heard it, but he did hear it. "Stiles?" the voice came again.
"No no no no." He whispered. Fiddling with the lock inside. The next word he heard filled him with despair.
"Lydia?"
That was enough to send Stiles over the edge, he pounded on the door with all his might, kicking it as hard as he could. "Get out of here." He shouted, wishing she could hear him. "Lydia. Leave! Please!" He shouted hopelessly and continued battering the locker door, determined to save her.
_

"Lydia. Help me." He said.
"Is it really you?" She asked him.
"I-I don't know where I am. What happened?" He questioned. But, there was a darkness in his eyes. Lydia didn't know how, but she could tell that something was off.
"You're not Stiles."
"Lydia, I am. It's me."
"Don't lie to me. I know my friend, and as much as you try to act like him, you- you can't be him." Lydia said, stumbling over words. The Nogitsune suddenly laughed.
"Maybe you are as smart as Stiles seems to think you are." He said smiling, circling her like a vulture.
"I'm not afraid of you." Lydia said.
"You're right, Lydia." He sneered. "You're terrified." He said leering in her face. "You don't know how to save him, and that terrifies you." He smirked. "You know, you're the one person Stiles has begged me not to touch. I mean, he doesn't want me to hurt the others. But you. You in particular..." He trailed off. "It honestly, has taken all of my self control not to come running to you and kill you. To get rid of his anchor." He emphasized the last word.
Lydia looked down, trying to figure out what to do. Deaton hadn't exactly told her how she could help bring Stiles back, just that, somehow, she could. "Stiles, I-" She started, but was promptly cut off.
"He can't hear you Lydia." The Nogitsune shouted suddenly. "Why can't you understand that? Stiles isn't here. It's just you, and me. And I'm afraid that you have gotten yourself into quite a mess."
"I-I" Lydia started, struggling for words. And for once in her life, none came.
The Nogitsune laughed again. "Oh, this is too good. Let me just guess. You came here all alone, right? Because you thought that, what's the phrase? Coup de foudre, you actually thought that would work? Love at first sight?" He laughed again. "Oh Lydia. How wrong you are." He reached into his pocket, and pulled out a silver switchblade, the handle fit perfectly in his hand.
"Stiles. Don't. You're stronger than he is." Lydia said, eyeing the blade as he flicked it open. "Please."
"So, uh, do you want a head start? Or should I just kill you right now?"
Lydia knew the Nogitsune was faster than she was, but she just needed to get far enough to scream. With that thought, she turned on the ball of her foot and began to run. But, the Nogitsune tackled her almost as soon as she began running. He roughly flipped her onto her back, and laid his body ontop of her as she struggled. With one hand planted on the ground, he put all of his weight onto her, her hands pinned between them. Lydia took a deep breath getting ready to scream. Before she could let it out, the Nogitsune pressed his lips against hers, Lydia tensed, then fought even harder to get him off of her. He pulled away from the kiss. "You held your breath." He smirked as he shifted his weight off of her.
She felt her chance and jerked her body away from him in a desperate attempt to free herself but something cold slid between her ribs. The sensation was odd, wrong, an invasion. The Nogitsune sat up, still sitting atop her. It was then she felt the warmth as it pulsed through her chest and stomach, a burning liquid.
Lydia looked down to her rib cage, as she feared, she saw the handle of the knife sticking out, the blade angling upwards. She could hardly breathe, and when she did blood bubbled around the knife. "Stiles." She gasped. The Nogitsune grasped the handle and turned it slightly causing her to cry out in pain, her eyes began watering. The taste of blood arose in her mouth. "Help." she whispered.
_

"Lydia!" Stiles cried out. The locker door was barely budging. "Don't you dare touch her!" He screamed. He heard his own laughter. He wasn't sure if he was laughing at him or at Lydia. Either way it just fueled Stiles' anger. He paused to catch his breath and to listen to the conversation.
"Stiles, I-" Lydia said.
"He can't hear you. Why can't you understand that?" he heard him yell. It sickened him to hear his own voice yell at her that way. He wished he could help, but he was the monster here.
"I can hear you." he sobbed. He hit the locker once in frustration. "Lydia. Please, get out." he whispered.
"-You came here all alone, right? Because you thought that, what's the phrase? Coup de foudre-"
"Coup de foudre?" Stiles mouthed.
"Love at first sight." The reply came. "Oh Lydia, how wrong you are."
Stiles angryily wiped tears from his eyes and kicked the door once more. "Stiles. Don't. You're stronger than this."
"No no no. Lydia, Lyd- what's happening!" He shouted. And once again started beating against the door.
"Stiles." He heard her, he could practically hear the pain in her voice.
His loneliness, sorrow, and fear left his body, and he was filled with a desprate rage. "Get. Away. From. Her." He yelled, each time kicking the locker.
Light spilled through the the bottom of the locker, the metal jarred out of place.

"He's not going to help you, Lydia." The Nogitsune spat out. "Why do you keep trying to talk to him. You're wasting your strength. He's dead." He grabbed the knife forcing it forward. Lydia cried out in pain, turning her head to the side she spat out blood.
"You're wrong." She choked out. He stood suddenly, relieving the pressure from where he had been sitting on her. This action brought on a new wave of pain, once again she tried not to choke on blood. "Stiles!" She cried.
"You and Scott, and everyone, you realize, the only way to get rid of me, is to kill me, right?" He said pacing next to her. "And doing that would kill him as well. See. That's why he was the obvious choice. Sheriff's son, best friends with a werewolf. No one can touch us." He said smiling. "So, you're going to die for nothing. And I will continue wreaking hav-" he grabbed his forhead and stumbled a bit. He shook his head, looked down at his hands, then over to Lydia.
_

Stiles almost laughed as dust danced in light around his feet. The corner of the locker was buldging out, he continued to kick it, each time the metal bending a little more. He didn't know what would happen when the locker door broke open, all he could see was the familiar view of the boys locker room, but he knew he wasn't really there. Would the Nogitsune leave? He'd still have his Frontotemporal Dementia to deal with, and that thought alone almost threw him into a panic attack, ready to give up again.
Once again, Lydia's cry pulled him from his musings. He was so close, and as far as he could tell, he was the only one who could possibly help whatever was happening to her.
"-you're going to die for nothing." He heard the Nogitsune say.
"One. Two. Three!" Stiles threw his body at the door with all his might and locker door finally gave way. Stiles felt his body fly through the air, hit the ground, but then he found himself standing.
_

Feeling dizzy, Stiles shook his head, trying to clear his thoughts. He didn't feel right, like he could collapse at any moment. He looked down at his hands, to his surprise they were covered in blood. He quickly scanned his body for a possible source. He looked over his surroundings before his eyes landed on Lydia, a pool of blood forming around her. "Lydia!" He yelled. His mouth went dry, which he didn't think was possible. He ran towards her, but, he didn't get very far before falling over. He got up on his hands and knees, he slowly crawled over to her, wishing he would go faster, but, he knew that if he lost consciousness he would be even less help. Stiles gagged as he got closer to the blood, he cringed as the it soaked through his jeans.
"Hey, hey Lydia." He said gently stroking her face. "Lydia, please wake up. Please don't- don't be dead." He gasped. "Lydia I don't know where we are. An- and, I just- Lydia. Please." Sobs racked his body. "I don't know what to do." He cried quietly. He felt her neck for a pluse. It was faint but there. He looked at the knife, he slowly put his hand around the handle. "I am so sorry." He said as he blinked the tears from his eyes. Stiles pulled the knife as gently as he could.
Lydia coughed, and blood tricked out of her mouth. "Stiles." She strained.
"Lydia, Lydia it's me." He said placing his hand gently on the side of her face.
"No." She pleaded. "Just let him go."
"Lyd, it is me. C'mon." Stiles pleaded with her, but her eyes closed. "Lydia no no no. God, please." He cried. His eyes teared up, and he was beginning to feel dizzy again. He moved away from her. He reached into his pocket, "Thank you thank you thank you." He breathed, and pulled his cell phone out of his pocket. With his hands shaking, he hit number 3 on his speed dial. The phone rang.
"Sc-Scott?" He stammered. The line was silent. "Scott. Please."
"Stiles? Is that really you?"
Stiles breathed a shaking sigh of relief. "Yeah, it's, it's bad, Scott. Lydia is, she's dying. And and I don't think- I can't. I don't know where we are." He said, breathing quickly.
"Okay, Stiles. We're coming, just hold on. Tell me wha-" Scott had been saying, but Stiles hearing went fuzzy.
"Scott. I-" Stiles managed to get out before his world went dark.
