After the events at the party, I went back home to finish some homework. Something in the back of my mind was telling me to go back to the chemistry classroom and look at the atomic numbers on the board.

When I got to the school, I noticed Stile's Jeep in one of the parking spots. He wasn't in or around the vehicle so I went inside. The hallways were empty as I made my way to the classroom. I opened the door to see Stiles at the front of the class, writing the same atomic numbers that were on the board.

"Stiles." I spoke, and he turned around to face me. Dropping the chalk onto the floor, he looked back to the board in disbelief.

"Olivia, I wrote this. I don't remember when or why, but I wrote this." He whimpered. I walked to his side and examined the board. He was right, the handwriting was identical.

"You have no memory of it?" I questioned, picking the chalk off of the floor. He shook his head and we were interrupted by my phone ringing. I took it from my pocket and hit answer.

"Scott? What's up? Stiles is with me by the way." I put the phone on speaker so Stiles could hear the conversation.

"The masked things you saw tonight? They're a group of Japanese spirits called the Oni. They are looking for their leader, somebody possessed by an evil trickster spirit called the Nogitsune...and Olivia, they only target supernatural creatures." Scott spoke through the phone, resulting in Stiles giving me a confused look.

"But Scott, I'm not a supernatural creature." I replied. He has to be wrong about that part. I'm not supernatural. I'm not like them.

"Maybe it's something like Lydia? She didn't have her abilities until she was bitten." Stiles joined in the conversation as my hands started to shake.

"No, don't even make me think about that." I interjected, rubbing my forehead with my freehand. Stiles bit his lip, looking at the phone in my hand.

"I don't know, I don't get it either." Scott said. We finished up the phone call, and I hung up. Stiles gave me the same sympathetic look he gave me earlier. I let out a sigh and tucked my phone back into my pocket.

"I don't understand it though, you're not supernatural." Stiles said, checking his phone quickly. I shifted my weight onto my left foot and shook my head.

"I don't either."

After talking with Stiles in the chemistry classroom for around a half an hour, I told him I had to leave. Believe me, I didn't want to go, but it was getting late.

When I reached the exit of the hallway, I got a sudden feeling in the pit of my stomach. Something was telling me not to leave, to stay and find Stiles because he was in danger. I turned back around and searched the halls for him.

When I started heading towards the history hallway, I heard a familiar snarling noise. I peeked around a corner to see where the sounds were coming from and saw Stiles surrounded by the five Oni.

Part of me wanted to yell and scream for him to run away, but I knew he couldn't get away now. One of the masked spirits grabbed onto his neck like it had to me and looked into his eyes. It's eyes glowed extremely bright through the mask, and I waited for Stiles to drop to the ground.

Instead, Stiles grabbed the Oni's arm and pulled it away from him. I let out an almost inaudible gasp, watching as the spirit disintegrated into nothing. Stiles hand was in a tight fist, and when he released it a firefly fell out onto the checkered floor.

Oh my god. It's him. Stiles is the Nogitsune.

I stood there like an idiot, not knowing what to do. Should I say something? Should I run away? The five, now four, Oni disappeared into the shadows. Stiles stood still, staring into the wall in front of him.

"Stiles?" I immediately regretted speaking after the words left my mouth, and he turned around. I took in a breath, stepping around the corner to face him. He didn't look any different. He looked like normal, funny, sarcastic Stiles.

"Are you okay?" I questioned, keeping my distance away from him. I didn't sense any difference in him, but if what Scott says is true then the Nogitsune is a trickster.

"Yeah. Yeah, I'm fine." He replied, acting completely normal. I nodded slightly, slipping my thumbs into my back pockets.

"Alright, well I'm going to go now. See you tomorrow." I mumbled before shuffling out of the school.

Apparently nobody thought about calling me to let me know was going on last night, so I didn't find out that Stiles got into trouble sleep walking until this morning. He thought he was stuck in a trap and that his leg was bleeding, when in reality he was in the woods completely unharmed.

Today, Stiles is going in for an MRI. All the symptoms he has are similar to what his mother died from, frontotemporal dementia. When I heard that, I broke down crying. I'm the only one who knows what's really wrong with him, and I don't know what to do. I feel like the only people I can tell are Deaton and Derek. They both have experience and might know how to handle it.

I decided to miss school for the day and go visit Stiles in the hospital. I figured I could keep him company while he goes through the whole ordeal. On my way to his room in the hospital, I bumped into Derek.

"Derek. You have no idea how glad I am to see you. I need to talk to you about something really important." I told him, pulling him off to the side of the hallway.

"Okay, but make it quick." He replied, pulling at his leather jacket. I nodded, pursing my lips in hesitation.

"Um, so you see here's the thing. I think Stiles is the Nogitsune." I whispered, averting my eyes from his gaze. He let out a chuckle.

"You think Stiles...skinny, defenseless, Stiles..is the Nogitsune?" He was clearly not taking me serious, so I went on to explain what happened the previous night.

"Think about it. He sleep walks and doesn't remember what he's doing. He feels like he's dreaming. It's like he doesn't know what's going on ninety percent of the time." I pleaded my case to Derek, starting to walk towards the room Stiles was in. Derek nodded, said something about figuring it out, and then walked away.

"Stiles." I said, leaning against the doorway to the hospital room he was resting in. His eyes opened and a smile spread across his face.
