Dean

I sat down, for the first time in a while, happy. Then I realised we hadn't tested her and I got up. Kayla looked over at me with a raised eyebrow.

"What are you doing?" she asked as she stood up slowly.

"We haven't tested her." I replied. She realised then and got up quickly, pulling her dagger from the sheath and putting it on the table.

"I'll get the holy water." she said before disappearing. There were only a few things that we needed to test her, silver, iron, salt, and of course holy water. Kayla came back with a flask that still had a few drips on it.

"Got it." she said. I nodded and we walked towards Sienna's room. Sam met us halfway and stared at us before realising what we were doing. He looked like he had just realised how much of an idiot he is.

"You don't think she's a demon do you?"

"I don't know, that's the problem Sam." I replied as I walked up to her door, knocking quickly.

"What?" she replied as I opened the door. She rolled over in the bed and looked at me tired.

"We need to test you." Kayla said as Sienna sat up.

"Alright, lets get this over with." she replied. I stepped forwards and pressed the silver blade against her arm. It did nothing, not a shapeshifter. Kayla threw some salt at her, and she frowned at it. No effect. I offered her the flask of holy water and she hesitated in taking it from me.

Sienna had few tells as to when she was in pain. Her eyes would close, her jaw would clench, and the muscle nearest the pain would tighten. She did all of them as she took the flask from me. I reached for my gun as she took a breath before undoing the cap and taking a sip.

She coughed and dropped the flask, the remainder of the water emptying on the floor as I pulled the gun on her. She held her hands up in reaction, but I was stuck on her eyes.

They were a dark grey, not black, or white, or red. Not normal demon eyes.

"The hell?" slipped out before I realised it.

"Yeah." she said slowly as she recovered. "That's a thing."

"What are you?" Sam asked as he lowered his gun.

"I'm not quite sure myself. As far as I know, I was too close to becoming a demon to be completely unaffected by it." she replied.

"So you're what, half demon?"

"I guess." she said as she picked up the flask, only to hiss as she came in contact with it.

"Anything else we should know?"

"From what Crowley told me it'll pass over time, the longer I spend up here."

"Anything else?" I asked as she stood up.

"Yeah, but it's better I show you than tell you."

"Guys what- oh hi again Sienna." Charlie said as she stopped at the door. I turned and put my gun again.

"We need more room." she said before leaving the room and starting back to the library. We followed with Charlie joining us. Cas was already in the library when we got there. Sienna stopped in the middle and gestured for us to stop at the door.

"When I left you all, creating a simple devils trap with magic would almost wipe me completely out. Well, hell changed that." she said before gesturing for Cas to come over to us. He did so slowly as she pressed her hands together.

"Cover your ears." she said before separating her hands. A bright ball of light emerged and hovered in the air before she flicked her wrists. It expanded, a shock wave hitting the wall and shattering the shelves. The light grew brighter and larger, I realised it was an explosion.

She brought her hands back together and the shelves put themselves back together and the ball got smaller before disappearing. I dropped my hands to my sides and looked at her.

"Holy shit." I heard Kayla say to my right as Sienna dropped her hands.

"That was a contained explosion." Sam said as I gained the ability to speak again.

"Son of a bitch." I said, not completely aware I had said it aloud.

"Woah."

"Well. You certainly got stronger." I heard Cas say as we all slowly walked towards her.

"Is this a side effect of hell, of nearly becoming a demon?" I asked, still not sure whether I should trust her or not. She shrugged and rubbed her wrist.

"I don't know. I think it's all mine, you know. Like I had this all, but it was locked away. Not the demon obviously though." she replied.

"When they said you were a witch I assumed like Rowena, but you did that without a spell. Rowena always uses spells." Charlie said as she stepped cautiously closer, not that I blamed her for the caution.

"I haven't used the spell for creating fire in a while. I know two things, and I can do them without saying the spell aloud. Pyrokenisis, and Telekinesis." she said. I knew that was right.

"Anything else she has to use a spell."

"Yeah, now, can I go to sleep? I think we've all had a long journey." Sienna said as she walked back over to us.

"That sounds like a plan." I said. We all went our separate ways and retired for the night.

I gave up trying to at around midnight. I pulled on my robe and walked to the library, surely this couldn't be the first time this has happened, surely there had to be something in the lore. I pushed open the door and saw Kayla sat at one of the tables.

"Looking for something?" I asked as I walked over and looked at the books spread out in front of her.

"Obviously." she replied as she glanced up at me. "What are you doing up?"

"Couldn't sleep. You?"

"Me nor-" she looked like she wanted to continue but a scream interrupted her. I looked over at her as she got up before starting down the hall.

"Well that's not good." I said as another slightly muffled scream came from down the hall.

"It's Sienna." Kayla said as she ran towards Sienna's room. I followed but was distracted as another scream sounded.

"Sammy?" I turned to look for his room. I started towards it, he hadn't screamed in his sleep since Lucifer, if he had then.

"Dean, she won't wake up." Kayla called. I turned, that was worrying.

"The hell is happening?"

"I don't know, help me wake her up." she said before walking back inside her friends room. Another scream sounded, a mix of Sam's and Charlie's.

"Do you think it's her?" I asked.

"Don't know, worth a shot." she said before shaking Sienna hard. I winced at how hard, but she still didn't wake up. Instead she let out a high scream and writhed under Kayla, who was forced to let go.

"Let me." I said as I walked inside and took Kayla's place on the bed. I shook Sienna harder than Kayla had, but I stopped when her eyes opened.

"I will rip your soul out and tear your meatsuit limb from limb." she said, her voice hoarse. I turned to look at Kayla who was watching on wide eyed.

"She aint waking up-" a surge went past then I was unconscious.

I woke up and tried to move, only to find chains with hooks dug into my skin wrapped around my waist. Hell. I tried to move my head, only to find sharp points digging into my neck. Fuck. I couldn't even feel my arms, I assumed they were tied up against the wall I could see in the corner of my eye.

From what I could see the room was white, white walls, white floor, white door. There was a light above me, one of those shitty ones you find in asylum video games. It swang slightly, the light making it hard to look at anything as it shone on the walls. The door opened and a demon stepped in.

"You're very loud, you've woken up a few others from there torturing." he said. It wasn't Crowley, from the times I had seen him with her he felt like a father to her. I'm not sure what happened to her father, I hadn't met him.

"You know, I'm gonna make this worse for you." he said as he walked over, a large syringe in his hands. I flinched away, I realised that it wasn't me moving but Sienna. This wasn't a dream, or a nightmare, it was a memory.

"Go rot." she said before spitting a mouthful of blood at him. I was in her place, I was living her memory. The demon clicked his tongue and wiped the blood up, putting the hanky in the pocket of his white suit. What was with all the white?

"I think you know what this does." He said as he showed us the liquid before grabbing our hair and pulling it so our neck was exposed. I felt the liquid push inside my veins and I knew something was instantly wrong.

I looked up at the demon but instead I saw something else.

Sienna's father was sat at a table. He was an old fragile man, who was going bald. From the angle I was seeing this from I assumed Sienna was a kid when this happened.

"Dad?" Sienna sounded different as she walked forwards. Something was off with the scene, she seemed to sense it and reached for a necklace. Her father stood up turned to face her. She stepped back and I looked closer at his face.

We let out a muffled gasp.

It was peeling, like bad sunburn, and in spots you could see the skull underneath.

"Dad?"

"Your dad's long gone sweet heart." they said, there eyes turning black. The lighting changed and I saw Sienna's arm as she brought it forward. It was clean of any scars, so this was before college. The fire in her hand glowed brighter and she raised it level with the demon.

"Get out of him." she said as she brought the hand closer. The kid had balls.

"Now why would I do that?" the demon asked. Something changed and then the fire was on his clothes, crawling up his skin. The demon smoked out and went for her. It bounced off something and she fell to the floor.

She got up and walked over to her father.

"No. No! I didn't mean to- dad."

"See, you belong here. You have innocent blood on your hands."

"I will rip your soul out and tear your meatsuit limb from limb." I said, her voice sounding in the room. I flinched at the noise as it reverberated and came back louder.

The demon walked over and pulled out a knife. It was small, but the way the demon held it told of how sharp it was, as did the slight hiss. It was iron. He walked behind us, each stem sending a shiver down her spine and making me jump. The blade trailed down her spine before reaching the chains where he tugged hard.

The hooks dug deeper and a scream escaped my mouth.

"Ah ah ah, there will be none of that missy." the demon said from behind as the knife broke the skin on her back. I felt it as it ran over the bones of her spine, shredding her nerves. She screamed, her head lolling forwards onto the points of the collar. Her back was bleeding, her waist was bleeding, and her throat was bleeding. She sucked in a breath and forced her head off the spikes, biting back tears.

"Comhdail." she said. The knife clattered on the floor and a thunk sounded outside the room. The door opened a moment later and the same demon came in, a object I had never seen in his hand. Sienna shied away from it as he walked in, her breath quickening. He undid the buckles at the back, I felt like I had seen it somewhere, a museum maybe.

"Open your mouth." he said. Sienna growled at him as he got closer. He shrugged and pulled the chains again. She screamed. He jammed it into her mouth and quickly did the buckles up around her head. It was heavy and made of iron.

"Now you'll be quiet." he said as he pulled a whip from the air. He was going to whip her? "I believe your kind are familiar with this, though maybe you would prefer to be burnt alive, because that can be arranged." he said as the room heated up. She tried to stand as the room slowly caught on fire, I could feel her feet burning. She stood up and the demon tutted.

"Stay down." he said before kicking her. She fell, landing on her back, the hooks digging into her skin further. The metal fast heated up, the metal of the chains making it harder to breath as it heated up. The one around the head hurt more, her eyes were starting to close from the pain as a shadow walked into the room.

"Si-" I couldn't make out what they were saying, but it was clearly to Sienna. They were looking right at her. "Wake up." they said before clapping there hands.

I gasped and let out a groan as I reached my hand up to a bruise on my cheekbone. I looked around and noticed that I was on the floor of Sienna's room.

"The hell?" I asked as I rolled onto my stomach and got up slowly. Kayla was hunched on the other side of the bed. She woke up with a cough and then Sienna opened her eyes. She looked up at the ceiling, I wasn't sure she was awake until she turned to look at me.

"Oh gods." she said as she sat up. "I'm so sorry." I walked over and pulled her into a hug.

"Hey, hey it's okay." I said as I rubbed her back, letting her cry.

"What happened?" Kayla asked as Sienna rubbed her eyes.

"I don't know, I just went to sleep, then I could feel everyone else there. But I could do nothing."

"What the hell could it be?" I asked them. Kayla shrugged.

"I looked into the lore whilst you were out cold, nothing. Zip. Nada." she said as Sienna looked at the small pouch around her neck. She took it off and held it out to Kayla.

"What did you put in this?" she asked, her voice croaky from the crying and the screaming.

"Um- Datura- um"

"Which Datura?" Sienna asked.

"There's more than one type?" I asked.

"Yes."

"There is?" Kayla asked. Sienna turned to look at her.

"You put Inoxia in this didn't you, it's the only one I owned."

"Is that bad?"

"Yeah. You know labelling things would be useful." Kayla said.

"It causes nightmares. But seeing as I was already having them it amplified them." she said before getting up.

"I need to destroy this." she said as she walked out of her room. We followed her up the the door then she closed it on us. There was a loud bang then she opened the door again.

"All gone?" I asked.

"All gone." she replied shakily as we started back down the stairs. Sam was at the bottom of the stairs to meet us.

"What just happened?" he asked. He looked as bad as I felt, his hair stuck to his head with sweat, his lips bleeding, his nails chipped.

"The pouch I gave her, I had filled it with Datura, which on its own should have helped. However, Datura has an ugly cousin called Datura Inoxia which causes nightmare." Kayla said as we walked into the library.

"Huh, easy mistake."

"Yeah." Sienna conceded. "I should have labelled it better."

"What the hell was that?" I heard Charlie's voice as she walked out from the kitchen, a glass of water in her shaking hands.

"That, Charlie, was hell." I said. "Though I am still stuck on something. What was that thing he put around your head?" I asked. She flinched and cursed under her breath.

"It was a Witches Bridle. My kind, hell my family, have had them used against us for centuries."

"A witches bridle, hell has one of those?"

"They aren't exactly hard to find." she replied as she sat down.

"I am so sorry." I said.

"Not your fault Dean. I chose it."

"No one should have to chose 100 years of torture." Sam said. "Ever. That should never have been an option."
