AN: Well... this gained a plot. Before this was just a thing fuelled by a conversation me and my friend had shared. Now there is a plot. Anyway, thank' for reading, hope you enjoy this chapter.

Sam

When I got back Sienna was awake and talking to Kayla and Cas.

"Where's Dean?" I asked as I dumped the bag on the nearest bed. Kayla looked up and smiled at me.

"He's been in the bathroom for ages." Kayla said as I walked over and ruffled her hair.

"I'll get him out in a sec. How you feeling?" I asked Sienna as she yawned.

"Like I really need to sleep. I'm fine, really." she added as I gave her the, you're not making me think you're better look.

"Whatever, I'm gonna get Dean outta the bathroom."

"I have a better idea." Sienna said with a grin. She then started to chant and I heard the lock on the door click.

"Did you really just do that?"

"Yep."

"Do it Sam, I kinda wanna hear him scream like a little girl again." Kayla added with a grin. I walked over to the door and kicked it. Dean screamed on the other side and quickly wrapped the shower curtain around him.

"Come on Dean, all of us need to shower." I said as I turned back to the girls who were laughing, Cas was looking at them like they they were being inappropriate. I laughed as Dean reached for a towel and slipped.

"I thought I locked the door." he said as he walked past me and pulled the girls door closed.

"You had. Sienna unlocked it." I replied as I opened the girls door slightly to let them go into the bathroom. Dean turned and glared as Sienna dived into the bathroom.

"Why would you do that?" he asked.

"You were taking ages. Besides, I'm covered in sweat, blood, paint chips, cement dust, the lot. I need a shower." she replied.

"And we wanted to hear you scream again." Kayla added as she closed the door.

Another three months with them and stuff started to change. We'd noticed something was happening with the demons during the last couple of months. Sienna had been more and more tense and Kayla had gotten better and better at noticing things that I barely saw. Everything was confirmed one morning though.

"Guy's Cas is-" Sienna's voice died out and she stood up, the book she had been reading falling to the floor as I came in. "Jack."

"Jack? What are you doing here?" I asked as I stepped forwards. Something was wrong with the way he held himself. When I had met Jack he had been 12, and a fun loving kid. Either he had matured a lot in the time Sienna was gone or something was wrong.

"You're not Jack." S said as she reached for the blade in her pocket.

"Correct, I am Kushiel." another flap of wings and Cas had appeared next to Sienna.

"Who the hell is Kushiel?" she asked, her voice rising in volume. I was glad that the others had gone out to get food because otherwise they would have been woken up.

"Kushiel is an angel of the lord, they work as a punisher in hell." Cas said as I walked over to her and grabbed her arm. I was slightly too late as she freed her arm and grabbed Kushiel by the lapels. She forced him to the wall.

"What the hell are you doing in my brother?"

"You wouldn't let me use you, he would. He wanted to see his sister on her birthday." Sienna shook her head.

"You're damn right I wouldn't let you use me, I struggle to control my power anyway, give me angel powers an I may as well die. But I will happily let you use me if you get out of my brother."

"I cant accept that as you giving me permission."

"Get the hell out of him!" she yelled as Cas and I grabbed her and pulled her back. Kushiel flew backwards and struggled against the force pinning them to the wall. "Get out of him, now." she seethed her voice dropping to a low whisper. I had never seen her this angry before.

"Why are you here, Kushiel?" Cas asked, Jack's eyes turned to him before he spoke.

"There is a war between the demons, Castiel. They are split into two forces, those who stand with Crowley and those who stand with one of Lilith's underlings. We need Crowley to win, but it looks like it is going the other way at the moment."

"So you want us to do, what?" I asked as Sienna raised them off the floor.

"We want you to help him and destroy the other side."

"So you want us to play soldiers. I don't think so." Sienna said as Jack started to gasp.

"You're starting to suffocate him." Kushiel said. She immediately let go and relaxed as the door opened. Kayla and Dean walked in and looked at what had happened.

"Anyone going to tell us what we missed?" Dean asked as he put the bags on the table.

"Kushiel has taken a vessel, the vessel being Jack." Cas said as I let go of Sienna who walked past the angel and closed the door before leaning on it. Kayla walked over to her friend and stood in front of her.

"You okay?" she asked quietly. Sienna glared at her.

"Do you really think that I'm okay?"

"No, I think you're pissed and rightfully so." Kayla smiled, I couldn't help but smile.

"What do you want?" Dean asked. Kushiel sighed and ran a hand through Jack's hair, the action was awkward.

"There is a war between the demons, those siding with Crowley and those not, we want Crowley to win. It doesn't look like he will though." Kushiel said, Jack's voice cracking slightly.

"So what? You want us to do your dirty work again?" Dean asked.

"I am afraid so Winchester."

Sienna walked over and grabbed her brother, pulling out a chair at the table and sitting him down.

"We'll do it, only because it means there will be less people hurt by demons. But you have to get out of my brother."

"I can't, if I do I will blind all of you, you included Sienna."

"Hold up, we are not doing this." Dean said pulling her back.

"I'm sorry, this coming from the kids whose mother was killed my a demon, and then their father was killed by the same one. I don't want my family to end up like that, it's bad enough we're all split up. I don't wan any of us dead." she said, shrugging out of his hand and glaring at him.

"We killed that bastard years ago. What you're suggesting is killing every demon that doesn't side with Crowley." I said.

"Crowley is keeping hell in check better the Lucifer ever was." Kushiel chipped in from the seat.

"If hell rebels even more demons will jump out and we may lose control of the pit. Lucifer might be freed. Do we really want another apocalypse?" Kayla said as she walked over.

"No, but this isn't like last time."

"How? This is almost exactly like last time." I asked, Dean glared at me.

"Kushiel, will you take Jack home if I let you use me as your host?"

"You are not doing that, you said yourself you'll die." I said, pulling her back. She glared at me and turned around to face us all.

"If I don't do this, Jack will die. He is 13 years old. He has no hunting experience and as far as I'm aware, angels tend to have a habit of blowing up. Or getting stabbed. Or tortured. Or straight up killed. I don't want him dead. I want him home and leading a nice, happy life." she said as she took a breath.

The room had fallen quiet. I didn't know what to say. She had a point though. Angels did seem to have a habit of getting killed.

"It's my choice guys. If it helps with the demon stuff that's been happening lately then I'll happily make it."

"You sure?" Kayla asked. She nodded and turned back around to Jack.

"I grant you permission to use me as your host." she said. Jack nodded his head and raised his hand before pressing it against her head.

"Close your eyes." he said. I did and a bright light appeared just after. I heard Sienna let out a gasp then the lights in the room flickered.

"You can open them now." she said, her voice not quite hers. I opened mine and saw Jack staring up at Sienna. She smiled slightly before touching his forehead and disappearing.

"Where did she go?" Dean asked.

"Kushiel was holding up his end of the bargain. He was taking Jack home." Cas said. She returned and got off the table.

"We should go, there is a group of demons nearby holding a group of people hostage." she said before doubling over. "No! Close your eyes."

I grabbed Kayla and turned her to face my chest before closing my own eyes. A light appeared and stayed for a while before vanishing. I opened my eyes and let Kayla go as Sienna fell to the floor.

"Find someone else. I know you all have secondary vessels." she said as she propped herself up on her elbows and looked around the room. I walked over and went to help her up but Dean got there first.

"You just used an angel to get your brother home." Dean said with a smile.

"Yeah, your point?" she asked as she stood up and grabbed her jacket from the chair she had left it on last night.

"Well done."

"Where are the demons that he was talking about?" Kayla asked. I had been wondering the same thing.

"Nearby, they took over the town hall I think." she said as she pulled her jacket on. I nodded and grabbed mine.

"I take it we don't get to eat first." Dean said before shrugging and chucking me the keys to the room. "Lets go."

I wasn't a long walk, we'd passed the town hall on the way back from the hunt that had been a bust. Sienna and I went in first, her silver dagger in her hand and my gun ready. Dean and Kayla were behind us, Kayla was also using the dagger we had bought her. I reached into my pocket as we opened the door and pressed play on the recorder we had picked up.

The exorcism played and all the demons inside turned to face us. They hissed, a trait that I had never really noticed before, and jumped at us. Sienna was ready and raised her hands. They hit an invisible barrier and were propelled back to the walls. With them out of the way I could see the people they had taken hostage, sat in a line crying silently. A woman stood in front of them. She turned and smiled as the exorcism finished and the other demons let go in wafts of black smoke.

"Well, if it isn't the Winchesters and their pet British girls."

"Go to hell." I said as I stepped forwards. She frowned and waved her hand lazily, then I was against a wall.

"Been there, done that, didn't like it that much, kinda boring." she replied. Dean walked past Sienna who had dropped her hands and stood in front of them.

"Oh, is the big brother getting protective of the two sluts?" she asked. Dean aimed his gun at her and pulled the trigger as she waved her hand again sending Sienna and Kayla sideways. Dean looked behind him before charging at her. She laughed and Dean stopped in his tracks. She walked towards him and pressed her hand against his chest. He fell backwards and I strained against the force keeping me back.

"Leave him alone."

"Oh, now why would I do that? My boss wants him, you as well. But she never said in one piece. So I can do whatever I want to you, I think I might have some fun." she replied with a smile as she drew her arm back and punched Dean in the face.

"No!" I yelled.

"Oh, be quiet." she said, turning to me and holding her hand up in my direction. I gagged as she made one of my organs fail.

"Sammy!" Dean yelled, unable to do much else. She drew her hand back and hit him again, leaving her hand on his face. I don't know what she did but he gagged.

"Leave him alone." Sienna and Kayla yelled. She turned and I heard Kayla suck in a partial breath before she coughed. Sienna struggled against the force that was pressing against all of us and closed her eyes. I turned back to look at Dean as she hit him again.

"Leave him alone!" I yelled.

"Do you want me to stop the other lung?" she asked. Ah, so that's why it was hard to breathe. Someone screamed, one of the hostages I assumed, as I struggled to breathe. The weight of our situation finally hit me, Dean was being beat up by a demon whose boss wanted us, I had one lung, Sienna seemed to have shut down, and Kayla was only hurting herself struggling against the force and whatever the demon had done to her.

The sound of Dean being hit again filled my ears as Sienna stopped chanting suddenly. I didn't understand any of what she had said, I had no idea if she had stopped or if she had been forced to.

"I said leave him alone." Sienna said, her voice closer now, no longer on the opposite wall. I forced my eyes open and watched as she grabbed the demon and kicked her legs out from under her. The demon glared up at her from where she had fallen on the floor and the hostages took a collective breath. The demon clicked her fingers and then Sienna was gone with a bang. It took a moment to process what had happened.

Sienna had been killed.

The blood that now covered all of us said that loud and clear.

"You're all going to pay for that. But you especially, Dean." they said before turning towards me and raising an eyebrow. "What are you looking at, shouldn't you be gagging by now? I mean, you have stage 4 cancer now, it's in your remaining lung, and there's nothing that can be done for it." she said as I started to cough and gag.

"Leave him alone." Dean said, his voice cracking.

"Okay." she said before turning to Kayla and walking slowly with a smile,

"Touch her and I will skin you." I said in between coughs. She turned and looked at me before laughing and raising her hand. I heard my leg snap before the pain flared, I almost blacked out. I gritted my teeth.

"Oh I am shaking in my boots." she said before turning back to Dean and kicking him. "To think that the Winchesters, so feared in demon circles, would be so easy to manipulate." she said as she raised a hand to Dean's face and then pulled it down his chest. He flinched at the touch. Then he started to cough and gag, when he stopped he levelled a glare at her.

"I was tortured for 30 by Alistair in hell. It's gonna take more to break me." he said before spitting the blood he had gained in his mouth at her.

She smiled and turned back to me.

"I guess the only way to truly hurt you is through these guys. I've already gotten rid of one, she got in the way, the boss won't mind. I think I'll see how much little Sammy can take before he brakes."

Why hadn't Cas shown up yet? Why hadn't he killed this bitch yet?

"It's a shame I don't get to play with that angel of yours, but that would risk the entire thing." she said before walking over to me and running a hand up my chest.

"Go to hell."

"Already said. How does it feel with one lung?"

"It feels great." I said before I coughed.

"Are you sure about that? Here, let me help with that." she said. I gasped as a deep cut formed under her finger as she dragged it down. She smiled as the cut reached from my collarbones to my stomach. "Does that make it feel any better?"

"Oh, so much." I replied tilting my head backwards unintentionally, my head lolling to the side as she punched my stomach. It felt like a shock wave going through me. I could practically feel the blood cells bursting under the force.

"That was for the sarcasm." she replied, her voice growing hazy. I heard Dean yell something as the world started to go black.

I passed out.
