I stared in horror, looking up at the archangel looming above me. "Seriously, guys, points for trying. Super impressed, but, uh... playtime's over." He flicked his wrist at me, and I went sailing in to the side of the house. Mary rushed over to me, making sure I was alright. I couldn't move, though. I couldn't stand. I recoiled in on myself, and felt as though someone was stabbing my stomach and shoulder. Mary tried to help me, but I shook my head.

"Run." I whispered, reaching a hand out to her. I could get her out of here, get her somewhere safe. It was all over now. Lucifer was on the wrong side of the Rift. It would close any second, and we had no other options.

But when I touched her, I couldn't force her to go anywhere, couldn't get her out of here. My power… It wasn't there. It didn't exist anymore. She saw what I was trying to do, and saw that it didn't work.

I watched as her jaw set, and she turned to face the Devil.

"Get away from them." She ordered, advancing forwards.

"Mary, no!" I shouted. She ignored me, though, and walked until she was face to face with Lucifer. He just smiled cocking his head to the side.

"I'm gonna guess your name is Mary, right?" He nodded. "Yeah, I've heard about you. You, uh, are certainly living up to the hype." She didn't say anything, just pulled something out of her pocket. Lucifer didn't notice, though. He kept talking. "Look, seriously, I just wanted to say thank you for everything. I owe ya, kid." He smiled, and I could finally see what Mary had behind her back.

Brass knuckles, enchanted with enochian.

She took another step forwards, past the brothers, and I watched as Sam put out a hand to stop her. "Mom, Mom, Mom." He shook his head, fear evident in his voice. He didn't see the knuckles. He just thought he was about to watch his mom die.

"I love you." She told them, her voice calm and clear. I let out another scream, feeling more bones break and more bullet wounds show up and my head… My head was killing me. But that scream, that was enough to get everyone's attention for a moment.

Everyone's except Mary's.

She swung hard, and I could hear her fist connect squarely with Lucifer's jaw. He took a few steps back as Sam rushed to my aide, trying to help me up. "Kylie, what's happening?" He asked. "What's wrong?"

"Cute." I heard Lucifer comment. "Is that all you got, mama?"

"It's the spell." I said. "It's almost done. It needed angelic grace. Sam… I couldn't ask Cas to do that. I gave it mine. And now…" I bit back another scream as I heard Mary punch again, feeling gashes in my arm start to open. "Sam, every time I healed myself or someone else… It's coming back."

Mary punched again and again and again, I could hear her. Sam looked between me and her, uncertain of what to do. Dean moved towards us, trying to pick me up and help me get away. Mary was buying us time.

"You need to teleport us out of here." Dean insisted. I shook my head.

"I can't." I cried. "I can't." I had to be here for the spell to finish, I had to have proximity. I could die and be fine, as long as I was close by, but if I teleported away? That would kill both me and the spell at this point if I even could muster up the juice to get out of here. All we could do was watch as Mary did exactly what she wanted to do - punch the Devil in the face.

Mary landed one more punch, one that would knock Lucifer in to the Rift. He dropped the angel blade, tripping on Castiel… Tripping on his body as he careened backwards towards the Rift.

She was doing it. Mary Winchester was punching the Devil in the face, and going to trap him forever.

I didn't see Lucifer's hand grabbing at her until it was too late to warn her. Dean tried, screaming for his mother, but it was too late. They both fell through, and I felt the last part of the spell finish itself.

The Rift closed without a single sound, leaving Mary Winchester and Lucifer trapped on the other side of it.

"Mom, Mom! No!" Dean and Sam were both shouting now, Dean running towards where the rift had been as Sam stayed with me, watching through watery eyes.

"Mary!" I screamed. It was useless, though.

They were on the other side, and we couldn't get to them.

"No!" Dean shouted, looking from where the Rift had been to Castiel. "No. No, no, no, no, no."

Sam looked up at something in the house, and looked back to me. "I'll be right back." He promised, rushing inside. I stayed where I was for maybe a second more before I started crawling back towards Castiel's body. Dean didn't see me until I was closer, and he didn't stop me. Instead he helped, lifting me up to put me next to Castiel. That was when he saw the extent of my injuries. I was broken and bleeding, blood pouring out of me from too many different wounds to fully count. I couldn't heal myself, not anymore. I was... I was dying. I could feel it.

"No." He shook his head. "Not you too." He begged.

I couldn't answer him. I couldn't stop crying. He layed me down gently next to Cas, and I did my best to curl towards the angel.

"I'll get some… some bandages from the house." He promised, looking around. "Where's Sam?"

"Inside." I croaked out, recoiling at another injury. I didn't even know where this one was, there were too many. Just that they hurt. They hurt so much. "Please, Dean. Let me die. It was supposed to be me." I shook my head, reaching to grasp as Castiel. My arm broke as I did, and I didn't even remember when or where or how my arm had ever broken. Maybe it was just… That my body couldn't take anymore. "It was supposed to be me." I still reached, with my arm fighting me every step of the way, until my hand was over his chest.

"No, no, you're… you're going to be fine." He promised. "I'll get you fixed up, just let me go get Sam and we'll… We'll drive you to a hospital and we'll fix you." He ran off then, towards the house. I just stayed where I was, one hand on his chest and the other reaching for my pocket. He couldn't be dead. No. This had to be the other him, there had to be an other him.

But as my free hand reached the stone, I felt it. I felt the ice and coldness emanating from it. Cas was… Was…

Was dead.

"No." I whispered, bowing my head in to his shoulder. "No Cas, no. I'm sorry. I'm so sorry, Cas. No, please. Please." I kept crying against him, letting go of the rock to instead reach for his hand. "I'm sorry, Cas." That's all I could say, all I repeated. I'm sorry. I'm sorry. Please. No. I'm sorry.

I heard a shot fire off, and a few seconds later a pulse that radiated within the house. I froze, uncertain of what was coming. There was only one thing that could do that, now. Only one thing that existed, and was able to fire off the kind of energy I felt.

I heard footsteps in the grass maybe minutes later, headed in my direction. I didn't move, I couldn't have if I wanted to. Instead I just waited.

If I was going to die, I was going to do it beside Castiel. The footsteps stopped right behind me, and just stayed there for a minute.

"Kill me." I dared the Nephilim. I didn't know what he'd done to Dean and Sam, and I couldn't care. "Do it. Please."

"No." He replied, his voice… Older than I expected, and surprisingly soft. "Father would not want me to."

So instead, I felt a hand press against my back, and I… I don't know.

I was out cold.
