A/N: I don't own supernatural, I just own Emma. I know bummer right? If I did Sam would be my sister's and Dean would be mine. Castiel is younger than Emma and Emma is younger than Michael, but older than the rest.

Summary: Emma has a destiny, but what is it? To make the destiny of others come true. Why does Castiel look ashamed to have her around, and how does he even know her? Pairings: Castiel/dean and Sammy/OC.

Emma walked to the door, and scanned it, and behind it. She thinks she found what she was looking for, but couldn't be sure, as she hasn't seen Castiel since he pulled Dean Winchester out the pit. She knocked on the motel room door once, then fell into a bloody heap on the doormat.

To say that Sam had been surprise was an understatement, as he pulled the girl into the room and put her on the bed. He called Dean's cell and waited as it rang.

"Dean," said his brother's voice.

"Dean, it's Sam. We have trouble and Cas might be able to help."

"I am on my way with Cas."

After that, all Sam heard was the ring tone. He put his phone down and started cleaning The girls cuts and making sure they were not bad.

He had to wait thirty minutes for Dean and Cas, all the while taking in the girl. Half her back was cut open and bleeding badly, small cuts on her arms, like she cut herself, on her hands, and on her face. Sam was surprised that she could even make it this far away from wherever this happens. Besides the cuts and bruises, she looked like an angel, not a real one like Cas, but like someone else. He didn't feel this way since Jess or Ruby. Her hair looked actually like Anna's did. He felt as if he could be happy with her forever, if it were only true. Sam actually checked around outside and notice a trail of blood appear out of nowhere and up the their door. As he was about to check closer, Dean pulled up with Cas in the passenger's seat.

"What is the big news, Sam," asked Cas, as Dean got out the car.

"A girl knocked on the door once and when I opened it she was on the ground in a bloody mess."

"Do you think it was a demon?"

"No I don't Dean. She seems to have half of her back cut deeply. Maybe a demon did it to her," Sam looked at Cas, who started to walk to the room, "Can you help her Cas?"

"I'll see."

They walked into the room and Cas immediately went to Sam's bed, and to the girl.

"Good news is she will be fine," said Cas, as he looked over her.

"Bad news?"

"Bad news, Dean, is that she is an angel, with only one wing. The other was cut off."

"Lucifer," Sam asked as Cas made no movement to answer him, or even that he heard him. He was trying to wake the angel up.

She opened her eyes a little, and looked at Cas, who was still trying to get him to answer her.

"Emma, we need to know who did this to you. Can you answer me?"

"Yes, but I have to make it fast, I need to find my brother, he is known as Castiel. I need to tell him God is missing, Michael is missing, and Lucifer is missing. More demons are escaping from Hell and a powerful one named Lillith came into Heaven and killed most of the angels. Lillith cut off my wing, I can't go back to Heaven. None of this is going to my plan, everything is messing up."

"Emma, Lillith is gone, dead. Sam and Dean made sure of that. There is no way she could have done this. Where is Michael?"

Emma was awake enough to look around, and saw Sam and Dean standing back, silently, "Lillith didn't die though Cas, she went to the center of hell, the most painful part of hell. She escaped once Lucifer went missing, apparently he is in the Garden of Eden. No one can find God. Michael is not on Earth, in the Garden of Eden, in Hell, or in Heaven. Heck I am the Angel of Destiny, not an angel finder."

Dean got out of his shock enough to say, "so who's body are you in then?"

"She is in her own, Dean. A fallen angel needs a vessel, except Michael and Lucifer, as they need one no matter what. Emma, as a smaller angel of the lord, doesn't need one if she is not fallen. If I were not fallen I would be in my own body too."

"Is there anyway to actually destroy Lillith and not send her back to Hell," Sam asked Emma.

"There is one way too, but your brother won't like it."

"Emma," Cas warned, "Don't put this on him."

"Cas, if he does this then it ends the war between our brothers. Luce will be a good angel again, like he was before giving Eve the apple. He didn't even know that this would all happen. If he does this then we can get Lillith and all the demons into Hell and destroy Hell itself. It would get rid of his thirst also."

"What are you guys talking about," Dean asked before muttering under his breathe "stupid angels and their confusing talk."

A/N: Let me know what you think. I was planning on it being one-shot but I have more ideas.
