"What should I do?" Dean said into his hands. Bobby put his hands on his shoulders and squeezed them for comfort.

"It'll be hard for her to hear but you should tell her and soon." Bobby sad sadly.

"She'll hate me." Dean argued.

Bobby smacked him on the back of his head "She will not you idjit. She'll be hurt if you don't tell her."

"I should go find Sam." Dean sighed getting to his feet.

"I'll handle Sam, you take care of your sister." Dean nodded.

Bobby listened to Dean's steps fade down the hall muttering to himself. "What a mess."

Bobby hated seeing his family so upset. His heart ached because he knew no matter what he would lose a son and the other two would loose a brother. Bobby wasn't angry with Dean, he knew exactly why he did it, those boys were inseparable. And little Kate was never far behind. When she was younger she hero worshiped her brothers, especially Dean. She was the one other person they would die to protect. Bobby often wondered wether or not Dean thought about how his death would make Katie feel when he made that deal. but still Bobby could understand how his mind turned one track with Sam dead. Dean was feeling the pain that Sam and Katie would soon feel in six short months. But Dean's grief was different. He was the oldest and felt as if he had failed them, Sam and Katie. Dean also didn't get the chance to say goodbye to Sam and Sam didn't get to say goodbye to him. Bobby didn't know if Dean's death would be harder or worse.

Ah well no use crying over it, Bobby thought with a sniff.

Dean opened the door slowly peeking inside. Her shut the door behind him as quietly at possible and tip toed to the bed where Katie was sleeping. He let out a small smile and pulled the covers up over her shoulders. He brushed a few hairs lightly off of her face and kissed her forehead softly. he backed up to sit on the chair in the corner of the room. He put his hand under his chin and watched her sleep.

I can't leave her here without me, Dean thought with guilt. He knew Sam would be there for her but he couldn't help thinking that he was going to abandon her. If he hadn't made the deal he would have held on to her so tight, not wanting to lose the only family he had left. But he could never regret making the deal even though it would cost him his life. His siblings meant everything to him and he hoped he meant everything to them. he couldn't live with himself knowing he didn't try anything to save Sammy. Now here he was worrying over his baby girl and arguing with Sammy.

Katie was smart and Dean knew she wouldn't try anything she couldn't handle but today's experiment had drained her strength. Hell he wasn't even sure if her stele would work and if did what would it do?

In a month she would be heading off to Knoxville for college. He couldn't be more proud. She was like Sam that way. She was a genius as far as he was concerned. She was a pretty even mix of him and Sammy. She had Sammy's brains and heart and Dean's familial loyalty and hunting instinct. Even the way she looked she was a mix. She had dad's dark hair like Sam but she had Dean's eyes. She was short like Dean too only five foot three. She reminded Dean so much of his mom it hurt. She was the mom of the Family now, always looking out for her older brothers and keeping them out of trouble as best she could. Hers was the voice of reason. And he loved her probably more than she knew.

Katie turned over in her sleep clutched at her blanket.

She was watching her brothers laughing with their dad. She knew it was a dream because dad was dead. They were inside the her house. She had made them all dinner and now they were sitting in the living room laughing like a normal family. Suddenly her family was gone and Castiel stood beside her.

"Castiel." She acknowledged in surprise. "You're in my dream."

"I needed to talk to you." Castiel said looking at her in a way that made her feel like she was in trouble.

"Okay.." She hedged.

"You made a stele today." He said to her with a nod.

She looked at him apprehensively. "Is that a bad thing?"

Castiel almost smiled, "No."

"Then what about it?" She asked him in confusion.

Now he was looking almost proud which only confused her more. "You are learning to use your power."

"What power is that exactly?" She asked angrily.

Castiel looked uncomfortable. "I am not permitted to say."

She scoffed angrily, "So what are you permitted to tell me?"

Castiel looked at her evenly, "I'm here to tell you to be careful and not to push your limits. If you had tried anything else today you would have died."

She raised her eyebrow, "That's it? You aren't going to explain the whole Shadowhunter thing?"

Castiel just looked at her emotionlessly.

"Was Bobby right? Are you my angel daddy or something?" She asked him quietly.

He looked down before answering his voice thicker than usual. "I am your father, yes."

She looked at him and said weakly, "I'm really an angel?"

Castiel's eyes were sad. "Yes."

Tears welled in her eyes, "So Sam and Dean aren't really my brothers?"

Castiel sighed. "They are your brothers, your mother was your mother and your father was your father. You were born again as a human. The day you fell from heaven your mother became pregnant and I dried my blood to a powder and mixed it with what she ate so that you would maintain some angel abilities."

She listened in stunned silence. "Why." She choked, "Why did I fall?"

Castiel looked in front of him, "You wanted to taste humanity and I could not convince you to stay."

"Is my name even Katie, because I've never heard you call me that." She asked in exasperation.

He looked into her eyes, "You're name was Kalliel." he said sadly.

"Kalliel." She tasted the name on her tongue. She expected she would have felt some kind of rightness, but it didn't feel as if it was her name.

"I must go." Castiel said. "I will be back to see you."

He didn't give her anytime to respond and she found herself suddenly awake.

Her eyes snapped open. She rolled over and saw Dean looking at her.

"How do you feel?" He asked her with concern.

She thought about it stretching her limbs, "Sore and weak." She replied with a groan.

"You should eat." he said holding out her hand knowing it wasn't a suggestion. She gave him her hand and let him pull her up.

When she got downstairs with Dean, Bobby was sitting the table with the newspaper.

"Where's Sam?" She asked quietly in a tired voice. Bobby glanced at Dean who shook his head slightly.

"What?" She asked them suspiciously.

"I was just seeing if Dean knew where he was, he left an hour or two ago." Bobby lied easily.

She hmphed and settled herself down at the table. She smiled gratefully when Dean slid a cut of steak over to her.
