I knocked before I walked in. Bobby didn't answer so I assumed he was busy. So I walked in and started to look for him. Although I had been hunting and taking jobs from him I haven't actually seen Bobby in a month or two.

He wasn't at his desk or in the kitchen so I imagined he was around back. When I finally found him he was under a car hitting something metal. I laughed a bit. "Bobby?" I asked and he pushed him self from under and smiled.

"Good! Small hands." he said waving me over. " Need you to hold something for me." He said going back under the car. I smiled and got on my knees and pulled myself under the car next to Bobby. "Hold this." He handed me one of the car's parts. I did as I was told as he tried to hit and bash another piece out. "Where are the boys?" He asked.

"Don't know." I said and he shot his head to me. "What am I supposed to know everything?" I asked with a huff.

"Oh no who did what now?" he asked rolling his eyes.

"Oh you know the usual sibling bickering." I sighed handing him his part. "Dean asked I was still around so I walked out."

"Seriously?" Bobby laughed.

"Yeah then I became an angel captive..."

"What?" Bobby asked as he pushed out and sat up. I did the same and he looked concerned. "After I left Sam and Dean yelling at each other Castiel showed up and brought me to see one of his buddies." I sighed standing up and lending Bobby a hand. "Do you know what a Nephilim is?" I asked as we walked back in side. Bobby looked at me blankly and seemed to be thinking at the same time.

"Maybe?" He shrugged. " Why?" he asked.

"Can you tell me what they are and what they do?" I asked walking past Bobby and back into the library.

"Well it depends what religion. They all have different meanings." Bobby was still confused as he followed me.

"Well how about the ones in the bible?" I asked with a sigh.

"First tell me where your sudden interest in this came from." Bobby said sitting down and crossing his arms.

"Bobby please just bare with me... I'll tell you everything once you tell me." I sighed just wanting to know everything before I upset him with everything Castiel had told me.

"Fine." he sighed. "In the bible they are referred to as abominations. The off spring of an angel and a human. There are not many around. One or two in all of history. If an angel knows about one they are supposed to kill it. They are seen as unclean." Bobby shrugged. "Two levels. Full breeds and the second generation. Angels aren't supposed to kill the second generation, but most still see them as the same thing."

"And what can they do?" I asked.

"Well the full breeds are very angel like I guess. Hard to kill and have the strength of ten angels. Then the second generation, they are hard to kill but it doesn't take as much. They are more human then anything. Although they can see an angel's true form, hear their voice, and be transported anywhere... in theory. I personally have never even seen or heard of one." Bobby shrugged.

"Well you do now." I laughed a bit and Bobby looked at me. "Castiel and his buddy Uriel trapped me in one of these..." I flipped open Bobby's sigil book. It was at the very back but the simple drawing that caught me was there. I pointed to it and Bobby just stared. " Couldn't get out. Uriel tried to run me through with a freaking spear and then Castiel stopped him. He said I was a second generation. That my mother was the child of an Nephilim."

Bobby's eyes got big and he just looked at me. "That's..."

"Crazy I know..." I sighed as I stood up and started to pacing the room.

"He tell you anything else?"

"Yeah one thing." I sighed turning my back to him. "But it's not a good thing." I sighed.

"What is it?" Bobby asked in concern.

I turned quickly and I knew my face said it all. " You can't tell anyone." I just about begged with big eyes. Bobby stood and just looked at me with a nod. "Castiel said..." I paused. " He said the boys would save the world, but I wouldn't live to see it."

"What!" Bobby almost yelled.

"Bobby please. Calm down..." I saw how red in the face he turned and how angry he looked.

"How am I supposed to calm down!" he yelled. " It was bad enough Dean making that deal and now this!" He yelled. "Jesus! Are you three trying to kill me!" He yelled as he stormed off. He headed for the door.

"Bobby... Come on." I called out following him. He slammed the door in my face and I tried to chase him but he took off in his car. "BOBBY!" I called out. Once he was gone I smacked my hand to my head and sighed. "I should never say anything." I sighed going back inside.

I spent the rest of the day alone. I went to bed worrying about Bobby, Sam and Dean. I barely got sleep. I tossed and turned. By around 3 or 4 I gave up on sleeping. So I showered and tried to forget my problems just for a minute. It was a long day after that. I spent it reading Bobby's bibles and trying to figure out what the apocalypse had in store for me and the Winchesters. And, for the first time in a few days I was lonely.
