Some Say It's Supernatural

Chapter One: The Angel of A Demon's Daughter

"Dad?" I prayed to Crowley, AKA the King Of Hell and a single father of a half blood demon.
"Yes Princess?" He appeared before me.
"I've been invited on another hunt, it's in Harrington, Oregon. Some ghost is making it Hell for the schools down there."
"The Winchesters must have called you, am I right dear? You know they're trouble, Cassandra."
"Yes I know but I have to help these people. I can't let innocents die everyday due to some spirit or demon making trouble." He laughed, then sneezed.
"Bless you," I said nonchalantly. "Oh god! I didn't mean it!" I laughed. "Damnit!" I realized my second mistake. I just said that. Wow my normal human life really is starting to seep into my real life.
"You have your mother's kindness in you," he said. "I will let you go, but, they still cannot know I am your father."
"Ok Dad!" I said giving him a hug. He left to go talk to some of his Demons who he needed them to do something. I got packed for about a week's worth of time, it should be enough to get rid of a ghost. I decided to call Sam and Dean to let them know I was coming.
"Hey Cassy!" Dean answered.
"Hey Squirrel! I can come on the hunt! I'm ready and ill be at the house in about fifteen minutes! Say hi to Moose for me!"
"Ok Cassy!" He laughed.
"See ya in a few!"
"Ok bye."
About fifteen minutes later I showed up at the Winchester doorstep via teleportation. One of the few perks of being part Demon. Although they don't know that part. They just think I'm a young, seventeen year old new hunter, who lives down the street who's Dad is almost never home. Sam let me in and I noticed that there was someone new in the living room. Some guy with dark hair and a light colored trench coat, he started to stare at me. Things got awkward quickly as Sam and Dean looked at the man and then me back and forth.
"Hello I'm Cassandra, but you can call me Cassy!" I said to break the awkward silence. I held out my right hand to shake his hand.
"I am Castiel, and I am an Angel of The Lord." Oh Hell I thought to myself. He could easily blow my cover. "You look familiar, like someone I know..." He said with curiousness in his voice. He looked away from me then Sam and Dean went back to whatever they were doing to get ready for the hunt. I began to open my phone to tell Dad I'm ok. The brothers came out with their stuff packed and they were ready to go.
We put our stuff in the back of the Impala, underneath all the hunting gear and we began the trip to Harrington. It took forever. Dean wouldn't even let me change the music, not like he's ever let me before.
"So Sam, what is it that we are going after?"
"It's a ghost, it's been hanging out near this one school for about twenty years or so, never bothered anyone."
"So why are we going there if it's never bothered anyone?"
"Rumors have said it's turned vengeful, at least five deaths have been said to be caused by it."
"Huh, well I guess we'll find out won't we?"
Castiel kept looking at me the entire road trip down there. I hope he hasn't guessed what my secret is. If it's one thing that he would guess I'm the "Princess Of Hell" it would be him. I hope this turns out well.
