I wa running for something like an hour and I couldn't fell my feet anymore, but I didn't care. I couldn't stop.

I CAN'T lose him.

Especially not because of him: Crowley, for everyone "The king of Hell", for me…

… my father.

At first I didn't understand why he took him, I mean he doesn't even know about my existence, so why take him. We were nothing but humans to him.

Then the thought came across my mind… he knows.

He knows that I'm his daughter, that's why he took him, he wanted to use him to get to me, to my powers.

This was all my fault.

For all of my life I tried to hide myself, my powers, but I failed and now the man I love is in danger and I don't know where is he or how to save him.

I was a mess.

I should have imagined that it would end up like this… I should have know this since the day I was told who I really was…

Flashback- 10 years earlier

It's finally my birthday! Finally 15…

Knock knock

" Come in m…" I hadn't even finished the sentence that she came in, screaming

" Happy birthday honey! "

The she came and just hugged me.

" Mom please, I can't breathe…"

" Oh, sorry… But you have to understand: my beautiful girl is getting 15! How can I be calm?"

Then she started caress my face and I couldn't help myself from staring her.

She's so gorgeous. Whit her long beautiful blond hair and her blue eyes… she looks like an angel.

I'm pretty much like her: blond hair, rose lips, little nose, but my eyes are brown.

"… Lucy? Earth to Lucy? "

" What?" crap I just got caught stating at her.

" I was asking what do you want to do today"

" Ah… I don't know, I heard about the opening of a new zoo near here, maybe we can go" even though I hate see animals inside cages I wanted to see the dolphin.

What a weirdo…

" Okay, if that's what you want, we'll go after breakfast" she gave me a kiss and walk downstairs.

We were walking around the zoo from a couple of hours and in a few minutes the dolphin show would start.

" Come on mom, we'll miss the beginning.""

Here we are, in the front row, the show had began from 10 minutes and I could honestly say… it was so damn boring!

Then I felt it, a strange feeling, like if someone was watching me… I turned around but there was no one.

Well maybe I was getting crazy… so I decided to focus again on the show.

Once at home it was already dark and I still was feeling observed.

When I walked downstairs I saw my mom so when she asked me what was wrong I decided to tell her

" Mom I keep feeling like if someone is watching me" then I saw it, fear. Her eyes were wide open and her face pale.

" Mom what's going on?"

" This is not possible, they can't have found you" I started to panic

" Who? Who found me? Tell me what's going on, TALK!

Suddenly, without say a world, she ran into my room and stars to pack up.

" Mom, why are you packing, what's going on? YOU'RE SCARING ME!" I yelled the second part and finally she looked at me.

" Lucy, baby. There is something you need to know…"

" About what?" I wanted an answer but I was also scared. Why was she so scared?

" About you, and who you really are "

I started to shake, tears were coming down my face. Who I really am? What does that supposed to mean? I'm Lucy!

She took my hand and looking into my eyes she says " You're not human "

" What? Are you insane? If I'm not human than what the hell am I?"

" I though I could protect you, but even since when you were a child I could see part of him in you "… " I though that thanks to my being an angel you wouldn't be like him, but I was wrong, so I put limiters on you? "

" Limiters? Limiters for what? And what does it mean that you are an angel? " I thought my face was now just as pale as hers. I was so confused, what was she talking about?

" For your powers, they manifested when you were 5. That day you almost made me have an heart attack " she chuckles.

" Powers? Have you lost your mind? And why did you say that you were and angel?" I was yelling now…

" I says that I'm an angel because that is what I am and… " " NOOO" I stop her, " Angels are not real!" then I saw them.

2 black wings, coming out from her shoulders, but they didn't seem real, they looked like shadows.

My heart was beating so fast, I could't breathe…

" How… How is that possible? Am I like you?" my mother face softened and smiling at me she said " Yes and no. You are only half angel… 16 years ago I met a man, he was handsome and fell in love… few months later I found out that he was non who I thought he was and that he was just using me to get my Grace, so I ran away"

" What's a Grace mom?

" A Grace is the most important thing for an angel, It's the place where our strength lies along with our powers."

" How did he knows abut you that man? He was like you?"

She laughed at me " No, honey, she was not like me, he was a demon"

" A DEMON? "… " Then what happened?"

" I found out I was pregnant and my people, the other angels were not so happy about it so they told me that I had to get rid of you, but I couldn't." she took my face into her hands and smiled " I couldn't lose the best thing that has ever happened to my"

Tears were coming down my face…

" Mom who was looking at me earlier? " I suddenly ask.

" Angels, they found us and they probably want to take you away."

" Why?"

" Because you are special "… " Because you are OUR daughter "

" Our? " then I realized " The demon… his…" I couldn't finish the sentence, my voice was stuck in my throat.

" Yes Lucy, the demon is you father…"

Then everything turned black….

That day still appear in my mind.

My mom died 2 years later, traveling nonstop had weakened too much.

The day she died, was the day when all my limiters stopped working and I saw why they were there, what I was really capable of and I realized…

I realized why they wanted me….

…My powers, there is nothing I can't do with them.

I guess this was why he wanted me … He figured it out what I was capable of and wanted to use my abilities to became non just the King of Hell, but the King of everything.

There was only one problem: I couldn't control them. My powers were too strong, even for me…

Who was I?

I was Lucy Black, and I was half angel and half demon

My evil father, who just founded out my existence, had kidnapped my boyfriend and I had absolutely no idea of how to save him…

Balls!

Sam POV

We just arrived in an abandoned factory after 8 hours of travel. I didn't know what was going on here but Castiel said it's important, that he could fell a lot of power coming from this place.

I honestly didn't fell anything special, but maybe it was because I was not an angel like him.

" Hei Cas, do you know why we are here or you just wanted to spend more time with us? " Dean finally said while grinning.

" That's right Castiel, why are we here? " I needed to know.

Castile kept walking without answering us, but after five minutes he turned around " Guys, I heard that Crowley is here, and he's keeping an hostage. "

" So? What's new? What's special about this hostage that has make you drag us here? Have you forgot that I'm trying to find out how to delete this damn mark from my arm?"

I knew Dean was still worried about the mark of Cain, and I was worried to.

This must be important but Castiel was not telling us anything! God, what the hell was going on here?

Suddenly we heard an explosion, we were all shocked, since when demons use weapon that can produce explosion?

We started running and when we arrived in the place of the accident I remained paralyze.

10 demons were dead, covered in their own blood and there was a girl in the center, if could call her a girl…

… she had 2 big wings covering almost her body, but her wings were not like those of the others angels: they were real, white and beautiful… I couldn't stop staring at them.

" Girl what happened here? " Dean voice woke me up from my astonishment.

But still I couldn't stop staring at her, I mean she was something beautiful and scary at the same time!

Then she looked at us and her face was something I would never forget…

C astiel POV

What had happened to all of these demons? I had never seen anything like that and looking at the boys face I assumed that neither had they.

But what shocked us the most were her wings, those astonishing white wings.

She was not an angel but yet I felt like we were connected somehow.

" Girl what happened here? " Dean suddenly said.

She looked at us and what I saw in her eyes was something that, for the first time in my life, left me speechless…

Dean POV

Something was wrong… my mark was glowing, like if this girl and what happened here was somehow connected to it.

I briefly looked around and the way this demons got killed was amazing… I knew was something that only I could say but I found the way they died amazing.

If this girl was the one who did it, I was going to ask her bloody autograph!

Then I looked at her, I thought she was blond, but I wasn't sure, her wings were covering her completely.

Wait? Did I have just said wing?

Wow, those were real wings, not like Castiel's, but real, like the ones in the movies. I wanted to touch them… Wait what? What was I saying? I guess turning into a demon and then into a human again changed me, but somehow I felt drawn to her, and that's something I had never felt before.

What the hell was going on?

I needed answer so without thinking I said " Girl what happened here? "

Few seconds later she raised her head and looked at me and I felt my eyes widen in shock… what was she?

Nobody POV

She looked at them and what they saw paralyzed them...

Her eyes were completely black and from them were falling red tears… she was crying blood!

" What are you? " she heard the boy with long hair ask her, but she couldn't answer, her throat was locked.

Tired of not having an answer Dean and Sam raised their gun ready to fire, but Lucy didn't care. After what he did to her, to HIM she didn't care.

Suddenly her wings started glowing and after few second they disappeared leaving the girl uncover.

Finally the boys could see her: she was blond, young, probably around 25, and even with her face covered by her own blood, they could state that she was very pretty.

Then they saw it. The body of a men, his eyes were closed and from the look on the girl face they assumed that he was dead.

" I'm going to ask that again: what happened here? " Dean said again with his gun pointed at her head.

Hearing the noise of the trigger Lucy shocked her head, and Castiel was the first one to notice that her eyes were no longer black, but were brown and still covered in blood.

In an instant Castiel moved toward the girls caught her before she hit her head on the floor. Quickly Sam and Dean ran towards them and they saw the girl looking at them before says " Who are you? " then she passed out, overwhelmed by grief and exhaustion.

Castiel got up picking her bridal-style ready to leave, when he heard

" Cas what are you doing? Where are you taking her "

Turning his head he looked at Dean and said " I'm taking her to the car, she needs to rest "

Now was Sam turn " We can't take to the our car, what if she tries to kill us. You saw her eyes: they were black like demons ones. "

" Yeah Cas, Sam is right. We can't trust this girl. What if she is the one who did that? " and he pointed at the demons' corps around them.

" I don't care "

Sam and Dean looked at Castiel disbelief, he had never acted like this. The angel continued " I'm going to take care of this girl, you saw her wings. She is something new, something that I've never seen before.

I feel that I have to protect her. " surprised by his own world he stared at the sleeping girl and he felt his heart tighten at the sight.

Dean looked at his friend and finally realized the burning sensation coming from his arm.

Sam observed his brother worried " Dean are you alright? Is the mark causing problems? "

Dean looked at him " No Sammy, don't worry, it's nothing "

" Don't lie Dean. "

Not wanted to lie to his brother he took a deep breathe " Fine Sam, it's like the mark is telling me something.

" Like what? "

" I think the girl is somehow connected to it. "

" Connected in what way? "

" I don't know Sam! " Dean yelled " I feel drawn to her "

Dean watched at the resting girl surprised by what he had just said.

Sam was surprised too.

What was in that girl that made his brother and friend act so weird?

" Sammy " Dean said slowly " I think we need to take the girl with us. Just to found out what's going on. "

Still shocked, Sam stared at his brother who was now looking at the girl just like Castiel.

" Fine Dean, we'll take the girl with us, but if she does anything dangerous we kill her."

" I'll stay with her, I mean you… " Castiel said " I think this girl is special and I want to know why she has wigs. "

After that the boys reached the car they put the girl on the back seats, she was still resting in the arms of the angel who decided to stay in the car for all the travel.

Surprised by their friend decision, they got in the car and after looking at each other, they mentally asked if this day could became even more weird.
