"Dean!" Sam growled across the room, in one sweeping motion stepping aside and and beheading the clumsy vampire closing in on him.

"Alright the plan needs work" Dean shouted back as he sliced into the vamp sneaking up behind him.

"Work? We need new friggin'plan!" Sam said backing up slowly as three more vampires began closing in pushing him towards the end of the platform and a three story plunge.

"Hey dumbass" Dean shouted pushing past the already dead bodies of the vamps in front of him and heading right to him brother. One of the vampires, the newest turned and changed directions rushing at him. Dean raised his blood covered machete above his head, the warehouse exploded in a blinding light and incredible noise sending him to the floor.

Dean opened his eyes still slightly stunned and the rotted ceiling of the warehouse swimming in front of him. It must have knocked him out cold. He was flat on his back surrounded by dead vampires and but no Sam. He bolted straight up. "Sam...Sammy" he yelled at the top of his lungs. He looked towards the platform where he had been.

He haul himself to his feet in the direction he last saw shouting. "Sammy!" He suddenly saw Sam crumbled in front of him. The decapitated bodies of the vampires in scattered around him.

Dean fell to his knees beside Sam. "Sammy wake up!" Shaking and checking him over at the same time.

"Dean" Sam groaned "Quit it. Christ my head"

Dean let out the breath he hadn't realized he was holding. "You OK, Vampire are all dead?"

"Yeah and I'm fine. What the hell was that? An angel?" Sam said sitting up.

"I think it was a stun grenade? "Dean said rubbing his eyes. "Come on let's get the Hell out of here."

"Hello Dean and Sam!" came a voice from above them

Their heads snapped up in unison, much to the amusement of the woman on the broken loft above them. She was impossible to see in the darkness of the warehouse, only a silhouette. "It was a stun grenade, Dean very good. And I just saved both your asses"

"Who or what are you?" shouted Dean as they both jumped to their feet ready to fight. "What do you want?" followed Sam.

"I am Ellie Winchester and I will meet you outside. The stench in here is getting to me." and effectively disappeared into the shadows"

"Ellie Winchester? Another relative?" Sam asked as he and Dean made their way down the ladder"

"Oh God let's hope not. I have had my fill of relatives. Alive dead or otherwise popping up to help us."

"Well she did help us Dean". Sam shrugged.

"Ha! We had them where we wanted them. We didn't need it." Sam rolled his eyes.

They arrived outside and leaning against the Impala was a woman who appeared just a few years younger then either of them. She had a slim build and about 5'7 height. Dressed in black jean, a black jacket and black suede boots that went up to her knees. Her black hair tied back into a pony tail. The top of what looked like a machete poked out above her boots and what looked like a belt holding two more grenades attached to her hip. Her arms were crossed. She stood smiling at them. Something about the way she stood arms crossed over her chest, leg kicked out in front of her was familiar.

"Let me talk Sam. I can handle her" Dean said as he stepped out of the barn and into the light of the rising sun.

"Dean" He motioned his head towards the car.

"What the... Oh she is getting on my nerves. No one sits on my baby"

"This I want to see". Sam smirked. He had a feeling Dean was in for more than he bargained for.

"First get your pretty little ass off my car! and second who the hell is Ellie Winchester? I am not in the mood for any more demons right now or any other relatives that just crawled out of Hell." Dean demanded walking faster toward the vehicle.

She said flashing her best, I am the most awesome creature in the universe smile, "That is not a nice way to talk to your daughter!"

That was not the answer that he was expecting to get. Dean stopped dead in his tracks. So, quickly that Sam almost knocked him over.

"Excuse me?" Dean said stunned.

"She said, she was your daughter" Sam whispered.

"I heard her man. I just don't believe what I heard. I don't have any kids"

At least none that he knew of. "Seriously, Sam I started young, but not that young she is just a few years younger then you I think."

"Hello, can we focus back on me? If it makes you feel better I could be Sam's daughter?" Ellie smiled

Now it is was Sam's turn to be stunned. "Alright she is crazy! Maybe she is one of the supernatural book fans"

"or a nut job" Dean suggested.

"Gentlemen" she said stepping forward uncrossing her arms to reveal a grenade in one hand and a pin in the other. "What does a girl have to do around here to hold your attention!"

She had their attention.

"Alright sweetheart" Dean said quietly slowly backing up. He could hear the crunching of gravel behind him as Sam did the same "Put the pin back slowly and everything will be ok."

"Stop! Both of you! NOW! Let me cut to the chase. I am, from the future and Dean is my father but you had a big hand in raising me Uncle Sam. I came back because I needed a safe place and who better then with you too."

"Bull" Dean spat

"What you think you have the exclusive on time travel? Let's say that I have some friends in high places and Uncle Bobby's library. Two great things that go great together"

"So you want us to believe that you popped in from the future? Why here and now? I am so not buying this."

"Dean we time traveled its possible." Dean shot 'whose side are you on look' and Sam immediately quieted down.

"Look I know you have tons of questions and I want answer what I can. But first things first. Call Castiel. He can verify that I am a Winchester."

"What is he a walking DNA test?" Dean scoffed. "How the Hell does she know about Cas?" Dean whispered to Sam who was standing beside him.

"Stalker?" Sam suggested

"Never mind" Ellie sighed. "Castiel! Castiel!"

In less than the space between heart beats Castiel stood between the brothers and the woman dressed in black.

"Who has summoned me?" Castiel spun around in the direction of Ellie. Spotting the brothers he stopped "Sam, Dean are you alright? Why have you brought me here?"

"We didn't this nut job did!" Shouted dean.

"She is carrying a grenade and says Dean is her father. And since she is holding that grenade we are sort of compelled to listen."

"Castiel". Ellie said softly, almost sweetly. Castiel turned on his heel and looked at the woman in front him. He was concentrating on her, hard. As if the entire world had fallen away, as if there were no one else anywhere but the two of them.

"Why have you called me" his voice commanding and intimidating. Ellie appeared shaken for a fraction of a second before the emotion melted away into resolve. "I am Dean's daughter. "Tell them Castiel. I know you can tell. You heard me that alone should indicate I am Winchester. "

Castle stepped closer to her. Very close. Dean would say he was invading her personal space. He looked her up and down circling around her slowly. Until he had walked in a complete circle.

"You know that weapon does not intimidate me. I am an Angel of the Lord"

"I know" she said softly. He stopped directly in front of her and made direct eye contact.

Without ever averting his eyes, blinking or even turning to look at them. "Sam, Dean she is a Winchester and is not from this time.". She returned his gaze with equal intensity.

Suddenly he broke it off. "Will there be anything else, gentleman?"

"Wait minute. She is telling the truth?" Dean stared at her

"Yes" Castiel said matter of factly

"How can you tell?" Sam was obviously curious

"The smell..." Just as matter of factly

"The smell? Sam repeated.

"Yes, human being all have a smell. Families tend to resemble each other."

"So is she my daughter?"

"I cannot tell, but she is the off spring of one of you."

"I must go. Raphael has a plan to take over a large section of heaven, I must return."

"Wait. That's it. You're leaving us. Aren't you even curious why she is here?" Dean started to walk towards Castiel

"Have you asked her?" Castiel turned to look directly at Ellie

"For my health?" Ellie smirked, joining in the conversation.

Castiel looked at her again very hard, almost as if he was trying to see how she worked. Ellie immediately stopped smiling. "What you call sarcasm. I see the resemblance between you and Dean."

Turning towards Dean "I am very curious. Keep her safe. I will be back"

And he was gone...

Everyone stood for a moment looking at the empty space Castiel had been standing. The sun had now completely risen over the horizon and it was morning.

"Ellie" Sam started "What do you say you put the pin back in the grenade and have some breakfast?"

She smiled at him genuinely this time. "Oh and yeah let me." She put the pin back in the grenade slowly and finally released it. It was obvious this was not her first time replacing a pin.

Everyone including her sighed.

Grabbing Sam's arm, "No, this is not awkward at all. We still don't know why she is here or if I believe her."

Ellie walked towards them and away from the car. Her hands open and at her side. "Look Dean I understand why you're being cautious. You don't know me and while I have a lifetime of memories of you and Uncle Sam, you are not yet the man who is my father. But you sure look a lot like him and the voice is still the same." She was standing close to him. Identical set of green eyes stared into each other. "Everything in me wants to through my arms around you" Her eyes filled with unshed tears.

"So with that all said I will do whatever you want to gain your trust." She leaned down and pulled a silver knife from her boot and ran it across her palm.

"Hey, Hey wait" Dean grabbed her wrist. "Stop it Ellie. I get it. You aren't a monster." She raised her eyes from the cut to meet his. "This is just a lot to take in ok."

The paused for a second just looking at each other. Ellie smiled at Dean who was still holding her hand. Without a moments hesitation she threw herself at Dean, who caught her. She wrapped her arms around his waist and he slowly wrapped his arms around her and patted her back.

Sam smiled and awkwardly stared at the ground. It was obvious he felt like he was intruding on this private moment.

"We should get that cleaned up Ellie. Come on back to the Impala" Dean said softly.

She pulled away from his arms and smiled at him. Letting go of him as then threw her arms around Sam in an effort to include him. "I missed you too Uncle Sam!"

Sam slid his arm around her and squeezed her back.

Dean led Ellie to the Impala. "Why don't you give me the grenades and we'll put them in trunk."

Ellie handed him the belt of grenades.

"Hey these are pretty good quality! Military grade. Good taste. I have just like these"

"Since when do we carry grenades? Dean"

"Since I dont know... forever." Dean shrugged

"Well you're carring one less now. Those are the ones from the car." Ellie confessed looking guilty.

"You broke into my car? I am not sure if I should be shocked or proud?" Dean looked up from the trunk.

"No I did not break into the car. I have keys" Ellie smiled. Jingling them in front of her.

Sam burst out laughing as he looked between them shoving his gear in the trunk. "I think I am going to love this."

"Had keys! "Dean snatched them from Ellie's hands. "Ok first rule no one touches my baby!"

"I thought I was his baby" Ellie smiled

"She has a point Dean."

"Sam don't make me beat you or spank here! " Shouting across the car. "Get in and let's get breakfast and tell us why you're hiding here."
