Disclaimer: I own nothing except Kayla

Kayla West walked down her road in her hometown of Sioux Falls, South Dakota. Her long, blonde hair blew about in the wind, sometimes obscuring her sea blues. She looked down at her watch and started running. As soon as she saw her house she slowed down, gasping for air. She felt her phone vibrate against her leg, so she pulled it from her pocket. "Hey Dad. What's up?... No I'm about 3 houses away... see you soon." She replaced the phone and carried on walking. She pushed open the gate and walked up the path. Pulling the keys from her hoodie pocket, Kayla unlocks her front door. The moment she steps inside the door it slams behind her and she is grabbed around the waist. A knife is held to her throat and she freezes. The person holding her forces her into the living room. The first thing Kayla sees is her mother's dead body lying on the floor, covered in blood. She screams and the knife is instantly held closer to her throat. "Hush now darling, everything is going to be ok," she hears her father saying. He walks into the room and bends down beside the body. He grins up at Kayla and his eyes turn black. Kayla's eyes widen and she sucks in enough breathe to scream. Her father darts forward and covers her mouth. He tuts and shakes his head. "You're gonna come with us and you're gonna stay quiet!" he threatens her. Kayla shakes her head in fear, feeling the cold blade of the knife biting into her skin, drawing a thin line of blood. Then, suddenly, the door blows open and the lights flicker off. Kayla feels someone pull her down to the ground as screaming starts above her. She covers her head with her arms and curls up into a ball. She starts to sob, distraught over the deaths of her parents. She feels herself being pulled up into someone's arms. She clings onto them with all her strength. The person holding her sits down and starts to rub her back, trying to calm her down. "Don't worry, you are safe now," a deep voice comforts her. Eventually, she manages to calm herself down enough to look up at her saviour. His blue eyes looked deep into her own, his black hair stuck up at odd angles, as though he had just walked through a large gust of wind. "Th-thank you," Kayla stutters. The stranger just shakes his head and replies, "No apology necessary, Kayla." She stares at him, slightly confused and scared, "Who are you and how do you know my name?" she questions.

He gazes down at her, "My name is Castiel and I am an angel of the Lord. I have been sent to protect you, Kayla West."

"Why me?"

Castiel doesn't answer; he just stands up and gently lowers Kayla to th ground, keeping an arm around her when her legs give way. "It is no longer safe for you here, go and pack a bag and I will take you somewhere safer."

"Do I even get a say-so in this?" Kayla asks.

Castiel looks at her and says, "No". Kayla rolls her eyes and walks upstairs to her room. When she enters she feels tears well up in her eyes, remembering all of the good memories of her parents. She sniffs and grabs some clothes, make-up and her I-pod. As she leaves she grabs a photo album. She looks round the room one last time, making sure that she got everything important to her. She then walks out of the room, closing the door behind her. Castiel meets her at the bottom of the stairs. She lifts the bag higher onto her shoulder and takes a deep breath. She nods her head and says, "I'm ready." Castiel just places two fingers on her forehead. "Close your eyes," he whispers. Kayla does as she is told. When she opens them again, she is standing in the middle of a remote cabin. It is sparsely furnished with only two rooms. Kayla walks over the kitchen and looks in the cupboards, they are all stocked. "You will have to stay here for awhile. When you need me, just call my name. I will be back in a few days to take you somewhere permanent." With that said Castiel, prepares to leave. "Wait!" Kayla calls and runs over. "Thanks for saving me!" she places a small kiss on his cheek and smiles. Castiel looks at her and nods his head and disappears. Kayla sighs and looks around the cabin. The next few days were going to be boring.

Meanwhile, Dean Winchester was walking around Bobby Singer's salvage yard, unable to hear his brother scream anymore. He looks up when he hears a flutter of wings. "Well it's about time," he snaps at Castiel. "I've been screaming myself hoarse out here for about two and a half hours now!"

"You are not the only one that I have to protect," Castiel states coldly. "What do you want?"

"Well you could start with what the hell happened in Illinois," Dean replies.

"What do you mean?"

"Cut the crap, you were gonna tell me something," Dean says as Castiel walks over to him. "And what do you mean 'I am not the only one you are protecting?"

"Neither are of importance," Castiel tells him calmly.

Dean just stands there staring at him, "You got ass-reamed in Heaven. But it was not of importance?"

"Dean. I can't," Castiel interrupts. "I'm sorry."

He walks a little ways away. "Get to the reason you really called me. It's about Sam, right?" Dean watches him. "Can he do it? Kill Lillith? Stop the apocalypse?"

"Possibly, yes," Castiel says. "But as you know, he'd have to take certain steps."

Dean nods. "Crank up the hell-blood regimen."

"Consuming the amount of blood it would take to kill Lilith would change your brother forever. Most likely, he would become the next creature that you would feel compelled to kill. There's no reason this would have to come to pass, Dean. We believe it's you, Dean. Not your brother." Castiel walks closer. "The only question for us is whether you're willing to accept it. Stand up and accept your role. You are the one who will stop it."

Dean looks at him for a long moment, unsure. "If I do this - Sammy doesn't have to?"

"If it gives you comfort to see it that way," Castiel says. Dean looks away. "You're a dick these days." He walks away a little ways, takes a deep breath. "Fine, I'm in."

"Do you give yourself over, wholly, to the service of God and his angels?" Castiel asks.

Dean closes his eyes. "Yeah. Exactly."

"Say it," Castiel says.

Dean turns to stare at him incredulously. Castiel stares back seriously.

"I give myself over wholly to serve God, and you guys," Dean says finally, walking back over to face Castiel. "Do you swear to follow His will and His word as swiftly and obediently as you did your own father's?" Castiel asks. Dean glares at him. "Yes, I swear. Now what?" "Now you wait, and we call on you when it's time," Castiel replies. He then disappears, leaving Dean to question his decision and to wonder who Castiel was talking about.
