"Dean" Castiel's gaze examined the woman's dead body that lay across the blood splattered terrain.
"What is it Cas?"
Dean adjusted his suit after placing FBI badge on the inside coat pocket.
Sam approached the two, eyes fixed on the corpse.
"I know this woman. Well, I know who she is." Castiel did not take his eyes off of the mutilated woman.
"Who is she to you?" Dean raised an eyebrow.
"It's not who she is to me, but who she is to you and Sam." Castiel broke eye contact with the corpse to look at the two brothers.
"Well, then who is she to us?" Dean glanced at the woman.
"She is the mother of your 17-year-old half sister."
Sam and Dean looked at each other, to then turn their gaze back at Castiel with confusion.
Dean examined the surrounding area as to make sure no one was within hearing distance.
"So let me get this straight," Dean said as he narrowed his gaze towards Castiel in disbelief of the news he had just heard.
"You're telling me that my dad, John Winchester, knocked up this chick 17 years ago and this chick ended up popping out a baby girl who is Sam and I's sister?"
Dean then looked at the dead body before him, then at Sam, then back at the angel.
"You do not have the same mothers, so she is your half sister."
Dean shook his head in annoyance to the angel's response.
"Whatever. The point is,"
Dean turned to his younger sibling.
"...we have a sister…"
"Half-Sister" Castiel interrupted Dean with a steady tone.
"Shut up Cas!" Dean immediately replied, holding a hostile glare at Castiel.
Taking a deep breath, Dean turned his attention back to Sam.
"...we should tell her about, you know, her mother's death."
Sam sighed, combing his fingers through his hair and then crossing his arms.
"Dean, It's great to know we have a…"
Sam glanced at Castiel, to then turn his attention back to his older brother.
"...Half-sister, but are you sure we should bring her into all of this?"
Dean rolled his eyes.
"Sam, you're getting ahead of the situation. We don't have to tell her everything, just that her mother…"
"...is dead. Got it." Sam uncrossed his arms and turned to Castiel.
"Cas, do you know where she is?" Sam questioned.
Dean nodded, wanting to know the answer as well.
Castiel took a deep breath before responding.
"Her name is Emily, she lives in Olathe Kansas."
Sam cocked his head in confusion.
Dean stared at the angel, waiting to see if there was any more information on the girl.
"That's it?"
Cas nodded at Dean.
"That's not a lot to go on, Cas. Emily is a common name and Olathe has got to be a big city. Can't you tell us anything more?" The younger brother asked and turned to his older brother, who also seemed confused and somewhat disappointed at the lack of information the angel had provided.
"That's all I have." Castiel sighed, his gaze going back and forth between Sam and Dean.
The brothers crossed their arms.
Dean stepped forward, being careful not to tread on the corpse.
"You can't use your angel mojo to see more into it?"
"No Dean, I can't. Sorry."
Castiel returned his sights upon the deceased woman.
Sam placed a hand on his brother's shoulder and nudged him towards the Impala.
"Dean, it's all we have to go on. let's start by going to Olathe, then we will go from there."
Dean opened the driver's side door of the Impala and entered the vehicle, placing his left hand on the steering wheel and turning the key with his right.
It was then that the older brother looked into the rearview mirror to see that Castiel had vanished.
Dammit, Cas. Dean thought as the Impala roared to life.
After Sam entered the Impala, he began shuffling uncomfortably in his seat.
"Whats up with you?" Dean questioned to his brother, eyes judging Sam's movements.
"This suit is too tight."
Sam grunted, halting his attempt to get comfortable.
"Right then, Goldilocks, when we get to Olathe we can get you a new suit that's just right. How about that?"
Dean's words were very sarcastic as he rolled his eyes.
Sam froze, not appreciating his brother's tone.
"Fine, just drive."
Dean nodded his head and put the Impala into drive.
"Hey, Sam."
"Yeah?"
Dean smiled slightly.
"Do you think there's a chance our sister's hot?"
Sam glared at his brother in disbelief.
"How... wait... why... ...nevermind. Just drive."
