What if Dean had a twin sister? What if they had been separated at the age of eight after a hunt gone bad? Read to find out. May contain gore, but if you like supernatural you already knew that.
This story begins in season two and might jump around a bit, I haven't decided yet. Cuss and possible gore warnings. R and R please but be nice. I don't own any of the characters (Except Harlyn) so, like, don't sue me or anything. And ass for the title that is based off the movie 'The Sister Act' it just seemed appropriate.
Chapter one: Sister, sister
Prologue
It started on a hunt gone bad.
I'm sure you can imagine it.
The woods. The middle of the night. The middle of nowhere. Thousands of stars, there was less pollution here, less city lights. A large hunting rifle clutched in the entirely too small hands of a terrified eight year old girl. Not that you could tell that she was a girl, with her hair cut short like her brother's, or that she was eight for that matter.
See the quick glances at her twin every few seconds, half to make sure he had her back, half to let him know she had his.
A silent promise shared only between siblings in a language all their own.
Hear the loud call of her name.
See her whip around.
The thing with claws.
The yelp. The slash. The blood. See girl fall.
Gunshots overhead.
Girl lifted out of the grass. Girl put in car's backseat.
Brother petting sister's hair.
Brother scared.
Car barrels into hospital parking lot.
Girl taken away on a stretcher with squeaky wheels.
Full day in a hospital. See Dad think. Dad takes brother back to shitty motel room.
Dad returns to hospital.
Dad makes decision.
Dad returns to shitty motel room later that night.
Dad does not have girl.
See boys confused.
See Dad tell Boys that girl is dead.
See Dad lie.

Nineteen Years later
Dean had a list of things that he would never forgive his father for.
It wasn't a very long list but it was there.
And this, this, was at the very top.
Right where 'Letting Harley Die' used to be.
Because she wasn't.
Dead that is.
He kept his hands gripped tightly on the steering wheel not even listening to the music that filled the car. Sam sat silently in the passenger seat which he was grateful for. Dad had just told them that he had lied and that their sister wasn't really dead, and neither of them could even be properly angry because he was dead. He had told Dean that Harley was alive and then he died.
Harlyn Millie Winchester.
He went over the name again and again in his mind.
Harlyn Millie Winchester.
As far as he knew Sam didn't really remember her. Sure he knew that he had a sister, Dean's twin and that she had died when they were eight and he was four, but there were things he didn't remember. He didn't know that she hated mac and cheese and how she liked Batman more than Superman or how she used to read Sam 'Where the Wild Things Are' so he could sleep at night.
How she read it so many times that she could read it without looking at the book.
These are the things that Dean remembered that he was sure Sam didn't.
They were on their way to Richmond, Virginia, the last known place of her last foster parent, Ana Sanchez. How Sam found her he wasn't entirely sure he wanted to know, but they had decided to do some research on Harley and maybe weasel her location out of Mrs. Sanchez before actually making contact.
Ana Sanchez wasn't hard to find at all. She had lived on her family farm out side of Richmond her entire life. Sam rang the door bell.
An older hispanic woman opened the door.
"Can I help you?" she asked in confusion taking in the two men in suits in front of her.
"Are you Ana Sanchez?" Sam inquired
"Yes?"
"Hi," Sam said as they both pulled out their badges "I'm agent Hetfield this is agent Tufnel" he gestured to Dean "we have a few questions about one of your foster children Harlyn... Davis?"
Her expression darkened. "Now really isn't a good time she just got back from a funeral-"
"She's here?" Dean asked
Sam shot him a look "We don't need to talk to her yet we just need to ask you some questions. May we come in?"
She hesitated before nodding and ushering them in.
"She's out back working on the car." she added leading them into the living room.
"Would you like anything to drink?" she Inquired as they sat on the couch.
"Oh, no thank you."
She nodded and sat down across from them.
"Mrs. Sanchez how long has Harlyn been living with you?"
"She was placed here when she was sixteen but she hasn't lived here since she was eighteen. I would have adopted her but we couldn't afford it." she smiled "But she still comes to visit."
Sam smiled politely back "Where did Harlyn go when she left here?"
She smiled wider "She went to a college in Boston. MIT. She got a scholarship. And then she moved in with her husband…"
"So she's married?" asked Dean
"She married Shaun Evans right out of college," she said sadly "they wanted to get married before she was deployed, but he died a few months back. It was terrible." she got up and picked some things up off the mantel.
"These are of her." she said giving each one a framed photo. Sam took in the photo of a girl with the same colored eyes as Dean in a wedding dress posing with a dark haired man in a suit, both beaming at the camera. He glanced around the living room at the other photos. There were a few other photos with her and some other kids scattered around.
Dean took in a straight faced girl in a Marines uniform. It felt like a punch in the stomach.
"Mrs. Sanchez how did Shaun die?" asked Sam
"A fire in their house. You might have met him actually, he was an agent as well." she admitted
"He must have been in-" Sam began when the back door slammed shut.
"Alright Ana, that should do it…" a girl called walking in. It was the girl from the pictures. Harley. She froze in the door way behind Mrs. Sanchez. Dean froze. It was her. She was really alive. She glanced from Sam to Dean with an odd look in her eyes.
"What's going on here?"
Mrs. Sanchez smiled and turned to look at her
"Harley these men are from the FBI they just had a few questions for me."
She walked forward to stand beside the couch.
"Can I see your badge?" She asked in a way that implied that it wasn't really a question extending her right hand.
Sam gave her his badge.
She studied it for a minute, with an expressionless face before handing it back to him and pulling a gun out of the waistband of her jeans and aiming it at his chest.
"Whoa!" Dean yelped snapping out of his shock.
"Harlyn Millie!" Shrieked Mrs. Sanchez jumping up.
"Ana go to the kitchen." she said calmly
"What are you doing?!" Ana yelled.
"They aren't feds." she said "The numbers are wrong. The badges are fake."
"No," Sam said holding up his hands in surrender "They're not, they're real."
She snarled "My husband was a Federal agent and I was in the military. I know what a real badge looks like."
Dean attempted to get up. "I have a glock leveled at your partner are you sure you want to do that?" She asked. He sat back down.
"Look," Dean said "You're right, we're not FBI,"
"I'm calling 911." Said Mrs. Sanchez moving towards the kitchen
"My name is Dean, this is Sam."
Her eyes flashed with recognition for a second before she lowered the gun slightly.
"What?" she gasped
"You know these people?" asked Mrs. Sanchez, pausing.
"Tal vez. Quédate aqui y no te muevas."* Harley said before turning back to them "Get outside. Now."
When they got outside she raised the gun back up.
"Who are you and how did you find me?" She demanded to Dean.
"I already told you. My name is Dean Winchester, this is my brother Sam. My father's name was John and My mother's name was Mary. You're my twin sister. I called you Harley. When we were eight you got hurt. Real bad. Dad told us you died."
Her eyes narrowed. She reached into her back pocket and pulled out a flask.
"Drink this." she demanded tossing it to Dean. "Him too." she said nodding at Sam. He took a swig before giving it to Sam.
Nothing. No hiss, sizzle, pain, or death.
She put the safety back on the gun and shoved it back in the waistband of her jeans.
With the threat gone her face relaxed and she smiled. For the first time Sam could really see how she and Dean could be twins. They had the same green eyes. Hell she even had the freckles. And when she smiled they both had shit eating grins.
She flew forward and hugged Dean, hard. He hesitated before hugging back just as hard. "Its really you!" She said into his shoulder before pulling back.
"And you!" She exclaimed turning to Sam. "The last time I saw you, you were in pull ups!"
Dean laughed as Sam blushed.
"God, Sammy, you got tall." She said hugging him, too.
She felt him wince a little at 'Sammy'.
"I'm sorry." she said backing up "You're what? Twenty-three now? You probably don't go by 'Sammy' anymore huh?"
"How did you guys even find me? It's been nineteen years?"
"Dad." Dean said simply.
