It had been years since she had seen the Winchester brothers. When she was growing up she was always too young to be around when they came to visit. Felicity knew she wasn't related to them, just heard ramblings about how her father had known John Winchester. Her mother always kept her away from them when they would stop by the apartment in Las Vegas after her father had left them when she was 2. She never knew why.

Felicity was away at MIT when midnight struck on her birthday and her phone rang. She had been up studying, and it was pretty normal for her to be up that late. She looked at the caller ID and it said 666. She didn't think anything of it, it was probably one of her friends playing a joke on her. They probably hacked into her phone and reprogrammed a number. She let it go to voicemail.

The caller left no voicemail.

Felicity had a clock in her room that would chime every hour. She always liked having it there to remind her if she was studying to take a break every 3rd chime.

1 am:

It was time for her to either take a break or call it a night when the chime went off on the clock. She had a final coming up and needed to study hard. She was always smart but she needed to be the best. Just as the last chime of the hour went, her phone rang again.

666

What the hell she thought. She had already checked all of her contacts and no ones name had been changed. She had even tried to type 666 to see what came up, but nothing. She let the phone ring, and it went to voicemail.

No message was left.

2 am:

She was just starting to fall asleep when her clock chimed and her phone rang.

666

Ok, now she was getting really pissed. She decided this time to press ignore and send them straight to voicemail.

Again no message was left.

She started feeling really uneasy. She didn't feel like she would be able to sleep so she turned her TV on and some movie about vampires was on. She was too tired to pay attention to it. And drifted off to sleep.

3 am:

Her phone rang. She knew who it was. She decided to pick it up this time and have a few choice words with whomever was on the other line.

"you know I am trying to sleep. So why don't you just leave me alone and call at normal times of the day like a normal human being"

The voice on the other end laughed. She heard what sounded like a British accent.

"Oh my dear, is that anyway to talk to your dad?" the British man said

"What? My dad? I know my dad didn't have an accent so why don't you just leave me alone"

"But Felicity, its your birthday. Your 18th birthday. I've been trying you all night. Why haven't you been picking up?"

"because the number comes up as 666. So ya, who ever you are, just leave me alone"

She hung up.

11am:

Felicity had to shut her phone off around 5 am when the calls kept coming. She was scared to turn it back on. Why was someone doing this to her? Why were they trying to scare her like this? She walked over to her dresser where her jewellery box was and pulled out an old card her mother had given her when she went away to college.

It was a plain card. There was only 1 sentence and a phone number on it.

FOR EMERGENCIES ONLY

555-2648

She grabbed her phone and turned it on. She wasn't sure who's number this was, or if it still even worked. Her mother had told her that the number was given to her by John Winchester, but she never had needed to use it. As her phone turned on she was relieved to see that there were no voicemails. She dialed the number and waited.

. . .

Dean always thought it was weird how every 3 months they would drive to Las Vegas and visit a woman named Donna. John never told his sons why they were going or who they were. All he knew was that she was a single mother and John felt it was his duty to see Donna and her 2 year old daughter. Most times he would take Dean and Sam with him.

Dean always went with his father. Donna, didn't particularly like having them around, but yet always let them in her apartment. But she would always hide away her daughter. Tell her not to come out of her room until they were gone. Or to go play at the park in the apartment complex until she saw the car pull away. Felicity always did what she was told.

When she had turned 16 she had been accepted into MIT on a full scholarship. He was happy for the girl. Even though he never met her he always felt he needed to protect her, or help her in anyway he could. He started visiting Donna after his father disappeared. Somehow she felt more comfortable with Dean as he got older. He was 10 years older than her daughter, and Donna had always stated that she wanted Felicity far away from his life as possible.

But now on what is her 18th birthday, he couldn't get her out of his head. He was never told why she was special to his father. He had thought maybe that Felicity was Johns kid. But they both said she wasn't. but John knew who her father was and that the man was scum, he was a piece of shit on the bottom of someone's shoe.

Dean had woken up from a long night with Sammy fighting off a ghost in an abandoned mine. The Spector was killing couples who ventured to far into the mine at night. They hadn't gotten back to their shitty hotel room till 3 that morning.

Sam was already awake doing research and Dean had just woken up. He looked at the clock.

"Sammy, its 11. Why didn't you wake me up?"

Just before Sam could answer a phone rang.

They both checked their phones, and realized it was coming from a phone that had not been used in a very long time. They looked at each other. Their fathers phone was ringing. Dean stood up and walked over to where it was and picked it up

"Who is this?"

"Um, who is this? I was given this number by my mother and given strict instructions to only call this number in case of an emergency"

"Ok. lets start over. Who is this?"

"My name is Felicity Smoak. Someone kept calling me last night and the number kept coming up six six six. It really freaked me out. And then I finally answered at 3 this morning. And some dude was saying happy birthday and that he was my dad"

Dean grabbed a piece of paper. He began writing notes about his conversation. Then he realized something.

"Felicity Smoak. As in Donna Smoak? From Las Vegas?"

"Um ya" she sounded nervous to Dean. He put it on speaker for Sam to listen.

"Hi Felicity. I don't know if you remember, but my dad John used to come and visit your mom"

"Oh my god. Are you Dean or Sam?"

"were both here actually. So is there anything else that happened with these phone calls? Are you sure it wasn't just someone playing a prank on you?" they both knew it wasn't. the number was a very specific number. They just didn't want to scare the poor girl. "So wait, you said it was your birthday. How old are you now?"

"Um, 18. Why?"

"Oh, just wondering. Never actually met you so I couldn't remember how old you were when we first started coming to see your mom" it was a lie. At the same time he was talking, he was writing on a notepad for Sam to read.

18TH BIRTHDAY. 666 CALLING HER. DAD WALKED OUT. TRAP? DEMON? HAUNTED?

"Hey Felicity, this is Sam. Where are you?"

"I'm at school. MIT in Cambridge. Why?"

"Good, today is your lucky day. That's where we are too. Can we meet and talk about this in person?"

"Sure, but how are you going to help me? Are you private investigators or something?"

"Ya, something like that. Meet at Jitters café around the corner from your school in 1 hour and we can discuss this more"

"ok. thank you. Ill be there. Bye"

"Bye Felicity" they both said together.

The brothers had nervous looking faces. Why would the devil be calling her? Was it some kind of deal her mother made? Maybe her deadbeat dad? Its been 16 years since they had started going to see her mother. So maybe it was like a 16 year deal.

. . .

FELICITY POV

An hour later Sam and Dean were pulling up to the café they told her to meet them at. She had texted them what colour jacket she was going to be wearing so they knew it was her. But when she saw the 67' black Chevy Impala she knew it was them.

She had grabbed a booth in the back and had ordered herself a latte and 2 black coffees for the brothers. She was asking for a favor so the least she could do was buy them coffee, and maybe a snack if they wanted.

The tall one was the first to walk through the door. He had brown hair that was chin length and had cheeks that looked like they were chiselled out of stone. She gave a small wave to him to let him know where she was. But her eyes darted quickly back to the door.

He was the most gorgeous man she had ever seen. He was tall, yet shorter than his brother. His hair was cropped short and was dirty blond. He looked up to see where his brother was walking towards when she saw his eyes. He glanced over to her, and she felt like her heart stopped.

The brothers walked up and Sam introduced himself first and shook her hand. She stood up and put her hand out for Dean.

"Dean, its nice to finally meet you, I'm Felicity"

. . .

DEAN POV

Sam and Dean were almost at the café when he started getting butterflies. Well that was new. He never got butterflies when meeting people for a job. He turned into the parking lot when Sam mentioned he saw a girl sitting in the back of the café wearing a pink jacket.

They parked the car, and started walking in. Sam walked in first and Dean was right behind him. As soon as he walked through the door he looked up to where Sam was walking to and he felt like he couldn't breath.

She was the most beautiful woman he had ever seen. Her hair was blonde, and pulled into a pony tail. She had dark rimmed glasses and bright pink lips. He walked up to the table and noticed she had already gotten them coffee. Oh, he was in trouble. He was supposed to be helping this girl. Not falling for her. Not to mention she was 18. He was 10 years older than her. He noticed she had spoken to him and was holding out her hand, but he didn't hear a word she said. But he stretched his hand out and took it in his.

Her hand was so small compared to his. And they were soft. He quickly let go, and told her it was nice to meet her. And sat down.

. . .

The entire meeting went smoothly and there really wasn't any more information they could get from her. They knew exactly what they were dealing with, but didn't want to share it with her. She was too precious to have her life thrown upside down. They walked back to the car and got in.

"Sammy. I need you to meet with her in the future without me. No questions. Got it?"

"Ya, sure. Whatever"

Dean pulled out the parking lot, glancing back to see the beautiful Felicity walking out and down the street.

3 Years passed. Sam had gotten extremely close to Felicity. He had helped her move to Starling City when she got a job at Queen Consolidated. He had even stayed for a month after just to make sure she was ok. They were best friends. They acted like brother and sister. Sam would always visit her when they were working on a case nearby. Or even in the next state over.

But Dean would never go see her. He had felt a strong connection to her the moment he finally met her. But he needed to keep himself distant from her. He never told Sam why. And most times he would have to hear Sam complain about it. But he never told his brother what he had felt that day in the coffee shop.

On the night of Felicity's 21st birthday Sam had surprised her to take her out to dinner. But when he got to her house there were 4 people already there. He nocked on the door and a large man answered. Before said large man could ask what he wanted, Felicity, already half drunk came running to the door.

"SHAMMY, YOU MADE IT! MY BROTHA!" and jumped into his arms

He noticed that one of the men felt uncomfortable about what she was doing, but the other 3 seemed to enjoy it.

"Hey Lis, I see you got the party started. I thought id surprise you"

"YESH, IM HAVING SO MUCH FUN! IM SO GLAD YOU CAME! WHY DIDN'T DEAN COME? I MISS HIM. HE IS SO HOT!"

Whoa, that was new he thought. He had never heard her say anything about Dean like that before. But he was pulled out of his thought by more screaming in his ear.

"COME COME, MEET MY FRIENDS. EVERYONE THIS IS SAMMY, SAMMY THIS IS OLIVER, DIGG, SARA, AND ROY! YAY BEST BIRFDAY EVA!

Just then her phone rang. She was still in Sam's arms and when she glanced at her phone he saw the look of fear. He looked down at the caller ID.
