A/N: Hi! This is my first Criminal Minds fanfiction, so I hope you like it. This idea was rolling around in my head for a week, so i finally had to put it down in writing.

This story is femslash/lesbian, so you're warned. The pairing is Emily/OC

Please enjoy!

The team looked at the assassin through the two-way mirror.

"She doesn't look like an assassin," Elle said studying the woman.

The subject sat in the interrogation room looking perfectly calm. She was in her mid-thirties, African-American with an athlete build. She had long, full black hair that went past her shoulders. Her face looked as if had been perfectly sculpted, and her dark grey eyes were striking. It was a no-brainer on how she got close to her victims. She was a knock-out. She could have passed for a model.

"Looks can be deceiving. That woman is responsible for over 200 murders in the past ten years. She's a professional hit man. I'm actually surprised that with her level intelligence that we were able to catch her," Hotch said.

"How are we going to approach this?" Derek asked. "Her IQ is higher than Reid's and she's also street smart. We can't use any textbook techniques."

"We could send in Reid, see if he can talk her into confession. With him spouting off facts, she's bound to give up within five minutes," Elle suggested. Reid scowled at her.

"I'm going in. I want to see how she handles herself during interrogation," Hotch said picking up the woman's file.

He entered the interrogation room and sat down across from the assassin.

"Aurora Jones. You are being charged with over 200 counts of murder. Is there anything you would like to say?" Hotch began.

The woman shifted in her seat to make herself more comfortable. "Just 200? You guys are seriously behind. It's more around the 451 area." She smiled at Hotch's surprised expression.

"Don't be so shocked. I'm a psychopath, remember?"

"You're not a psychopath nor a sociopath. You just kill for hire and are good at your job. And the fact that you know the exact number of people you murdered tells me that you are quite proud about your work," Hotch said calmly.

"Hell yeah, all the people I killed deserved it," she said flippantly.

"And what makes you think that you have the right to decide who lives or dies?"

"I should be asking you the same question, Aaron Hotchner. Didn't you use to be a prosecutor? Who told you that you had the right to decide who was guilty or not? How many innocent people did you throw in jail?" Aurora saw Hotch's eye twitch. She got the response that she wanted.

She continued on. "You're a prosecutor, Aaron. How many guilty people have you seen get away with rape and murder because they bribed the justice system or hired one of the best lawyers with their ill gotten gains? I was hired by people who saw that justice needed to be done. And I agreed with them."

"How did you know that they were guilty?" Hotch asked.

"They confessed right before I killed them. I did my homework. I only killed the ones that I knew were guilty. If they turned out to be innocent, their lives were spared."

"You do know that you killed a number of cops and federal agents," Hotch pointed out.

"They were all dirty. Half of them worked for gangs or mobs, and the other half just liked killing people for fun. They all had it coming to them," Aurora stated simply.

"You've deluded yourself into thinking that you're doing the right thing, there is no possible way that we can convince you otherwise."

"You can't profile me, Aaron." Hotch's eye twitched again. He didn't like her using his name informally.

"I simply believe that somebody has to take care of the people who escaped the justice system. When I found out that I could make a profit off of killing people who deserved it, I was motivated even more. You want to profile me, here's some information: I saw my stepfather rape and kill my mother in front of me when I was fourteen. He got away scot free by claiming that my jealous father did it. He said that I hated him for 'replacing" my father and that I was protecting my father by testifying against him. My father was arrested and found guilty of the crime. He took his own life on death row. Guess who got custody of me? My sadistic psychopath stepfather. That very night he tried to rape me," Aurora stated.

"And what happened?"

"He was my first kill. He thought he could take advantage of me like he did my mother. He was dead wrong. I made sure that he died slowly, and I enjoyed every minute of it. I lived on the streets for a year before somebody took me in. She became my mentor and got me into the business of killing for money. I haven't looked back on it since," Aurora ended with a smile. She leaned back in her seat.

The Director of the FBI, Robert Turpin, walked into observation room with the rest of the team.

"Did she give up anything useful yet?" he asked.

"Not yet," Elle said. "But Hotch is smart. He'll get something out of her."

Hotch took a moment to process his thoughts. There was something off about this woman. Actually, there was something off about the entire situation. A woman of her intelligence wouldn't have been caught. She was careful and meticulous. The only possible way for her to be captured was if she-

Hotch looked up at her. "Why did you allow yourself to be captured by the FBI?"

An emotion flashed across her face for a nanosecond. "I have no idea what you're talking about."

"You are way too smart to be captured as easily as you were. A moving violation? I don't think so. I think you wanted to be caught. You're on a job right now," Hotch reasoned.

For the first time since the interrogation started, Aurora looked uneasy.

Hotch wasn't giving up. "Who were you hired to kill?"

Aurora sighed. "Do you know how much I'm putting myself in danger to complete this job? I'm doing this job to help the FBI."

"What do you mean by that?"

"Do you know how many FBI employees are moles?"

"Quite a few if I remember correctly."

"Well, I was hired to take out the biggest one. The director."

Hotch looked genuinely surprised.

The team in the other room turned and looked at the director. He was turning red.

"You can't believe a word she says. She's a criminal," he sputtered.

"Well, that's for Internal Affairs to figure out," Derek said reaching for his gun.

The Director acted quickly and punched Elle in the face and ran out of the room.

By the time he reached the interrogation room, Aurora had already unlocked her handcuffs.

With surprising speed, she put herself between the Director and Hotch.

The Director was aiming two guns at the both of them. "If I take care of him, you can walk."

"Not with his team. Not in the FBI building. You're dead and you know it," Aurora said calmly.

"Step aside, forget about what you think you know about me, and I'll let you leave alive," he bargained.

She smiled sadly. "Aw, sugar. It's you who should be begging to leave alive." She pushed Hotch away from the line of fire and pounced on the director.

In a second, she had him in a chokehold. He tried to break her grip, but it proved useless. Within thirty seconds, he was unconscious. She let him drop to the ground.

"You're welcome," she said to Hotch.

A month later- FBI Interrogation room

"You have provided us with very useful information regarding the criminal activities of almost every gang, mob, mafia and other crime family in the United States. The question is why?" Derek asked Aurora.

"Because I'm getting tired. I'm getting older and killing is getting old. Why not help out the people who bring these monsters to justice? It seems pretty logical to me."

"You're unpredictable."

"Thanks, hun. Did they send you in here to butter me up? Sorry, you're not my type."

Derek chuckled. "Actually, I'm here to tell you that all the charges against you have dropped. It's quite mysterious actually."

"That's because the people who brought those charges against me were scared that I would rat them out. And I did, and now they're in jail."

"What's even more mysterious is to why you have requested to work for the BAU?" Derek said.

"I have tremendous experience in profiling people. It came with the job. And since I'm not in the system as a criminal, I can apply to join the BAU. Did I get accepted?"

"Yes, actually. With a recommendation from Hotch. That's a little odd."

"Not really. I saved his life and showed restraint in killing my mark. I think I impressed him," Aurora said.

"Well, you're on probation. Hotch is putting his neck on the line for you. He's getting a lot of heat from the people upstairs. One wrong move from you, and you're both out of jobs."

"I doubt that'll happen," Aurora said with a smile.

A year later

Aurora leaned back in her seat while she waited for the results of Emily Prentiss' background report. Right around the time they popped up on her computer screen, Derek walked over to her desk.

"Rory, what are you doing?"

"Looking up the new girl. Something doesn't seem right about how she got her job," Aurora said staring at the computer.

"The rumor is nepotism," Derek said.

"No, that's not it. Strauss hired her. I want to know why. Strauss has been after Hotch for awhile and I want to know if she's planning on using Prentiss to help get rid of Hotch."

"You have a keen eye, girl. Remember, no hacking. Leave that up to my baby girl."

"Will do, sug." Aurora typed away at her computer. She saw Prentiss approaching, so she closed the report.

"Hey, what are you guys up to?" Emily asked.

"Nothing, just finishing up some reports. Really boring stuff," Aurora commented nonchalantly.

"Well the team is heading to a bar across town. You guys up for it?" she asked.

"I'm up for anything. Rory, want to be my wing man?" Derek asked.

"Hell yeah. Watch me rope them in. Hey Derek, can I talk to Emily in private for a second?"

"Sure, I'll meet you guys in the parking lot. Place nice, Rory.," Derek warned.

"Don't I always?" she said with a mischievous grin. She stood up to be eye-to-eye with Emily.

"What do you want to talk about?" Emily asked.

"I don't know how you got this job, but if you in anyway assist Strauss in her efforts to fire Hotch, I will take you down. I know you were eligible for this job from your skills, but I know Strauss. You're someone that she thinks she can control. I want to know if I can trust you to stand up to her when the time comes."

"Are you kidding me? How dare you suggest that-"

Aurora cut Emily off. "Shut up. Keep your voice down. You're smart, Emily. I know you know what Strauss expects of you. I just want to know where your loyalty lies."

"My loyalty is with this team," Emily snapped.

"Then we should have no problems then. But know this, I'm watching you. This is my team, and I will protect them at all costs. See you downstairs," Aurora warned and walked away.

Emily sighed in defeat. She was going to have to work harder to gain Aurora's respect.

The team was at the bar with the addition of Haley, Hotch's wife. The music was playing, and the dance floor was full of young people grinding against each other.

"Damn, it's my lucky day," Derek said watching all the attractive women move their bodies to the music.

"Mine too," Aurora said taking a sip of her drink.

"Ready to go to work, wing man?" he asked her holding out his hand.

"Ready if you are," she said taking his hand, letting him lead her to the dance floor. She twirled in his arms and ended up in front of him with her back facing him.

She started moving and rolling her hips to the beat. She felt Derek moving behind her and she made sure to keep the same rhythm. Sure enough, within a minute, several pretty women joined them.

Aurora detached herself from the group and gave Derek a wink. She felt eyes on her. She turned her head slightly to see Emily staring at her. She decided to put on a show for Emily.

Aurora scanned the crowd and her eyes settled on a pretty blonde woman dancing alone. She sauntered up to the woman, put her hands on the woman's waist, and started dancing with her.

The woman responded by wrapping her arms around Aurora's neck and dancing close to her. Their bodies moved as one to the music. There was light touching, but it mostly stuck to dancing.

Aurora could still feel Emily's eyes on her, so she got bolder. She pulled her dancing partner closer to her and kissed her softly.

Emily nearly choked on her drink. She turned to Garcia who was watching Derek dance.

"Aurora's a lesbian?" she asked between coughs.

"Yep. She's a 100% woman loving woman. It's actually kind of hot if you think about it," Garcia said sipping her drink.

"Wow, that woman is full of surprises," Emily mumbled and turned her eyes back to the dance floor. She made eye contact with Aurora, blushing at the intense stare the other woman was giving her.

Aurora led her partner to the bar. When she passed Emily, she blew her a kiss.

Emily felt her temperature rising. What was this woman doing to her?
