Chapter 1: New Places, Old Faces- Two Years Later

"Success means having the courage, the determination, and the will to become the person you believe you were meant to be." George Sheehan

Katlyn's phone woke her at eight. She now worked for the Missing Persons division of the FBI, they'd closed a particularly grueling case the night before and she was exhausted, so the early call wasn't welcome.

"Agent Prentiss," she said, picking up the phone, hoping she didn't sound too groggy.

"Is this Katlyn Prentiss?" a man asked.

"Yes, it is."

"Ms. Prentiss, this is Aaron Hotchner, I'm the unit chief of the FBI's Behavioral Analysis Unit..."

Katlyn still couldn't believe she's been transferred to the BAU, it was made up of some of the most elite agents the FBI had, and she'd never in a million years thought she would make the team, especially after only being an agent for two years. Here she was though, sitting across from Aaron Hotchner and her new mentor, David Rossi, who had been one of the original members of the BAU.

"I just have one more question to ask you, before we introduce you to the rest of the team. Are you related to Emily Prentiss?"

"She's my sister, why?"

"Did you know she was a member of this team?"

Katlyn shook her head, "No, sir. We haven't spoken since I was...sixteen."

Hotchner raised an eyebrow, "Is that going to be a problem? You two working together?"

"Not for me."

He nodded, "Good. Dave, take Ms. Prentiss to the conference room, I'll get everyone else."

Rossi stood with her at the head of the room as everyone else filed in. He must have sensed her nervousness, and she was thankful for the reassuring hand he placed on her shoulder in response.

"Don't worry, kid, you'll be fine," he whispered.

She nodded as a tall, gangly guy came in, followed by a brunette woman, her sister. Her sister's face registered a brief look of shock and then went stony. Once everyone else filed in, Agent Hotchner made his way to the front of the room to stand with her and Agent Rossi.

"Everyone, I'd like to introduce you to Katlyn Prentiss, she's going to be joining our team. Katlyn, this is Penelope Garcia, our tech analyst," he pointed out a brightly dressed blonde in glasses, "Derek Morgan, Spencer Reid, Jennifer Jareau, and of course, you know Emily."

She saw a couple eyebrows raise at the statement that she knew Emily.

"I'm Emily's little sister," she said, answering the unasked question.

There was another brief moment of shocked looks, before everyone made there way up to personally greet her.

"Surprise!" she grinned, when she finally made her way to Emily.

"Surprise is right," her sister replied stiffly, "You couldn't have given me some heads up? Why are you here?"

"It's good to see you too, Em. I'm great, you?" she replied sarcastically, "Agent Hotchner called and offered me the position, it was a once in a lifetime chance, so I took it. We haven't talked in years, I didn't know you were on the team until Agent Hotchner told me a few minutes ago."

"So, what did mom have to do to set this up?"

Katlyn rolled her eyes, "Mom had nothing to do with this, she doesn't even know yet. It may be a surprise to you, but I'm actually pretty good at my job."

"Right," Emily said, obviously disbelieving.

Agent Hotchner walked over, ending their conversation for the time being.

"Katlyn, Derek and Spencer are going to go help you get a desk set up."

Katlyn smiled, "Great. Thank you again for this opportunity, Agent Hotchner."

Hotchner gave a curt nod, "You have made quite a reputation for yourself, we're glad to have you."

Katlyn followed Agents Reid and Morgan to a supply closet, and helped them haul a desk out. Once they had it set down, the woman who had been introduced as Penelope Garcia came over to see if Derek could help her with something, leaving her with Spencer.

"Spencer, how long have you been with the BAU?" she asked.

"Six years," he said, sitting down at the desk next to hers.

Spencer had said he was twenty-seven when they'd spoken briefly upstairs, which confused her, "How did you get through the academy by the time you were twenty-one?"

"I graduated high school when I was twelve. I already had three PhD's when I joined."

Katlyn was silent for a moment, waiting for him to start laughing. "You're serious?" she asked, when he didn't.

Spencer nodded, "My IQ is 187."

"So you're a genius.." she said, just as he launched into a speech about genius not being able to be accurately quantified.

As he was talking, her eyes fell to a picture on his desk, it was of the team and four other people in what looked like a warehouse. What surprised her, was one of those people was Mick Rawson.

"Spencer, where was this taken?" she asked, running a finger along the frame.

He glanced over, "San Francisco. Those four..," he quickly pointed them out, "are part of a BAU red cell team there. Why do you ask?"

"I know him," she said, her finger resting on Mick's image, "He was my shooting instructor at the academy."

She hadn't seen Mick since she left the academy, she'd thought of him several times and almost looked him up, but had never gotten the nerve.

"So many questions still need an answer

Two years later you're still on my mind."

"Someday We'll Know" Mandy Moore

Katlyn couldn't believe she'd been a part of the BAU for two weeks. Her relationship with Emily hadn't gotten any better, but she'd put it aside, not wanting to let it effect her at work. As she walked across the parking lot, she found herself feeling antsy about the day, Hotch had apparently heard impressive things about her shooting ability and wanted to take her to the range and see if she lived up to the talk. She knew she shouldn't worry, she'd had a great teacher, both when she was young, and at the academy.

She'd just entered the reception area to head upstairs when a voice called out from behind her.

"Excuse me, miss,"

Katlyn froze for half a second, the voice familiar enough to stop her in her tracks. She turned, an involuntary smile crossing her lips as soon as she saw his face. He looked as surprised to see her as she was him.

"Looks like it's my lucky day," he said with a grin.

She felt herself blush, his smile...and accent, still drove her crazy. Her pulse had picked up as soon as her eyes had met his.

"I thought you were in California?" she asked, walking towards him.

"Are you stalking me, love?"

Katlyn sighed, "No, I saw a picture with you in it, and inquired about it. Spencer told me."

"Reid?" his eyes widened, "Are you with the BAU?"

Katlyn grinned and flashed her badge.

He closed the distance between them and lifted her off the ground, spinning her around, "I told you you would be a great agent."

"Mick?" Mick sat Katlyn on her feet, glancing over as Emily approached them.

"You girls just can't get over me," he said with a playful grin, glancing between the two sisters.

Katlyn laughed, giving him a playful shove, "It's impossible. We'd have to move to another continent, just to escape your ego."

"What are you doing here?" Emily asked as she reached them.

"We need your help with another case," he said, holding up the folder in his hand.

Emily nodded, "So, you two know each other?"

Mick put his hands on Katlyn's shoulders, "I taught her everything she knows about firing a gun, she's forever indebted to me."

Katlyn scoffed, "In your dreams, pretty boy. I was shooting a gun long before you."

"She's so mean to me," he false whined.

The three headed up stairs and Katlyn settled at her desk, while Mick went to talk to Hotch and JJ about the case. She looked up from a report she was finishing when Emily sat down on the corner of her desk.

"Do you intend to insinuate yourself into every corner of my life?" her sister asked bluntly.

"Excuse me?"

"First my team, now Mick, you truly amaze me."

"Here we go again," Katlyn sighed, "Are you two together or something?"

"We met working a case together three months ago, but no we're not together."

"Then what's the problem?" she asked raising an eyebrow, "Mick was my teacher at the academy, well before you even knew him."

"That embrace looked like more than something a teacher would give a student," she said, before storming off.

So obviously Emily had feelings for Mick, major ones, judging by the way she'd reacted. Great. like Emily needed another reason to hate her.

"All this time I was wasting

Hoping you would come around.

I've been giving out chances every time

And all you do is let me down."
