An NCIS, Criminal Minds crossover that I did because of an RP storyline I'm doing with a friend. Most of it is fiction, created by me and her of course. Neither character is mine they are property of CBS. So this one is for you Talyn64

Caitlin Todd had kept her life pretty much a secret to her fellow NCIS agents. Not a one of them knew her past, where she came from or what she gave up in order to move to DC and join the Secret Service and then later join NCIS but it was a choice she had made long ago to keep her life to herself.

Her family wasn't something she talked about much, her older sister Rachel being the only one in her immediate family that she still talked to. She didn't see much of her parents. As a child she had spent most of her life with her best friend in the world, Emily Prentiss. Emily was the one person that had never turned her back on Kate and it was something that Kate had always kept close to her heart. She missed Emily, they lived together most of their lives and it wasn't until after college when she got the offer for the secret service that she and Emily had no choice but to go their separate ways.

Right now, she wanted to talk to Emily desperately. Her boss, Jethro had just proposed to her. She and he had been fooling around but Kate had never seen this coming. Part of her wanted to say yes but she just wasn't sure what this would mean for her career. They had kept their relationship a secret but now if they were going to get married it would obviously become known to the rest of the team.

They weren't busy at work today, no cases so she got permission from the Director and she drove down to Quantico. When she walked into the BAU she looked around for Emily, she just wanted her best friend. "Kate? Is that you?" she heard a familiar voice and spun around to see Special Agent Derek Morgan.

"It's me Morgan! It's been a long time."

"Yes, it has been a very long time. How are you?" he asked as he took her in his strong arms.

"I'm doing very well but it's one of those moments where I need my best friend. Any idea where I could find Prentiss?"

"Hmm… try turning around Agent Todd," hearing that voice brought a huge smile to her face as she spun around and saw Emily. "It's been forever girl how have you been?"

"I'm not bad. Can we talk babe?" Kate asked, trying to hide the confusion in her voice.

Emily was smarter than that, she was an FBI profiler and she could tell when her best friend was upset. "Yeah sure, come on kiddo let's go in the team room." Emily knew something was wrong but she couldn't hide her excitement that her best friend was once again there with her. "What's going on Kate?" she asked as she shut the door, giving them privacy.

"Well…" Kate sighed deeply. "We haven't talked in a few weeks because of work schedules so let me catch you up. I've been sleeping with my boss."

Emily's mouth dropped at this revelation. "You've been what?"

"Sleeping with Gibbs… it just sort of happened but that's not really the problem at hand."

Nodding, she sighed. "Okay… then what is the problem Kate? You're not pregnant are you?"

"God No! At least I don't think I am. But Jethro proposed. He wants to get married and I am just not sure what to do. We've kept everything a secret up until now and I don't know what to do because I don't think the director will be happy to find out about this."

Emily tried to hide the sudden twinge of sadness she felt in her stomach to hear that Kate was possibly getting married. She couldn't tell her, not like this, not here. All she ever wanted was her best friend to be okay and to be happy. "Kate, you have to follow your heart sweetie. If you love Agent Gibbs and you can see yourself spending your life with him than you should go for it. That's something that only you can decide honey."

Kate took a deep breath, she knew Emily was right. She was the only one that could decide whether or not marrying Gibbs was worth the risk of everything. "Thanks Em… you always help me figure things out."

"That's what best friends are for Kate. You know I will always be here," Emily replied. Kate nodded, looking across the table at her best friend. She wasn't sure why she felt a sudden sense of guilt when she looked at Emily. She felt like she was hurting Emily, she saw pain in her eyes and she didn't understand why.

"I know Emily and I will always be here for you too. Just like it's always been. We just have to work on seeing each other more. I miss you Em."

Emily nodded, unable to look Kate in the eye in that moment because she missed her too, more than she could even express to Kate. " I miss you too sweetie, I miss you too!"
