Kate followed McGee through the glass door into the lab and was surprised by the unusual silence. Okay, Abby. I'm here, what's up?

Abby looked uncertainly at McGee before showing her friend the official version of the file from Leah's and Gibbs' last case. As Kate looked it over, McGee explained his suspicions.

We thought maybe we should look into her background too, not just this case. You know, it's not like any of us know her.Gibbs knows her, McGee. Do you know what he's going to do if he finds out you've been investigating her? Kate held out the sheet. Besides, Tony and I worked with her a little bit on another case, as well. She may not be the most forthcoming person I know, but she hasn't lied to me.

Does Gibbs know she's been asked to leave six different police departments in ten years? All under suspicious circumstances? McGee countered, proffering his next piece of data.

Kate took it hesitantly and looked it over. Have you talked to her about this?

Abby hesitated a moment before responding, No, we wanted to talk to either you or Tony, first. Has she said anything to you about any of this?

Kate shook her head. She wouldn't, though. We weren't that close. What's bothering you? she asked in response to Abby's obvious discomfort.

This just doesn't feel right. Abby looked at McGee for a moment. Gibbs is gonna be pissed if he finds out. Besides, I kinda like her so far. I want to hear her side of the story.Is this all you have? Kate looked between the two.

I did manage to unearth the names of some of the FBI team members. No clue as to their current whereabouts, but here... Abby turned and pulled another page for Kate.

I'll get on this; you two, sit on that, she said as she handed the damaging information on Leah back to McGee. Give me a chance to talk to Gibbs before you say anything. Kate turned to go just as the doors to the lab slid open to admit the redhead in question.

Hey, Abby? Leah stopped at the sight of the three agents. I'm sorry, am I interrupting?No, not at all, Leah. Kate kept her denial from being over bright. Something we can help you with?I was just working on the cold cases again. Something you said yesterday, Abby, got me to thinking. Turns out both the cold case victims have no history in the files more than fifteen years back. Leah leaned against the lab table and waited.

Why would you even go back that far for history on a murder victim? McGee eyed the woman carefully.

What's the connection, Leah? Kate returned the detective's level gaze.

I don't know, Kate. Not yet. But I don't like the coincidence. Leah glanced at the lab tech and smiled briefly. I came to see if Abby could work some of her electronic black magic on a couple of names and come up with at least a thread or two. She shifted her gaze to the man who was regarding her with thinly veiled suspicion.

As for your question, Agent McGee, you go back as far as you have to in order to find a motive for murder. She studied him for a moment, then said, But that isn't what you really want to know, is it? She walked over to the man and stared him down.

McGee held her gaze and said nothing. Leah gave a faint smile and assumed a position of parade rest in front of the agent. she said in a friendly tone, if you have something on your mind, just ask. I have nothing to hide.Sure. What do you want to know? She tilted her head curiously.

You have an interesting work history. He kept his voice even.

I do, she agreed, her voice neutral. Did you have a question about it?I was curious why you moved about so much.Does that bother you? She smiled faintly.

McGee recognized the fencing match for what it was and swallowed. Taking a breath, he confronted her with what he knew. Six police departments in ten years, dismissed under suspicious circs each time. Hired at Arlington by pulling strings. You, apparently, were the reason those hostages died in that case you told us about, too. Had to leave DC because of it. I'm surprised you came back at all. McGee waited for her response.

There was complete silence in the lab. After a moment, Leah turned to Abby and handed her the files she carried. Would you see if you can find out something on these two from before fifteen years ago? Anything will do, I can take it from there. Thanks. She turned and nodded to the female agent. and continued out of the lab, ignoring McGee.

Kate glared at McGee. Thanks. Didn't I ask you not to say anything?She didn't defend herself. McGee countered.

Abby cut in before Kate could respond. Kate! Let me see that list. A beringed hand reached out impatiently for the page, forgotten, in the other woman's grasp.

What is it, Abby? Kate walked around next to the goth girl.

One of these guys was on the FBI team. The two women looked at each other.

What about the other one? Kate asked.

Abby shook her head. But that list isn't complete, either.Petty Officer Willard isn't on here, but there's a Jackson Willard, Kate noted.

McGee joined in. So somebody's killing off the FBI team? Why? And why a three-year break?Who knows. Do we know which one was the team leader? Kate looked at Abby.

No clue. Could let Leah and Gibbs in on this, they might be able to help. Abby handed Leah's files and the list to Kate.

Yeah. Or Leah could be out for revenge and using Gibbs to get it, McGee reminded the women.
