Chapter 1

= New York City, 10.00 GMT-5 =

"Lieutenant-colonel Sørensen."

"Yes sir."

A second later, the phone was hung up and the lieutenant-colonel up on her feet. Before reaching for the doorknob, she came to a stop in front of the door, straightening her uniform and fixing her hair in a bun. Once satisfied with her appearance, she walked purposelly towards the lift. She knew why her boss called her, but it doesn't make these few minutes of waiting any easier. She might know why she has been summoned, but has no clue as of the direction this meeting will take.

The knuckles of her left hand rasping at the door, she thought: "God, I hate diplomats!"

"Sir, you wanted to see me?"

"Yes, please take a seat."

Unable to figure out if it was a good or a bad thing, the lieutenant-colonel reluctantly sat down. Accross the desk, a man in his late 50's wearing an expensive and impeccably cut dark suit looks at her before giving her a small smile.

"The operation has been green-lit. "

Releasing a breath she didn't know she was holding, she asked:

"When can I go?"

"A diplomatic car is already waiting for you. Grab the files you need and a go-bag, you probably will have to spend the night there. Oh, and take major Watson with you"!

Walking out of the office after saluting her boss, she couldn't help but smile. She knew she shouldn't be so happy, especially judging the circumstances, but she'll take every chances to be back in the field she gets. Having the major as a sidekick is the icing on the cake. Reaching for the phone in her pocket, she hit speed-dial. After a few rings, she heard a slightly breathless woman pick up:

"Major Watson."

"You know Casey, caller ID exists for a reason," she teased.

"Yeah well, it kills all the fun, lieutenant-colonel."

Sørensen could hear the smirk in the major's voice. "Casey, stop being a smartass and hop in the shower, the joint operation is a go. As soon as you're ready, we hit the road."

Suddenly very serious, major Watson answered with a short "Yes ma'am" before hanging up.

30 minutes later, the 2 women were in the car on their way to Quantico.

"So, who are we meeting again?" asked major Casey Watson, her eyes trained on the road.

"SSA Aaron Hotchner, BAU chief. I spoke to him on the phone while you were cleaning up after your work-out. He will gather his team as soon as we arrive. And before you ask, no, he doesn't know why we come to see the BAU. Saying he was shocked to hear who I was would be the understatement of the decade."

"I can't blame the boss for wanting to keep this story under tight wraps, it could be a possible diplomatic incident."

"Incident doesn't even start to cover it, Casey, it could be an international clusterfuck yes!" said Sørensen while pinching the bridge of her nose.

Her eyes leaving the road for a second, the major stole a glance at the woman sitting in the passenger's seat. "She looks tired, and more worried than I've ever seen her, and that says a lot. I wouldn't like to be in the shoes of our guy the moment she puts her hands on him," she thought.

"You need to rest, we have a long day ahead of us. And for the love of all that's holy, take a painkiller! We need you to be at the top of your game, not distracted because you're in too much pain to focus!"

Shocked by her subordinate's last sentence, Sørensen looked at her a question in her eyes.

"You seriously think I didn't see you were limping? True, it's barely there and I am sure no one else noticed. But I know you."

These last words were said softly, the tone of her voice full off care and concern. All lieutenant-colonel Sørensen could do was smile and reach for the bottle of pills in her bag. Following the major's advice, she let her head fall back on the seat and close her eyes.

4 hours later, she felt a hand on her left shoulder, effectively waking her up.

"Already there?"

"Yes, you slept for a while. You needed it", she added, knowing Sørensen would feel guilty for dozing off during the most part of the trip.

"Looks like I did... alright then, let's go." Shaking her head one last time to make sure she was fully awake, Sørensen grabbed her go-bag and the box of files from the trunk, while Watson stretched after the long drive.

Bags in hands, both women looked at eachother, making sure the uniforms of lieutenant-colonel of the norwegian army and major of the US marine corps were impeccable. One last look at the light blue berets on their heads, and the 2 soldiers walked accross the bullpen.

They barely had the time to take a few steps inside when a man rushed towards them.

"SSA Aaron Hotchner. Welcome to the BAU."

Before the women can introduce themselves, they heared a voice ringing in the open space "Kaja?"
