Undercover

Jenny Shepard isn't happy. Actually her day didn't start too bad: She had no early meeting, she had a cup of coffee and a certain Special Agent was already three hours in the interrogation room which meant that her morning started rather easy – until now.

"With all due respect, Sir, you can't be serious!" Jenny said angrily and almost desperatly. Almost.

"There are plenty other agents who are capable to handle this mission. I don't understand why you insist that I - "

"Because you are one of the best in undercoverwork", SacNav interrupted her, "and you know how to handle Agent Gibbs." he continued calmly.

"Officer David could-"

"There is nothing to discuss, Shepard." he interrupted her again. "And I can hardly imagine Officer David as Gibbs' wife."

At the word "wife" Jenny's jaw dropped.

"His what?!"

"Yes I killed him! He knew I loved Helen but he took her away from me. I thought he was my friend but he told her lies about me! He deserved it!"

Gibbs was sitting across from Patty Officer Hanson and watched him while he confessed. Finally Gibbs stood and left the room without an other word.

In the hall Tony was already waiting for him.

"Good job, Boss!" Tony grinned.

"You've got nothing to do, DiNozzo?" Gibbs asked annoyed.

"Of course, Boss, but the Director called. She wants to see you immediately. She said it's important." Tony hurried to say.

Gibbs rolled his eyes and nodded.

"Immediately, huh" he thought and decided Jenny could wait until he got a coffee refill. He just caught a criminal and deserved his caffeine before he could argue with her again.

In Jenny's office, she and SecNav waited impatiently for Gibbs to arrive.

Finally the door flew open – without knocking, of course.

" You asked for me, Director?" he asked with the usual annoyance and bitterness in his voice especially at the word "Director". Then his eyes fell on SacNav who was sitting on Jenny's couch.

"Sir." he greeted with a nod.

"Yes I did ask for you, Agent Gibbs. 20 minutes ago. What took you so long?!" Jenny asked with narrowed eyes and an icy undertone in her voice.

But before Gibbs could respond SacNav laughed and stood up.

"This is why I choose you two for this mission. You are already acting like a married couple."

For this statement he earned the Gibbs-glare from both of them. But SacNav just grinned.

"What mission?" Gibbs asked.

"Three wives of Marines have been murdered in Quantico over the past six weeks. We have no hints who the offender could be. It seems to be a serial killer so we have to hurry. You two were one of the best undercover teams and this needs to be solved very fast before the list of victims increases.

Am I understood?"

Gibbs first looked at Jenny and than back to SacNav before he answered

"Yes ,Sir, and how will we fit in there?"

"You will be working as Gunnery Sergeant, so you can check up on the husbands and possible suspects. Shepard will stay at home and spend her time with wives of marines. Maybe the killer is one of them."

"She always gets the fun parts." Gibbs repeated half ironically.

"Well, I'm not sure if it's fun being married to you." SacNav answered dryly.

Jenny let out a small laugh and Gibbs narrowed his eyes.

"What do you mean..." then he realized what SacNav's point was.

But he had no time to respond because Jenny got up and answered slightly amused

"I'm wife #4, honey."
