Dis: This is purely a work of fanservice. I do not own, nor claim right to NCIS, its characters and/or settings. No profit is made from this story.
They had just wrapped up a case, he had breifed the Director, taken a nice jab at the SecNav and was fixing to head back to his desk and dismiss his team.
He could usually hear his team before he could see them, today was no different.
"Man am I tuckered out." Tony proclaimed which left Gibbs expecting to find Tony lounging in his chair, with his feet up on the desk. Approaching the railing he was instead faced with the sight of Tony rubbing Ziva's shoulders; Ziva evidently enjoying the stress relief, had her arms crossed in front of her on her desk her forehead resting on them.
Gibbs' mind flashed back to the 'what ifs'. Tony with a family, then to Ziva as a Mossad assassin. How different the picture in front of him was.
Ziva said something into her desk that he couldn't hear, but it resulted in a genuinely gratified DiNozzo smile.
"Rule number twelve." part of his mind barked. He shrugged.
A vision of Tony in his basement on Christmas Eve cave to mind
"Don't make my mistakes DiNozzo. Learn from them."
He couldn't help but laugh slightly as Shannon's voice chimed in his head.
"Rule 101 Gibbs; If the rules don't work, make new ones."
AN: Just my way of not letting Gibbs let go of everthing that happened in episode 200. I may turn this into a series of short stories/ficlets. I have this whole mental image of Shannon informing Gibbs of Rule 101 shorly into their marriage, when they are trying to merge two sets of rules and figure out what will and wont work for them.
