Three years is a long time, and they are professionals after all.
McGee does not spare it much thought, and to Ziva, it is meaningless. And anyway, they have a case, and they must concentrate on that. So they do. Tony and Gibbs focus all their thoughts on the work before them, and safely lock another killer away from the world. They are good, and their thoughts do not wonder.
But, that night, something comes up that means that Tony obviously has to visit Gibbs. And he makes a fuss, but he does not hesitate in driving round.
And for some reason or another, it makes sense to open a bottle of nice scotch. But they are only doing as they always would.
And as they stand in Gibbs' basement, and solemnly raise their glasses, they are merely congratulating themselves on a case well solved.
And after drinking, they are quiet because they are tired after their long day. Not for any other reason.
Not because they are silently thinking back to when they were Tony, Kate and Gibbs.
I always love reviews :)
