Like, one?! *disbelieving look*

Okay, fine. *grumbles*

I think, as far as moment goes, it's the scene in Hiatus when he wakes up and demands his wife and daughter. Granted, this is more a Mark Harmon moment than a Gibbs moment, because good lord, he acts the living daylights out of this scene, but this scene breaks my heart every single time I see it.

As for favorite episode, it's a toss up between "Requiem" and "Heartland". Both tell us so much about his character, give us so much insight into the man, who he was and who he could have been.
