I really love this episode, it's a great story and the kid, Zack, is surprisingly adorable and a great actor. It's such a tragic situation – it's only the father and son, mother dead and then the kid sees his father kidnapped.
As usual, Gibbs is brilliant with kids and Tony is just terrible. Gibbs obviously had a daughter.
Poor Zack – at the ripe old age of 6, he's grown up too fast - the death of his mother, his father's kidnapping and the betrayal of an adult friend. His talk with Gibbs at the end is so tragic, no child should be that cynical.
