Zivas return was poorly executed in my opinion, and season 17 have taken a while to get going because of it.
This episode is entertaining. Yes, the storyline is a bit far fetched, but hey this is an american crime/drama show. You know what you get.
I liked Gibbs little side story, maybe we will se more of the characters "next door"? Mark Harmons performances can be a little one note (don´t know if it´s only because of the way the character is written or limited acting), so it´s good to see Gibbs express something else than looking skeptical.
