Tonight's episode is a bit serious, still with a touch of NCIS humor. The drama is about Ziva's past and the humor well, the search for a playmate for Gibbs haha.
It is nice to hear stories about the character, their past, their family etc. It gives more depth to the character.
I like Gibbs' line when Ziva asked him 'are you lonely, Gibbs?' His first reply to that question was NOPE, but to Ziva, his answer was 'you're never alone when you have kids'... I think that was a nice reply.. and a sweet one. Good episode.
