“Identity Crisis" is overly circuitous in the extreme and confusing, but the ass-kicking scene in the end goes a long way to forgiving these shortcomings. The DiNozzo/Ziva relationship remains muddled while introducing Krieger to the mix, prompting some NCIS pedants to opine that Ziva is bisexual. I think this unlikely because of her faith conviction, but the thought is provocative. Should DiNozzo and Ziva ever sleep together, I suspect that will damage the balance of the show. There is no way these writers are going to allow Ziva to have an intimate relationship with Krieger either. But no matter, there remains much fun in this series.
