Saison 2 - NCIS : Enquêtes spéciales

The second season is composed of twenty-three episodes. It marks the arrival of two recurring characters, Jimmy Palmer, who is the new assistant to Dr. Mallard (already present in three episodes of the first season) as well as Timothy McGee, a new permanent agent in Gibbs' team (already present in eight episodes of the first season). The common thread of this season is a continuation of the previous one concerning Ari. However, this character is more discreet in the plot. He reappears in the final episode to set a trap for the team and kill one of its members, Caitlin Todd, which will have a lasting impact on the NCIS agents.
