Double Blind is the twenty-third episode of Season Ten of NCIS and the 233rd of the series as a whole.
As a result of NCIS's response to the deaths of Eli David and Jackie Vance which was for Ziva to kill the person responsible, NCIS finds itself under investigation from a Department of Homeland Security agent and the consequences that emerge could prove damaging or even-life changing for everyone involved, especially Gibbs and his team.
The episode opens with a preview of what happened in the previous episodes and ends with NCIS Special Agent Ziva David telling NCIS Director Leon Vance that it's over, Ziva referring to the fact that she tracked down and killed her former friend, rogue Mossad operative, Ilan Bodnar in the previous episode.
