Double Blind

Writing

"Double Blind" was written by Christopher J. Walid and Steven D. Binder and directed by Dennis Smith. "This episode definitely does not end well - at least not for Gibbs", Waild and Smith wrote about the episode, and continued saying "DoD IG Investigator Richard Parsons is out for Gibb’s blood – though Parsons does a brilliant job distracting our team from his goal". About the ending in the episode, Waild and Smith wrote "it’s probably a safe bet that Parson will have his work cut out for him as he continues his witch-hunt. Especially if the team dynamic that played out in this episode is any indication".

Casting

TV Line announced the casting of Colin Hanks as Department of Defense investigator Richard Parsons on April 10, 2013. The casting also included the season finale episode "Damned If You Do". Executive producer Gary Glasberg described the character as "Ken Starr, J. Edgar Hoover and an angry pitbull wrapped into one". Unlike most episodes, CBS' press release on "Double Blind" did not include the other guest actors.

Reception

"Double Blind" was seen by 17.56 million live viewers following its broadcast on May 7, 2013, with a 3.1/10 share among adults aged 18 to 49. A rating point represents one percent of the total number of television sets in American households, and a share means the percentage of television sets in use tuned to the program. In total viewers, "Double Blind" easily won NCIS and CBS the night. The spin-off NCIS: Los Angeles drew second and was seen by 13.18 million viewers. Compared to the last episode "Revenge", "Double Blind" was down in viewers and even in adults 18–49.
Douglas Wolfe from TV Fanatic gave the episode 4.8/5 and stated that "[the episode] can be summed up in one word: loyalty. Or, if you like, four words: "I've got your back". Never has the family aspect of the NCIS team ever been more evident and on display, particularly in the face of a common enemy. […] The writers - through Parsons' activities - played NCIS fans like a flute in this episode."
