NCIS season 2

The second season of the police procedural drama NCIS was originally broadcast between September 28, 2004, and May 24, 2005, on CBS. With the episode "Lt. Jane Doe", the show also introduced the phoofs, a black and white "preview" which was shown at the beginning of each act of that episode and has continued to be used to this day.

Norfolk Case Agent Timothy McGee, as portrayed by Sean Murray, joined the cast and was promoted to a full-time field agent, transferring to NCIS HQ in Washington to work with the Major Case Response Team, while Sasha Alexander exited the series following the finale "Twilight", where her character Caitlin Todd was shot and killed by Ari Haswari.
