The fate of Gibbs will likely be revealed in the September 20 season premiere of NCIS which airs in the show’s new time slot of Mondays at 9PM. The NCIS season premiere is called “Blood in the Water” and CBS has released a description and a list of guest stars to promote it. Here’s the synopsis:
As the NCIS team searches for Gibbs after wreckage from his boat is discovered, they find out he was tracking a serial killer with journalist Marcie Warren (Pam Dawber), who wrote an exposé on him, on the 19th season premiere of NCIS, Monday, Sept. 20 (9:00-10:00 PM, ET/PT) on the CBS Television Network and available to stream live and on demand on Paramount+.
UPDATE: CBS has now released a gallery of photos that we are now adding to this post! Sadly, these photos offer no clues as to whether or not Gibbs is alive or dead, but he is still listed on the cast list.
