On the tenth season finale of NCIS titled "Revenge", Gibbs will be revisited by his best friend Mike Franks (played by Muse Watson) for some moral support. Within the final hour, the NCIS team continues their hunt for Eli David's killer.
"Gibbs is going to face some very tough decisions. And who better to help him than his best friend, Mike Franks. ... Imagine having a conscience, a moral compass, that speaks to you in the form of the wonderful Muse Watson. ... This is going to be a lot of fun," showrunner Gary Glasberg told TV Guide.com.
'NCIS' season 10 wraps-up on Tuesday, April 30 on CBS.
