Big things are happening to the gentlemen of NCIS in the final episodes of NCIS Season 11. DiNozzo is going to France, McGee is taking his relationship to a very serious level, and Gibbs is mourning the loss of someone very dear to him.

The CBS episode synopsis for NCIS 11x20 states Delilah will work together with Tony DiNozzo (Michael Weatherly) regarding a DOD cold case. Meanwhile, Tim McGee (Sean Murray) is considering asking his girlfriend to move in.

As if DOD and NCIS are not enough, the CIA is also in NCIS Season 11, Episode 20. Watch the promo video on NCIS' YouTube page here or scroll down to play the clip.

NCIS Season 11, Episodes 18 and 19 are centred on the potential NCIS spin-off set in New Orleans. Both episodes are well-received, as Scott Bakula and Mark Harmon showed positive chemistry as contemporaries on-screen. Now the main NCIS series prepares for its season finale.

Earlier, NCIS showrunner Gary Glasberg said communication is possible between Tony and Ziva David (Cote de Pablo). Tiva fans hope the NCIS Season 11 finale would feature this "communication."

"A lot of people have approached me about the idea of not shutting the door entirely on [Tiva's communication], and I'm not opposed to it," Glasberg told TVLine. However, a more recent update indicates the NCIS Season 11 finale will centre on the late Ralph Waite, who played Jackson Gibbs.

Still, there might be some surprises as Tony is sent off to France in the season's penultimate episode. Glasberg hinted to TVLine the NCIS Season 11 finale will be mostly solemn. The usual NCIS finale action happens to Tony shortly before the show's tribute to Jackson Gibbs and Ralph Waite.
