"NCIS" Season 11, Episode 23, titled "The Admiral's Daughter," airs this Tuesday, May 6, on CBS. This would have been the season finale story, but it was moved to honour the late Ralph Waite. Mark Harmon's Leroy Jethro Gibbs returns to Stillwater in Ep 24, the NCIS Season 12 finale, airing May 13. On other news, the "entire cast" is coming back for NCIS Season 12.

The NCIS Season 11 finale is expected to be a very sad episode. Ralph Waite made Jackson Gibbs so endearing for many NCIS fans.

This week on CBS, Tony DiNozzo (Michael Weatherly) flies to Paris on a mission. DiNozzo is tasked to bring home the titular admiral's daughter. Watch the NCIS Season 11, Episode 23 promo here or play the video below.

There is a chance that DiNozzo may have underestimated the trouble he would find in Paris. The NCIS 11x23 promo video shows a seemingly rebellious young woman - someone DiNozzo can easily manage. However, NCIS Director Leon Vance (Rocky Carroll) seems utterly worried.

The TV.com synopsis says DiNozzo "encounters a controversial crime scene" in Paris.

Where is Cote de Pablo's Ziva David now?

It has been almost a year since the NCIS-TiVa fans were rocked by reports that Cote de Pablo was leaving NCIS. Ziva David was last seen in NCIS Season 11, Episode 2 ("Past, Present, and Future").

Cote de Pablo stars in "The 33," a feature film which is based on a true story, a mining tragedy in Chile. It seems the actress did not film any scene for NCIS Season 11, Episodes 23 and/or 24. Tiva fans were hoping for a touch of Ziva in this season's closing.

NCIS Season 12: Everyone's Coming Back!

TVLine reported the cast members of NCIS Season 11 are all coming back for NCIS Season 12. Michael Weatherly has yet to sign, but there seems to be no reason to worry. Emily Wickersham is coming back for a full season of Ellie Bishop. Here is a photo of "DiNozzo and Bishop" on the set.
