A selective critical checklist of notable Tuesday TV:

NCIS (8/7c, CBS): This is the episode where we may learn what Ziva (Cote de Pablo) meant when she referred to "the one more thing I have to do before I can put all this behind me" and reunite with her family. Whatever this "thing" is, it brings the beloved agent back with Gibbs (Mark Harmon) and the NCIS team for the first time since October, and the action will continue when the show returns from its winter break on Jan. 7.

What is 'the one thing' Ziva needs to do before returning to her family?

The entire CBS lineup is new for the last time until 2020. On FBI (9/8c), the feds link a former kidnapping victim to a string of murders including the daughter of an NYPD detective. And Kristen (Ebonée Noel) needs to get her self-confidence back after a training exercise has her doubting her abilities as an agent. On NCIS: New Orleans (10/9c), the pursuit of dastardly Eddie Barnett (Eddie Cahill), who took the life of Agent Lasalle (Lucas Black) a few weeks ago, is complicated when Agent Pride (Scott Bakula) is cut off from the team.

The Voice (8/7c, NBC): For the first time in seven seasons, each team has a singer left in the competition for the finals: Ricky Duran from Team Blake, Jake Hoot from Team Kelly, Katie Kadan from Team Legend and Rose Short from Team Gwen. One will be named at the end of the two-hour live finale, and each will get to perform in special collaborations, but the coronation once again threatens to get lost amid an all-star parade of guest musical talent. The playlist includes former coach (and American Idol alumna) Jennifer Hudson performing "Memory" from the upcoming movie version of Cats, plus songs from Black Eyed Peas, Luke Combs, Lady Antebellum, Dua Lipa and Season 16 winner Maelyn Jar on (though you can just call her Maelyn now), who delivers a twist on the holiday classic "Have Yourself a Merry Little Christmas."

Well Groomed (9/8c, HBO): Think Best in Show meets Hair Battle Spectacular. If you've ever watched a professional dog show and wondered just who's responsible for those wild hairdos, this documentary introduces the curious to the world of competitive dog growing. The film follows canine stylists over a year as they dye, shave and primp their pups into potential prize-winners, with literally hair-raising results.
