According to Deadline, Polo will play Vivian Kolchak, Parker’s ex-wife, and a former FBI agent who left the FBI following their divorce and took a Defense Department job as a paranormal investigator. She is set to first appear in the season 19 finale and then return sporadically in season 20. At PaleyFest—A Salute to the NCIS Universe event, NCIS showrunner Steven D. Binder exclusively teased to Parade.com what is to come in season 20 saying, “We’ll be seeing their non-work life a little more. I think one of the cores of the show is the cases. The show’s called NCIS, it’s about the Naval Criminal Investigative Service. But anyone who watches the show knows that it’s really about the people on the show.” Viewers had been given extensive knowledge of Special Agent Leroy Jethro Gibbs’ (Mark Harmon) background, so it is no surprise that we will start to see the onion peel on Parker’s life before NCIS. “I always tell the new writers your cases have to work, they need to be funny, they need to be interesting, they need to be in a new arena, they need to be clear, they need a twist and they need to be exciting to the end,” Binder continued. “And nobody cares about any of it. What they care about is the people on the show and their history. So, you’ve got to get that straight so we can then dance in the realm that people care about.” NCIS airs Monday nights at 9 p.m. ET/PT on CBS. Next, Where’s Gibbs?
