Paula Newsome

NCIS is expanding Director Vance's family tree, and in fact had Murder on its mind when casting Leon's missus.

Paula Newsome, who last starred on ABC's Women's Murder Club, will guest-star as Jackie Vance on the CBS drama's March 17 episode. Khamani Griffin (All of Us) and China Anne McClain (House of Payne), both age 10, appear in the same episode as Leon's kids. Leon himself, of course, is played by TVGuide.com celebrity blogger Rocky Carroll.

What brings on this exploration into Vance's thus far secretive world? According to the CBS logline for the sweeps installment, Gibbs himself will delve into the director's past when Vance "borrows" the NCIS team to investigate the death of a boxer buddy of his.

Vance's grief coupled with Gibbs' snooping ultimately leads to "a sparring match" between the two men, though it's unclear if CBS was being figurative or literal. Whatever the case, a source tells me this episode is utterly "awesome."
