DEAR STACY: I miss Cote de Pablo on "NCIS." Why did she leave? — Chris S., Warren, Ohio

DEAR CHRIS: The actress made it clear that she did not want to get specific about her decision to depart the show when she announced that she was leaving, calling her reasons "deeply personal." Her friend and former cast mate Pauley Perrette also described it as "personal" and "a life decision. I respect it." Certainly, it was a firm choice. The head of CBS said the network had offered her a lot of money to stay on as Ziva David to no avail.

DEAR STACY: Watching the original "Back to the Future," we started wondering what happened to the actor who played Biff? He was awesome in those movies, but I haven't seen him since. — Judy W., Cedar Rapids, Iowa

DEAR JUDY: Tom Wilson's primary career is as a standup comic. He has done many other roles, though they may not be as indelible as bully Biff — including appearing as recurring characters on "Ed," "Freaks and Geeks," "Titus" and "Fired Up," to name a few. He was in the cable flick, "The Last Ride," did voice work in the "Spongebob Squarepants" movie, and acted on stage in roles ranging from "Richard III" to his one-man show "Cowboy Tommy." See his tomwilsonusa.com website for upcoming gigs.

DEAR STACY: What, if any, relation is Jordan Bridges of "Rizzoli & Isles" to the acting Bridges family of Lloyd, Beau and Jeff? — Gary B., Sioux Falls, S.D.

DEAR GARY: Jordan is one of Beau's sons.

DEAR STACY: Can you tell me whatever happened to Howard Keel? — Cindy W., Fresno, Calif.

DEAR CINDY: Keel succumbed to colon cancer in 2004, following his long and successful career in movies, particularly 1950s musicals like "Annie Get Your Gun," and TV, including the long-running original "Dallas."
