You're not alone. Rocky Carroll sounds a little worried, too.

Without giving too much away, Carroll's character, NCIS Director Leon Vance, ends the season as the captive of a seemingly pretty bad character, and his life is clearly in danger.

The show has been renewed for a 16th season, but no plot details have been released yet. Even the actor himself seems to know no more about his future on the show than we do.

Fans sent messages of support and concern to Carroll's Twitter account after the finale, and in response he only said, "Thanks for the kind words. Keep your fingers crossed for Vance!"

Of course, we all have good reason to worry. Fans are painfully aware that the show is willing to write off major characters -- Abby (played in all 15 seasons by Pauley Perrette) left the show last season, and people are still sore at the exit of Ziva (Cote de Pablo) in season 11. If the show is able to survive after the exit of major characters like that, you begin to realize that anyone's expendable.

Indeed, Gibbs (Mark Harmon) and Ducky (David McCallum) are the only two original characters left on the show.

We at least know that they'll be returning. When CBS announced the season 16 renewal, it mentioned Harmon by name, saying, "We're thrilled he is returning as the centerpiece of the show."

And McCallum announced on his personal Facebook page that he had signed a contract for the new season, though "once again it will be a limited schedule," to allow him time to spend with his family.
