In a sneak peek from tonight's NCIS, Ziva wonders about her father's intentions after his surprise arrival in D.C., a visit he claims was motivated by nothing more than the desire to see his daughter.

Ziva tells Gibbs she is suspicious and questions the purpose of her dad's visit, even if Mossad director Eli David (played by Michael Nouri) insists he is in the U.S. strictly for Shabbat dinner with Ziva.

Naturally, Gibbs volunteers to keep an eye on the situation for her.
