NCIS won't be the same without Ziva David. That group has been together for eight years; the only one that could be replaced without harming the group dynamic is Vance. Evidently the contract dispute was simply that Cote de Pablo didn't sign -- because she wanted to leave the show. But I wonder why. I haven't read anything about any big offer she's received to star in her own show or make movies or recordings. Or maybe she has and just hasn't talked about it yet. Everyone is being so dang polite! Of course there are rumors about why she's leaving, but that's to be expected, I guess. Ziva is going to be an impossible act to follow; I don't envy whoever replaces her.
