If Ziva is in a relationship with this "Mr. Miami Man" do あなた think her フェイスブック would say so? And would Tony have checked?

Tony would definatly check, but I don't know if she would put it on FB

That's actually an interesting theory I've never thought about, considering she apparently has フェイスブック as mentioned during 'Bounce' in Season 6. I can imagine Tony looking it up on フェイスブック as he tends to try to found out personal details of his co-workers at times but I can't imagine Ziva being a person who shares that much on Facebook. ^_^

She have facebook? Sorry if I don't know I'm in Asia. Anyway , nothing will happen. :( If Ziva's with this guy there's a girl for tony.. "Sarah Jane Morris" If あなた like NCIS 〜ネイビー犯罪捜査班 in your フェイスブック あなた would know that they will be adding this new agent.
But I hope there's still Tiva but this girl is going to be an agent.
