@xdreamsuggx Hey chin up! I don't think Ziva died!!! There was no body. Also, Tali got to the U.S. too quickly. A flight from Israel to D.C. is long, and she would've had to be checked out. I think Ziva went in hiding and Orli took Tali to the U.S. and that's when Kort blew up their house! Remember, Tali had a go bag. That would've been destroyed in the house! Also, Tali had no scratches on her!
I think Ziva sent Tony a clue through that Paris picture. THAT'S why he left. He knew Ziva was in Paris, and he didn't tell anyone to protect Ziva!
Hope I made you feel better!
