when will tony and ziva get back back together??

Tony and Ziva have never "officially" been together. They went undercover as married assasins in the episode "Under Covers" ep 3.08. In the episode "Shalom" ep 4.01, it was implied that there might have been something going on because it was mentioned to Ziva that while Gibbs had been on hiatus that Tony had been photographed going to her apartment frequently. in "Jet Lag" ep 7.13, it was implied that Tony and Ziva shared a বিছানা while in Paris, but there was nothing saying that anything actually happened. Tiva shippers (myself included) often will read into certain scenes that something is going on between them অথবা that something should be going on between them, but offically, nothing has happened that we know of.

i don't think they were together,i just think they slept together.plus,they dont really "work" together

they never were together and + there not good together and that is a fact

I dont think they were ever together but there was one episode where they were pretending to have আপনি know to solve a crime.
