no
In Kill Ari Part 1, when she comes to the NCIS office to meet Gibbs, she meets Tony first. Then, she tells him about his schooling, childhood etc
He said, "At lo levad." That is Hebrew for, "You are not alone."
Truth or Consequences is the first episode of NCIS Season 7. The team (Gibbs, Tony & McGee) go to Africa to rescue Ziva who gets captured by a terrorist. The next episode is Reunion where the team investigates the death of 3 people who were part of a bachelor party. During this episode Ziva and Tony try to settle their differences and trust issues.
I'm pretty sure they all meet Ziva David in season three, episode one in the beginning when Tony is imagining Kate dressed as a schoolgirl.
Ziva's boyfriend, Michael Rivkin was killed by Tony. Tony and Ziva will both be back for season 7
