I think the episode is pretty good, and the acting is fine. But I do find it is a bit weird, or not Ziva like, to not get angry at her father after they find out his reason for traveling to the US is to ask a favor from Vance, and not just to spent time with Ziva, which he assured her.
All other times that she is lied to by him she gets angry, but now she only gets angry a lot later, after she finds out he lied about the date he got there and the fact that he killed someone.
