Like the rest of her colleagues, Ziva initially resents Vance for breaking up Gibbs' team. After this is resolved, she doesn't appear to hold a grudge against her boss, and they seem to enjoy each other's company. According to "NCIS" writer Christopher Waild, as a result of the murders of her father and Vance's wife in the same attack, "the tragedy of Ziva and Eli now also extends into the Vance family." Vance, aware that he cannot do so on his own for his children's sake, looks the other way while Ziva pursues revenge against the killer and continues to support her despite drawing ire from other agencies.
