In Season 7's final episode Gibbs misses Ziva's citizenship ceremony due to a visit from Alison Hart. She seems to have forgiven this, however, and in the Season 8 episode "Dead Air", she asks him to play "catch" with her. In the Season 8 episode "Baltimore", after learning that her partner Tony DiNozzo arrested Gibbs when he first met their boss, Ziva comments that she would rather arrest her own father than Gibbs. In the Season 9 episode "Safe Harbor", Ziva questions his seemingly solitude lifestyle, prompting him to respond, "You're never alone when you have kids," kissing her forehead and adding, "Good night, kid."
