Tony: That's the same as saying someone you trust.
(Gibbs smiles to Tony)
Tony: Someone you depend on...your best man? (following Gibbs to elevator, Gibbs smiles again as elevator door closes) I don't think best man was the right thing to say to someone who's been married thrice.
Abby: You worried?
Tony: Oh... nah.
Abby: Yeah me too.
