David McCallum credited as playing...
Donald Mallard
- Dr. Donald Mallard: [about the murder victim] Did he have any previous Naval experience?
- Special Agent Jethro Gibbs: He was a reservist before he joined the police.
- Dr. Donald Mallard: I suppose it is possible that Anthony's relation to him is, uh... merely coincidental.
- Special Agent Jethro Gibbs: You wanna bet, Duck?
- Dr. Donald Mallard: Nothing I care to lose.
- Ziva David: [after interviewing a cracked-out junkie who saw the getaway car] That was a waste! He had nothing to add to his statement about the robbery at the bakery. And I'm not going back in there unless it is absolutely fumigated!
- Special Agent Jethro Gibbs: Twice.
- Dr. Donald Mallard: Jethro! Oh, thank goodness I found you.
- [walks past the interrogation room]
- Dr. Donald Mallard: Whoa! Wh-what is that smell?
- Dr. Donald Mallard: And for the grand finale...
- [Ducky rips open the plastic covering the body, Tony prepares to take a photo but stops when he sees the face]
- Dr. Donald Mallard: ... a six-centimeter cut ear to ear, severing the carotid artery. Our killer is nothing if not consistent.
- Ziva David: Is there anything wrong, Tony?
- Anthony DiNozzo: Yeah. I know him.
- Special Agent Timothy McGee: Who is he?
- Anthony DiNozzo: He's my old partner.
- Dr. Donald Mallard: Yeah, all of the prior victims were in perfect health. But this one suffered from a severe alcohol-induced cirrhosis. He must've had... quite a drinking problem.
- Anthony DiNozzo: Not when I knew him, but, uh... a few years after I left for NCIS, I know that... he was asked to retire.
- Dr. Donald Mallard: I see.
- Anthony DiNozzo: Yeah, um... Came from money, not that he ever saw much of it. His dad... wasn't around much and his mom died when he was a kid.
- Dr. Donald Mallard: So you and he had quite a lot in common. I'm surprised I never heard you mention him.
- Anthony DiNozzo: Well, you know how it is. You lose touch, time goes by. Too much time, in this case.
- Dr. Donald Mallard: And when it's gone, you can never get it back.
- Dr. Donald Mallard: [Talking to the body of Detective Price] I imagine you and Anthony were quite close. And as partners, your very lives depended on your trust in one another. Yeah, I'd hate to be in your killer's shoes when Anthony's catch up with him.
