Dr. Donald 'Ducky' Mallard
The incomparable Dr. Donald "Ducky" Mallard is the Chief Medical Examiner on NCIS.
Dr. Mallard is a Scottish-born doctor who has been long-time friends with team leader Gibbs, and underwent medical education at the University of Edinburgh.
He has a "second talent," as Gibbs calls it, to be able to read people, which he expands by studying psychology in his free time. Standard leisure activity.
In cases without actual bodies for Abby and Co. to work with, he assists by using his psychological training to decipher the clues left by the perpetrators.
Duck is an eccentric who often talks to the deceased while doing his job and rambles to his colleagues with many long, off-topic personal remembrances or historical accounts.
He's a kind man at heart, however.
He lived with his aging mother and their four corgis until she had to move out due to Alzheimer's.
Mallard drives a Morgan he restored himself. The ring tone on his phone features bagpipes playing "Scotland the Brave."
Ducky: I think I hear my pillow calling. Unless, of course, you'd like to talk about the real reason you're down here?
Bishop: A suspect got away because of me. I completely screwed up, Ducky. And I went to Gibbs to explain but he said it was fine. Which, I know it's not. And...
Ducky: Eleanor, when the world overwhelms I find the best thing to do is to start by accomplishing just one little thing.
Bishop: I really don't think I can do that anymore.
Ducky: If you actually believe that - why are you sitting on the frigid floor, in the middle of the night?
Tony: One other question, I know you're an expert in English history. And I was just wondering, have you ever heard of Archibald Drummond, the 17th Earl of Trent?
Ducky: The Earl of Trent. No, I can't say I have. Why?
Tony: I was just wondering. Thanks.
