 Doctor Donald Mallard
He looks up to Doctor Donald Mallard and cares a lot about what he thinks about him. Unlike Duckys old assisant Gerald Jackson he loves to listen to his stories and when they get interrupted wants to know what happened next. He one tried to talk to the dead bodies like Ducky, but got scared by Abigail Sciuto.
He cares alot for Ducky, shown in the episode Broken Bird.
A running gag between the two is the fact that whenever they are late to a crime scene it is Jimmys bad driving, to which he replies that Ducky has the map.
 Anthony DiNozzo
In the episode Bounce Tony is shown to confide in Palmer about problems with a case. It is implied the two hang out out of work.
Tony reguarly calls palmer 'Autopsy Gremlin' and when he is out of Autopsy in the main room makes jokes about 'how the sunlight might hurt him' and 'who let the gremlin up here'
