History Characters / ScrubsMainCharacters

* HorribleJudgeOfCharacter: As evidenced by who he allows into his "Brain Trust", The Janitor isn't very good at who he chooses to listen to:

** The Todd is very obviously a poor given that he is at best a GeniusDitz. Even The Janitor admits Todd annoys him.
** While Doug is better than the two people who replaced him, he is also only a GeniusDitz at best as he is the second worst doctor in the entire show (with only Cabbage being worse) and is very weird in general.
** Lloyd the Delivery Guy is a burnout drug addict who is barely keeping it together. Even after Lloyd admits to having tried to fake his death due to being thousands of dollars in det, The Janitor only give Doug the spot back until Lloyd is back on his feet.

* BerserkButton: While most of his anger is just bluster, doctors who don't even try to improve or don't take the work seriously are one of the few things to make him genuinely furious.

* LastNameBasis: Usually referred to by his last name.

* TookALevelInKindness: He'll never admit it but his time with J.D. does make him a better man, more open to accepting help and better at expressing his emotions in a healthy way, exercising patience and forming bonds with people, allowing him to become a better father to Jack and later his daughter. He even takes his role as a mentor more seriously, becomes a better leader to the hospital and his students after seeing how a willingness to step back and see if his methods are working with J.D. improved things and develops greater patience, even showing Ed immense tolerance and giving him a legitimate chance to show his commitment to being a doctor. It admittedly doesn't work but that was only due to Ed's staggering laziness and immaturity, not Dr Cox's behavior.
* ToughLove: This is part of his SinkOrSwimMentor shtick.

** However, in the time between "My New Suit" and "My Inconvenient Truth", their role switched, as J.D. when through extreme {{Flanderization}} in season 6 into a {{Manchild}} who spends too much time goofing off and is unable to take of himself, while Dan got his life together, got a new job he's really good at, and has saved enough money that he can afford to buy J.D. a new car. Dan calling him out on this (and Carla, Elliot, Ted, Kelso, Cox, and even Turk agreeing with Dan) serves as a much-needed wakeup call to J.D. and he begins to clean up his act.

* OnlySaneWoman: The sanest of the principal cast and mostly everyone else who works at the hospital.

* WomenAreWiser: Nine times out of ten, any problems that arise in their relationship are caused by Turk. On the rare occasion that Carla is the cause of the problem, she'll get her way anyway. For example, an episode where Carla learned that she had to compromise with Turk instead of making all the decisions herself ended with her getting the car she wanted anyway; that's right: in the end, Turk was the one who made the compromise.
