In the TV series Scrubs, season 2 episode 3, the first time that Dr. Mickhead is spoken to by name, he's actually called Dr. Carlson (by Dr. Kelso). But then, for the rest of the entire series, they call him Dr. Mickhead. Why is this? Surely the creators had records showing that he was originally titled Dr. Carlson..
I mean, why not just call him Mickhead from the beginning? Or, if they didn't want to reveal the Dr. Mickhead character so early in the series, just have Kelso say his first name, or just not say his name at all (or even use a different doctor for that scene). Was Dr. Mickhead not thought of until later in the series?
So, ultimately, my question: In the TV series Scrubs, why was the actor Frank Encarnacao originally called "Dr. Carlson" (s02e03), but then later called "Dr. Mickhead" for the rest of the series?
