By the way, McCoy's behavior in Tholian Web was about on the same level. And for that matter, in Paradise Syndrome too. Unprofessional, non-supportive, inexcusable in a senior officer.
of course, in both those episodes Kirk isn't there to keep him in check. He always acts like an ass when kirk's not around. (well more
of an ass than usual)
Like that annoying co-worker who acts professional only when the boss is around.
i can imagine mccoy getting bad reports from people all the time, but since he's the captain's buddy and a good doctor he gets to stick around. perks of being in jim's good old boy club
