I'm watching The Undiscovered Country again and it just strikes me as out of character for McCoy after Klingon Chancellor Gorkon is shot and McCoy is working on him and says: "Jim, I don't even know his anatomy." To me, that's not like McCoy at all. I would have thought Bones would have been able to pull a rabbit out of his hat as usual and for him not to be ready for alien visitors and be ready to treat anything from a scraped knee (do Klingons have knees?) to an allergic reaction to the food is just strange. Did Starfleet send them out unprepared? Was McCoy slacking as he got towards retirement? Was McCoy bigoted? Or was McCoy not prepared for Kirk to even ask the Klingons to dinner and never expected to have to treat one? Is that odd to anyone else?
