Watched it for the first time a few days ago and it felt weird to have that whole irrational ritual with the Vulcans. Like Kirk aptly notes, "I always figured [you choose your mates] very logically". The episode itself wasn't bad, I knew beforehand what really is McCoy giving Kirk in that injection - generally I liked (though not loved) the episode. Not loved mainly because it felt illogical to have Vulcans... mate like animals, to put it shortly. Yeah, I know the repressed, calm ones are the quickest to crack down, but "Naked Time" has done it (Spock breaking up about his mother) much better IMO.
