This rewatch has been illuminating. I forgot this episode existed.
Spock and T'Pring accidentally switch bodies while performing a katra ritual to get to know each other better. Of course, the body switch couldn't happen at a less convenient time. T'Pring, in Spock's body, is pressured into negotiating with the R'ongovans, testy aliens the Federation wants to admit. Spock, in T'Pring's body, must work with a Vulcan patient who has rejected logic. Neither has the skills to do what the other can do, yet they muddle through by pretending to be the other person, thereby learning to see things through each other's eyes.
The theme of seeing another's point of view is also presented in the subplots. Una and La'An indulge in "Enterprise bingo," a risky game played by lower ranks. Pike figures out that the R'ongovians aren't trying to be difficult; they just want to be heard. And, after being mocked for wearing a stereotypical fisherman's hat, M'Benga goes fly fishing just to give the doctor something to do.
I'm starting to understand why many fans enjoy the series even though it doesn't feel like the prequel it's supposed to be. SNW is definitely it's own thing--a somewhat silly, off-beat show that moves the comical aspects of Star Trek front and center. The original series (TOS) had plenty of off-beat episodes--space hippies, Alice in Wonderland, space gangsters, and so on--but those episodes provided comedy relief from the serious episodes about space exploration and sociopolitical commentary. SNW is all about offbeat stories with a dash of seriousness. It reverses the polarity, so to speak, of previous Star Treks.
That's not a bad thing, but it takes some getting used to. Una and La'An behave in a totally unprofessional manner by playing a game they have just punished two ensigns for playing. Meanwhile, T'Pring/Spock cannot manage the negotiations herself, so Big Daddy Pike comes to the rescue. And Spock/T'Pring slugs the recalcitrant patient, which solves nothing.
Muddying the waters is the show's superficial resemblance to TOS. The episode begins with a faithful recreation of the Vulcan marriage ceremony from "Amok Time"--the gong, the bells, the koon-ut-kal-if-fee challenge ritual. As in the earlier episode, Spock must duel with someone to marry T'Pring, but this time his opponent is himself--his human half versus his Vulcan half. It's a dream sequence, of course, and one that goes on too long for no reason other than to pay homage to the original episode. Even the title of the episode is a riff on "Amok Time." Such things may thrill fanboys but offer little substance.
Similarly, Spock's friendship with Nurse Chapel is introduced, leading into their pseudo-relationship in TOS. It's difficult to reconcile that relationship with the playful friendship shown here, and with Christine's varied love life that includes both men and women. How in space did she go from an outward, assertive woman who plays the field to a milquetoast who pines for a man she can't have? All in a few years?
The episode also violates canon by having Chapel assist Spock/T'Pring with the Vulcan patient. In "Amok Time," Chapel does not know T'Pring and is visibly hurt when Spock describes the latter as his wife. But whatever. If you pretend that SNW is its own thing without any connection to TOS, everything works just fine.
The problem is that SNW wants it both ways. It wants to be a prequel and to only superficially include canon. It wants to have far-flung space adventures but not portray its paramilitary officers as seasoned professionals. And it wants to keep Star Trek's optimistic vision of the future without providing a credible treatment of that future.
