I thought this episode walked a really fascinating line in its approach to exploring the lived experience and cultural significance of mixed identities. Having the ancient alien species misinterpret Spock's Vulcan DNA as an anomaly/pathology was a risky move from a writing perspective given the potential for reproducing language and ideas associated with eugenics. But doing so allowed what what I thought was a more robust examination of Spock's character and his relationships, by way of separating one half of his identity from the other and seeing what happens (like a smaller scale of Community's excellent "Remedial Chaos Theory," which examined how the study group might be affected by the temporary removal of each group member in turn).
There was plenty to laugh at, of course. Ethan Peck could easily have gone too over-the-top in playing Spock's surge in human emotions, but I think he threaded the needle really well in allowing through just enough Vulcan "muscle memory" (as it were) to tamp down the humania -- and he still managed to be extremely funny. And Anson Mount as always shined with his subtle (and hilarious) comic timing as the host of the engagement ceremony. Watch the way he snaps his fingers when T'Pring's father asks for more Tevmel --and how he continues on in wide-eyed stride on his way back to the group once Spock starts admitting to his "condition." Mount is a performer who knows how to blend into the scenery rather than chew it -- a distinct quality in a Star Trek captain and a consistently funny one to boot.
But what really made this episode work for me was the heart in addition to the humor. I have a friend who remarked earlier this season that she doesn't understand why Star Trek is so obsessed with Spock's human side; she's much more attracted to his Vulcan side and is confused at what she sees as the constant efforts to make him "more human." I can see her frustration, and this episode certainly turns into that skid a bit. But the show isn't fantasizing or daydreaming about a Spock that's fully human -- it's using the idea as a tool to understand his fuller and more complex identity, and to celebrate what makes Spock Spock. And I absolutely shed tears when Spock came clean to T'Pring's parents about his condition, not just out of personal pride but as a way to express affection and appreciation for his human mother. What a wonderful moment.
And I think this episode's true strength was in depicting how everyone in Spock's life understood that being made "more human" didn't make him better or more "fun" or more "relatable." Not once did anyone murmur to anyone else something like, "Are we sure we want to fix him?" (which I could easily see Dr. McCoy saying, for example). Instead, everyone understood fundamentally the unique value of Spock's half-human/half-Vulcan identity, and went to great lengths to bring it back. It might have been a bit corny to funnel that through Nurse Chapel's romantic feelings for him, and having her have to admit those feelings to an ancient alien species -- but it was smart, too. (And seeing her tell the Vulcan Science Academy that she didn't think their fellowship was ready for her made me literally pump my arm, by the way).
Another solid Spock-centric episode in my book. I look forward to reading what everyone else thought!
