[Copying my post from the original thread and adding something to the bottom]
Christina Chong absolutely killed it, especially in that final scene. Imagine finding someone you can connect to for the first time in your life, and immediately lose them. It even makes someone who is usually very unemotional crack.
Also, Pelia is such a delightful character. Great addition to the show.
Other than that I’m not really sold on the episode. It’s over an hour long and it did feel (too) slow and meandering at times. And I feel as if it just existed to shove in Kirk once again (and once again in an alternate timeline scenario to stick to the Trek canon) and explain the postponement of the Eugenics Wars by some Temporal Cold War shenenigans.
Final nitpick: how can Spock exist in the alternate timeline if humans and Vulcans are enemies?
Others wrote about how it was interesting that La’an had to choose to keep baby tyrant Khan alive for the greater good (of the future paradise Earth). And I agree that it’s an interesting conundrum – but that was given so little space in the episode that it fell entirely flat for me. La’an found out early on that Kirk didn’t know Noonien-Singh but that plot point was dropped for 30 minutes and only brought up again in the final minutes. In that aspect it reminded my of “The Elysian Kingdom” last season where nothing happens for 45 minutes and the interesting stuff comes out of the left field at the very end of the episode.
Maybe I’m being too harsh (I’ll rewatch the episode in a couple of days together with a friend) but for now I’d say this was one of the weaker episodes of the series.
