Well, my concerns about SNW becoming 'too light' were certainly allayed this week!
1. Balok appears again! His character was a little goofy, but okay.
2. The medical camp was very evocative of the 4077th MASH, for those of us old enough to remember that show. Every time the computer called a new incoming transport, I could almost hear the PA announcement through the camp for 'incoming wounded' as well as that iconic MASH theme in my head.
3. At first, the dojo session between M'Benga and the Klingon reminded me a little of Worf providing instruction to ENS Seto in Lower Decks. (The TNG episode, not the series)
4. We learn a little more about the Popeye juice. It's M'Benga's own special recipe.
5. Loved the look of the Andorian character, and those black uniforms were evocative of the Andorian uniforms in Enterprise. It makes sense that some things we see in Starfleet should be influenced by other member worlds of the Federation, and not just Human designs. If they had wanted to, this episode would have been the place to introduce either Starfleet Marines or 23rd Century MACOs. I would have liked to have seen a little something 'culturally Andorian' from the character, rather than just being a Human in Andorian makeup.
6. A couple of very good lines of dialogue in this one: a) "This may be the Federation, but everyone is on their own journey." Truer words were never spoken. b) "I didn't start the fight, Chris. But I'm glad it started." Powerful stuff. M'Benga is standing out as the deepest character on the show, with the most pain between his daughter and the war. Some of his actions have been morally questionable as well, especially by Starfleet standards. It'll be interesting to see his character arc play out over the remainder of the show.
Another solid home run, in my book. Great episode.
