Another great one. I was genuinely worried for Saru during the episode, afraid that his rage might consume him, but I was glad the liberation of his people seemed to bring him to an apparent peace of mind. As we learned more and more about the Ba'ul, and how Saru's behavior became increasingly belligerent, I became increasingly convinced that the Ba'ul were in fact the Kelpiens' mature form, so the role reversal came as a big surprise for me. Granted, it was either one or the other, but when I set my mind on one of two possibilities, I won't keep thinking about the other.
Either way, when the crew eventually decided to transmit the sphere's Vahar'ai signal, I became very anxious about all the bad ways it might turn out, especially after seeing what Burnham, Tilly and Airiam recovered from Kaminar's history. I was under the impression that Saru's behavioral changes were indicative of how mature Kelpiens behave naturally, so I felt a great sense of relief when his people's liberation brought closure to him instead. In that way, thinking back to his outburst toward the Ba'ul, it now reminds me much more of a classic rage against the heavens and also of confronting one's toxic and abusive parents on the way to recovery from childhood wounds. Pike was right to remove him from the bridge due to his obvious emotional involvement, but it's also perfectly understandable why he was enraged.
At first I was very surprised at how readily the crew became involved in the situation, but as it reached its conclusion, it suddenly dawned on me that this was not at all dissimilar from what Kirk would've done in Pike's place. The thought that you can intervene in the affairs of a pre-warp society to eliminate the influence of a warp-capable third party and restore the natural course of their development is nothing new. Still, I hope this similarity won't also mean that we'll just forget about Kaminar forever. I'd really like to visit this place again to see where this goes.
As a shameless Tilly fan, I admit I was bummed that she, among others, took the back seat this week, but it's not a problem; this was Saru's story and he had to carry it on his shoulders alone, with the rest of the cast taking on a supporting role. I rather liked how his emotional development was contrasted with Culber not feeling like himself, something that I really hope we'll expand upon in the future.
