I honestly wasn't feeling this one as much as last week. Both the A plot and the B plot seemed to be somewhat...contrived.
The whole thing with "crewman Tyler" was obviously some sort of reference to Discovery's first season. People were predicting it as of the season premier because they reused the same actress. I was honestly hoping for a bit more of a slow burn along several episodes. Regardless, while I could see what was going to happen from a mile away, the story beats were rather predictable. Barring that is one head-scratching moment - why she saved Ed when the ship was under attack, rather than just leaving him to die and finding her own escape pod. At first I figured that perhaps she still believed he had actionable intelligence, but since she initially intended to kill him as soon as she was rescued from the planet that wasn't the case. Maybe it was - as Ed said - just because she wasn't faking it as much as was suggested. I did like the conclusion of the episode - their continued attempts to humanize the Krill as individuals even as the culture itself remains a cartoon - but it didn't make up for this really badly plotted twist mid story. It would have been much better if she was somehow knocked out and he rescued her and dragged her into a life pod.
As for the B plot, it was nice for Gordon to finally get some development since Season 1 treated him solely as a joke character and didn't really ever give him a plot of his own. That said, it sort of felt perfunctory on the part of the show, and like it was sort of came out of left field rather than being a logical development of the character.
I feel the same way. This one lacked energy that I liked last week, and it went back to kind of being boring.
