This episode confirmed my biggest fear: I'm bad at focusing on audio stories, and will have to choose when to listen carefully.
As far as the story goes, I'm happiest to see that they're doing some character rehab for Marla McGivers.
They don't seem to be doing similar rehab for Khan himself, which is fine by me, but they are highlighting his ability to turn on a dime and go full tyrant at the drop of a hat.
Usually they would have saved that gritty stuff for DS9.
