In terms of the concept, this one is right up there with “Whispers” as precisely the kind of unsettling/creepy thing that I really like. The execution in that one was generally better, I think — I feel like they never fully realize the creepiness in this one the way they might have — but it’s still a solid episode.
Some interesting stuff going on in this one! And some really fun performances, as well. I did feel like the conclusion to the B plot, with the proto-universe, was…weird. They just…left this proto-universe, whose expansion threatens the station, in the Gamma Quadrant? Is it gonna keep expanding? I have a lot of questions!!!
