I don't have much to say on this one. It was alright. Nice to see La'an make some forward progress in her own issues. When I saw the flat planet going through space I thought for a brief moment we were going to get a Discworld parody/crossover. I didn't mind this diversion so much, given that it was grounded in some kind of reality, and continued the story we had already started much earlier in the series. I do think everyone should have caught imposter pike much earlier on.
