Ever since "Picard" season one, I've been itching to see Starfleet during the time of the Romulan evacuation, when the vast majority of their resources have been redeployed to support that mission. I never expected it to be this show that did it. It's interesting to hear that there are A500 synth units supporting the Federation member worlds - it's probably a good thing that only the units on Mars were hacked, as far as we know.
Thematically, things are really starting to come together, with Dal and the crew learning to contribute to the mission rather than take control of it.
I think I'm pretty happy with this resolution to Zero's arc - their new body seems fitting.
Pretty good for a table-setting episode. The most significant development was taking Wesley's omniscience off the board, which probably had to happen for the rest of the season to have any stakes.
