Definitely feeling some of the loony energy that Season 2 had in its finale with these events, not necessarily in a bad way. Though the semi-predictable twist of it was the Borg again does highlight how Season 3's insistance on outright ignoring the events of the first two seasons feels particularly sloppy right now. I can understand logically why they can't just reach out to the Jurati-collective for aid, y'know the friendly borg faction that arose from Season 2 that's controlled by Picard, Seven, and Raffi's old bestie Dr. Jurati? The events of the first two seasons still happened so they're still out there and it's just kind of frustrating that this doesn't even get a throwaway mention. Like "I wish we could reach out to Agnes for aid, but we've been advised that it's taking all her collective's efforts to keep that anomaly at bay for the time being, so she's unable to help us." Just something like that, a line.
This is kind of a small nit to pick I suppose, but it's just another example of the 'throwing out the baby with the bathwater' mentality this season has had towards the first two at times. They were flawed, sure, but I'd rather see them built upon than ignored.
That being said, haha, of all the attitudes to bring back from the first season, bringing back a favorite tertiary character for a few scenes only to murder them was not one I expected. At least Commander Ro was shown more care than poor Shelby. Hey maybe she survived? The feed cut out right after she was shot, miracles can happen!
The final scene was just such unapologetic nostalgia bait and goddammit I am a mark.
