Sometimes the time travel confuse me, in this case, the new Borg queen pretend to create a new collective, now, the third season Borg queen is the old one, right?
So, what happend with one and the other collective? The new one affected the other one?
Edit: I add an spoiler warning in the title.


They’re separate queens and separate collectives/cooperatives.
The Jurati Cooperative is, as of the end of Season 2, guarding the spatial anomaly that formed in the beginning of S2. They’re completely absent from the third season. Which I can understand since S3 was a fan-service reunion (which I loved) and there just wasn’t room in the 10 episodes for them.
The queen from S3 is the same one from VOY: Endgame and First Contact and part of the same collective since they were first introduced in TNG.
AFIAK, no, they had no effect on each other. The alternate timeline queen (that turned into Queen Jurati) was not the same queen seen in S3 or elsewhere. That queen was from a 2401 that no longer exists. She and her cooperative only exist because they went back in time and took the long way back to 2401.
So Jurati Cooperative is in a different timeline and both are intact or they are in the same universe?
They are both in the “prime” Star Trek universe, but the “classic” Borg Collective is dead, leaving only Jurati’s splinter faction (as far as we know).
This is what I was thinking, the Borg was fully destroyed after season 3 of Picard?
