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.


Spoilers galore for PIC

They created a spin-off Borgs collective with one of the main characters from S1 as the queen. They were powerful but looked to cooperate with Starfleet to deal with a big space anomaly. And the season ends and nobody really knows what’s up. Are they now the only Borgs? Is this a hard reset and it was all a dream? There are some timeline shenanigans that could explain away everything.
And then S3 happens and we eventually find out the OG queen is hiding and masterminding a new plan that isn’t sending one cube to earth for a change. I think they never even question how the S2 Borgs fit into this. It is as though they never existed. What’s worse, they seemed to imply this old queen is the one Picard and Data defeated in First Contact and not the one that Janeway dealt with after that.
Swiss cheese is remarkably dense compared to the story PIC tells.
And it’s Star Trek. They will always find a way to expand on the Klingons. They’ll find a way to bring back the Borgs if they want to. What did the Burn do to whatever was left of them? That’s not an uninteresting question if you ask me. Their STSA-current facebook status? It’s complicated.
You have to watch out about that. Star Trek loves the Klingon like they love the Vulcans.
