Okay let me just make this brief since I don't wanna spoil anything, but the story is just a way to close off the show in first inspector (following season). This season is meant to make you understand the new cast in sybil's world, not to be closing ends of what happened during the time skip. Everyone we previously loved was imprisoned or demoted to enforcers so we can't expect to see them have jurisdiction in the show anymore as inspectors.
After watching this please watch First Inspector. First inspector gives you some closing notes on the show, with maybe more to come in the future. So please watch that because it gives you a better take on the new cast and some ties to loose ends.
