Ro and B'Elanna fight as Hugh and Spock look on. Ro's words seem to reach her for a moment. Long enough for Worf to knock her out. As the Defiant crew weigh their options Spock takes things into his own hands, literally, and mind melds with the possessed B'Elanna. He finds himself in a hellish landscape for a brief moment until Worf breaks the meld. Spock runs off and with no other options Hugh suggests he assimilate B'Elanna. Deep in the Starbase Spock finds a door... a door which opens to reveal a gigantic monster emerging.
We grow closer to a Sela face turn in this issue. I think it is wise to keep her out of the main action this issue. There is some minor continuity here with Hugh mentioning the Starfleet project to reclaim assimilated Borg. Or as they will be known in season one of Picard, xBs. Worf has little to do this issue. The first half is dominated by the fight between Ro and B'Elanna and later the actions of Spock and Hugh. So not much room for Worf this issue. Even though it was a long time ago you'd think he would remember the details after getting beat up by a parasite possessed elderly man in Star Trek: The Next Generation Season 1 Episode 24 "Conspiracy".
seven out of ten.
