Continuation of the amazing Scorpion episode. Seven of Nine, who will be a main character for the rest of the series, is introduced as a member of the Borg collective (she is reverted back into an individual in the next episode). The cube and Voyager are traveling at high warp, fleeing from the species 8472 ships. The cube and Voyager are also developing the new technology for the Borg. During an 8472 attack, the cube is destroyed, but some drones and Janeway are beamed off the cube onto Voyager. Janeway is incapacitated, so Chakotay breaks off the alliance with the Borg and seals the drones in the cargo bay. Voyager continues to develop the technology. They eventually open a singularity to the 8472 realm, and enter their realm. Voyager destroys many 8472 ships with its new technology, so all the 8472 ships leave the Delta Quadrant, ending the war. After Voyager returns to the Delta Quadrant, Seven of Nine attempts to take over the ship and return the drones to the Borg. Chakotay depressurizes the cargo bay and all the drones are sucked into space, except for Seven, who is already in the airlock. Chakotay manages to fiddle with Seven's brain until she finally collapses and ceases to take control of the ship. Great episode!
