Descent, Part II

TNG Season 7 Episode 1
Air Date: September 20th, 1993

Lore and Data, brothers working together. We learn that Lore has been experimenting with the Borg trying to create more artificial life. But instead of creating a positronic net like his and Data's he is trying to replace neurons in organic life with machine replicas. His experiments with the Borg go poorly so he decides to try to use Lt. Cmdr. La Forge's visor implant as another way to do the change. While Geordi undergoes "treatment", Captain Picard and Counselor Troi try to create a device that will restart Data's ethical program.

Meanwhile Cmdr. Riker and Lt. Worf remain on the planet to search for the captain's team telling the Enterprise to leave orbit and get away from the attacking Borg. They eventually find Hugh leading a resistance force and convince him to help them rescue his friend Geordi. They arrive just in time to stop Lore from killing Picard. Lore tries to escape but Data ends up disabling him and ultimately disassembling him.

The Enterprise itself was playing a cat and mouse game with the Borg ship. Doctor Crusher was left in command and was able to use the metaphasic shielding technology to hide the Enterprise in a nearby star and using a solar flare to destroy the perusing Borg ship.
