Data, in his search for Lore, resigns from Starfleet and ventures to the Academy. Data manages to enlist the aid of Chief O'Brien. Together they search Farius Prime, a world the Chief is very familiar with, for clues to Lore's whereabouts. They are soon attacked by Klingons but are saved by Geordi La Forge. On Orion they confront those who gave Lore technology, and Data uses aggressive means to get the information he desires. They find a huge space station and onboard are confronted by Klingon Korath. Lore suddenly snaps Korath's neck from the shadows. Part of the space station detaches as Data has Geordi beamed away. Lore removes Data's head and on the bridge of his ship we see assimilated Klingons.
This story is... quite messy. Lore says he deliberately wrote a mystery to get his brother's attention... but it just feels like a fetch quest with little pay off. Orions, Klingons... nothing of real substance. The confrontation between Data and Lore is very brief, all too brief in my opinion. Geordi shows up to save the day... then does little much but worry Data is going too far in his quest of locate Lore. It feels like things we've seen before on TNG.
