“Brothers”
While the Enterprise is hurrying to save a young boy’s life, Data suddenly seizes control of the ship and heads for an unknown planet. Data has unknowingly been called home by his creator, Dr. Noonien Soong. On the planet, Data meets Soong and, to his surprise, his brother Lore who was left adrift in space almost two years ago. Soong reveals that Lore is actually the first prototype and was deactivated because he turned out unstable. It was Soong’s intention to supply Data with an emotion chip, but Lore gets the chip and hurts Soong who dies briefly after. While Lore escapes, the Enterprise continues to the next starbase to save the boy. summary by Ex-Astris-Scientia
Uhm… It was interesting to watch Brent Spiner act three people at the same time. You have to agree it’s a challenge.
What captured me when I saw it for the first time was the mystery of course. Data on ruse? Come on! It’s a pitty this also was exploited later.
