This segment recounts Yuri Leonov’s final mission as a UN flight program operative. Yuri, a married man, departed on a new assignment, only to be inadvertently sacrificed for scientific research when his flight was directed to investigate a gravitational anomaly. He asserts that his last memory involved observing the anomaly up close before returning to Earth as one of the alien invaders. The flashback also introduces Colonel David Lawrence, Yuri’s mission commander on Earth and close friend. Lawrence is identified as the long-haired man who turned Ryu into a spy. Notably, Lawrence had opposed using Yuri’s mission to investigate the anomaly, highlighting the complex personal and professional dynamics surrounding the incident.
