The League reviews the surface of Mercury, seeing several structures. A mysterious figure is told that "He's arrived," before we cut to the planet Mercury in the year 1976. Jack Yaeger is investigating the Mercury base that served as a staging point for the Earth invasion we've witnessed in previous episodes. As Yaeger and a League colleague talk, we learn more about the villainous Chief Designer and his workings. The conversation continues, but then shots are fired, and Yaeger suddenly faces a surprise attack from a masked sniper. Using a projector, he's able to get the drop on his attacker, who he dispatches with a headshot. Investigation of the corpse reveals a journal with details on Yaeger...and pictures of Edward Borman. Back at his office, Borman receives an envelope from "Buck Rogers." When he opens it, bullets for the Lumiere pistol fall out...but it may be too late, as another assassin appears behind him.
