It was not until 2665 that Jesse did return to Titan. He came with his one and only heir, Caleb. Caleb had strangely silver hair, eyes and nails just like his mother had had. His mother was a Silver Assassin. Jesse had attempted to rescue her when he was on a mission to stop the Silver Assassins collecting precious methane from the far north of the abandoned Mars. Number Six (for that was all Jesse could find of a name on her to identify her at the beginning) was defected and showed excessive human emotion at spontaneous moments. She was sent on the mission and programmed to destroy herself upon finishing but because of the excess methyl isocyanate in the few remaining ice flows, her primary function waves were disrupted and although she suffered from mild dyspnea and lacrimation, she survived much longer than would have been expected of a normal human. She was though, of course, a Silver Assassin and much more adapted to ailments and such.
