A vessel overtakes the ship, however; Jinny married a genius scientist who has developed a revolutionary faster-than-light drive. Only one experimental ship exists, capable of carrying ten people; aboard are several Conrads, including the domineering Richard, Jinny, her husband, and Evelyn, who has aged faster than Joel because of time dilation. She is now 19, and explains that she persuaded her grandfather into coming to get him. Conrad proposes an evacuation plan, shuttling people to their destination planet nine at a time. Joel realizes that Conrad is lying; he only contacted the "Sheffield" to obtain needed supplies and has no intention of returning. The businessman needs to establish control of the colonies and cannot spare the time. Conrad is defeated and the faster-than-light engine is transferred to the "Sheffield".
