Jillia was the teenage daughter of a tenant farmer named Polar. When Alan Virdon and Peter Burke brought an injured Galen to Polar's farm for rest, Jillia watched over him and developed a fondness for the friendly refugee. Unfortunately for the young chimp, Galen never reciprocated Jillia's affections.
