Cal MacNannovich, along with the other survivors of Platform One, was later kidnapped by the Elth of Balhoon, who believed that they hadn't tried to help the Moxx of Balhoon and had abandoned him to die. They were rescued by the Doctor, and not only forgave the Elth for kidnapping them, they offered to help him. (DWBIT: Reunion of Fear)
