Years later again, Caesar (the son of Zira and Cornelius), MacDonald and Virgil travelled to Breck's ruined city to search the archives for recordings of Caesar's parents. They located the tape labelled 'Proceedings of the Presidential Commission on Alien Visitors, 1973' , which included Cornelius' testimony before the Committee (though his mention of the name 'Aldo' had apparently been edited out) and secret recordings of Zira made by Dr. Hasslein.
