Season 5
Frank Flynn, Jack Bauer's alias had made a cover story that he worked in The Albatross in Alaska the year before Day 5. Derek Huxley claimed that one of his friends' brother worked in the same platform, and never heard of a Frank Flynn. Jack feigned that the workers there used nicknames and asked Derek what was his friends' brothers name.
