Day 3: 7:00 A.M.-8:00 A.M. - S3-E19
Trivia: The website for Sylvia Imports which David Palmer must use to provide Stephen Saunders with a list of the 42 overseas agents actually exists. On it is written: "Sylviaimports.com - A Big Thank-you from the crew of 24. Thanks for watching, we love making it for you, and yes, we did get picked up for Season 4."
Chosen answer: Nobody knew, not even the writers, until at least halfway through the season when they were writing the end. They wanted to keep all options open.
