Day 8: 12:00 P.M. - 1:00 P.M. - S8-E21
Character mistake: When Chloe is talking to Arlo about the call Jack made to Meredith Reed, Chloe says that the call was made to Meredith's cell phone. But at Meredith's office, a coworker tells her the call is waiting (implying Jack called the office instead of Meredith directly), and once in her private office, she picks up the receiver of her land line. With all the phone tracing technology CTU has at its disposal, Chloe should be able to distinguish between the two.
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.
