With this episode, Jack Bauer has thus far failed to sacrifice himself three times. He left Fayed's hideout when CTU tried to trade him for Assad, Philip didn't pull the trigger when Jack traded his life for his nephew, and in this episode, CTU prevented Jack from blowing himself up while trading Audrey for the nuclear component.

This is the second time Karen Hayes has had Bill Buchanan fired from CTU.

Jack leaves a message on Buchanan's phone with details of his location. He also says that Bill "has been a good friend". Jack first met Buchanan on Day 4 when he took over from Michelle as head of CTU. At the end of the day, Jack's death was faked so he could hide from the Chinese. He returned (18 months later) on Day 5, where Buchanan was still running CTU but at the end of Day 5 he was captured by the Chinese and put in prison for another 18 months. When he returns on Day 6, he works with CTU for a few hours. So just when did Jack Bauer and Bill Buchanan have the time to become "good friends"?

When the agent talks to Karen about the fact that Fayed had already been in custody, the agent shows a video with Tom's ex-chief of staff making his confession. On the video, a timer shows its progression, starting at 4:40, and the agent says that the conversation went on for 20 minutes. Yet when he shows the incriminating part, the timer on the screen, less than a minute had transpired. (5:33).
