Dina Araz has her loyalty tested by being told to kill Jack. It is revealed the gun was empty. This is the second time Jack has been involved in a test of loyalty with an empty gun. Day 3, Jack was told tested the same way when told to shoot Chase who had been captured following Jack. Jack did pull the trigger to Chase's head, however.

Michelle calls Chloe at home and asks her to come in. Seven (real-time) minutes later, Chloe has managed to change her clothes, apply fresh make-up, and get into CTU to start telling Edgar what to do.

During the scene where Dina Araz is taking Jack to the door of Fayeds from the front, she is holding him with her left arm, but when the camera cuts behind them she uses her right.

The helicopter that is shown in an aerial shot carrying Jack and Paul is clearly different than the one that they come out of at the landing pad.

A couple episodes ago the doctors at CTU told Erin that they didn't have the means to watch over her daughter while she was having one of her fits. Yet somehow they had the means to perform major surgery on Paul after he was shot. Last season when Tony was shot he was taken to the hospital. Since when do CTU agents have the benefits of personal on site surgeons? If the surgeons weren't on site, how did they get to CTU so fast? It would have had to have been in under 15 minutes time to get to CTU and prep themselves to operate and would have been much easier to just wait at the hospital for Paul to arrive.

When Tony calls in the van licence plate at roughly 8:56 he doesn't state the first 6 on the licence plate number and says only "CVA322."

When the pilot (John Hansen) talks to his abducted wife, he calls her Dory. She is credited on screen as Laurie.
