Character mistake: 23rd minute. Jack meets the female assassin in Anderson's apartment. She demands that he show his credentials. Jack says he's with CTU on a provisional basis and therefore he has no badge. The agent that came with Jack confirms that. Yet, in the 13th episode (minute 14) when he enters the sports shop with Audrey's husband, he shows his CTU badge to the owners in order to prove that he in fact is a federal agent.
Character mistake: Near the start of the episode, Curtis asks how many square miles are affected by the blackout, and is told "approximately 8." A few minutes later, Sarah states that the blackout area is "everything within an 8 mile radius." These are vastly different amounts. An 8 mile radius would cover approximately 201 square miles.

Character mistake: In the scene where Chloe uses traffic video to get the license plate number off the van that takes Jack and Dina Araz to Habib Marwan, Tony is seen calling the field teams with the plate number, saying that it's "Charlie-Victor Alpha-Three-Two-Two." But the plate reads "6CVA322" so he should've said, "Six-Charlie-Victor-Alpha-Three-Two-Two."
