When Arvin Sloan is shot, Jack Bristow attempts to operate on him and remove the bullet. We can clearly see that after the operation, Sloan's chest has not been shaved. Isn't it standard procedure in any operation to shave the selected area as to avoid the risk of infection from a skin hair that would fall inside the cut?
In the shot where the helicopter carrying Lindsey and Lauren to Camp Williams flies overhead, you can see the clear blue sky. But in the shot inside the helicopter, it looks like they are flying through clouds. Everything is white when you look through the helicopter windows.
Marshall leaves his computer terminal with the NSC information he was trying to hack into on Camp Williams when NSC agent Lauren enters the room. Isn't there some sort of CIA protocol for leaving classified information on one's screen when they leave their work station?
Campbell(To Sydney): Your personality profile revealed your one major weakness: empathetic suffering is harder for you to sustain than physical torture. So... thanks for caring.
Michael(About the storage container): The fact that you're even letting me see this place, means it's not your only one. Is it?
Jack: You're smarter than you look.
The opening sequence appears directly after the previous episode recap, in this episode, as opposed to appearing after the opening few minutes of the actual episode.
This is the first episode to show the "Created by J.J Abrams" part of the opening credits, over the top of the episode footage. Before, it was against a black background.
