Continuity mistake: In the shot near the end where you see Jack's family running away from the van, Kim is wearing sneakers. But until now, making abstraction of the other continuity error a few episodes earlier, she was wearing sandals. It can be seen in another scene afterward. (00:39:40)
Character mistake: Eli asks Rick, "Who was that guy I talked to? It was her father, wasn't it?" In the previous episode, Jack says, "I'm the last thing you will ever see if anything happens to my wife or my daughter." You'd think Eli would have registered what Jack said.
Continuity mistake: Mike Novick and Senator Palmer are outside the car at Dr Ferragamo's office building when his office explodes. As they get back in the car, you can see over the shoulder of whichever gets into the rear, passenger-side. There is no one in the driver's seat, but when Palmer says, "Let's go," the car moves off immediately. (00:30:25)
