Visible crew/equipment: When Maggie is in the pharmacy looking for abortion pills and is attacked, the camera cuts to Glenn twice before he rips the shelf from the wall to save her. The first time, behind him you can see that the glass next to the storefront door is empty. In the second cut, you can see someone standing on the steps. It looks like Melissa McBride.

Continuity mistake: When Daryl is driving the hospital van, it shows that he is going to land upside down, on the vehicle's roof, when he drives off the parking garage. In the next scene, the vehicle lands on its wheels, as if it has done a complete front flip. (00:30:00)

Trivia: Eugene is looking for his missing girlfriend, "Stephanie." Princess visits him. He shows her his pinboard with strings attaching clues. He's found out plumber Roman Calhoun, was the last person to see her and tracks him down to a dodgy outfit at "1634 Racine." This is the home address in "The Untouchables" (1987 film about the capture and imprisonment of Al Capone, starring Kevin Costner & Andy Garcia), of Jimmy the good Irish cop, played by Sean Connery.

Answer: The walkers could have knocked them down more than once. There may have been another wave that knocked down the fence earlier and they're going to put it up again soon.
