SPOILER!

When they arrive at the house, Hershel instructs Patricia to prepare the shed to operate on the leg, therefore I doubt they stopped. I would rather have continuity that doesn't make sense than meaningless dialog and character that don't. I agree, the episode was pretty solid.

Maggie's story with the catatonic chick was retarded. Also Patricia, whoever the hell she is, is pointless too.

The time problem is only serious when they leave the bar and rescue the zombie bait on a stick, it is nighttime and they arrive at the farm at what looks like dusk.

Did anyone else notice the shootout in town occurred at night, but they guys don't get back to the farm until it is daylight? Continuity issues?
