Internment - S4-E5
Continuity mistake: In the previous episode, Rick and Carol are shown hunting through houses for household drugs to fight the flu. They even make a mention that most of what they find expired a year ago, but to bring it back to Hershel anyway, and let him decide about it. But in this episode, Rick returns, talks to Hershel, and no mention is made about him bringing medicine. Considering how important it was to fight the flu with any means possible, Rick would not have let Carol drive off with the potentially life-saving drugs.
Pretty Much Dead Already - S2-E7
Continuity mistake: Deleted footage/special release only: Carol confronts Daryl about the boy being held hostage inside the barn (following Sophia's death), reasoning with him about pretending not to care when he truly does. At one point he moves to her, almost in her face. However, the following shot shows only a close up of Carol, implying they are standing feet apart, which is not the case. (00:24:10)
Answer: No, she actually tries to talk Rick out of it, but he's already made up his mind, minutes later when Daryl asks him about the location of his brother Lori says "he'll show you."
