Corrected entry: When the governor first puts his eye patch on it is on his left eye. When he turns around his eye patch is now on the right eye and stays this way throughout the rest of the season.
Corrected entry: When Tyreese and his group are in the woods before they find the prison, Ben's mother gets bitten on the arm, but she starts limping and needs to be held up by her husband.
Correction: Ben's mum begins to limp because she gets caught in something as they're running away from the walkers.
Corrected entry: When the Governor is teeing off on top of the walled barricade, we can see the tree line in the background is far away at the edge of The Other Side of Woodbury. After Merle has a chat with the Governor, we now see the trees are magically a lot closer.
Correction: The trees were the same, they are different distances depending on the angle and eye coordination.
Corrected entry: Carol's head wrap is well intact as she and T-Dog find escape down a hallway during the alarm system chaos. Soon they run into another pack of Walkers, and he sacrifices himself in order to save her life. As she runs past him, and toward another escape door, her head wrap is still intact as she opens the door and runs off. Later, when Rick and Daryl happen upon that same hallway, and T-Dog's remains, Daryl glances downward, however, and picks up the same head wrap, now covered in blood, alongside her bloodied knife.
Correction: We do not see what Carol does after she leaves. It is possible that she returned and left her head-wrap. Also, her knife was found later on in the episode.
Corrected entry: In the corner cafe, Carl grabs his family photo and then he and Michonne attempt to sneak back out to safety, but get run in by Walkers. As she downs a few she and Carl run the other way. However during the escape, he accidentally drops the photo in the middle of the walkers as they reach the front doors to safety. Outside, he insists on going back for his family photo but Michonne tells him to stay put... She will get it. Moments later she returns holding the family photo. Since the photo was dropped near the front doors, which is occupied by the Walkers, this would have been impossible for Michonne to have accomplished.
Correction: This is not a plot hole. We do not see what Michonne does to retrieve the photo. She most likely killed a number of walkers to get through - we know she can handle a large group of walkers on her own so she most likely fought her way through.
Correction: When we see the Governor put his eye patch on it is his reflection, we see which is why it is on the left.
