Other mistake: Earlier in the season Father Gabriel Stokes burns his clerical collar, but in the end of this episode he is wearing it again. Especially doesn't make sense, because he said he gave up being a pastor.
Other mistake: When Nicholas shoots himself, both him and Glenn fall with their feet facing the dumpster, and their heads facing the walkers. However, when they cut to the shot of presumably Nicholas being eaten, we see Glenn's head facing the dumpster. This does not make any sense. Glenn would have had to do a complete 180 turn before landing, or move around without being detected by walkers. In fact, the way they landed does not make sense at all. The fence seen when Glenn and Nicholas climb on top has also disappeared.
Other mistake: Eric gets shot while fighting with a group against the Saviors. Aaron carries him to a tree and leaves him so he can continue fighting. When Aaron comes back to check on him, Eric is gone and the gun is left behind. Aaron yells his own name instead of Eric's name. (00:33:30)
Suggested correction: He screams Eric, it just sounds a little odd so the subtitles got it wrong.
Other mistake: When Daryl is cutting open a walker in the woods to see what meat it ate while searching for Sophia he stabs the walker several times, but the knife is not bloody and it stays clean. (00:33:30)
Other mistake: In the opening scene when the cop stops at the side of the road & walks between the truck & car you can see there is no engine or transmission on the truck lying on its side. (00:00:20)
Other mistake: When Martinez shoots the grenade launcher for a second time the cross hairs are on the concrete wall of the guard tower yet the explosion does nothing to the concrete and destroys the top of The Tower.
Other mistake: In Woodbury, on the street, while Andrea talks to the Governor, we can see everybody wearing jackets and orange, red and yellow trees, showing that the scene was shot during fall. According to the beginning of the third season, they had just passed through a hard winter. So it should be spring or the beginning of summer.
Pretty Much Dead Already - S2-E7
Other mistake: As Daryl carries a saddle toward the barn, in the far shot, there is no one around. The shot then changes to him entering the barn carrying the saddle inside. Suddenly we now see Carol coming around the corner, several yards behind him. Where did she come from? Unless she was already inside next door and saw him enter, she shouldn't have been there.
Other mistake: Most if not every time someone kills a walker in close proximity or repeatedly bludgeons one that is already dead with a blunt object and there is a CGI blood spatter effect (as opposed to a practical blood spatter effect), the blood magically never gets on the person's face.
The Day Will Come When You Won't Be - S7-E1
Other mistake: When Rick is on top of the RV, Negan peppers the roof with bullets from the inside, so that Rick has to run and jump onto the hanging walker. Negan's using a machine gun, so a lot of bullets, and the exit holes that are made, are visible on the roof. The softer material of the inside ceiling would have been really torn up, but when Rick gets back into the RV with Negan's axe, the ceiling is undamaged. (00:21:38 - 00:24:36)
Other mistake: When Gabriel is out by himself on the road and kills two walkers, he is wearing a white shirt. Blood is shown spattering everywhere, but his shirt remains spotless. (00:37:00 - 00:39:00)
Other mistake: When the Alexandria Group are at the Hilltop trying to convince Gregory to join them in their fight against the Saviors, we can see the actresses who play Michonne and Maggie trying to hold in their laughter. (00:06:02)
Other mistake: When the herd appear on the freeway walking around the corner it's the same footage used in the previous season, just before Rick and Michone drive the two cars at them connected by the cable.
Beside the Dying Fire - S2-E13
Other mistake: While the farm is being overrun, Hershel is out front with his shotgun constantly firing. He never reloads and would never had the chance to stop and reload that weapon with so many zombies on him. His shotgun appears to have infinite ammo at this point.
