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.

Genres: Horror
Continuity mistake: On the roof all the survivors are discussing their escape plan while T-Dog is lying down injured by Merle. In the next scene people are wearing rain coats and covering their bodies with the walker's remains as Rick proposed. T-Dog has taken off his cap and looks fine. Rick gives him the handcuff keys to free Merle. In the scene after, while Rick and Glenn went out the streets, the others go back on the roof to watch them from above. Nobody is wearing a raincoat and also T-Dog is in the same condition as before, lying down with his cap on. (00:24:00 - 00:31:15)

Trivia: When Michonne and Daryl are walking toward the gas station sign, above the word diesel it spells out HELL in upside down numbers. (00:08:59)
Question: Why does Lori tell Daryl that Rick will show him where his brother is but then 10 minutes later tried to talk Rick out of going?
Answer: It's not shown, but I think Lori is suffering from some sort of PTSD due to thinking her husband had died, having an affair with Shane and of course the zombie apocalypse as well! This isn't the only time she contradicts herself so it kinda backs this theory up.
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."
