Plot hole: Diana in her final scene is seen shooting her last bullets at the walkers that are offscreen, moving toward her, so suicide was not an option, meaning the walkers would have eaten her until she died, becoming a walker. And yet her body is completely clean when her son and Michone discover her in walker form. Blood free (even on her clothes) and fully intact, no chunks of her missing, no bite marks.

Starring: Jon Bernthal, Sarah Wayne Callies, Steven Yeun, Andrew Lincoln
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)
Carol: haven't had a chance to say, I'm glad you came back.
Daryl: To what? All this?
Carol: This is our home.
Daryl: This is a tomb.
Carol: That's what T-Dog called it, thought he was right, until you found me. He's your brother, but he's not good for you. Don't let him bring you down. After all look how far you've come.

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."
