The very first in "The Walking Dead" spoilers is that another character has gone crazy besides Rick. No, it is not the Governor.
At the star of season 3, episode 12, Rick, Carl and Michonne are driving into town to get supplies. They go to the police station where Rick used to work, but the armory is completely cleaned out. They decide to check some stores and bars where Rick signed permits to see if they have any weapons.
While the group walks through the town, they see a pile of burnt bodies with painted yellow arrows on the walkway. As they follow the arrows, the message "No guilt, you know that" has been painted on a wall. The middle of the street has several traps and they encounter another painted message that reads, "Turn around and live." Of course, that does not stop them and they continue walking. They find inside the booby traps a live bird or rate that is caged.
Soon, they encounter a walker, but before they know it, the walker gets caught in a trap. Then they hear a gunshot and the walker collapses.
They see a man wearing a mask point his weapon at them and he tells them to drop everything and leave. He wants them to abandon their guns, shoes and Michonne's sword. However, they are not going to be run off that easily. Rick tells Carl to go and a shoot-out begins, but then as Rick is reloading, he disappears, then suddenly Rick is pinned down. Carl ends up shooting the masked gunman in the stomach just in time.
