While clearing the prison Rick and Tyreese encounter a closed door to the cafeteria. When they burst in they find 4 other survivors, Dexter, Andrew, Axel and Thomas Richards.
They bring the rest of the group inside the cafeteria where they eat for the first time in quite a while. But unlike Rick's initial thought, the 4 new survivors reveal they are inmates not guards. Dexter, killed his ex-wife and her boyfriend; Andrew was a drug dealer; Axel committed armed robbery; Thomas Richards says "Tax Evasion". It is also implied that Dexter and Andrew are in a homosexual relationship. Then Dexter shows them around the prison, they reveal they had to use the freezer as bathroom after the buckets were all filled with excrement.
