Isolation episode is a study in group psychology. The main story of a zombie flu creates stress for the zombie Apocalyptic survivors. The over populated and cramped prison conditions are the perfect incubation environment for a disease. Who do you isolate? Do you help the infected? The environmental stress is causing the characters to mentally crack! What will the survivors do if rational thinking devolves into the irrational logic? The second main story build up is down the road there are even greater number of zombies. Could be caused by the flu? There is the possible zombie wave hitting Rick and the survivors at the prison. A building stress, and story buildup for the stories climax is coming! The viewer will become enthralled with the story as the build up becomes stronger and stronger. But the story writers are taking their sweet time. 6 out of 10.
