Rick returns to the prison and tells Maggie and Hershel that Carol killed Karen and David, and thus he sent her off. Meanwhile, in the quarantined cell block, Hershel continues to care for the sick, with the ailing Sasha and Glenn assisting him. As the conditions of the infected worsen, many succumb to the flu and reanimate as walkers. Despite their dire situation, Hershel remains optimistic and comforts the other people in the quarantined area. The reanimated quickly proliferate and overrun the cell block, and Hershel, Glenn, Sasha, and Lizzie fend for their lives. Hearing the gunshots inside the prison, Maggie rushes to the quarantined zone. Meanwhile, the exterior fence gives way to the press of walkers, whom Rick and Carl kill using automatic rifles. Maggie manages to enter the cell block by shooting the window, eliminates the remaining undead, and rushes to her father's aid, while Hershel retrieves a breathing apparatus for Glenn, who is close to death. As Carl reassures his father, Daryl's group returns, and Bob administers medicine to the remaining infected survivors, including Glenn and Sasha. Hershel returns to his cell block and breaks down in tears. Later, outside, when Daryl approaches him about Carol, Hershel advises that he should speak to Rick. Michonne and Hershel leave the prison to dispose of the walker corpses. As Rick and Carl continue to tend to their crops, the prison is revealed to be observed by The Governor.
