Plot Synopsis
Allen is lifted out of the prison block by Rick, Tyreese, Dale, and Axel. Despite protests from the other survivors, Rick cuts Allen's foot off to save him from infection. Hershel then saves Allen's life by tying Axel's hair to Allen's arteries to stop him from bleeding to death. Allen passes out and is carried into an empty cell to rest.
Carol is upset over the news of Allen's injury, and wants support from Tyreese. She proceeds to the gym and sees Michonne giving Tyreese oral sex through the gym's window.
Later in the prison, Andrea observes Michonne talking in her cell to an imaginary person. Andrea confronts Michonne about this but Michonne says that she doesn't know what Andrea's talking about.
