Season 4, episode 05
- Hershel struggles to keep his patients and their faith alive.
Rick drives back to the prison after leaving Carol behind, clearly still conflicted over what has happened.
Meanwhile, in the prison quarantine zone, the situation is getting worse. Several civilians are now coughing up blood, while Hershel, Sasha and Glenn try to stabilize an older man by intubating him and using a breathing pump to regulate his oxygen. Hershel wryly tries to make light of their situation, but soonafter discovers another recently-deceased civilian, and takes the corpse out of sight so that the rest of the infectees won't see them putting him down.
Rick finally arrives at the prison and sees Maggie, who is the sole person manning the fence and clearing the walkers. Rick asks if everything is okay, and Maggie tells him she's not sure, but that Carl is safe. When she asks where Carol is, Rick tells her the truth about what happened, and Maggie reluctantly agrees that she would have done the same thing in his place.
Soon after, Maggie goes to visit her father in the windowed meeting room, and asks how Glenn is. He replies that the latter is just sleeping, and tells her to stay strong. Outside the meeting room, Glenn is standing against a wall and thanks Hershel for covering for him, as he didn't want Maggie to see him like that. Afterwards, Hershel tells everyone to lock themselves in their cells and begins closing doors, only for another man to choke on the blood in his lungs. Hershel and Sasha move the body to the meeting room, but the stress gets to him as he covers the body and stabs it.
Rick, who has come into the other side of the meeting room to get an update, sees this and asks Hershel how he's holding up. When the latter reports the situation inside, Rick tells him about what happened to Carol, leading to the latter having a near-breakdown at the revelation. He recovers and returns to the cell block, only to discover an extremely-weakened Sasha. As he moves her into a cell, a female corpse reanimates and begins to stir.
In the administration wing, Rick brings Carl a bag of food, but the latter replies that he wants to help. Rick tells him there's a task they could both do together.
In the infected cell block, Henry, the man Glenn is pumping air into, succumbs to his injuries, while Glenn himself begins choking on his own blood and passes out. Lizzie sees this and calls for help. When Hershel moves to assist, the female walker attacks Hershel. Another civilian saves his life, while another man, Noris, attempts to shoot the walker. The situation spirals out of control when Noris is bitten by his reanimated son, causing chaos as he keeps shooting at random.
Outside, Rick, Carl and Maggie are propping up logs against the prison fence when they hear the gunshots inside. Rick orders her to go inside and investigate, but soon after she leaves, the logs break and a segment of the fence caves in. Rick and Carl are forced to run to the inner yard.
Inside, Lizzie leads the reanimated Henry, who is still with the breathing tube inside him, away from Glenn in order to save his life. Henry tries to attack her, only to be pulled off and thrown off the catwalk by Hershel. He puts Lizzie in a cell with Luke and goes to retrieve a shotgun from Dr. Subramanian, only to discover that the latter reanimated. He mournfully puts Caleb out and retrieves the shotgun before killing three more walkers.
Outside, Rick and Carl run to a cache of weapons. Rick quickly tells his son how to reload an assault rifle, and the horde breaks through the inner fence. Together, the pair clear out the horde.
Meanwhile, Hershel sees Glenn's rapidly-failing condition, and realizes he can save him with the breathing tube attached to Henry. Meanwhile, Maggie breaks into the quarantine zone and kills the reanimated Noris before encountering her father struggling with Henry. She manages to kill Henry without puncturing the breathing pump, and together, Hershel and Maggie save Glenn's life by intubating him. The supply run group arrives soon after, and begins distributing medicine to the infected civilians.
The next morning, Rick and Carl go back to their farm and discover that more crops have grown, while Daryl asks where Carol is, only to be told to discuss it with Rick. Meanwhile, Hershel goes out on a run with Michonne, while Tyreese and Bob tend to the sick.
Outside the prison, however, a familiar threat is lurking...
- A Day in the Limelight: For Hershel, to an extent.
- Absentee Actor: Carol and Beth are entirely absent from this episode, while Daryl, Michonne, Tyreese and Bob only show up for a few minutes at the end.
- An Ax To Grind: Maggie uses an ax to chop the arm off a walker when it grabs Rick through the prison fence. She later uses the same ax to try and break into the quarantine area, though it doesn't work and she ends up shooting out the glass instead.
- And Then John Was a Zombie: Several, particularly Caleb. We also have Mr. Jacobson, Henry, and Noris, besides some unnamed Red Shirts
- As the Good Book Says...: Subverted - Hershel tries to read his Bible after the walker rampage is contained, only to break down sobbing at having lost several people, especially Caleb, with whom he had struck a close friendship.
- Big Damn Heroes:
- Maggie breaks into the quarantine area to assist her father when the deceased flu victims start to turn.
- One of the sick female civilians shows up out of nowhere to save Hershel's life after he's attacked by a walker. However, she's killed soon after when one of Noris' errant gunshots hits her.
- Bookends: The final scene of this episode closely mirrors the opening scene of the season premiere, with Rick coming out of the prison to tend to his garden.
- The Bus Came Back: The Governor.
- The Cavalry: Daryl, Michonne, Tyreese and Bob return to the prison at the end of the episode with the antibiotics.
- Character Death: Caleb Subramanian, three named Red Shirts (Mr. Jacobson, Henry and Noris) and more unnamed ones.
- Chekhov's Gun: Caleb's shotgun, which Hershel obtains and uses during the last few minutes of the outbreak.
- Chekhov's Skill: Hershel demonstrates to Glenn how to intubate and use an oxygen bag on a civilian whose lungs are filling with blood. Later, Hershel uses this same tactic to save Glenn's life after the latter begins experiencing the same symptoms.
- Contamination Situation: The sickness reaches its peak, with much of the episode focusing on Hershel's attempts to keep the quarantine under control, the sick people alive, and prevent anyone who succumbs from reanimating.
- Continuity Nod:
- Rick explains to Maggie and Hershel why Carol isn't with him when he returns from his supply run.
- The final scenes are almost a shot-for-shot parallel to "30 Days Without an Accident", with Carl asking why his father didn't wake him and Michonne going out for a run.
- The cache of guns stored near the inner fence appear to be the same ones Rick obtained from Morgan in "Clear".
- Creepy Child: Lizzie keeps this behavior, first drawing the zombified Henry away from an unconscious Glenn by baiting it and encouraging it along like a dog. She then rubs her boot over Glenn's bloodied phlegm.
- The Determinator: Glenn and Sasha both keep fighting through their own sickness to help Hershel tend to the others, which leads to Sasha passing out and Glenn nearly choking to death on his own blood.
- Due to the Dead: Hershel initially insists on this, wheeling those who have succumbed to the sickness away from the main quarantine area and holding a Bible over them while Glenn stabs them in the head to prevent them from turning. However, this ceases to be a viable option as the dead quickly begin to pile up.
- The Gunslinger: Maggie once again demonstrates her impeccable aiming skills by taking out a walker Hershel is struggling with from the floor below without hitting either Hershel or the intubation bag needed to save Glenn's life.
- Heroic BSoD: Hershel breaks down once the drama is over and Maggie finally tells him to rest.
- Ill Boy/Ill Girl: Glenn and Sasha.
- Idiot Ball: Hershel not locking the cell doors, while he may see it as form of keeping hope, it completely defeats the purpose of quarantine, doesn't improve moral and almost get's everyone killed.
- Improbable Aiming Skills: Both Rick and Carl get headshot after headshot when the horde breaks through the fence. Justified because they are employing machine guns, seeking to incapacitate most of the walkers to dispose of them later.
- Improbable Infant Survival: Played straight - while several redshirts die in the quarantine zone, Lizzie and Luke are put in a cell for their own protection by Hershel. Lizzie survives her brush with the zombified Henry.
- Instant Expert: After giving him a very short crash course on how to reload an assault rifle, Carl begins getting headshots left and right, and smoothly reloads the rifle on his first try (much to his father's surprise).
- Like Father, Like Son: Rick's realization that Carl is just as good a shot as he is - and then some, to the point that it unnerves him.
- Mauve Shirt: Caleb dies after appearing in a handful of episodes and receiving little characterization.
- Oh, Crap!: Rick and Carl's reaction when the walkers break through the outer fence.
- Out of Focus: The scouting party led by Daryl is mostly absent from the episode, and only shows up in the last five minutes to deliver the medicine.
- Point of No Return: Caleb recognizes that it's too late for him to be saved, and points Hershel in the direction of the weapons cache he's stored under his bed for when he and others turn.
- Percussive Therapy: Maggie is shown venting her frustrations by violently taking out the walkers on the fence near the start of the episode.
- This Is Gonna Suck: While he searches for the respirator, Hershel shouts to the patients to stay in their cells and to stay calm. Then he sees the respirator is on a walker in a precarious position over the catwalk.Hershel: Aw shit.
- Wham Shot: The closing shot revealing the Governor standing out of sight beyond the prison fences.
