I'm not sure if it is going to be this episode, but thats what I was told that will be happening in the future...
A herd of zombies attacks the prison while Rick’s group is separated. With the generators running, The Prison alarms are blaring and attracting walkers from all over the countryside. The groups consist of: Rick, Daryl, Glenn, seeking out the generators with the help of inmates Axel and Oscar; Hershel and Beth locked into a cage for their safety; T-Dog and Carol, running for their lives; and Lori, Carl, and Maggie also running for their lives.
The first to die is T-Dog. He suffers a walking bite to the shoulder. In an act of bravery he sticks with Carol, determined to get her to safety. The bite is a one way ticket on its own, but the way he dies is truly gruesome. With the route ahead blocked by walkers, T-Dog runs full steam ahead managing to knock back the walkers and open a brief window for Carol to escape.
The second death comes towards the end of the episode. Lori goes into labor and attempts to deliver the baby. At first it appears she might be able to deliver without a cesarean, but then she begins bleeding profusely. With no way to stop the labor or get help, Lori comes to a decision. Maggie must cut the baby out of her. Lori accepts that she will die in the process. With Carl looking on, Maggie cuts the baby from Lori’s body. Lori dies in the process. In a very emotional sequence, Carl decides he should be the one to put the bullet in his Mother’s brain to prevent her from coming back and we flash to season two when Rick and Carl were sitting in the barn and Rick told his son “No more kids stuff. People are going to die.”
The end of the episode is absolutely heart wrenching. Rick and his group arrive at the separate part of the courtyard from Maggie, Carl, and the Baby. As they draw closer it becomes more and more evident what has transpired and Rick begins to absolutely lose it. It is a stunning portrayal of grief by Andrew Lincoln and will reach through the screen and squeeze the ever-loving tears right out of your eyeballs.
-Someone is still sneaking around the prison, stringing up mutilated deer parts to lure walkers in… should be obvious from the first couple shots that it's not Merle or The Governor.
-Glenn and Maggie have been getting it on in the guard tower… Daryl's response, "you comin'?" ...um...
-T-Dog's edit takes a sudden turn from INV to CPP. Not a good sign. Axel and Oscar want to be part of the group. Rick is against it. T-Dog is for it. Rick has his way for now.
-Back in Woodbury, Michonne does some detective work, notices blood and bullet-holes in the newly acquired military vehicle. Since when are walkers carrying guns? The Governor tries to sweet-talk her like the politician he is, but she's not buying it. Michonne wants to get the hell out of Woodbury, go to the coast, find a boat. Andrea is a sucker for bad-boys though and wants to stay with The Governor. Merle asks the governor for permission to go look for his brother.
-Back at the prison… it's all smiles until suddenly walkers appear everywhere inside the fences. Beth and Herschel go in one direction. Maggie, Lori, Carl are headed off by walkers in another direction. T-Dog and Carol are left behind and a walker takes a big juicy bite out of T-Dog's shoulder. Rick, Daryl, Glenn clear a path through the walkers. Prison sirens go off, attracting more walkers. Lori conveniently chooses now to go into labor, deep inside the prison.
-Drop your buff, T-Dog, the walkers have spoken... or grunted... or chewed a hole through your neck, or whatever it is that zombies do. That's what happens when you "pull a Dale."
-Rick and crew reach the generator room for the siren, with Axel and Oscar in tow. And the mystery saboteur is… Andrew? Well if they don't die on screen, they're not really dead. A fight ensues. Oscar finds himself with Rick's gun, holding both Rick and Andrew at gunpoint. He shoots Andrew and hands the gun back to Rick, proving his loyalty (which poor Axel has been trying to do awkwardly and unsuccessfully all episode). Daryl totally had the situation under control though.
-It's gonna be a C-Section (what did I say about foreshadowing), and it's going to be up to Carl to put a bullet in his mom's head before she turns. He does this off-screen.
-Daryl finds T-Dog's buff. No sign of Carol. The remaining survivors are reunited as Maggie and Carl emerge with the baby. Rick breaks down.
