For an episode filled with bullets through zombie brains, it was Glenn’s head I was expecting to explode as secrets rattled around inside it like time bombs. Lori is pregnant, there’s a barn full of walkers at least no one told him that Hershel was planning on kicking them all out once Sophia is found.
“Secrets” was mostly concerned with a sanctity-of-life issue that didn’t involve Lori’s decision whether to keep the baby. It’s Hershel’s Pro-Undead stance. His infected wife and stepson are getting fed wounded chickens from the hayloft, and that particular secret is spreading. Maggie wishes Glenn would stop calling them walkers—they’re still “Mom” and “Sean” to her, an attitude that was tested by a zombie attack at the pharmacy.
Hershel’s optimism, buoyed by the idyllic setting at the farm, seems beyond naïve, but hope and two daughters are all he has left. His anxiousness to see his guests on their way has everything to do with keeping the brains of the less-alive members of his family intact—a much better reason, I guess, than just trying to keep his daughter away from the Asian boy.
This reminder that the enemies are us, the zombies are our brothers and mothers robbed of their humanity, is one that movies have only been able to touch on, but The Walking Dead has revisited over and over: with Morgan, holed up with his son, unable to shoot his walker wife, or even abandon her; with Andrea having to put down her own sister; and now with Hershel’s Zombie Protection Program.
The hardest job of the apocalypse it seems, though, is Motherhood. Carol remains a wreck with her daughter missing. And Lori, after almost losing Carl, after seeing him hardened (“Everything is food for something”) and knowing he’ll hardly remember his prior life, can’t bear the thought of bringing another helpless creature into this terrible world, especially after discovering the secret of their impending homelessness. Her worries are practical—a baby’s cries put everyone else in danger. She frankly can’t see how human life remains much better than what the zombies have. But she can’t bring herself to go through with the abortion.
In the end, Lori divulges all her secrets and realizes that Rick already knew about her and Shane. It seems like we may get a baby after all.

Episode 7: "Pretty Much Dead Already"
Episode opens with Glenn revealing the presence of the walkers to the rest of the group, who promptly proceed to freak out. Maggie becomes angry with Glenn for not keeping the secret and ruins his hat in retribution. Dale gives Glenn his trademark hat as a replacement. Maggie later makes a plea to Hershel for the group to stay. She and Glenn also have an argument about the walkers, after which they eventually admit their feelings, kiss and make up.
Rick and Hershel argue, with Hershel demanding the group leave within a week. Rick uses the my-wife-is-pregnant card, but Hershel's not persuaded. Shane also wants the group to get the hell out of there because of the walkers in the barn, but Rick uses the same excuse to cool him down. However, Shane then becomes convinced that Lori's baby is his.
Dale takes off with Shane's guns to hide them in the swamp. Shane tracks him down and demands he give the guns back. Dale points his rifle at him and threatens to shoot. However, he backs down at the last moment, since he has no wish to become like Shane: he reveals that he knows Shane shot Otis and lied about what really happened. Shane heads back to the farm with the guns.
Hershel has Rick help him and Jimmy try to fish some walkers out of a nearby pit of quicksand and lead them into the barn with snare poles. He says the group can stay on the farm if they agree not to kill the walkers. They arrive at the farm about the same time Shane emerges from the swamp and hands out guns to other members of the group.
Shane sees the snared walkers and goes berserk. He yells at Rick and Hershel as they guide the walkers towards the barn, with the rest of the group and people in the farm looking on. He pulls his sidearm and unloads it in the chest of one of the walkers, demanding to know "Could someone who's alive just take that? Why is it still coming?" Hershel has no answer.
He finishes off the walker with a headshot, grabs a nearby pickaxe and breaks open the barn door. Walkers pour out, T-Dog, Daryl, Shane, Glenn, and Andrea form a line and open fire. Once the dust clears, one more walker emerges. Sophia. Rick finally steps up next to the others, pulls his six-shooter and kills Sophia with a shot to the head. End episode.
