In last week's mid-season premiere, and subsequently talked about on AMC's Talking Dead, as well, there was only one zombie kill in the entire episode. That was certainly not the case this week. As the episode opens, Lori is in her overturned car with a pair of walkers outside trying to get in. As one of them is letting the broken glass from the windshield tear away its face, Lori stabs it in the eye. She uses the gun he brought and shoots the other walker in the head. Maybe she's not as helpless as most people thought.
Meanwhile, in town, Rick has convinced Hershel to head back to the farm. Just as they are about to leave, they hear movement outside. They aren't walkers, but don't sound local. They call out looking for Dave and Tony, the two men Rick gunned down at the end of the last episode.
As the men outside are about to enter the bar, Glenn jumps in front of the door to keep it closed. The men outside say they just want their friends, but Rick and his moral code has him yell out that he killed them after Dave and Tony drew their guns. The outsiders don't take this too kindly, and open fire on the bar.
Back at the farm, the group is sitting down for dinner and they realize that Lori is missing. Carol goes over to where Daryl is set up out in the field and asks if he cows where she is. He does, saying Lori had asked him to go look for Rick and Hershel, but he's done running errands for people he doesn't owe anything to. Upon hearing this, Shane jumps in a car and speeds off. He gets to the crash site, but Lori isn't there.
Rick keeps trying to talk down the outsiders, but they keep shooting. Glenn hears movement outback, and goes to check it out. As he's walking through the supply room, he sees a shadow through the window on the door and when the knob starts to turn, he fires a shotgun blast through the window. Rick regroups with Hershel and Glenn and thinks it's a good time to get out of there. He tells Glenn to make a break for the car, and that Hershel will cover him.
As Glenn goes out the back into the alley, a bullet whizzes by his head from behind. Hershel looks over that way and puts one right in the guy's chest. Rick joins them in the alley and as he's making sure Glenn is OK, another man on the roof across the street is firing at them as well. A truck pulls up and the driver yells to the man on the roof that a lot of walkers are on their way and they need to leave.
The guy on the roof tries to jump down, but takes a bad step and slips. As he falls, his leg is impaled on a wrought iron fence. Ouch.
As walkers start to gruesomely pick apart the guy Hershel had shot, Rick decides they can't leave the guy, who turns out to just be a teenager, stuck on this fence to bleed out. Hershel says to shoot him and put him out of his misery, but Rick thinks they can save him. As Hershel attempts to amputate the leg, Rick and Glenn hold off a lot of walkers with some well placed shots. Hershel is taking too long, and just about they they're about to be overrun, Rick yanks the leg off the fence as the guy screams in pain.
As Shane is driving, he sees Lori walking on the road. He tells her a bold-faced lie about Rick being back at the farm to ensure she gets in the car. Once back at the farm, she realizes she was lied to, and that Shane said he was doing it for the baby, which he still thinks is his. In the house, Lori and Carl talk, but don't have "the talk," as Dale says that's Rick's job.
Shane asks everyone to leave so he can talk with Lori alone. He tells her that because Rick is never around to keep her safe, and that he is, they don't need Rick anymore. Lori confronts him about Otis, and how Shane sacrificed him. He doesn't really confirm of deny it. Lori then tells Shane that she had told Rick about their affair, that she was carrying on only because she thought her husband was dead (which is what Shane had told her).
The next morning, Shane, Daryl and Andrea are about to go into town to look for Rick, Hershel and Glenn when a truck comes up the driveway. Lori embraces Rick, and Maggie brushes past her father to hug Glenn, as they get out of the car. Then someone sees the fence guy in the back seat and asks who that is, and Glenn nonchalantly replies, "That's Randall."
Hershel fixes up Randall's leg (well, half of it anyway) and the entire group holds a meeting in the house. There seems to be a split vote on what to do with Randall: let him heal for a little bit or send him on his way now. Obviously, Shane is in the "let's get him out of here" camp, convinced that Randall's friends will come looking for him, and that Rick is inviting more trouble by bringing him to the barn.
Andrea catches up with Shane, reassuring him that he did the right thing with the walkers in the barn, lying to get Lori to come back, and what he was saying about Randall. "It's your presentation that's the problem," she tells him. He's too hot headed to care what Andrea is trying to tell him and that she's obviously trying to help.
Lori and Rick are in their tent, about to try and relax after the whole ordeal from the previous night. Lori brings up Shane, telling Rick that Shane's very dangerous to everyone. In a very Lady Macbeth-like move, as Lori is draped over Rick's shoulder, she tells tells her husband that Shane thinks the baby is his, that Lori is his, and that Rick can't protect the group. Rick stares off, with that similar look he had when he shot Dave and Tony, as the episode ends.
