In separate scenes alternating back and forth, we have Rick bandaging his hand, and Carol talking to Lizzie through the glass at the quarantine. Carol tells Lizzie that she's going on a run with Rick, and that Lizzie needs to be strong. Lizzie tells Carol that nobody has died "yet". She talks about how becoming a walker is part of the change of life. And how it's the same as being small and growing bigger. Rick through the conversation, preps for the trip, filling a van's gas tank, and looking around cell bock A. Carol stresses that Lizzie needs to put her life and the life of her sister over everything else. Lizzie insists that she isn't weak, but has her shirt over her knife. Carol corrects it so that she can get to it faster. Lizzie slips and calls Carol "mom", Carol corrects her quickly, even during Lizzie's apology. Lizzie tells Carol that she's not afraid to kill, she's just afraid. Carol tells her that she can't be, and that she just needs to keep going, keep fighting, and one day she'll be different. ..Read the full recap
Carol: Maggie wanted to come, you know?
Rick: Someone had to stay back, watch over things.
Carol: Someone you trust, you mean? They would have drowned in their own blood. They were suffering, I made it quick. We needed the bodies gone, we needed to stop it from spreading. They were the only ones who were sick, they were a threat. I was trying to save lives. I had to try, somebody had to.
Michonne: You should have let him go.
Tyreese: What the hell do you know about it, huh? You the damn expert?
Michonne: No, I just don't want to see you die. Is that what you're trying to do? Do you even know what you're trying to do? I know you're pissed, and you have every reason to be, but anger makes you stupid. Stupid gets you killed.
Tyreese: Aren't you still angry about the Governor? What he did?
Michonne: If he was here right now, I'd cut him in two. 'Cause that's how it needs to be, but I'm not angry. I was.
Tyreese: Then why are you still out looking for him?
Michonne: I don't know.
Daryl: Those douche bags in the vines, they took themselves out. Holding hands, kumbaya style.
Bob: They wanted to go out together, same as they lived, does that make them douche bags?
Daryl: It does if they could've gotten out.
Bob: Everybody makes it, 'till they don't. People nowadays are like dominoes. What they did, maybe it's about not having to watch them fall.
Rick: Did you think it was right...letting those kids come back with us?
Carol: I think it was the humane thing to do.
Rick: But did you think it was right?
Carol: Look at us, digging through drawers, hoping that a couple of cough drops and some disinfectant might be the difference between dying and living a couple of more hours. If they're strong enough to help us survive this, then yeah, I think you made the right call.
Rick: And if they're not?
Carol: Let's hope they are.
Carol: Rick, I killed two people and you haven't said a word about it.
Rick: What do you want me to say.
Carol: It's not about what you say, it's about facing reality. It always comes for us, and over and over again we face it so that we can live.
Rick: So that we can live.
Carol: That's right. That's what it always comes down to. You can be a farmer, Rick, you can't just be a farmer. You were a good leader, better than I probably gave you credit for.
Rick: I never murdered two of our own.
Carol: Just one.
Rick: He was going to kill me.
Carol: So were they, they were going to kill all of us.
Rick: You don't know that.
Rick: They might have lived. Karen and David, they might have lived, and now they're dead. That wasn't your decision to make. When Tyreese finds out, he'll kill you. He damn near killed me over nothing.
Carol: I can handle Tyreese.
Rick: When the others find out they won't want you there. And if they don't make it back, if everybody dies of this thing and it's just the two of us, with Judith and Carol. My children...I won't have you there.
Carol: Rick, it's me. No one else has to know. I thought you were done making decisions for everyone.
Rick: I'm making this decision for me.
