Tyreese: You're a cop. You find out who did this and you bring them to me, you understand? You bring them to me.
Daryl: We'll find out who brought them out--
Tyreese: Do I need to say it again?
Rick: No, no. I know what you're feeling. I've been there, you saw me there. It's dangerous.
Tyreese: Karen didn't deserve this. David didn't deserve it. Nobody does.
Hershel: We just went through something terrible. Everything we've been working so hard to keep out? It found its way in.
Rick: No, it was always there.
Glenn: We're going to be okay, right? I mean, Karen and David, they were already sick so if we were going to get it we would have had it by now.
Hershel: It doesn't happen on a timeline. It's different with everyone.
Glenn: We could be okay.
Hershel: Yeah, we could be. Everything could be okay.
Daryl: Oh, there you are. Took me damn near forever to find you. What are you doing?
Tyreese: Somebody needs to stand watch.
Daryl: Man, I want to find them too. Put a bullet into them for what they did. These people are cut off. There ain't no way people are getting in and out without a whole bunch of people seeing them.
Tyreese: Shasha's in there. I ain't going nowhere.
Daryl: Standing guard ain't going to do no good unless we come back with the meds.
Tyreese: I'm going on a run with Daryl, but I was wondering...I know there's a lot of people in trouble. Sick. It's just, I know how you are, you care.
Carol: Thank you.
Tyreese: I was wondering if you could look in on Sasha for me. It would make me feel better knowing you were looking in on her. If you can't...
Carol: No, no I'd be happy to.
Tyreese: Thank you.
Carol: What happened to Karen, I'm so sorry.
Glenn: This sucks. After everything, I'm just going to get taken out by a glorified cold.
Hershel: Don't say things like that. Don't even think things like that.
Glenn: All I can do is stop saying them.
Hershel: No, you can do more. We got this far somehow, you can believe somehow. We all have jobs here, and that one is yours.
Rick: You know, you do a lot for us. For the kids. You sacrifice a lot. Is there anything you wouldn't do for the people here?
Rick: Carol, did you kill Karen and David?
