Hershel Greene: if it wasnt for him, Rick never would have made it.
“I didn’t want to believe you. You told me there was no cure, that these people were dead, not sick. I chose not to believe it. But when Shane shot Lou in the chest and she just kept coming, that’s when I knew what an ass I’ve been. That Annette had been dead long ago and I was feeding a rotten corpse! That’s when I knew there was no hope. And when that little girl came out of the barn, the look on your face - I knew you knew it too. Right? There is no hope. And you know it, like I do. Don’t you? There is no hope for any of us. “

Morgan Jones: if it wasnt for him, Rick also never would have made it.
“-But you know about the dead people, right?
-Yeah, I saw a lot of that - out on the loading dock, piled in trucks.
-No, not the ones they put down. The ones they didn’t - the walkers, like the one I shot today. C’ause he’d have ripped into you, tried to eat you, taken some flesh at least. Well, I guess if this is the first you’re hearing it, I know how it must sound… But listen, one thing I do know - don’t you get bit. I saw your bandage and that’s what we were afraid of. Bites kill you. The fever burns you out. But then after a while… you come back.”
And forget about Rick, Shane, Daryl, Andrea, Glenn.. they are not underrated.
