Chris Hardwick: Why did Hershel have a smile on his face?

Scott Wilson: I think it’s really a culmination of everything that happened from the first episode that he was in, where he was having conversations with Rick and subsequent conversations that he’s had throughout his run on the show with Rick and other people, where he was trying to counsel a humanity or a forgiveness or an ability to communicate with other people and try to keep a line of communication open with other people. And he heard Rick doing that, he heard Rick attempting to do that. And I think he thought at that time, “It’s going to be all right.” That thing that he tried to impart was, in fact, imparted to Rick and to other people as well.
