When an episode comes along as pivotal as Season 4's mid-season finale — Episode 8, "Too Far Gone" — we're extra grateful for Talking Dead, the talk show that accompanies our favorite zombie apocalypse drama. Host Chris Hardwick talked with guests as major as the episode: Lauren Cohan (Maggie Greene), weeping and holding hands with Scott Wilson (the dearly-departed Hershel Greene), plus series creator Robert Kirkman.

Scott Knew he Was Gone Starting With Episode 5. Scott got the talk about Hershel Greene dying while filming Season 4, Episode 5: "Internment." "You're making a big mistake," reflected the actor on the talk, laughing. "But it's yours to make and I'm not gonna fight you on it."

Baby Judith May Not Be Dead. Every week, Talking Dead has a reel of every death in the series. Judith Grimes was not on it. That's all we know, guys.

Robert Kirkman Re-Wrote The Governor's Death for the Catharsis. The Lilly that killed The Governor (David Morrissey) in the comics was a recently-introduced character, Robert says, and he wrote the death to be almost anti-climactic in that case. For the series, though, he wanted the death to be "satisfying." It definitely was; pretty much the top 3 folks that really wanted a piece of The Gov got to at least participate. David Morrissey said that only one person can kill the Governor, but it ended up being a total group effort for Rick Grimes, Michonne, and Lilly Chambler.

David did recognize in an interview aired by Talking Dead that he had to go when he did. Fans, he said, "know that he died having done the worst thing he could possibly do [...] he had to go."

Andrew Lincoln found the death in the episode pretty satisfying, too. "So many things happened in that episode are […] traumatic," he said. "When you find out that someone's leaving that [was your friend], you want to honor their death."

The Governor's Tank Has Seen Action IRL. The tank that Daryl Dixon (Norman Reedus) blew up this week, a 1971 M60, was used in Vietnam! It was on loan from a collector, who says it "would make hamburger meat out of zombies."

Carl's Stunt Double Is a Grown Woman. She's 31, and her name is Ashley.

David Morrissey Didn't Wear Pads While Beating Up Andrew Lincoln. "David was really game because I had to hit him a couple of times, and he didn't want pads, he didn't want anything," reflected Andrew in an interview. "He was a very brave gentleman."

Rick Would've Died Without Michonne. As if there were any doubt! Robert confirmed, though, that Rick was just a couple of seconds away from dying before Michonne shoved her katana through The Governor's vital organs.
