Season 3 of AMC's hit drama series "The Walking Dead" is really heating up, and the cast talked to OTRC.com at PaleyFest on March 1 to dish on some of the gruesome details.

Several cast members, including Andrew Lincoln and Laurie Holden, shared some juicy tidbits about the third season of the zombie thriller, and how their character's have evolved. Another thing the actors shared: they don't know what's going to happen until ... well, until the week that it happens.

Lincoln, whose character is the leader of the group, explains why he thinks it's beneficial that the actors are left in the dark from week to week.

"It's like the saying, 'It's one of the greatest thrills,'" Lincoln explained to OTRC.com. "I mean, we don't even know what's going to happen - so, yeah, I mean it's tense. When Sarah Wayne Callies (Lori Grimes) died, it was incredibly shocking - you know, it is incredibly painful when we lose such great and beloved characters, but, what also happens is the show kind of reinvents itself - so the show is like a moving target."

The show, which debuted in 2010, follows Rick Grimes (Lincoln) and a group of survivors whom he leads in a world overrun by zombies. The group has endured a number of trying times, including the loss of friends, wives, and for some, limbs. The current season has seen the group endure a number of obstacles, eventually finding a place of refuge in a prison that they made their temporary home. While a new addition, baby Judith Grimes, has kept some of the group occupied, a nearby threat in the town of Woodbury looms, and the group is preparing for battle.

"The Walking Dead" airs on Sunday nights at 8/9 CT on AMC.

The PaleyFest Panel -- 'The Walking Dead' (SPOILERS!)

1. Carl has been stepping it up ... and he's not done yet.

"You got to see Carl step up, he's no longer Carl," Gale Anne Hurd, one of the show's executive producers explained at the panel. "There was a threat, he stepped up, and there's a little less of a threat right now."

Carl is the main character Rick Grimes' son, who has recently shown that despite being young, he's a force to be reckoned with.

"Carl really is one of my favorite aspects of the comic and the show," Kirkman, one of the show's executive producers explained. "I mean, watching this kid grow and change and evolve the way that he has, and go from this kid who is almost a burden to this kid that's you know, a child soldier, is just a really cool exploration of the world of 'The Walking Dead' - seeing how people grow and change over time. Where we're going to go with this kid, is some pretty exciting places - this season really is just the beginning of his journey and there's a lot of cool stuff ahead for him."

2. Well, maybe The Governor isn't COMPLETELY bad ... according to the show's producer.

"You know, I think the governor, there is something in him that's good," David Alpert, one of the show's executive producers explained. "I think there is a part of him that wants to sort of take care of people and be that father figure - but, I feel like the situation, you know, with the zombie apocalypse, has unleashed this thing in him. And, the darkness has allowed him to grow and prosper."

3. Laurie Holden talks her character, Andrea, and her complex feelings for the governor.

"[He's] a bad man. She did [have feelings for him] - until she went back to the prison, and found out everything that she did," Holden explained during the PaleyFest panel. "I mean, let's be clear here, when she goes back and she sleeps with him that's not because she's having a weak female moment and thinks he's handsome - she really thought that she could follow through with Carol's plan. I think sleeping with him disgusted her, and I think she woke up and ... you know it's one thing to kill someone self-defense and it's another to stand over someone as they're sleeping and kill them in cold blood. ... Andrea's never killed a human being before.

4. Rick (FINALLY) realizes he may be unfit to be leader.

"Something happens in this episode this week - this weekend - that really holds a mirror up to Rick, and he realizes that ... I think it's a turning point and he realizes that he has to come back from the wilderness," Lincoln explained at the panel.
