We found The Walking Dead Season 4 mid-season finale to be an incredibly intense, dramatic, emotional hour, and as far as executive producer/comic book creator Robert Kirkman is concerned, that’s precisely what it was meant to be. In the behind the scenes video below, Robert says the mid-season ender was “meant to be the most explosive, craziest episode we’ve ever done.”

And indeed it was!

Showrunner Scott Gimple describes the episode as follows: “This is Rick’s destiny clashing in with The Governor’s”, and co-executive producer Denise Huth agrees. “We were always building to this place where these two people really had to collide...I don’t think he [The Governor] goes into the prison thinking ‘I’m going to blow it to bits.’ He wants the prison to be in one piece.”

Scott also notes that he wanted the tragedy of the episode to resonate on multiple levels. People were obviously and understandably sad about Hershel Greene’s (Scott Wilson) passing, but there was sadness in The Governor’s (David Morrissey) death as well. “It wasn’t merely a tragic thing as far as Hershel dying, but it was a tragic thing for The Governor to do...and yet he’s succumbing to it,” Scott says.

As we know, once The Gov. sliced Hershel’s head off, all hell broke lose, or as Andrew Lincoln (Rick Grimes) articulates, “As soon as it happens, Rick realizes that there is no option now and that he has to kill this guy. There is no way back...Both men are willing to fight to the death.”

And by the end of the hour, our beloved group is scattered in several different directions. “Our characters don’t know if their loved ones have made it,” Gale points out.

And in perhaps what is one of the most ominous statements we’ve heard from him yet, Robert Kirkman concludes the video with the following tease for the back half of Season 4. “I think a lot of these characters are going to come out of this group of episodes dramatically changed from how they’ve been.”

But don’t just take our word for it, check out the complete video for yourself below!

The Walking Dead Season 4 returns to AMC on February 9, 2014, at 9 p.m. ET.
