In a new Entertainment Weekly interview with Robert Kirkman, he talks new characters in Season 4, the aftermath of Hershel’s death, and the thought behind the decision to splinter the group. Here’s an excerpt from the interview:

EW: Okay, where’s Baby Judith?
KIRKMAN: All I know is that there’s a bloody car seat so things aren’t looking too good.

EW: How about Lilly and Tara. Will we see them or anyone from the Governor’s storyline again, or is that chapter complete?
KIRKMAN: There are some people in that mix that we didn’t see die that could theoretically pop up at some point in the future.

EW: We know we’re going to see new characters in the back eight, a few big ones from the comics — Abraham and Rosita and Eugene. What can you tell us about them and how similar or different they will be to the original comic iterations?
KIRKMAN: These characters are going to be extremely similar to who they were in the comics and I’m really excited about that. The visuals and costuming for them has been absolutely amazing. These people really do look like they were torn out of the comic page, it’s pretty startling. But I will say people excited for the introduction of these characters won’t have to wait very long. I don’t want to reveal exactly when they’ll be introduced, but it won’t be too terribly late in the season so get your hopes up. They really are going to add a very interesting and very compelling dynamic to the show. I think they’re going to bring in elements to the show that we’ve never really explored before and I think that’s exciting and something that’s going to change the game to a certain extent. I’m always very excited at how much this show evolves over time and changes season to season and these three characters are agent that very much changes the story and very much changes the direction of the show to a certain extent.

EW: How do you decide whether to make people look like they do in comic, or have them look completely different, like Bob Stookey?
KIRKMAN: It’s never done that way. All we ever do is we have the role, we know what we want to do with the character and then we cast them. If we can cast an actor that looks like the characters in the comics, great. But that’s not something we ever try to do. It’s just not possible to find the best actor for the role and somehow match them with the drawing that was done almost a decade ago. We always look for the best actor for the role, period. It would be an unrealistic endeavor to try to match the comic visually at all times.

EW: What about this new character named Gareth? What can you tell me about him?
KIRKMAN: Nothing.

EW: Okay, well, is there a new character named Gareth? [laughs]
