'The Walking Dead' creator Robert Kirkman previews new Season 4 characters Abraham, Rosita and Eugene

In the buildup to the return of Season 4 of The Walking Dead on Sunday night, EW.com has been posting interviews daily with members of the cast. The latest edition features series (and comic) creator Robert Kirkman, who offered up the goods on what's to come in the second half of the season.

The next eight episodes will introduce three characters from the comic: Former U.S. Army sergeant Abraham Ford (Southland alum Michael Cudlitz), who travels in the comics with his feisty Hispanic love interest Rosita Espinosa (played on the show by Christian Serratos of Twilight) and former high school science teacher Dr. Eugene Porter (played by Josh McDermitt of Last Comic Standing).

Kirkman revealed to EW.com that fans of the comic need not worry about how the three characters would come off on screen:

"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."
