Now that 'The Walking Dead' season 4 has officially set its Comic-Con 2013 plans, all manner of new details have begun to emerge from the fourth season of AMC's acclaimed horror-drama. The recently revealed premiere title gave an insight into a potential time jump for the October debut, but what do the latest-announced supporting characters tell us about 'The Walking Dead' season 4?

According to TVLine, at least three new characters have been added into the mix, likely from the influx of Woodbury survivors in season 3 finale "Welcome to the Tombs." Among the additions to the prison include Laura, a single mother and ex-nurse who isn’t quite as strong as she first appears, Melody, a ‘just one of the guys’ kinda gal in her 20s, and Don, who "sounds like Hershel, if Hershel were crankier and two-legged."

To date, 'The Walking Dead' season 4's largest addition has been that of army medic Bob Stookey ('The Wire' star Lawrence Gilliard Jr.), who himself had originally been misdirected as a character not of the books. The same could be true of the above three, as "Don" (Danny Vinson)'s curmudgeonly demeanor sounds much more like the comic counterpart of Bob Stookey, while Melody and Laura could represent any number of characters, let alone original creations.

While we wait for the first season 4 trailer from Comic-Con 2013, the next run of ‘The Walking Dead’ will upgrade actors Chad Coleman, Sonequa Martin-Green and Emily Kinney to series regulars, while AMC earlier confirmed that David Morrissey’s villainous Governor would also return in season 4 as a series regular.

We'll be on hand in San Diego to get the scoop on any new characters from 'The Walking Dead' season 4, but what do you think? Could the next year prove even more explosive than the last? Watch the latest preview below, and give us your thoughts in the comments!
