Much like the final episodes of 'Breaking Bad,' AMC continues to keep a tight lid on 'The Walking Dead' season 4, even with the new promos. The latest to arrive with Sunday's 'Breaking Bad' episode, "Rabid Dog," offers a tantalizing tidbit, as a frightened voice begs for help! Who from Rick's group might be in trouble this season, or is there a new mystery afoot?

Clocking in around a scant quarter-minute, the brief new spot for 'The Walking Dead' season 4 features at least one item we've not yet heard before, that of an apparently female voice begging an unknown figure for help. Might this be one of the new Woodbury influx cornered during the apparent "breach?" Might the foreign-sounding voice be begging an outsider for assistance? The game is afoot, 'Walking Dead' fans!

While we await the latest details from ‘The Walking Dead’ season 4, the next run of the AMC horror-drama will introduce ‘The Wire’ star Lawrence Gilliard, Jr. as comic character Bob Stookey, and upgrade actors Chad Coleman, Sonequa Martin-Green and Emily Kinney to series regulars. The series is confirmed to have begun casting three new roles exceptionally familiar to comic fans, while David Morrissey will also return in season 4 as a series regular, though beyond this season his involvement seems unlikely.

Check out the latest spot for 'The Walking Dead' season 4 above, and give us your predictions on the October 13 premiere in the comments!
