The six-episode first season of AMC's zombie drama ended with Rick Grimes (Andrew Lincoln) and his band of survivors leaving the Center for Disease Control and looking for signs of life as they navigated a world filled with "walkers" like these.
Jon Bernthal plays Rick's former right-hand man and best friend Shane Walsh, who thinking Rick was dead, got very close to his wife, Lori (Sarah Wayne Callies) and became a father figure of sorts to their son, Carl. Season 2 finds the group of survivors battling the obstacles, including freeways littered with abandoned cars -- and their undead owners.
Andrea (Laurie Holden) heads into the second season still pissed at Dale (Jeffrey DeMunn) for saving her life at the CDC. After watching her sister Amy die from a walker's repeated attacks, she wanted to remain at the CDC as the clock ticked down to its ultimate self destruction. Dale ultimately forces her hand and she begrudgingly leaves to save his life.
Lori and Carol (Melissa McBride) hide under an abandoned car as the group hits a dead end on a highway littered with cars. As Dale and company work to clear the road of to get through, a band of walkers threatens everyone's safety. Lori and Carol share a bond as they're both traveling with their respective children, Carl and Sophia.
Norman Reedus' Daryl, still angry over Rick leaving his brother, Merle, for dead, makes the best out of a bad situation and opts to rummage through the abandoned cars looking for supplies during the Season 2 premiere.
Special effects makeup designer Greg Nicotero has been upped to co-executive producer on Season 2 of the zombie drama, signing a first-look deal to develop other projects for AMC in early September. As part of the pact, he'll also direct an episode during the series' sophomore season.
The group has found creative ways to combat herds of the undead -- often smearing themselves with blood and sometimes just running. Executive producer Robert Kirkman, who created the comics on which the series is based, has said that The Walking Dead is an extension of the horror genre and is not interested in telling the origins of just how the zombie epidemic began.
Dale and Glenn (Steven Yeun) are two of the group's most reliable guys. Dale effectively is the father figure of the group, while Glenn continues to be the guy who's most willing to take risks. Glenn will find romance this season with Hershel's daughter Maggie when Rick and company seek refuge on his farm.
Robert "IronE" Singleton plays T-Dog, who played a large role in leaving Daryl's brother Merle handcuffed on a roof in Atlanta, may have better plans for survival than sticking with Rick's group. In the Season 2 opener, he slices his hand as he attempts to hide from the incoming zombie herd.
The 13-episode second season of The Walking Dead will be split in two parts, with the first half premiering Sunday, Oct. 16 at 9 p.m. with a special 90-minute installment. Six hourlong episodes will follow before the series goes on hiatus. The back-half of the season will bow Feb. 12 at 9 p.m.
Daryl, Rick, Lori and Carol search the woods for a missing member of their impromptu family in the Season 2 premiere. Executive producer Gale Anne Hurd says the AMC series provides new opportunities to introduce characters, like Daryl who aren't featured in the long-running Image Comics series.
