By the end of The Walking Dead‘s short first season, which followed a perfect premiere with a disappointing lack of character development, we were finding it hard to care whether the show’s band of zombie-apocalypse survivors lived or died. In fact, we weren’t sure we’d keep following the series in its second season — especially after the first trailer did nothing to convince us that we’d be in for anything more than Rick Grimes’ heroic head-busting. Thankfully, a new teaser does in 15 seconds what that clip couldn’t accomplish in a minute: it suggests that our white-knight protagonist is in for a big change (namely, a crisis of faith in his role and mission) in Season 2. “It’s just a uniform,” says the cop, looking defeated as he removes his badge. “I don’t mean anything now.” It’s worth noting that Rick is alone in both the previews we’ve seen so far, as well as in a pair of new posters. Does this mean he’ll be separated from his wife and son — or worse? Watch the teaser after the jump and let us know what you think is in store.
