It's only 30 seconds long, but AMC has dubbed this video the "official" Walking Dead season 5 trailer. While it may be short, it's also almost unbearably tense, making it look like Rick and the survivors have been on a goddamn picnic compared to what they're about to go through. And then it gets worse.

We've heard that the first few minutes of the season 5 premiere are, in a word, "shocking." So when Tyreese's sister Sasha says, "Three of us are gone." ...man, it does not bode well. Would Walking Dead really have the balls to kill three characters in a season premiere? I can't imagine it, but I can't totally rule it out, either — which is a large part of the reason why The Walking Dead has gotten so much better since Scott Gimple took over as showrunner. I truly feel like pretty much any characters (other than Rick and Carl) could die at any time.

So who's "gone"? What does Sasha mean by "gone"? I guess we'll find out when season 5 debuts on October 12th.
