The Walking Dead: What Could This Year’s Cliffhanger Be?

In a recent interview, The Walking Dead creator Robert Kirkman teased a cliffhanger that would make the wait between Season Four’s finale next week and Season Five’s premiere in October unbearable.What could that be? It seems unlikely the survivors will still be on the road; more likely is that they’ll have reached Terminus already (or at least whoever is still alive and moving in that direction will have) by the time anything remotely cliffhanger-y happens.Whatever it is, it seems this is a bit of a twist on the promise that there would be a happy (or happier) ending to the season than we’d seen in the past.  Can both be true?
