    The cast of AMC's zombie drama 'The Walking Dead' premiered season four on Wednesday night in Universal City in California. British actor Andrew Lincoln said the new season could be best summed up in a question: ""Can we ever come back? Can we ever come back for the things that we've done and seen, the brutality of this world?".
