This is the penultimate episode of Season 6 – and if previous seasons are any indication, this is an episode where we may well lose a beloved regular character. Maybe it’s wrong to expect the unexpected, but so far on The Walking Dead, that’s been part of the pattern. And in this episode, Carol has left the safety of Alexandria, and Daryl is determined to find her. Whatever happens, this second-half burst of episodes has been especially intense, and impressive.
