Last week’s episode ended with a new non-zombie character approaching the survivors and asking to meet their leader. In the past, this type of interaction hasn’t worked out too well – on The Walking Dead, the walkers have turned out to be a lot less deadly than the remaining humans. But this new guy, played by Ross Marquand, could be a good guy after all. If, that is, he’s playing Aaron, a character from the graphic novels who made his first appearance about now in that narrative (which the TV show follows sometimes, but not always).
