And then it happened: The moment that redefined The Walking Dead, if only because it proved that the show is defiantly willing to go there when it has to. One last walker emerged from the barn. It was a small walker. A child. A girl. Motherf---ing Sophia. Just like that, the entire main plotline of this half-season was proven to be pointless. Just like that, all of the various hopeful conversations about Sophia -- Daryl's angelic soliloquies about pretty flowers, Carl's constant assertions that Sophia will love life on the farm, Rick's insistence that Sophia was alive -- suddenly looked bleakly hilarious in hindsight. They were never going to find Sophia. Daryl almost died for nothing. The moment she left the highway back in the season premiere, she signed her death warrant. Shane was right all along.
