After that finale, everyone was wondering how Sophia was in the barn all along and no one knew about it. Well, this episode provides the answer. It turns out that Otis was the man responsible for wrangling zombies and locking them up in the barn. Clearly, Otis stumbled upon zombie Sophia and tossed her into the barn with the others. Before he knew anyone was looking for the girl, he shot Carl and then rushed out with Shane to get medical supplies. But Otis had no idea the man he was trusting was actually one of the craziest bastards around. Shane shot Otis in the leg and let zombies tear the guy apart while he was able to escape and, in turn, save Carl's life. The secret of Sophia's location literally died with Otis. But on a more important note, I swear this show has something against children. First kill? A child. Sophia? Turned into a zombie and shot in the face? Carl? Shot in the gut. Run for it, kids!
