5. Rick Shoots Sophia The Walking Dead ('Pretty Much Dead Already')
Things are about to go pear-shaped down on Hershel's Farm. Glenn has revealed to the group that Hershel is keeping walkers trapped in the barn, and Rick is trying to convince Hershel to let their group stay because Lori is pregnant. Meanwhile Shane isn't helping anything by being, well... Shane he wants to arm everybody, and he's angry because Dale has hidden all the guns. Shane steals them back and hands them out, against Rick and Hershel's orders. When Hershel tricks Rick into bringing back some captured walkers, Shane snaps and breaks open the barn, forcing the group to shoot all the walkers as they stumble out. The carnage ends and everyone is traumatised, only for little walker Sophia to emerge from the barn. This is Carol's daughter, whom they've been searching for all season. Rick steps up as the leader and shoots her in the head. Cut-to-black. I watched this first half of season two back-to-back, leading up to this ending, and then the wait for the second half of the season. It was a pretty heavy way to go out, and gets my nod for fifth place.
