Quick recap
On a jammed highway, Carol's daughter, Sophia, vanishes into the woods. Carl is shot by accident and taken to Hershel Greene's farm. Shane comes back from a medical supply run without Otis, whom he sacrificed to escape. Glenn finds out Hershel's barn is full of walkers. Shane opens the barn, the group kills them all, and Sophia stumbles out as a walker. Dale is killed by a walker. Shane tries to kill Rick, and Rick kills him. Shane comes back as a walker: everyone is infected, just as Jenner told Rick. A herd overruns the farm and the group scatters. Andrea is left alone until a hooded figure saves her. Rick declares he's in charge now. In the distance, a prison comes into view.
