In between the warning from Morgan we get some fast-paced action, with walker-stabbings, gunfire, Carol witnessing someone being killed (or put out of their misery), and the group led by Rick running through the woods. The death that Carol witnesses seems as though it should be fairly significant, given it goes out of its way to show it happening but keep it shrouded in some mystery, while once again the threat isn't clear. They have to keep moving, Rick tells them, but are they on the run from walkers or humans?
