To be clear, we have nothing but respect for our readers, but we all know there are a few idiots among them. In case you're not caught up, and for some reason don't want to (like if you don't have thirty-five or so hours to dedicate to zombie television), you are in luck. We're here to do the heavy lifting and run through what you've missed so that you're primed and ready to go by Sunday's season four premiere on AMC. And in case you really meet the definition of "idiot," and not just in the casual iTunes for Dummies fashion, you should know that a video of this nature is pretty much nothing but spoilers. Consider our ass covered.
