After a couple months without it, AMC’s “The Walking Dead” returns this Sunday, February 10. But if you’re like us, you’re so impatient that you want to know what happens in the next episode right now. Well, lucky for you, a script of the first few scenes from the mid-season opener has leaked online. No need to worry about spoilers, though. If you don’t catch on to why that is shortly into reading it, you’re probably just about as dumb as a walker.
