One thing I find strange or, laughable, is everytime a zombie goes through a window, they break the glass out first. Of course its a natural reaction to the living not to get cut but, I doubt a zed could/would distinguish the broken glass as being harmful.
And as far as last night goes-
Shane and Otis deffinately should have planned an escape strategy before going in the trailer. That alleyway they ran through, coupled with 5 or 10 gallons of gas on the ground and 1 more flare would have made for a nice toasty getaway. A 3rd person waiting in the truck would have been helpful too. But, I'm just a dumb human sitting on the sidelines lol.
SyFy gonna take a stab at ZPOC.
