The "walkers" in this episode definitely seemed different, starting with the two cops that Rick and Shane took out at the gate. Was it me, or did they look a little more gray than pale?
I was also pondering the pile of incinerated bodies that Rick discovered at the Municipal Center, along with the pile that the group burned on the farm after Shane busted open the barn. Does that somehow tie into the explosian at the CDC? Perhaps incineration allows the virus to become airborne?
