I have noticed that everyone has said that the ending of The Walking Dead Season 2 explains the zombie outbreak, but for me it kind of did and kind of didn't. I noticed that Shane and the guy in captivity turned after being killed. Though also it was an act of aggression that turned Shane, and was he slowly turning the whole show leading up? Did I get it right the first time and it was death that created the beast? Have I gotten it wrong on all accounts and I am just blind? Will someone explain my madness? Thanks in advance.
