I'm curious about the trope though. Is anyone an officer of the law or something like that profession that can provide an answer.
Why is it that when two officers are partners and one is not married and one is, the married one will die and the partner will marry their widow? Does this happen often in real life?
It was also pretty clear in the pilot that Shane wasn't stable. His conversation with Rick was odd as they eat their donuts and waited for radio traffic - on an unrelated note is there any canon as to how the virus started? In WWZ they say it came from the Three gorges Dam, but in TWD I haven't heard anything.
