Here's my problem with the earthquake releases ancient bacteria problem. The outbreak happened simultaneously throughout a number of major cities. The only way that could have happened is if there were a number of earthquakes in a number of different places. And if there was something like that taking place, then we would have heard about the earthquake that came before the outbreak. Also if the boom michael heard was the earthquake that began the outbreak, then they would have mentioned crazy shaking. An earthquake would need to be an 8 or higher to start cracking the ground open the way it was described, and I guarantee you that everyone would have felt a level 8 earthquake. Just my two cents. Also angel still isn't back yet.
