So because of Kalani's exit from Hawaii, we can surmise without any uncertainty that the infection start simultaneously throughout the world.The time between Kalani leaving Hawaii and coming to LA and when the infection first began is not that great, and (in my opinion of course) it would be impossible for it spread and infect the entire west coast of the US in that amount of time. Sure, one or two boats or planes leave Hawaii with an infected on-board, but there is no way it started there first and came "here."

This all probably seems obvious to you guys though. Anyone think that isn't the case?
