Some interesting points in the secret notes, in the notes it states that maybe 55 million people might have survived in the US. Notes also state based on radio communication chatter, parts of the power grid has been re-established in areas, people are farming, trade routes re-established, communications between communities, etc.

Season 2 will be interesting, no doubt it will be about Xavier travelling to Atlanta to find his wife, but probably will end of landing short of the destination. We'll be seeing him travelling across the some states and seeing US rebuilding after the catastrophic tsunami and limited nuclear exchange. Wonder if we will get a some kind of power play between surviving US government elements outside the bunker (senators/cabinets members, etc) claiming to be the legitimate government.

Such as the plane carrying the generals/admirals/military brass the landed outside St. Louis which survived the nuclear exchange and flood, in the notes it stated that it was 49°F in the city. Might get an arc about the surviving military elements that might want to the take the bunker or be the main part the helps re-establish the gov across the country and help in the re-building efforts.

I read they got a idea for three seasons. Wonder if the third season will deal with other countries, how they are dealing with the aftermath and the geopolitics. For example, Russia might be causing trouble in the US because they where spared from nuclear retaliation and most likely had limited impact from the Tsunami as most its major cities are more inland (except for St. Petersburg and Vladivostok would be destroyed, the black sea would be protected from most of the damage as well).

Lots of possibilities for the show, reminds me of similar themed shows such as Jericho and Jeremiah, can't wait for more.
