The apocalypse will happen in both worlds, if Adam has his way.
New futures. New pasts. The same troubles.
The two 2019s are each headed for apocalypse, one way or another.
Jonas returns to 2020 to save everyone. Things go terribly wrong. Or, do they?
In 2052, Jonas seeks answers. In 2019, Winden deals with the missing six. And in 1921, Noah meets himself.
