I think that Nibiru is going to grab ahold of comet Ison and change its course....causing stray fragments to land in N. Korea.

One of the pieces will strike Kim Jong Un in the head while he's searching for another unicorn grave. The people of N. Korea will interpret this as their god being struck down and a sign of the 'final war' with the South.

A mis-fired nuke from N. Korea will go straight over Japan and into the Ocean...triggering a fault line...the resulting earthquake crumbles Fukushima...

Then...along the Oregon coast....a boy who has had his dna altered by eating too much GMO monsanto cornflakes will befriend a radioactive dolphin.

The combination of his altered dna and radiation exposure will severely weaken his immune system...allowing a tainted flu shot to turn him into patient zero...wherein everyone infected have unbearable cravings to eat bath salts.
