In the later episodes, I've been noticing some parallels to The Stand (Stephen King). Chiefly: the main city that survivors are going to is Boulder, Colorado, as it is in The Stand; and the gradual gathering of forces, that will probably end with a clash between the Good people and the Evil people. In The Stand, it was a clash between Las Vegas (evil), and Boulder (good). They never actually went to true war, but I won't go into the whole plot.

In We're Alive, it looks to be a clash between The Military/Tower people, and The Mallers/Colony. Anyway, here's how this relates to Ink: In The Stand, the main antagonist is a demon/otherworldy force who names himself Randall Flagg. If I was to draw another parallel, I would say that Ink is a sort Randall Flagg character.

In the beginning of the show, the news reporter said that Ink was a paranoid schizophrenic. I think that his schizophrenia was actually visions from a force that wanted him to lead a legion to eradicate all people. After the whole outbreak started, Ink's visions told him to go to the cracks that appeared in the earth, and let himself be infected with the disease directly. So, since he was the one meant to lead, his infection endowed him with the power to do so.

I also think that the different types of biters are the result of Ink using his power to warp humans/biters into new and different forms, so that they'll be more effective when he decides to go to war. And one more slightly cracked out theory: I think Ink might bargain with The Mallers, to gain the extra force to go to war against the Good people.

So... Ridiculous, or am I on to something?
