Interesting idea. And especially horrific would it be if those things started to run around after the haze vanished. Would they be just zombs, especially sustaining zombs, food for other zombs ... ? Something tells me we won't learn about "their" fate ...
I could imagine something like this:
William I Roberts was in the van. Then the car and he got attacked. He was wounded by a zeeh; but since he was kind of "canned in" they left him alone, because they had plenty of other and better opportunity to get food - all the lawyers, police men, court people, other convicts etc. ... So there Ink was, in his van, badly wounded. And since he was not killed, he turned into a Smart One - probably the first one to show up. And he became powerful - like what we know from regulars as well as Little Ones and all the other special zombs. He could rip the van apart like nothing (do you remember the first scene Michael described in #1-1 - with the group of zeehs ripping apart a car in order to get to the honking driver and to devour him?). So Ink was able to get free. He was not targeted by other zeehs anymore. And he did, what all them zeehs did. But in contrary to those he kept his mind. So he "attacked" other zeehs in order to play the "alpha-card" and to make other zeehs follow him as minions; and a pack of zeehs was created. And the bigger the group became, the more Ink looked for suitable locations to create his small army of zeehs - that's when the arena was established as the pit. And since he remained some of his intelligence and smartness, he also (re)activated his scientific skills. With the hospital around he had the perfect location to experiment on special zeehs. And this he did. The end of the story up until now you already know ...
Something along this line is what I think is "the", or at least "a likely" part of the Ink-backstory ...
Best wishes!
