I still can't help but thinking about what Kalani says about Ground Zero. CJ's convoys encountered strange creatures there. He then lists the specials ones. Now it seems that Ink may be manufacturing the gas; possibly for his experiments.

It's almost like Ink's special creations are made with gas as opposed to bites. This adds legs to him foreseeing the outbreak, possibly building a tolerance to the gas over time.
