I think using any form of logic, we can derive that whilst Ink made LA and the surrounding area pretty awful, there would have been similar archetypal characters across the globe. It seems almost of though Ink was more like an obsessive rather than a genius that saw it coming. There are plenty of these around (all the end is nigh types) along with all of the actual geniuses or people with slight genetic defects that would make them almost immune from the virus (28 days later). I would almost bet that each continent would have its own special types either from environment influence or from the regions own 'Ink'. Lets face it, as soon as anything happens, people love to experiment with it. And we all secretly have the maniacal laugh hidden away.
