Robert Kirkman knows exactly how The Walking Dead outbreak occurred, but you’ll never see it in the pages of the comic.
During a panel at the New York Comic-Con Thursday, the series creator explained that both readers — and the characters themselves — won’t find out what was behind the deadly (undeadly?) zombie apocalypse:
I’ll never reveal what the source of the outbreak is in the comic. I’m never going to do that. I know what caused it. Any effort to have them become aware of the source would bring the comic into the realm of science fiction and I don’t think that would be necessary.
