To be fair, this disease was featured prominently in the news. This individual took it quite literally, as evidenced by the fact that he had it etched on his forehead (or face?).

Was Bruce Wayne successful in containing the disease by developing a vaccine? How much time did it take him to do that? And what if we find out that the animal responsible was actually a pangolin and not a bat?
