Batman sets to work, constructing an elaborate Super Molecular Dust Separator to filter the mingled dust. Robin asks him whether it might be in the world's best interests for them to alter the dust samples, so that humans can no longer harm one another. In response, Batman says that they cannot do so, reminding Robin of the fate of the Penguin's henchmen and their tainted rehydration, and can only hope for people in general to learn to live together peacefully on their own.
