The Duplicity Paradox was written down in a margin of a long-forgotten xenomathematical textbook by an unknown xenomathematician. It states, in its simplest form, that no two non-identical beings can perform the same action in the same amount of time while one consumes the other. Breaking it down into its individual parts:

“No two non-identical beings”. If two identical beings are attempting the same action, it doesn’t matter what they are doing, because they are in fact the same being, just in two places at once. (proven by Starlight Document #2)

“The same action”. Obviously, if they are performing different actions, there is no paradox. One being can consume the other while the first plays kriegball and the second plays with its pet baba tear.

“The same amount of time”. Herein lies the main difficulty with the paradox. How can one determine if it is in the same amount of time? If, as some believe, time is fully linear, then the paradox is inescapable; obviously they cannot perform the same action at the same time, and would have to in order for it to be the same action. The key, of course, is to make sure the two beings cannot perceive that time is different.

“While one consumes the other”. This is self-explanatory, and the primary reason why the Duplicity Paradox had to be overcome in order for the Cat and Mouse Problem to be solved.
