Part One:

'Scientific research continues into the Theory of Eeveelution, the hypothesis that humans may themselves share an ancestral link with Eevee from the ancient past. This would perhaps explain humanity's natural gift for adaptability as a development of the wild Eevee's adaptable nature as a result of its own mutable physiology. Tests to expose humans to the radiation of the discovered evolution stones has so far triggered several Pokévolutionary-like mutations.

The question remains: what of the Sylveons and the Umbreons? Their changes are not caused by stones; rather, they occur through a close bond of friendship with a trainer. If the theory is true, perhaps that potential exists within us all.'
