After that Sinnoh arc, Dawn and Chloe were discussing about dreams and destiny, they did mentioned about the decision on evolution for their Pokémon. Piplup made a decision not to evolve during the Diamond and Pearl series because of his experience on protecting Dawn when those two met. As for Chloe’s Eevee, well like Lillie and Chloe, there destinies are uncertain. Her Eevee somehow can’t evolve or could never decide which one she wants to evolve to. That’s why she has the move Copycat to tryout different attack moves from other Pokémon. After what we’ve seen so far, maybe I like Chloe’s Eevee to be a unique Eevee carrying different moves from every Pokémon she has meet. It could be like Mew who carries traits of different Pokémon. It might be impossible, but it’s worth seeing it happen if she doesn’t want to evolve.
