[She didn't know either.]

Naoryuu went missing, but I just thought he was playing around or in his Pokéball already. When I realized he was gone, I searched high and low for him! I couldn't trust to ask anyone, because even if they weren't against me, word could get out and any kidnapper could just cover their tracks more.

And then he came back evolved as a Vaporeon! I don't know why they'd just kidnap Pokémon to evolve them.
