Most Pokémon are used to it if they're, you know... Captured. And even if we speak a different language, our feelings and thoughts come across clearly as we bond. I think it might be a one-way street, like we could understand them too without speaking once upon a time but we lost it as we started to use them instead of letting them be.

[When they started considering Pokémon "pets" and "battlers" instead of "friends" or "family".]
