Well, I don't see what's wrong with a pokémon pursuing their dream... [ Momo smiles. Her voice is still filled with warmth. ] I like seeing the bright side of things, you know? If there's never a silver lining to look at or admire, then you're just hopeless and never moving forward and that's bad.

I mean, I don't see what sort of downsides pokémon speaking human language can have. Aside from if they learned really really embarrassing words or phrases, but, that would probably only come from repetition, wouldn't it?
