She spoke Russian to that ballet women and that guy that is treating her. Is she like Bourne, where she speaks all different kind of languages. Arnold can't... I think.

She can mimic what she hears and more than likely she has detailed files on many languages!

I'd love to see her speak spanish to the quiet spanish girl, and then she finally speaks to her because of that. that'd be the ultimate. hehe

Maybe she can't speak. Mute.

I really don't think so. i think she's voluntarily just not speaking. like a vow of silence. i dunno.

She didn't speak anything in the whole season.

Well then it was easy for her to memorize her lines!
