you had found yourself on the Zeppelin, you'd chosen hiro over all the other men you saw at the golden place, in the golden place he could speak english, but yet there was a language barrier, he only spoke german and japanese, he didnt notice you because you were face down, and not saying anything, he turned and jumped back a bit

"あなたは誰ですか?"

he'd see your confusion and switch to german

"Deutsch?"
