John considered this, figuring her parents more the typical slave-owner type. But Joan seemed different, and truth was, yes, he owed her some gratitude. After all, he could be enslaved by someone very cruel, or someone who wanted him only as a sex slave. She was being honest about only wanting a friend, and already, he could tell being her friend wouldn't be a difficult thing. In a different situation, were they doctors working together, he could see them socializing. Hell, he could picture himself wanting to date a woman like her, in another time - she's lovely, after all.

So he nods in return. "Thank you for being honest."
