She's gonna steal Horo from Lawrence.
Did someone see Horo looking with attention to her?
And, like someone in the post, i'd never ever guess it's actually a girl. I'd think pretty much it's a desert man or smth. Curious about the her true ID.
(And 'slave trader' seems like a very good guess to me. And also, i didn't had a clue that slavery still existed in Spice and Wolf world. Do i need some history class?)
