"You're the best?"

It doesn't sound fully sceptical. Maybe a little bit, because.. well, it's a very bold claim to make, but it's not exactly like Ange has any proof to the contrary. For all she knows, maybe Toph really is the best at this where she comes from. The blindness already gives her a certain advantage in being able to approach this power from a very different angle than most people would think to, too.

"How many people can do this sort of thing where you come from?"

Are you the best out of only ten people, Toph? Or are we talking The best out of a million people? There's a difference!
