"The others are suspicious. I've been trying not to jump to conclusions about you, but if you have some reason to be afraid of Sora, I guess it's silly to cling to the hope that this is just a trivial visit." She said it all calmly, with a serious but not unkind look on her face.
"I will say that Sora's a good kid. He won't hurt you unless you threaten him or his friends." She gave a wry smirk and added, "he accepted me readily enough, back then." It was her indirect way of finding out for certain what he was. His response to those few words would very likely confirm or deny the current theory.
