But how does she know rand is around the corner about to Balefire the place back 100 years? Why does she even suspect he would do this, and use her compulsion as proof of life? she would have to suspect him capable of this and have a plan in place before hand. And she would be fairly confident her hideout was hidden to rand, she compulsed folks so much they died before they could give info, except that one boy had enough to whisper two words.
She must be dead, or be super crafty and smart, more crafty then one could reasonably expect.
