Besides supporting the feeling a lot of us had that she has some sort of in with the BA but was still a light-sider, I didn't think it was to big a surprise. She got a list including most of the BA, I think the percentage she acquired might have been a bit too high even for her vaunted skill, but it's not like the ratio really mattered, apparently 80 of 200 BA escaped, 40%, and techincally the number discovered wasn't too important, since they used the rod to check everyone anyway, so she could have gotten aquarter of them instead of 90% or so and had the same effect, possibly barring if Sheriam, ALviaran, or that other sitter hadn't been included.
