Kellhus spent much time and effort developing the entire school from nothing. He had to personally train every witch until there were enough to carry on the task. He built that school to be entirely independant from every other one, and wouldn't have risk their influence in having them teach his students. Kellhus must have been deeply involved with Serwa's upbringing, both in the school and in the various dunyain trainings that now make her appear sane.

Do you have a location for this, because I don't remember it.
I think she IS more human than most of the other kids. Esmi thinks back to how even when Serwa was a baby, she showed signs of humanity and the ability to love.
