neither have i...i read about the version with mi xue and damian lau though...i don't think sff's character existed in that version.
so i doubt she would have existed in the book.
i just wanted to see Yun Lei grieve for her diciple...considering how sff was so devoted to her.
but then again, they lost that too...at first when they were together the two girls were really close then when the guys appear they went after the guys and forgot about each other.
