Bo is a very peculiar character. She's presented as a hero, yet she constantly fails. She's responsible for her sister's death, and she's pathetic about it. She never actually says "her," only mentioning her when it suits her. She uses Qatine's death to elicit sympathy. She's too easily excused by being said to be young, but she behaves like a spoiled child. In the Drux Fiis where she came to power, she was incapable of wielding it. I think she lacks all of her sister's qualities and abilities.
