As whit says, the clues aren't terribly specific, and some simply aren't true.
The first seems to imply that she is not the boss, and that she is trying to prove to another unicorn that she is.
The second is okay, but is very vague and applies to many characters.
The issue with the third is that it's simply false. Members of the plague aren't all in the Basin
The fourth clue is entirely too objective; As a rule, never use an opinion of your own as a clue.
