Isn't that why she's always trying to kill Arthur? I know that she takes over Camelot at some point, but I thought that,a t the time, her men were trying to find and kill Arthur. After Uther dies, she has a legitimate claim as the heir to the throne, if Arthur dies. So she tries to kill Arthur, so that she is the rightful Queen. And she doesn't kill Uther immediately so she can gloat and because he is bait for Arthur.
