Forum:Mara Jade and Darth Vader

I have a question. In the article on Mara Jade, it says, or it seemed to say, that she hated Darth Vader, and hoped he would betray Sidious so she could kill Vader and become the new Sith apprentice. However, in Star Wars: Allegiance, it sounded more like she respected Vader, and that she was trying to get along with him. What's the real story?
