One of Casey’s tricks which is quite obvious is the way she always is doing nice things for people. I believe she does this to deflect any questions asked of her.
I have known people such as this who use this tactic as a means of control and manipulation. In Casey's case I believe definately so. She never had money of her own but used others people money to accomplish her plans. So her heart is far from the actual pupose which she does these things.
