Hulk notices that Brookes spending habits are out of control and if he can't find a way to curb them she may buy them in to peoverty. So to teach her about the value of money, he puts her in charge of her own money. Brooke happily agrees to this with the feeling that she is grown up enough to do this on her own but she soon discovers that perhaps her father was right about her extreme spending when her credit card bill comes.
