She is acting no different to Gemma and Daniella, she snipes and makes comments and will happily start an argument with them, but she then plays the bullying card for sympathy, it works for her because of her age, doesn't work for Daniella.
She made a comment to Dan the other night at the party about the way Gemma treated her will be great for her public perception, I can't remember the situation but it revealed she is clearly thinking about how the public are perceiving her and what she needs to do to help improve her popularity.
