Her character is completely unnecessary. In season 3, she inserted herself in every situation she was in, kept on minding everyone else's business, slept with a rapist, kept sleeping with Bryce when he said it wasn't a good idea at all, slept with Bryce while harboring feelings for clay, and she lies her butt off to protect herself!!
And there's something I really don't get. How did she have an intimate friendship with Bryce, but still covered up his murder?
