Something I don't understand, so we know Charlotte was filthy rich, yet Ezra was paying her? And also during season 3 A said 'Imagine what I could do with $50, 000 ' if she was supposedly rich why make that comment. Besides the one who ended up with that money was Ezra, which brings up another thing before that episode, A had gone to Montecito and left a $50 bill folded in half( the camera focused on it) Next episode Aria finds the money in Ezra's drawer all the bills are folded in half the $100 and the $50's too so, to me Ezra could very well be AD or its helper.
