I think we should start with the thing that initially pisses of Gianna, which is being duped out of some art she really wants. Like you said cere, she could be trying to place a bid from somewhere else, and Nicholas had offered a lot of money to Gianna's lackeys to drop her call. The auction concludes, and Gianna is left without her precious art.<br/><br/>All we need is a way for her to find out Nicholas's intentions.
