Well, I don't really know too much about vampires, or the type of vampire you would find in the Fleur du Sang. But, from reading over the profile, the idea that seemed the most interesting to me, would be to have a plot where Valentine finds herself in the company of a female that is the exact opposite of Val in terms of how she sees men. The woman would have to be someone that Valentine has at least a certain respect for, in one way or another, because I highly doubt she would give anything she would say any merit otherwise.
The appeal to this, would be that it has nothing to do with her vampirism (and thus would deter from falling into the 'same old routine'), but everything to do with what seems to be the main driving factor of her life. At first I thought perhaps a man could come along that would make her question her bias, but it seemed a bit unlikely she would ever really be able to entertain a man's ideas outside of feigning interest in her game to "get them".
Not sure if that's what you're looking for. Technically the woman who could at least plant the seed that Valentine's bias is a bit extreme doesn't have to be a vampire herself, so it does open up the opportunity to more people who may be able to play it out with you. *shrugs*
