Vivienne was the duke's mistress long before become a mage court.
She was still an apprentice when they first met.
Pay attention to what she says and stop fawning over her.
You are making some big assumptions here. Give me solid evidence that it happened the way you are saying and not the other way around.
The fact is, you might be right. In fact, I'll say you are probably right. She might have met Bastien as an apprentice and immediately become his mistress. And then he might have arranged for her to move out of the Circle and into his estate. And then she might have leveraged that relationship to get the position of Court Mage, and then been granted rooms in the Winter Palace as well. That is a plausible way that it could have happened.
But, she might also have met him as a young apprentice at the Ball and fallen in love with him. Then she might have run across him over the years where she pulled an Anne Boleyn style romance with him as she moved up politically, eventually securing the position of Court Mage and becoming his mistress. That is a less likely, but also plausible way that it could have happened.
Why I am most likely done with this thread now is because, just like any other argument on BSN, most people are refusing for even a second to entertain the other point of view. This is a great example of it. There is literally no evidence to support your claim over the scenario that I mentioned, but you state it as if it is adamant fact and then add a snarky, passive aggressive line at the end for anyone who disagrees with you.
Most of the Vivienne supporters in this thread like her, yet acknowledge her less redeeming qualities. Most of the Vivienne haters in this thread are refusing to accept any positive given towards her. It's why I appreciate that Xhil and Addai, while still not liking her, are willing to at least acknowledge good points made by her supporters. <sigh> I should know better than to expect a debate on a 'controversial' character like Vivienne to not just turn into two sides yelling at each other and not listening to what the other side has to say. I have a strong feeling that if we polled the people in the thread the vast majority of the Vivienne haters are also strong Pro-Mage Rebellion players and are letting that tint their interpretation of an incredibly well written and complex character. Good old BSN.
