Stardust does not have an applicable complication so it falls on her whether her lust for another would cause her to act dismissively, dominant, or perhaps she begins imagining what could happen when they resolve their encounter.  So effectively no mechanical effect just yet unless Stardust wants something to happen.<br/><br/>If she does succumb to the transformation then her new complication may force her to take certain actions based on her lust.  She'll have an ego roll to resist but if it's strong or total there's a good chance she'll give in to whatever he wants to do with her.
