Helena Ravenclaw
For the beginning of the evening, Helena stuck by the Founders, especially her mother. It was the polite and expected thing to do. She managed to break away though and spend the rest of the evening socializing. She didn't drink anything alcoholic, only water. She probably sat by Arianna or Evan and whoever they chose to sit by. She would, however, like to meet new people. She wore a really pretty dress that she was sure her mother would approve of, as well as be an attempt to wear something more modern.
One of the suits of armor jumped out at her as well, causing her to drop a plate of food at one point.
[OOC: feel free to start a thread with her or reply how your kids interacted with her.]
