She does, and can tell Wynflaed as soon as she gets back from the banquet. Lilige will be with Aedre...unless Aedre gave her the slip and went to the stables, but I think Nienna had decided against it? Either way, she'll probably be in her Lady's chamber. It would be natural for Wynflaed to ask if she'd seen who it was, and Lilige can and will tell her.
