Clarissa very much loves dancing, and if he asks her a second time- which he should, as he is her date and that entitles him, a perhaps-questionable fact of which she will inform him at some point- she will ask if he'd like to generate a bit of scandal. Dancing too close? Too fast and loose? With both she and Tairith at once? Something else? Whatever, as long as it's fun and just a little bit too interesting for this crowd.
