That grin turns into a smile, mostly because even if he's guessed who she is (finally) he's not interested in revealing that to anyone else around. But it does, of course, come complete with Claude withdrawing one of the butterflies tucked away in his sleeve to pin to the lapel of her vest.

"I think it was the confirmation of what you told me about why you'd voted for me, really," he says teasingly as the music begins to slow to wind this particular dance down despite heading that way for a while. "Don't worry, your secret's safe with me."

Something he means even if he's not going to give away the rest of the reveal, not when there's a chance to still play along for the last few seconds as the song comes to an end and Claude steps back for another curtsy. The proper kind he's witnessed from many a noble lady at the end of these dances where he was the one standing where Abby is now, and all the better to keep up the princely illusion for anyone who might be watching. "I was right earlier also, by the way. This was a pleasure."
