For a moment, unsure of how to approach what is very clearly a delicate moment that no one has seen in the Ringmaster (for as long as he can remember, at least), Joker lingers just inside the balcony.

(Out of sight of the ballroom, for the most part. He doesn't want to draw anymore undo attention to himself after already going at it with Sans.)

Finally, however, he'll click his shoe against the floor as a heads up before approaching her. Please don't kill him, RM.
