It would be way more fun. That isn't to say that despite any rules Jim or Viatorus put in place, Felix and Runa won't find a way to make their own fun anyway. Best test this out somewhere where at least Viatorus' magic won't raise too many eyebrows.

"You'll convince him yet, don't worry," Runa assures Jim with a wink.

As for the question of dancing... Well that stumps an awkward Viatorus. His wife only lets him flounder for a few seconds before jumping in with, "You won't be able to stop me. As for Viatorus..." She glances at the guilty looking scholar before grinning at Felix again. "We'll see what we can do."

"We mustn't keep you from your guests." Letting go of Viatorus, Runa hugs both of them in turn. "I am so happy for you! Enjoy tonight! And the rest of your lives!"
