In Hindsight...

After the creature left, Celestia's posture, grace, attitude, as well as her mental and physical facade flew out the window, not dissimilar to the actions of the strange creature. A guard calling her snapped her out of her reverie.

"Princess, shall I send an order to capture the thing?" His voice suggested that his professionalism had flown out the same window hers did.

After a moment or twenty of thought, her mouth created the most appropriate response known to any sentient kind.

"Bwah...? No. Just... Ugh..."

She was actually conflicted on whether the creature's intentions were pure, but he did incapacitate her guards... By dancing. It hurt nothing but their pride, so she saw no reasoning from that point of view. BUT, he did blow not just one, but TWO holes in her magnificent castle. Which was completely fine, as she wanted to redecorate anyway. Still... What was that thing?
