“Yes! Yes, I will joi- where did everybody go?”
Pip and Luna looked up from the parchment on the desk. “They went home.” said Pip, simply. “Dinner and Bedtime and all that. So you'll really join us?”
“Sure, sure. What are you working on?” Icy asked as she trotted over to the desk.
Princess Luna grinned impishly - on a muzzle not made for “impish”, but that pulled it off quite well, all things considered. “Oh, just a little something for the end of the month.”
The end of the mon- Nightmare Night?

“Mayhap. Maaaayhap.” Luna smiled.
Icy sighed. “My life's not going to get any less interesting, is it?”
Luna smiled with one side of her mouth.
“Thou hast no idea!”
