The Elements of Harmony sat in Twilight's library, each performing their own tasks to entertain themselves. Suddenly, the door burst open and King Sombra stepped inside.
"Muhahaha! I have returned to exact my revenge upon you for killing me!" He yelled. The others looked at him for a moment before returning to their activities. Sombra was confused. "Are you not afraid? I am here to destroy you, yet you do not flinch!"
"We heard it before, bub." Rainbow Dash said from behind her Daring Do book. "Take a number and wait at the back of the line."
"But, wait. What?"
"We're available for revenge between the hours of ten o'clock and four o'clock, with an hour lunch at noon." Twilight deadpanned. Shuffling around some papers on her desk. "If you like, we can schedule an appointment, but we have a waiting list several months long. The line you so rudely cut in front of on your way in is the line for walk-in cases. Many of them have been here for hours waiting, and we have to serve those who came first."
"So take a number and wait at the back of the line." Rarity cut in, idly flipping through a newspaper. Sombra looked around and located a red box near the door. With a groan he took a strip of paper from the stand and moaned when he saw the number. He stepped back outside the door and walked to the back of the line, containing plenty of ponies, several changelings and their queen, a Griffon, a Minotaur, and a cloud of dark blue mist. He stood behind the mist and sighed.
"Sombra?" It said to him. "Sombra! It's me, Nightmare Moon! I havn't seen you in ages."
"Nightmare?" How've you been?"
"Oh, the usual. Feeding on people's rage, planning to bring about eternal night, you know." The mist flowed a bit, indicating it was looking at Sombra's paper. "They got to you too, huh?"
Sombra groaned. Pinkie Pie walked outside the library and called down the line. "Now serving number 273!" Sombra glanced again at his paper.
2112. He would be here a while.
