But as Twilight entered the back room of her library, she discovered once again that there was no sight of her assistant Spike nor any sort of memo. She was going to write this decision off as a lost when something caught her eye. Something very mysterious. The rear door was slightly ajar. And from where Twilight was standing, she could see a trap door, hidden in the shadows of Carousel Boutique. In all her time here in Ponyville, Twilight had never even seen it once.
How peculiar. Twilight walked out the Golden Oak Library and got a closer look at the trap door.
