A minute later, the rest of the girls were lounging on Twilights furniture (actually, Rainbow Dash was the only one really lounging, the rest of the girls were just sitting). Bill was staring at them, and if he had a mouth, he would probably be grinning mischievously.
"So," Rainbow Dash said. "Why does Celestia want you in her library again?" Twilight sighed.
"To study," she said. Bill snickered.
"And to free me!" he exclaimed to no one in particular. Twilight glanced at him.
"What are you looking at?" Pinkie asked. Twilight looked at her.
"I'm not looking at anything!" she said nervously. "Who said I was looking at anything?" Pinkie giggled.
"Your always looking at something!" Pinkie said. Twilight face hoofed as Pinkie continued to giggle.
"She's funny," Bill commented. "It be a shame....if something happened to her." Twilight stared at him, horrified. Rainbow Dash raised her eyebrow.
Discord must be doing something to her, she thought.
"Umm, Twilight?" Fluttershy asked.
"Yes?" Twilight asked, looking back at Fluttershy.
"Um, has Discord done something to you?" she asked. Twilight shook her head.
"No, just....thinking...about some of the books I read today. About being a princess," she said. Pinkie giggled again.
"Were they really about being a princess?" Pinkie said, barely containing another laughing fit. "Or was it something else? Like porn?" Then Pinkie started laughing again. Rarity gasped and blushed, along side Fluttershy. Rainbow Dash started laughing and Applejack facehoofed. Twilight blushed and snickered a little.
"Porn, huh?" Bill said. "That's a good idea!" He then disappeared in a flash.
"So, what do you have planned for tonight?" Pinkie asked, finally calming down from her laughing fit. Twilight shrugged.
"I was planing on studying a bit more and then going to sleep," Twilight said. "Why? What are you planning?" Pinkie grinned.
"Oh, I'm not planning anything," she said. "I've already got it planned! Sleepover!" As she said sleepover she threw up her front legs and confetti exploded everywhere.
"Pinkie!" Twilight said. "What if the other girls have things planned?" She glanced at the other girls, but all she got were confirmations that they had nothing planned for that night. Pinkie giggled.
"Don't worry about bags!" she said. "They were in the party explosion!"
"Well then," Twilight sighed. "We might as well do this."
"Yeah!" Pinkie exclaimed. "Now I can meet this new person!" Twilight froze.
"Pinkie, you're imagining things again," Rainbow Dash said. Twilight glanced at Bill. He motioned for her to follow him, so she did, into the kitchen.
"So, it's almost nighttime," Bill said. "At night, it's harder for me to keep up the hidden thing as well." Twilight nodded.
"Ok, so stay in here," she said. Bill made a tsk sound.
"Yeah, that's not going to be possible," he said. "You see, when I meet new people-or in this case, ponies-I need to play pranks and stuff." Twilight stared at him, and sighed.
"As long as it's nothing to serious or suspicious," she said.
"Sure it won't," Bill cackled.
