After realizing that they had been guarding an empty bathroom for the past four hours, Suncatcher angrily stormed off. She'd have thrown her helmet at the ground for extra emphasis, but she'd already done that earlier and no longer had a helmet to throw.
"Suncatcher," Posterior warned, raising his voice slightly, "your shift hasn't ended yet. I will write you up if I have to.
"You go do that," she called back at him as she marched away.
"Are we still meeting for dinner?" he asked.
"Yeah." Suncatcher turned the corner and disappeared from sight.
"Out of all places, Celestia?" Luna blinked a few times to be sure that she wasn't just seeing things.
"Yes."
"You cannot be serious."
"But... why?" Luna had to duck as a pineapple the size of a house whizzed over her head.
"Because mother is going to be furious when she realizes that we left the bathroom, and a party might just distract her. She did request one, after all," Celestia explained.
"We're having the party in here?" Luna asked, perplexed.
"Of course not!" Celestia exclaimed. "We're just here to ask Discord to plan the party for us."
"Oh. Right." Celestia and Luna stood there for a minuted. "So... are we going to do that, or...?"
Celestia snapped back to reality. "Oh, yes." She walked forward and knocked on Discord's front door.
"I'm coming!" A voice yelled from inside. A few loud crashes were heard, a jet of fire blasted through a window, and then Discord finally opened the door. "Yes?" he asked, swatting away a plant that was creeping over his shoulder.
"We came to inquire about our mother's party," Celestia informed him. "Will you do her the honor of planning it?"
"Nope." With that, Discord marched outside and kicked the two alicorns in the direction of the bottomless pit.
"Okay, so let's begin!" Suncatcher announced. Posterior cringed a little at her happiness - should he be worried? "I was originally gonna do this my myself, but then my sister stopped by for a visit and she agreed to help."
"Your... sister?" Posterior struggled to understand this. How could anyone live with a sibling this annoying?
"Yeah, she should be here soon. Maybe in about- oh, never mind. She's here." Suncatcher waved at somepony being Posterior.
Posterior turned around to see... Suncatcher? "Wait... what?" he asked.
"We're twins," Suncatcher explained, "identical twins. Sunchaser, meet Posterior. Posterior, meet Sunchaser."
Sunchaser stifled a laugh at Posterior's name but said nothing of it. "Nice to meet you."
"Likewise," Posterior said. Similar names and identical appearance. Just great. They both had the same yellow-and-orange mane and tail and mane and the same white body. And since Suncatcher wasn't wearing her armor, he couldn't even tell them apart by that. "If you don't mind my asking, how am I to tell you to apart?"
"Our cutie marks are different, and so are our eyes," Sunchaser told him. Posterior gave the two a closer look and realized that she was correct. Suncatcher's eyes were violet, whereas Sunchaser's were of a yellow-green hue. Sunchaser's cutie mark was of a lightening bolt, whereas Suncatcher's was of a tornado. Weather ponies? Odd, seeing as Suncatcher was a guard.
"Oh, I see. Suncha- I mean, Suncatcher-"
"Yet another pony who can't keep our names straight," Sunchaser groaned. "Alrighty then. You can call me Chase and my sister Sunny. Make sense?" Posterior nodded. "Good. So here's what we're gonna do: Sunny is going to be the date that you try to impress, and I'll be off to the side, coaching you. I'm going to be the date that you try to make lose interest in you, and Sunny will be off to the side, coaching you. Sounds good?"
"Uh... why do I need to practice impressing a date?" This was not what Posterior had signed up for.
"Because if we're going to teach you one skill, we have to teach you the other," Sunny declared happily. "C'mon, aren't you excited about this?"
"No," Posterior grumbled as Sunny sat him down at one of the cafeteria's tables. "No, seriously, I'm not ready. I need to shower first!" He stood up quickly and fled the two mares.
"Wimp," Sunchaser laughed. Suddenly, mustard rained from the sky.
"All guards report to the throne room!" a voice shouted. Suncatcher shot her sister an apologetic look and ran off.
