The moment Sweetie Belle opened her bedroom door, she knew who to blame. She wasn't sure what she was looking at or how it had gotten there, but there was only one possible culprit.

"RARITY!"

"Honestly, Sweetie," came the response from behind her, "I'm across the hall, not across the country."

Sweetie stepped aside to offer a clear view of her violated sanctum. "What did you do to my room?"

Rarity furrowed her brow, looking back and forth between room and sister. "Cleaned it?"

"Not that, that!" Sweetie jabbed a finger at a gaudy pile of blue gemstones that would've fit in better in a dragon's lair. Three diamond-shaped ones vaguely formed Rarity's icon in the center.

Rarity arched an eyebrow. "These are bold words from a girl who's invaded my personal space more times than I can count."

"Yeah, but I never took up half the room with whatever that is."

That got a pout. "What, don't you like it?"

Sweetie rolled her eyes. "I told you, I don't know what it is. All I know is that it's taking up space where Button's Yule gift should be and you're obviously the one who made it. And shoved his in my closet." The portrait wasn't exactly the finest craftsmanship, but it was the thought that counted. And that it portrayed Sweetie as a bounty hunter who shot aliens and didn't afraid of anything.

"What gave me away?" Rarity fluttered her lashes. "The elegant lines? The refined aesthetics?"

"The forty pounds of costume jewelry."

"Costume? Puh-lease. I'll have you know I trekked to Equestria to get you the finest baby blue sapphires my equine counterpart and I could procure."

Sweetie frowned at that. "Wait, didn't Sunset say we're not supposed to bring in gems from Equestria?"

"Not to sell, no," Rarity said with a dismissive wave, "but I should think that making a gift for my dear, beloved, and woefully unappreciative sister is a worthy cause."

Sweetie shrugged and looked back at the lump. "So what is it?"

"Can't you tell?"

"How many times have I already asked that question?"

Rarity gave a long-suffering sigh, which might have had an impact on Sweetie if she hadn't heard it at least once a week for most of her life. "Honestly, some days I wonder how I even came about my artistic vision. Well, Rainbow Dash was telling us all about Scootaloo's little shrine to her, and well..."

She trailed off as Sweetie turned to face her, the expression on the younger girl's face enough to stop her cold. "Really?"

"I just thought—"

"Rarity, Scootaloo doesn't have to live with Rainbow Dash. She's definitely never had to share a bathroom with her. I am not worshiping you."

Rarity spouted off a number of shocked noises. "Well! Just for that I ought to cast you out or smite you or something."

A golden flash from the shrine made both turn to it. Sunset Shimmer brushed some dust off her shoulder and waved. "Hey. Sorry I didn't return your text earlier, degenerate matter forming in a nebula, long story." Sunset scowled. "Now, what was that about smuggling gems out of Equestria?"

Rarity paled as much as she could. "Er, well..."

Sunset blinked, glanced behind her, and quirked an eyebrow at Sweetie Belle. "Is this a shrine?"

"Rarity did it!"

"Sweetie!"

"You did."

"And that's how I ended up here for the weekend," Rarity concluded.

Princess Twilight Sparkle gave a slow nod, her wings fidgeting. Which, to be fair, made her one of the best composed ponies in the establishment. "I... see. I didn't know the Ponyville Hay Burger even had an employee uniform."

"It doesn't, beyond a hat," said Rarity, fighting back a twitch as she once more became aware of the synthetic fabric pressing against her shoulders. "Sunset improvised."

"That does explain all the sapphires."

Rarity nodded, making various parts of the rayon monstrosity clatter against one another. "Quite. So, that was two number nines, a number nine large..."
