LATER!
Ditto, Dash and Applejack gathered the rest of the main six.
But first Applejack had to think about how exactly was she suppose to break this to Rarity, didn't think that part though.
But, unexpectedly, Dash just went out and said it, not even giving it enough thought.
Reasonably, Rarity was speechless, and just stood there wild mouthed.
In fact, things were quite for a long while.
"What is this, some kind of cruel joke!?" Rarity cried, almost angrily.
"In truth.. I didn't believe it either. But I went over there, and well. Found a bit of her costume" Applejack insisted, and even showed it, to prove she wasn't lying.
"Oh my god!" Rarity cried as she snatched it from the western pony's soft hoof, and started rubbing the torn off piece of costume against her cheek, while quietly crying.
Applejack, heartbroken for her, pulled Rarity into a long hug, softly saying "It's okay.. We're get her"
"I hope so" Rarity tearfully said, while hugging her back, and cried into AppleJack's shoulder, witch the orange pony allowed to continue for as long as Rarity needs.
"I suppose we should get straight to it than" Twilight insisted.
Almost instantly, everyone agreed, accept Rarity who was still silently crying into Applejack, as the western pony patted Rarity's soft back.
"Yeah! Let's go get the meanie beanies!" Pinkie cried anxiously.
"What even are these things?" Ditto asked.
"Diamond dogs?" Rarity asked, finally releasing from Applejacks hug, and wiping her the tear marks from her eye, while sniffing.
"Yeah. I've been around a long long time, saw everything from Luna becoming Nightmare moon, to Queen of the changelings having a nice side. But I STILL never heard of such things" Ditto replied.
"You saw Luna become Nightmare moon?" Pinkie asked, forgetting that bit, from when Celestia told about his sad backstory.
Ditto could only node.
"Jeez, how old ARE you?" Pinkie asked in serprise.
"I keep forgetting" Ditto admitted.
"Uh, anyway. All we know about these things, is they're lead by the one who calls himself Rover, they live underground, hunt for gems, never bath, and THEY HAVE MY GOD DAMN SISTER!" Rarity cried, freaking out at the last part.
"Okay, okay, chill, we're get your sister" Ditto claimed, though only saying it to calm her down.
"I'm sure she's fine. She's tough for her age" Appejack insisted, again rubbing Rarity's back.
Rarity agreed to this, but it still didn't help.
"Besides, what's worst they will do, make her carry a huge wagon of gems" Dash insisted.
"So.. Heavy" Sweetie Belle groaned, having to carry a huge wagon of all the gems they found.
"Enough, with the whining" Rover groaned.
"But I'm hungrrrry" Sweetie Belle said annoyingly.
"Fair enough. But all we have is bread" Rover insisted.
"Bread is fine" Sweetie Belle, too hungry to care, as Rover gave it to her.
"I don't think there's anywhere left to find gems" Spot insisted.
"Then. It's time we moved onto bigger, better, things" Rover announced.
"... Like meth?" Fido asked.
"No, not like meth" Rover said in annoyance.
"Want some?" Fido asked.
"No I don't wa- Why do have meth!?" Rover cried.
Fido never gave a response.
