Ask Mara, daughter of Nightmare Moon
Avenger raises an eyebrow. "How c'n somepony related t' YEW not be cool?"

Mara shrugs.

“I don’t know how it happened, but somehow it did. Moonlight and Lunar are so not cool.”

A what now?

“One of those ponies that come from other places to talk to mom about stuff. Other than mom ‘n’ dad ‘n’ Aunt Luna, the only ponies I’ve seen with wings and horns are those ‘bassdr guys!”

Avenger frowns slightly, tapping her hoof against the chin. "Now, now. Tuh Queen of everythin' may be good at everythin', but ah really don' think she has tuh same grasp on this subject as AH do. She has some.. Outdated views, see?" The supermare nods. "Cool ponies take drugs!"

“They do?” Mara thinks about it, for a while. “But… Moonlight isn’t cool at all!”

Avenger shrugs. "It's cos she didn' take 'em with friends! See, there's some intricate drug takin' rules. Rule number one: Iff'n yuh REFUSE drugs from ya friends, yuh're a square. Rule number two: Iff'n yuh take drugs by yaself, yuh're a square 'n a LONER. Rule number three: Iff'n yuh TELL tuh authorities when others take drugs, yuh're a RAT. 'N rats git 'sterminated." The avenger smiles. "Makes sense, right?"

Mara nods, even though it still doesn’t make much sense to her.

“I think so. Momma said she’s gonna explain it to me ‘n’ Moonlight ‘n’ Lunar, later, so I’ll probably figure it out even better then. Momma’s really good at explaining things.”

Hello there.

Mara looks over the strange alicorn pony.

“Hello. Are you one of mom’s guests? An… um… ‘bassdr?”

"A drug?" Avenger blinks in surprise. "Well, ah guess it's a thing yuh take t' make yaself feel good!"

Mara ponders that for a moment. “But… there are bad drugs? Like the ones Moonlight got in trouble for?”

The Avenger nods. "She took drugs off of somepony who weren' me. It's very naughty."

Mara looks up at the Avenger, somewhat confused.

“What’s a drug?”

"Eeyup!" Avenger beams, positively glowing happy. "But enough about me, yuh're what's importan'!"

Mara bounces over to Aunt ‘Vengerlady, and whispers in her ear.

“I head Moonlight got in trooouuuble!” She giggles.

"Hey." A pink supermare trots out of the shadows. "How're things, Princess Mara?"

Mara gasps in surprise as the Avenger trots out.

“Aunt ‘Vengerlady! You’re a grown up again!”

You're a very pretty mare, you know that?
