"That ignoring it doesn't mean it doesn't exist, and if Celestia's not going to do anything about it, she should at least let other ponies have the opportunity to try?" she says, a bit sadly. "Yeah. I knew someone like that once."

Well, that's informative. Here she is not saying anything. Can she Bluff a minor god? Yes she can.

"Yeah, something like that."

A drop of liquid falls from the sky and lands on Abrogail's nose.

On closer examination, it's chocolate milk.

"What the fuck."

"What—?" She notices the milk rain. "Shit."

"Follow me," she says, and starts to run towards the statue section of the gardens.

Through the trees Abrogail catches a brief glimpse of the alicorn she saw before, heading away from the gardens in a different direction—blue with an orange mane and a cutie mark of a setting sun.

"Who is that?" she asks Luna.

"Who is who?" she asks. "I didn't see anyone."

"Blue male alicorn, lighter shade of blue than you."

"There aren't any male alicorns. I mean, it's not impossible in principle, but there aren't any. Might be a foreign dignitary whose natural form looks sufficiently alien that he'd rather be a pony for the night."

They reach the statue garden. Discord is, predictably, gone.

We have a situation, she says to her sister over their permanent telepathic bond, then teleports herself and Abrogail to Celestia's private audience room.

Celestia isn't there, but she teleports in accompanied by Twilight and her friends a moment later.

"I noticed," she replies.

—followed by Valiant Victory flying in through an open window a moment after that.

Um.

Yeah 'um' is right, she's just going to ignore that situation until the emergency is dealt with, though.

"Well, well, well," says a deep voice that seems to be coming from nowhere in particular. (On closer inspection, an image of Discord in a stained-glass window appears to be speaking.) "Looks like the gang's all here. Let's skip the exposition; they've seen it already."

"Uh, no we haven't."

"I didn't mean you, Applejack," says Discord with a chuckle. "I meant the people who really matter. And if you haven't seen it yet, you should. I'm quite entertaining, after all."

"Who are you even talking to?"

"Don't worry about it!"

"Anyway," he says, yawning dramatically, "having to listen to this explanation twice is sooo boooring. The Elements of Harmony have chosen new bearers, blah blah blah. They're not in the vault and you'll have to find them, blah blah. Meet me at the entrance to the labyrinth."

"Are we actually supposed to do what he says?" Twilight asks the Princess.

"Unfortunately, yes," says Celestia. "Sometimes with Discord you have to let him play his little games."

"Oh, and you too, Abrogail," says Discord. His image then vanishes from the stained glass window as though that's a perfectly normal way for stained glass to work.
