"Did you look in Corentyn?"

what

Twilight is deeply confused about many things, including in what world any of that could possibly be a flattering portrayal of Abrogail, but she's distracted from that for a moment by an ✨idea✨.

"Story time paused," she says. "I want to see if we can use Pinkie Pie as a tuning fork for your home plane, since she's apparently been there before."

"Of course I haven't been there, silly! Nopony who isn't a Princess has ever left Equestria and returned!"

"Then how do you know what Corentyn is?—it's a city in Cheliax," she adds for Twilight's benefit.

"Because someone who has been there is also me, and everyone who's me knows everything that anyone who's me knows!"

There is, at this point, a knock on the door.

Yeah it seems like doing science to Pinkie was probably not going to turn out any better than last time.

"Come in," she says.

Fluttershy enters, carrying a sickly-looking, featherless bird on her head.

"She's sick and I don't know how to fix her," she says.

"Hi Fluttershy—is that the Princess's bird?! You need to return her immediately!"

"Yes," she says in an even smaller voice than usual. "She's sick. I just thought I could help her, but—nothing is working..."

"Can I see the bird?" she asks. She thinks she recognizes it, from the heraldry of the Padishah Empire; perhaps Celestia borrowed yet another piece of Sarenrite symbolism despite supposedly being a completely different entity.

Fluttershy sets it down in front of Abrogail.

"Idiots," she mutters to herself. Disintegrate.

"It's a phoenix," she explains. "It's supposed to burst into flames and then regenerate every so often. Probably it would have done it of its own accord soon enough. I just gave it a little push."

Sure enough, the ashes begin to float into the air, gathering into the shape of a bird, which in a flash of light transforms into a majestic red-and-orange bird with its wings spread wide. It flies over to Fluttershy and perches on her head.

"Thank you," says Fluttershy happily.

"Alright," says Twilight. "We need to get this back to the Princess before her guards notice." She and Fluttershy head out.

Abrogail follows them rather than be alone with Pinkie Pie.

"Oh, there you are, Philomena." The bird lifts off of Fluttershy's head and flies over to the Princess, hovering nearby.

"I'm sorry, Princess," says Fluttershy. "I only took her because she looked sick and I wanted to make her better."

"it's okay. But next time, you should ask before trying to help like that. I would have told you that rebirth is a natural part of her life cycle."

"Although, really, she should have done it months ago. She was getting kind of annoying about it, if you ask me."

"Yes, Princess," says Fluttershy. "It was Abrogail who actually regenerated her, though."

"Thank you," says Celestia to Abrogail, quite sincerely, then switches to Infernal. "Though I worry that you may be teaching Fluttershy that violence is the solution to all one's problems."
