"Yes," she says to Hatter. "I see what you meant, now."

To Audrey, she says, "There is a way we could perhaps find out for certain. Sophia's reflection was not de-aged when she was, if I remember right, and would still look like the queen we knew. Have you looked in a mirror since you arrived here?"

"No, I haven't. I wasn't exactly in a fit state. Do you have one handy?"

"Oh, I'm sure I can dig one out from somewhere..." Hatter says. 

He leads Audrey through to a sitting room, which is full of hats and hatboxes stacked on every surface. One corner has a curtain draped over a section of wall, and he pulls the curtain back to reveal a full-length mirror with a simple wooden frame.

Stepping back, he gestures for her to stand in front of it. Everless flaps her way onto his shoulder to get a better view.

She steps forwards, and looks into the mirror. 

She has no reflection.

Hatter blinks. 

"Well. That's something."

Everless lets out a surprised caw, then cocks her head to one side.

"May I perch on your shoulder?" she asks Audrey after a few seconds of thought. 

"Sounds like an interesting idea. Go ahead!"

Hatter helpfully transfers her from his own shoulder to Audrey's by letting her perch on his wrist.

Everless' reflection, unlike Audrey's, shows up perfectly well in the mirror, as does Hatter's arm where it comes into view. She steps from one perch to the other, and her reflection hesitantly puts out a foot to follow suit.

It goes through thin air; the reflected bird overbalances and falls off Hatter's arm, flapping and squawking in perfect silence as if she's on the other side of a thick window. 

Audrey stifles a giggle.

The reflected raven rights herself, preens her feathers back to smoothness, and hops through the mirror. 

"Her reflection appears to be elsewhere," she reports. 

"... of course Everless' reflection is also a person. I should have been paying more attention."

The two ravens begin discussing theories, talking over each other in a barely-understandable cacophony.

"Reflections in Wonderland are alive," Hatter explains, "although I doubt most of them would meet your definition of 'person'. They can move and speak independently of whoever is casting them, and some - like mine and Everless' - can move through mirrors. In general, if a person is a mirrorwalker, their reflection is as well."

"Are they like the people who cast them?"

"The theory - and mind that I'm not an expert, but Everless is busy - is that your reflection is something like...the way you see yourself, or the person you would like to be."

He gestures at his own reflected image in the mirror, which appears to be a mundane Earth-type exact reflection. "Mine doesn't always look like this; right now it's a stand-in because my real reflection is elsewhere. But it's not very different."

Audrey considers that for a long moment. 

"... I see. That has Implications. If my reflection can do things, what is it doing right now...?" 

She sighs. "Add that to the list of Plot Points: 'find my missing reflection for insights into who I Truly Am.' As if I haven't done enough introspection already."

"Yes, that does sound like it would be useful," the Hatter agrees.

"It may not be that easy, though. Your reflection could be anywhere in Wonderland or its mirrors."

Discussion apparently concluded, one of the ravens - probably the reflection, if that's even a meaningful distinction - takes off and disappears through the mirror.

"This would be a particularly useful moment for the Cheshire Cat to appear," muses the remaining Everless, "which undoubtedly means that he will decline to do so."

"I mean, it wouldn't be a Quest if it was easy. The real, ha, quest-ion is what to start with, my missing reflection or the lion with the missing heart."

She rubs the back of her lips with one finger. "... we seem to have a rash of disappearances, don't we? I'm not sure what that means, but... something to note." 

"There is an additional issue with restoring Lionel's heart," Everless says.

"Lionel himself is the Queen's loyal servant, having spent the last decade being raised and indoctrinated by Marcella personally. Does that fit into your patterns?"

"... Marcella stole his heart. It's within tolerances." 

She rubs her chin and frowns. 

"Still not a good sign. An ace up..." 

Audrey sighs and rubs the bridge of her nose. "Is his title literally the Ace. Is that what he is."

Hatter gives up on trying to keep a straight face and starts laughing, a little hysterically.

He ends up sitting on the floor with his back against the side of an armchair, face buried in his hands.

"How...?"

"If I had a deck of cards I could explain! But alas, I don't. Let me guess, there's a Ten of Hearts down to a Two of Hearts as well?"

"...Yes," Everless confirms. "So named for the number of Wonderlanders' hearts they have been granted for their personal use. The higher the number, the higher in Marcella's favour. It is also, to a first approximation, a guide to their relative magical and political power."

Audrey nods seriously. "This is important, so listen carefully. So long as Marcella has her Ace, her King, her Jack, and her Ten, the court of Diamonds will only ever be able to equal her in strength... save perhaps if there's a wild card, but even then we'd need five of a kind and Marcella has all the Hearts. We can't beat her at her own game: she quite literally holds all the cards."
