Etty laughs and touches her again; it refreezes, and she withdraws the aura, and it's gone - no slush.
"Sure. I can't channel for you, though, do you want me to hang around anyway?"
"I mean, should I go home, or take further advantage of Glass's hospitality."
"You could stay! And then you'll see what my aura is when I get it. Jane, is Corona freecasting now?"
It acts superficially similar to Kas and Petaal's, but with a difference - Kas and Petaal's aura is focused on being very inviting to people who they'd like to touch them, and then on discouraging people they wouldn't. Nona's aura is less welcoming - more of a 'why yes, you could snuggle me, if you want' than a 'come snuggle me! right now!'.
Etty could definitely snuggle her. Glass would also be allowed, if she liked.
And there's one more thing, although no one presently in the room is experiencing that aspect directly.
"I think part of it is always on. Withdraw it and I'll see if I can figure out which," Glass says.
"Nobody is going to be able to touch you if you don't want to," she concludes, squinting at the remainder of the aura. "But advertising it and enforcing any distance beyond no-touching are only when it's out."
She produces a square.
It looks like it is filled with fresh blood; when she turns it over, the liquid moves with the motion of the coin.
Nona giggles. "I love you," she says. "Jane, can you put me in the Belltower please?"
Besides Corona, three others learned it while she was gone - Jellybean, Beast, and the Joker. Sue shares the sensations around; no two Jokers do it quite the same way, and there are departures in flavour going off in all different directions from just his and Harley's original independent discoveries.
Nona isn't next. That's Alice and Queenie, within a few minutes of each other. But she manages it a little while after that, and then it clicks for Micaiah, and there's nobody left here without it.
They celebrate.
And then Nona decides she would like to celebrate with Etty some, so she freecasts home - landing in the orchard, because it's the easiest place to get to. (She's learned how; that doesn't mean she's perfect at it yet.)
