"Miss, we treat people with conditions that leave them looking like that sometimes. Do you have any credentials. Or references."

Sigh. "Do you have, like, a papercut or something I can fix." 

(This nurse is pretty convinced Lucy is wasting his time.) "What would your treatment look like, exactly?"

Well, Lucy is pretty sure he's wasting hers. "It would look like me glowing at the injury and then the injury being gone." 

"As it happens, I don't have any injuries at the moment. If you find someone who's injured and willing to accept your treatment, or one of the patients who comes in here accepts it, and it is effective, please do come back to demonstrate."

"Ugh, I don't have time for this."

She starts glowing. 

Her radiance ramps up, going from nothing to a faint glow to a beacon to a penetrating luminosity that pierces through the very walls and ceilings and floors, imperfectly opaque as they are. It would be blinding if it didn't heal corneal damage faster than it could cause it. 

She ramps down again after a couple of seconds have passed, then turns around and walks out, leaving behind her a hospital filled with zero injured and zero corpses. 

"Miss- Miss what did you just do-!"

The nurse runs after her. 

"You need to stay here! You just unleashed something without any kind of safety checks or verification or anything, that's not right!"

"I know what it does. I've been doing this for years. You can check up on it all you want, but I have more people to heal." 

The hospital has a crowded evening street's attention already, being the source of some sort of Incident. The shouting isn't helping.

The nurse runs over to a police officer on the opposite side of the street and starts ranting and gesticulating towards Lucy.

She continues calmly walking away. 

The policeman jogs to catch up to her. "Miss. What's your name and are you responsible for that light just now?"

"Lucy Whitman, and yes." 

"Is it true you said it was a medical treatment? And that you didn't receive any kind of permission or consent to administer it? Or demonstrate that it does what you claim?" The policeman glances at the nurse, who has followed, scowling.

"I offered to demonstrate, he blew me off." 

"I said you could find someone to demonstrate on-"

"Sir, please leave this to me."

"She barged into a hospital and 'treated' all our patients with some kind of light - you know how light can be - without allowing for any due diligence!"

"Sir. Miss Whitman, would you mind explaining your side of things?"

"What do you know about the Neath." 

"Oh, this is-"

"Nurse, be quiet. I am the officer here, not you. Just general background information. The Bazaar, the Tomb Colonies, the Fifth City, the Elder Continent, the Zee, the Avid Horizon. General details. How is that relevant?"

"I am the daughter of the Mountain of Light, and the light that I give off is the same light that makes death less than permanent in the Neath." 

"That's a very extraordinary claim. Miss. Given the, uh, treacherous nature of most light in the High Wilderness, do you think you can see why it might make people skeptical and alarmed?"

...She stops.

"Not...exactly? I mean, I, uh, now that you mention it I can see it, but there was some kind of accident involving Hours and the Correspondence and from my perspective a few days ago I was in London when it was still back in the Neath and the best way to go crazy involved Seeking the Name. I, uh, have been trying to acclimate, but, okay, that was my bad and I apologize." 

"Thank you. Would you come back to the hospital with us so we can sort things out and keep anyone from getting too worried?"

"Yeah, okay." 

They go back to the hospital, the main lobby of which is filling with confused staff and patients. The officer asks Lucy to wait, calls in some backup, then goes to confer with several doctors, who glance at her warily and curiously and hopefully. That nurse sulks off to a side-room somewhere.

A Reckless Chronicler walks a bit closer than the other recovered patients, mutters, "Hmm, Correspondence?" and attempts to read the sigils on her dress.

"Oh, uh, yes, I'm...naturally fluent. Which means I can handle it safely." 

"I would sell my soul for that talent, you know. Fascinating stuff, the power that the words of fire can give. If we could codify it, it would be a whole new branch of science, bridging poetry and engineering!"
