The mention of healing gets her a flood of messages. Most of the uncountable number are requests for healing a particular illness, injury, or relative, with a minority answering the question. Most of the answers are suggesting the hospital, where there is apparently already a world-class healing cape who spends most of her free time there. (Quinn's answer agrees, but he suggests not going until he's written them a suitably lawyerly letter about the name thing and making sure they know they could be liable for any names she overhears.) The mention of de-aging provokes a lot of comments on how it could affect the status quo among mortals, a lot of debate on whether it's even ethical, and fewer actionable suggestions.
Does Quinn also think she needs to have a lawyerly letter written to just heal whoever shows up to an accessible rooftop?
Even when limited to the subset of people who need healing who can get to a rooftop, any such place is likely to be crowded.
She makes sure to clarify on the forum the limits of her healing: while unlike that other healer ("808554") she can do brains she can't do minds; she mostly cannot do anything more specific than restoring some or all of a person to a healthy state - no cosmetics, no cyborg parts, no giving people wings (unless they want to be turned into a sparrow, and she hasn't yet consulted her lawyer about whether she may recreationally turn people into sparrows; Quinn, can she recreationally turn people into sparrows?); she is really, really not a doctor and cannot offer an informed opinion on how her healing will interact with any doctor things weirder than "rest" and "fluids" and "splints" and "duplicating things the mortal body already does, only more conveniently" (but wrt those things she's fine); she has never actually de-aged a mortal before, only knows the theory, and while she certainly expects not to make any big mistakes she cannot re-age anyone who she overshoots with so they'd better be okay with landing more or less anywhere in the "young adult" range; she will take more specific questions but it is more efficient to put them through the forum rather than crowding the roof where she's trying to study her patients -
And really, really, REALLY don't tell her anyone's name. Sign your form with an X or your phone number or something.
The people who show up are capable of getting to a roof on short notice and not using any complicated doctor things, which adds up to the mortals who aren't the most critically in need of healing but could benefit from it. Most would also like to be made younger while she's at it, though a few were scared off by her warning.
She spends a while looking at all of them. After about ten minutes, she starts working on people who she's studied enough who've signed their forms. She heals without further confirmations; de-aging she goes over the "you understand that as an immortal fairy I cannot nail an exact age" bit out loud.
Anyone who is there to be de-aged is already willing to tolerate that. They each assent again.
They all think so. Several offer to pay her. Eventually the miraculously healed people disperse, walking and leaping and praising Promise.
When the time window closes she flies away again.
The next time she's online, there's a message from Brockton Bay's other most sought-after healer. Apparently 808554 would like to meet her.
Actually, yes. Comes of having a sister who can fly. She suggests the roof of the Brockton Bay Central Library, the following evening.
808554 comes just after. She's a young mortal with brown hair and a white robe, barely noticeable next to the person she's getting a lift from. The flying parahuman is wearing a white and gold costume complete with a cape and crown, and it's slightly harder than expected to look away from her. She radiates an aura of oh my god, it's really whoever this is.
Thank you Yellow.
Double check. Double-check everything. Check range of effect. Note changes in thought patterns.
Proceed with established plans regardless of influence -
"I DO NOT LIKE YOUR AURA AND ONE OF US IS GOING TO LEAVE IMMEDIATELY."
Her original plan did not include hollering, but she left herself that much leeway.
Her passenger steps off. "It's just my sister, not an enemy." And to her sister, "Did you let it flare up again?"
The aura dials down. Still not gone, but much easier to ignore.
"Sorry about that. She can't actually turn it off, if I'd known you'd object I would have come some other way."
"If she can't turn it off she ought to be more careful about where she goes. I'm meeting you on a roof because if I met you on a street corner I might hear somebody's name, which wouldn't even do anything to them unless they were mid-assassination-attempt, and she goes around like that to encounter strangers?"
"She can turn it down, but usually doesn't bother when it's just us because I'm immune. She's...not usually that careless about leaving it on?"
"It wasn't just you. Were you not expecting me to show up?" Promise shakes her head. "Anyway, what did you want to talk about, and do you have a nickname that is completely unlike your real name and more pronounceable than 808554?"
I wanted to ask you about the healing you did. And- and warn you."
"You're doing it because you want to help, right? But if you start doing it you can't really ever stop, you'll always know that you could be saving someone's life right now and aren't—you've got hundreds of people asking you already, and how many could you get to?—until all the faces blur together and you end up wishing you couldn't do anything just so there'd be less depending on you."
