"Yes. On foot, though, flying is I think seldom going to be cost-effective in these situations other than for a split second to arrest a fall or something."

"If I were to drop you from a high above could you land without much cost than? Also, is it possible for you to take items off from a person without them noticing, for instance, that crystal sword Lord Metcalfe had?"

"You can drop me, yeah, my flight can cancel acceleration well - though not in the dark, because I need to see to know when it should kick in and out for maximum efficiency; if I can't see where the ground is I'll hover and stay that way. He would notice he didn't have it any more, and there'd be a moment while I was pulling on it before I 'had' it where he'd be able to feel the pull, but if he weren't holding it, I could take it without him feeling or seeing anything but its absence - this might want practice, though, I don't do a lot of pickpocketing."

Nod.

"I'm not usually a fan of theft but I don't think that particular item belongs in Lord Metcalfe's possession. Can you light a signal torch and prevent people other than me from seeing it?"

"Yes."

"What happens if you light it right in front of someone and it's bright enough to blind them?"

"I don't know what would happen if it were bright enough to damage their eyes, I haven't tried that. But they wouldn't visually detect it."

"Hm... I do think our fight today would have gone better if the signal flare I saw was held by Metcalfe than by Viper - I only had the one chance to take someone out by surprise and Viper seemed like the weaker of the two. Plausibly it would be wise for you to spy on some villains, select an enemy, and signal for me to fall on whichever seems strongest among the empowered."

"I might be bad at guessing that, I have all my instincts trained in a completely different context."

"Even distinguishing between empowered and not would be helpful."

"Which I can apparently do by poking each of them for a moment."

"Oh, true."

"And can hold a light and write out whatever intel I have to hold up for you."

"It would have to be written in a rather big font."

"True. I don't suppose you have a great way to create lights in different colors?"

"You could create a bunch of jars of colored glass and put whichever one you wanted on top of the signal torch?"

"Wouldn't that smother it - I don't deal with fire per se much, we have other ways of doing lighting in my universe."

"It would smother it but not immediately, and you can leave space for some amount of air flow to prolong that period."

"Okay, colored glass caps for signal torches to communicate a handful of possible messages about something. Or - semaphore? I don't actually know semaphore. I don't know if it's even been invented yet. I can also just, like, yell, especially if there aren't too many of them."

"There are semaphore systems going back to ancient Greece and I have three of them memorized, though they aren't ideal for our purposes and would have to be adapted. Yelling would probably only work if it was fair weather as well, if I am to be relatively high up."

"Is weather not also a limitation of torches? - I will need to practice lighting them. I have not ever tried to start a fire of any kind in my life."

"Signal torches are made specially to work in a variety of weather. Also that's true of me as well but I can ask my head maid to instruct you."

Nod nod.

Lucette can set to work on scheduling the various tasks that will need to be accomplished before Haru is ready to go on patrol - he'll need some sort of unusually light armor, a signalling apparatus, they'll need to work out some variant of semaphore, and he'll need to learn how to light those signals as discussed. She can also recommend he read her copies of the London Gazette, specifically the articles on criminal activities which she's annoted with her best guesses as to the details of the abilitities and activities involved that may only be hinted at by the writer. 

And of course he'll still have to leave time for dancing lessons and galas and various midday lunches and diversions. Unless he objects she'll put together a very detailed color coded calendar of these events, incorporating time for the less public activties which can go in the a second separate calendar.

"... possibly I am getting ahead of myself but I've had my own schedule prepared for months and I'd quite enjoy working on another one."

"I wouldn't dream of preventing you." She can have her hand back for all this.
