Lilly's access to Flow means she will come around on accepting Valerie's past a hell of a lot quicker than most people can emotionally.
By the sounds of that {Affective Radiance} has its work cut out for it. As Lilly delivers her speech to her followers it'll have to churn away converting all that negativity into acceptance.
Hopefully by the time Valerie is healed all the emotional pain will have been burned asunder by [Shine, my Gentle Heart]. Otherwise, Lilly will be in a whole lot of trouble with her minions and they may turncoat as well.
And if Valerie is any indication, there may be more borderline criminal, if not outright criminal, people Lilly will adopt. Which she will have to convince her followers that they are good now and should be accepted. Marigold is quite infamous, I recall.
On the other note. Since Lilly's [Tower] is all about messing with souls and ethoses. Having Zach gain his ethos while in contact with Lilly's domain should help things along. Like with [Meta-Ethic Control} for example. Gently easing him into his power.
But note that Domain Min/Max: 1cm / 20cm ::Grasp:: 8/10
20 cm is enough to cover a heart, if done slowly overtime. How much would Lilly need to envelop Zach fully in her domain? And how much would we need to expand the domain Min/Max size. Using MR to upgrade the domain allows Lilly to double the size and make any future expansion bigger.
However. Could Lilly, if she takes her time, over the course of a hour envelop Zach with her domain? Wriggel her domain beyond 20 cm. Maybe by using {Stray Vector} or {Remodian Geometer} to make the space within her domain overlap.
I come to this conclusion because of the talk from "Lotus Ritual", and the [Tower] sounds like something that can reduce the load by doing a lot of heavy lifting in the formation of the Integration Vector, connecting Ethos and soul.
Edit: heh, I misremembered Lotusing Ritual as Load Reducing Ritual.
On the ritual, yeah I think it's a placebo sort of thing, it works in some cases but mortals don't get a view behind the scenes. Probably simple superstition on their part. But what the hosts of the powers want, feel, and believe plays a role in what Ethos they get. Someone with low self-esteem may pick something unimpressive, simply because they don't think they are worth more for example. Even if they have premium allocation or something along those lines.
