It is probably an excessively personal thing to have said. Followups definitely would be.

Iomedae nods, and stands, and leaves.

A part of her wishes Iomedae would have stayed, but of course she has other things that need doing - especially in light of today's revelations - and doesn't have the time or inclination to deal with Alfirin being emotional.

“I’d expect Shelyn will remove the mind control,” says Lilia, “but I don’t expect that to have important consequences. You in the future know how to do comprehensive memory modification but I think none has been done to me.”

She doesn't mean the dominate, which Alfirin already released. "...the mind control?" She dreads the answer she knows is coming, but the details might be important -

“You have a subtle spell that makes all your descendants loyal to you. It’s more like a charm than a compulsion - it’s about liking you and trusting you. I am not sure if it’s operative towards you at all - it’s subtle - and while it’s certainly still operative towards my mother I don’t experience significant changes in my motivations in an antimagic field. It’s more important with children.”

A capable person ought not to be particularly moved by liking or trusting in the first place, and therefore ought not to experience significant motivational issues if their liking and trusting is impeded. Of course it is easy to imagine oneself more capable than one is, but this she thinks she's capable of.

More important with children. Right. "I see. That does seem like something Shelyn would remove."

'Alfirin' is bothered by the prospect of its removal, and more surprisingly wants Lilia to notice that she's bothered by the prospect. "You can put it back afterwards."

"I cannot, actually. And it does not seem like it would be very impactful. And I do not want to."

She does want to know what her mother wants; she can't do what her mother wants done, otherwise.

It is kind of - annoying? upsetting - for her mother to want different things than the wiser, older, smarter version of her that Lilia knew. It feels like an error - if you know what you'll want later, why not go ahead and want it now? - but of course it isn't, not really. If Lilia learned that in a thousand years she would betray her mother this wouldn't inspire her to do it. 

But if her mother considers her better, wiser, stronger self to be in some respect a failure, then - Lilia is also a failure, because it is that wiser, better woman to whom Lilia is devoted. 

No, that's silly. A better lens on it is just that, if you're sending someone to be a spy in Infernal Cheliax, you want them to be loyal to you in a hundred ways, because they will eventually be tortured to death and damned in your service and the most important quality they can possess is being someone who will serve you even once this is inevitable and even once it's underway. Mind control extends how long someone can hold out under torture, and is useful for that reason alone. 

Now her mother serves the Shining Crusade, and wishes to be regarded as virtuous by paladins, who disapprove of mind control. Having a loyal and obedient servant isn't objectionable to paladins - Iomedae has many - but She doesn't mind-control them. Her mother in this context is better served by the service Iomedae's slaves offer her than the service Asmodeus's slaves offer Him; no less absolute, but differently justified. There is no need to frame these preferences as in opposition, no need to answer whether the passage of time made her mother wiser or weaker; it's just different circumstances.

Iomedae sends her slaves to Hell, when She wills it, and they go out of the conviction that the doing is right, that the work they are a part of is a work so good that their absolute destruction in its service should hardly be regarded. If you think about it from the right angle it's actually a more devoted sort of service.

"I understand," she says.

Arazni brings an alien ninth circle priest of Shelyn to do the miracle. It’s a crystalline radiantly beautiful thing that is very hard to look away from. 

Lilia’s memories have not been modified; with her enforced loyalty to her mother gone she has only her ordinary loyalty to her mother, the center of the world, her creator and shaper, of all the beings strong enough to deserve to command a Lilia the one who bothered to sculpt one.

She thanks the dazzling crystal thing and the dazzling crystal thing compliments her outfit. 

When it's gone she smiles at Alfirin. She won't speak freely, not in front of Arazni, but the smile should convey enough. "I notice no different in my memories or my aims. It is possible I've had restored some memory of some specific secret I don't contemplate often; that might take some time to notice. But nothing important is changed."

"It seems like that settles that, unless there were other tests you wanted to run?"

"There's no other test I'd want to run. 

Thank you for warning us.”

Lilia absolutely did not warn her and will graciously accept thanks for having done so. “I only hope that if the future I saw was real it is straightforwardly averted.”

“Do you want a reward?”

…Lilia actually hadn’t expected that. What with how, again, she did not, actually, warn them. She warned Alfirin, and she - hadn’t expected the degree to which this just counted to the Crusade command as warning them, because Alfirin is their trusted ally. Even though that’s the whole point of Alfirin’s immortality, that she can have trusted allies who don’t need the whole picture - “I hadn’t thought about that,” she says truthfully. “Can I answer you later?”

“Of course, but not too much later, I might be dead.” Arazni smiles warmly at her and heads out

Lilia raises an eyebrow at her mother. “Do I want a reward?”

"That seems like a question for you more than a question for me."

"...even if it looks better to ask Arazni for something for me, I'm not sure towards what purpose I should presently equip myself."

"Have you never had purposes or wants of your own?"

“I have not. I suppose when I was a very small child I like most small children wanted rewards and the absence of punishment and to stop being a small child.”

"Are you expecting me to direct you towards some new purpose?"
