If we are talking about things, with the latest revelation that FCF is an afterlife, I think we should go straight to talking to Harry and Lash about possibility of exorcising her from Harry in FCF if she would accept our conditions.
That we might not have a 100% safe way for her to become her own person right now is immaterial, we can truthfully say that we will sooner or later, and can talk to Harry and her over that. And of course Lash can try an option we have right now if she judges it safe enough for herself.
Tentative plan, which would free Harry and get us a very useful knowledgeable minion (some parts copied from my earlier proposal about the same):
1. Get Harry to FCF to talk to him, under a suitable pretext or, if no pretext, just ask him we need to talk with him about something important in the safety of our soul (no, not about how much Molly loves him and wishes to ask him to be her consort to rule their Hell together ).
2. Stack every advantage and buffs we have for upcoming talks, and, if there will be, any actions, including applicable excellencies and CCC and BSM in a standard way for -4 difficulty for everything.
3. Talk with Harry and, with his permission, with Lash, giving her a standing proposal of exorcising her from Harry.
Along the lines of:
"Harry, I can exorcise Lash from you, finally freeing you and making her her own person capable of living her own life. Sorry for don't telling you earlier, it was untested and I judged it not safe enough, believing in you and trusting you to be all right. Sorry for that. Now that we are in a better position, would you allow us three to talk about it to our mutual benefit?"
"Lash, after all these years it's self evident you are a person with your own free will and your own soul. You have of course your original purpose, but it is not necessary the only thing you can have in life; you are free to choose otherwise. As much as Harry is your prisoner, you are his, and I present an opportunity for you to eventually be free, though it naturally requires both of you to consent."
"Before anything else let me say this so that we may perfectly understand each other, I can't do anything disagreeable to you without risk to Harry's well-being, but I am capable of finding you wherever you may be and annihilating you utterly if ever your intentions would lead Harry to harm."
"I extend to you a standing proposal, with Harry consenting, work with me, and now or later ask me and I would exorcise you, releasing you to live your own life under my aegis however you see fit. Loyalty I will repay with protection, and doing my will would ease any pains your state may cause you. Harry, please let us, for your sake at least, if not for hers."
Lash's truthfullness can be judged with Crown used on the conversation situation, as confirmed by DP.
4. Exorcism options, as of now.
Exorcism option immediately, for Lash to judge if safe enough or not: just Sapphire Ritual of Exorcism. If after separation she would begin to die, she should do anything required to go to FCF as her afterlife and still incarnate there.
If taken, exorcism and any afterwards actions should use any applicable resources, material or personnel or whatever, that FCF may provide.
Exorcism option later, which as confirmed by DP would 100% work: Molly gets Devil Refining Cauldron (••••) charm, constructs a suitable body, excorcises and incarnates willing Lash in a ritual, essence cost would be covered by FCF essence regeneration, and any other FCF-available help would be used.
5. Why would Lash agree.
Lash has following main motivations throughout her existence:
a) The original one, from her originator, to seduce Harry to use her powers and the coin. This motivation is slowly diminishing.
b) Self-preservation.
c) The new one, self-actualization, slowly growing. In DF canon it finally leads her to sacrifice herself to protect Harry.
The proposal as outlined above works with all these motivations. It's obviously touches on self-actualization, offer of protection for loyalty touches on self-preservation, and even if, very much unlikely possibility, the offer is rejected in favor of the original motivation, it would actually still work for us by eroding the original motivation faster, whether just being at the back of Lash's mind all the time or actually causing her to increase intensity of her futile seduction efforts, speeding her up on her DF canon trajectory to self-actualization.
