It's possible that it was Lea that made the promises to Margaret that her child would be protected, and then failed to protect her. Harry would be, and is actually not happy of being deprived of his mother from birth. Also though I think it is more or less clear that Eb kept away from Harry after Malcolm died to protect him, it could also be that Lea had a lot to do with him not even able to track young Harry after he was orphaned.
No, that was
absolutely a Lea/Margaret bargain: the "Faerie Godmother" bargain to protect Harry, made before he was born (because she died in childbirth, and was busily Death-Cursing Raith (so no bargain could be made at that point)).
Margaret still survived a wrathful Lord Raith as she fled from him, and onward through meeting/courting Malcolm. It is this period that I think she had some separate bargain (with Lea or Mab) to keep her safe from Lord Raith's revenge; she would have needed that in place from the moment Raith realized she had fled. I suggest Morgan being "unfindable" (via Titania) tells us
exactly how Margaret kept herself hidden: a major Faerie Power stepping in.
But Margaret gave up her own safety in her bargain to get Harry a Faerie Godmother (and that Harry-centered protective cover over
her ended when Harry exited her womb).
... Yes, and no, Harry has asked Marcone's help on occasion, but using him more than "working with him." Actually they were using each other, Harry, because he needed Marcone's muscle, Marcone because he wanted to use Harry as a door to get him into where he has gotten. If he hadn't been involved with Harry I think Marcone would still be merely the crime boss he was when we first met him. After meeting Harry he realized the the supernatural world was key to even greater power. As far as Mab goes once she bought his contract from Lea, Harry didn't have a whole lot of choice. That was the whole point of her making him impale his own hand on the letter spike, while yes, Harry continues to try and do it his way, in the end he has to go along. Up until Changes, Harry never exactly worked with Lea either, he was more afraid of her than working with her. Harry didn't have a choice to go with Nic into Hell if you will recall, it was under orders, not only that but Harry and Mab had their own adgenda.
The point though is that -- if necessary -- Harry can and does work with people/entities that he distrusts... and even passionately hates. So even if Harry thinks Lea had something to do with his mother's death and/or his father's -- it's still possible (after the frst shock and rage) that he'll be
able to work with her, if it's truly needed (such as to protect his daughter).
... Mab may have chosen Lea for those reasons, but Lea's ambitions went beyond that under the influence of Nemesis, her accepting the Knife for herself at the party and not on behalf of her Queen is telling. That wasn't the work of a day or two under the influence of Nemesis, I believe it was subtle and Lea wasn't aware until it was too late, by the time she did and confessed to Mab, it was too late to save Maeve who perhaps was the real target
I agree with almost all of this; but I think Lea's ambitions were
always to kill Mab and usurp her Mantle. That ambition is
why Mab chose her in the first place!
What Nemesis did, was allow Lea to
cheat. To use tactics/methods forbidden by Winter Law, that Lea normally would never have considered (and possibly been unable to use, 'cos Winter Law is pretty hardcore like that -- sometimes more "physical law" than "legal code").
Maybe Maeve was the "real" target; but maybe it was Mab herself!
Lea s
Mab's Handmaiden, after all; not Maeve's.
But I suspect it was a bit more opportunistic than that -- if you Nemfect the #2 in the Winter Court, you get a
huge number of new targets you didn't have before! It's worth taking a year or ten, figuring out your best next move.
... I disagree, while Mab no doubt knew of the Hunger Demon, I don't think she knew that much about it. Remember what Lara said about it's history being a close kept secret among the White Court. I do agree that the starborn/Winter Knight has been her plan for a very long time, and Margaret made it possible.
I don't think we actually have enough info to be sure how much Mab knew by when; maybe you're right and I'm wrong... but as a general rule I think the safer bet is on Mab to know a hell of a lot more than expected, sooner than expected.
I doubt we'll ever know for sure, unless someone asks Jim during an AMA, and we get a new WoJ!
... I sorta agree on Harry, but I don't think we have any clue about Elaine. We know who Harry's parents were, we know the connections and talents of his mother, perfect setup to create a star born future Winter Knight. We know nothing about Elaine's parents or their connections with Summer, if there was one. The only thing so far that made her a possible candidate for star born is when she was born and her talent ...
Elaine's case is "only" circumstantial, true...
but...
Bear with me, as I lay out the logic chain.
1. Mab wanted to get a knight who was a powerful Starborn.
2. To that end, she actually engaged in a "breeding program" to get Harry -- a strong "Salic Law" wizard born (on Halloween) from Margaret LaFey, and guided Maggie Sr. along the "starbabe plan" pathway.
2a. Much of Harry's life was subtly guided by Mab (and Lea, acting as Mab's Handmaiden).
3. But we also know Mab is about all about backups, contingency-planning, etc.
3a. Therefore (and here we get circumstantial), we can be confident that Margaret & her child
were not the only Starborn efforts Mab was making!
3b. My WAG (this portion of it) is that the Mallory's (specifically, Elaine; but also,
her parents as much as
Harry's parents) were another of Mab's plans, to get another Starborn option. I expect there were yet others (because Mab gonna Mab!).
3c. I also WAG that Justin was Mab's pawn in this: Harry was Lea's Faerie-Godchild, under Lea's protection. How did Justin find him? Mab sold Harry to Justin (and no doubt got an excellent price from Justin... for getting Harry exactly where Mab wanted him to be).
3d. If Justin was Mab's pawn (and Mab saw to it that Harry got to Justin) then potential-Starborn Elaine looks too similar to ignore, and like Mab did that one too (Mab/Lea certainly couldn't have
overlooked Elaine at Justin's, so... ) .
(I could also see the whole "Mallorys as Starborn breeders" plan as Titania's work, but I think Mab is the one who's laying long-term plans quite that coldbloodedly. I think Elaine went to Summer because -- at that point -- Harry was a lock for Winter, and Mab has her
Thing about "balanced scales.")
... Possible, but I still think it was a conclusion Margaret came to on her own after being with Lord Raith for a while. I think it very possible that Margaret actually did soul gaze Lord Raith and learned about the Hunger Demon and realized what it was. I also think it's no real secret that at some point the BAT is coming and a leader hopefully a star born one would emerge. Problem with that is until Margaret met Malcolm none of the star born were suitable because they were as bad or almost as bad as the Outsiders ...
I think it's very possible that Mab/Lea specifically aimed Maggie at Lord Raith: she couldn't go to the Edinburgh library to learn more, after all! And (per WoJ) Raith had a major library on the Outsider/Starborn/Apocalypse thing, because he had hoped/planned to be a "major player" in this cycle. But I think Mab(Lea) had planted the
seeds of the idea with Maggie, and then she needed more info (which she couldn't get from "regular wizard sources" (i.e. Edinburgh)).
I suppose it's possible that Maggie learned the Hunger Demon secret from Soulgazing Raith... but it seems
profoundly unlikely. Harry 'gazed Thomas and Lara, Carlos 'gazed Lara... I think wizards soulgazing Whampires cannot be all that rare an occurrence; and yet, the secret is not commonly known to the White Council. Ergo, even Soulgaze isn't enough to spot their nature (which fits, actually -- not even Rashid in the center of his power (at the Gates that he Keeps) can reliably spot them).
I don't think the "coming Apocalypse" is actually all that well known. It's obvious to the Really Big Powers, of course, and a few stupid-lucky wizards who somehow survive repeated poking their noses into the business of Faerie Queens and Denarians and Ancient Gods (like Odin & Hades)... but there's not actually many who survive that level of stupidity! And it's not actually
clear to Harry, even yet.
... Remember what Lash said about Margaret delibrately conceiving a star child with Malcolm because of his qualities.
That's not what Lash said: she said Harry was born for a reason, but not that the reason was Margaret's. I'm sure Margaret had her reasons, but I don't think those are what Lash was talking about. I think when Margaret took up with Malcolm, turned her life around... her reasoning became much less comprehensible to the Fallen.
I think Margaret was just a pawn, and the "real" reason (from Lash's POV) were Mab's & Uriel's reasons. I think that Margaret was unaware of those plans, and unaware that she had been manipulated so badly.

... I agree that Uriel had a lot to do with putting Malcolm in Margaret's path. I think Uriel was well aware of the need for a star born to fight the Outsiders but at the same time aware of the flaws in the star born. Free will still enters the picture, Uriel couldn't make the two of them fall in love, all he could do is nudge here and there and hopefully love and free will would take it's course.
Agreed all 'round.
But I suspect Uriel had a
really good idea what a profound effect Malcolm would have on Maggie. Recall that early-Maggie was actually very idealistic, her "danger" was that her ideals were destabilizing and were unrealistic about "unintended consequences." But she was good-hearted in her goals. Later in life, she seems to have become embittered, cynical, etc.
Malcolm reignited her idealistic flames; Uriel knew the banked fires were still there, they just needed feeding... Malcolm fed her soul.
... Justin didn't even try to be an example for Harry to follow, he had his own agenda as far as either Harry or Elaine goes. Justin didn't care what kind of person either kid grew up to be as long as he could use them for his own purpose.
I know the Party Line about Justin. I'm not certain that this isn't another fake-out from Jim; it's possible that Justin is another "secretly a good guy" figure. But I'm far from sure of this idea!!!
