Even though I didn't write the OP, I will say why I think it there is a good chance it will turn out to be correct.

IMO, Harry doesn't have a clue how to raise his spirit child or maybe only one clue.  Maggie can have more or less normal conversations with Bonnea because she is a child.  She doesn't see anything unusual about interacting with a talking skull because Maggie doesn't have a frame of reference to inform her what Bonnea really is and how different Bonnea is from a mortal like herself.  So Maggie treats Bonnea like a friend or younger sibling she's looking out for.  Harry knows what Bonnea is and treats her with kid gloves.  Near the beginning of Peace Talks Harry says that Bonea, "is someone to be carefully managed."

Managed, not raised.  I suspect there is a problem with that single minded kind of thinking.  I think Bonnea will need guidance; in some respects, just like any other child, but not exactly because she isn't a mortal and her potential for doing harm is so much greater.  We all know Bonnea isn't a ticking bomb, she's wet dynamite.  With the innate knowledge of a wizard and a fallen angel at her disposal and with the added difficulty Harry will have teaching a spirit of intellect about ethics and morality; if someone, something or a dangerous situation gives Bonnea the right push or wrong push at the right moment, things may go boom!

Harry probably wants to keep Bob as far away from Bonnea as possible, because Bob would want to help Bonnea and that could be extremely dangerous.  However, my guess is Harry needs Bob's help.  Harry needs to understand what it's like to be a child who is also a spirit of intellect, to help him make better decisions raising Bonnea.  Bob's involvement will accelerate Bonnea's growth and when the right or wrong situation pops up to push Bonnea even further, she could go from zero to sixty.

P.S. At some point in the near future, Harry might need Bonnea to go from zero to sixty.  Ignoring theoretical political alliances Harry might make in the future, without becoming an immortal himself or learning some powerful new magical techniques, it's difficult for me seeing Harry becoming much stronger or a more potent force than he already is.  Bonnea's knowledge could be a real difference maker for Harry.  Bonnea herself almost certainly has the potential to be more powerful than Bob or Bob's blue counterpart, evil Bob.  If this doesn't happen in the next few books, I think it almost certainly will in the BAT.   

Cite, please?  I don't recall this, at all -- that the Red Court was ever composed of half-turned.

The Red King and all the LOON's were full-Ramp, and AFAIK have been so for a long time -- long enough ago that they were well-established as rulers in Mesoamerica when Cortez arrived.

I recall WoJ that they got so powerful by somehow using their venom to addict entities previously worshipped as gods by mesoamericans, and drain that power to use for themselves.

I don't recall this, either.

It's quite simple, but perhaps I didn't state it clearly.  Every member of the Red Court was at one time a human who was bitten by a full member of the Red Court who had authority to make new members.  (Side note:) Apparently, Bianca didn't have permission or authority to do this until she was promoted in Grave Peril.  I don't recall if it was Thomas or Justine who told Harry about her new ability or authority to create new members of the Red Court.

However, before becoming a full fledged Red Court vampire, each individual is only half-turned.  You already know this from Susan's example.  Some people who are bitten might make their first kill the night they were bitten while others hold out for years, decades or even centuries, like Martin.  So, every member of the Red Court was once only half-turned until they made their first kill.

We don't know if the Red Court could infect a non-human with their bloodlust.  We haven't been told if this was possible.

I think the Ramp's are creatures of the Nevernever, natively; I note several similarities in the descriptions of the native-form (without fleshmask) Ramps, and the Ick... and suspect them of being related entities.

It appears that after writing Storm Front Jim retconned the Red Court.  In SF, Harry mentions that vampires are creatures of the Nevernever and that it takes most of their energy to simply maintain themselves on the mortal plane.  I don’t remember if this was after Harry had his run-in with Bianca or if this bit of exposition occurred before that point in the story, but she was the only vampire we meet in SF, so Jim; through Harry, told us the Red Court are native to the Nevernever.

However, this bit about vampires being native to the Nevernever has never been mentioned again.  It really doesn’t make sense anyway.  The Red Court were once humans who got half-turned until they killed someone and went full Rampire.  Maybe whatever created the Red King was native to the Nevernever, but since that time all the members of the Red Court were humans that had been turned.  If a member of the Red Court could infect a non-human, we haven’t seen one or been told it was possible to do.

What would the White Court of Vampires have to do with Lea and Justin?  Yes, Lord Raith murdered Harry's mother, but I don't see any evidence that he had anything to do with either Lea or Justin.

I should have explained.  It's manipulation on a scale that someone like Lara Raith could admire, though Lara or any of the Raiths would have used a different method to attain it. 

Lea makes a deal with Margarite LeFay to protect Harry, then while still fulfilling her given word, either allows Harry's father to be murdered or does it herself as part of a deal with Justin DuMorne.  DuMorne thinks he has won a great prize but Lea has simply offloaded the drudge work of teaching Harry basic magic skills until she can find a way to dispose of Justin.  A break between Justin and Harry (Did Lea have anything to do with that? Meaning, did she have another deal with whoever summoned HWWB?) allows Lea to get Harry to remove Justin for her and to top everything off, it allows Lea to make a binding deal with a young, desperate and naïve, starborn wizard Harry.

P.S. New topic on the same character.  Thinking back to the dénouement of the Battle of Chicken Pizza in Changes, Ebenezer approaches Harry and Lea and asks her to leave so he can discus "family business" with Harry.  Ebenezer knew who Lea was and he knew that she knew about Eb and Harry's familial relationship. 

It is one thing for Ebenezer to recognize The Leanansidhe; Lea is a very powerful figure in the Winter Court and Ebenezer has been around long enough to have had some experience with the fae, but as was pointed out in Battle Ground, Eb doesn't believe in casually dropping any information about anything, especially family.  Even if Eb guessed that Lea knew that Eb was Harry's grandfather, he still wouldn't have mentioned it, he might have said something like "White Council business" instead.

What I want to know is, how did Ebenezer know that Lea knew?  Margaret LeFay was on the run and probably realized that her time was running out when she made the deal with Lea to protect Harry.  Ebenezer wasn't there.  Ebenezer didn't visit Harry in the orphanage, Lea did.  Even if Harry told Eb about the deal he had struck with Lea to defeat Justin; after the White Council put Harry under the Doom of Damocles and under Eb's guidance, Ebenezer wouldn't have known how much Lea knew about Harry's family.

Did Ebenezer make his own deal with Lea?  I'm not speculating what such a deal might have involved, but those two know each other and not just by reputation.  It suggests something more is going on here and perhaps something important. 

My personal theory is that since we now know hhwb wasn't sent by Justin, he was sent for him.

Which meant that Justin (who had hijacked Maggie's Starborn plan for his own ends) needed Harry and Elaine ready early, which meant abandoning traditional brainwashing/conditioning in favour of Magical alternatives.

Unfortunately for him, hhwb was able to turn Justin's anti-outsider wmd against him.

This is a pretty good guess, but I also question it.  I mean, how do we know Justin didn't call up HWWB?  I like the idea, it does explain why Justin decided he needed to enthrall Harry at that particular moment rather than slowly indoctrinate or slowly enthrall him, but I don't think we have proof the Walker was called up by someone else.  Also, if Justin didn't call up the Outsider, who did?

If you follow this idea to its conclusion, it means there was another player in the game.  A person Harry currently has no clue exists.  Actually, it is possible that Harry has met this person, but he isn't aware that this person played such a significant role in his own life.  You also have to ask why this unknown party called up HWWB, because I don't think it would have been just to go after Justin.  We know that Harry meeting and defeating the Walker is what made Harry decide he had to stop running away from Justin, but did the party who called up HWWB expect that to happen?  That would mean they expected Harry to defeat the Outsider.  Perhaps they were testing Harry, to see if he was all that. 

This was also the event that gave Lea the opportunity to offer Harry a deal, power to defeat Justin in exchange for Harry's loyalty or service.  However, Lea told Harry in Ghost Story that she didn't witness his confrontation with HWWB.  That is why she wanted to hear the story of young Harry's confrontation with the Walker.  I'm going to have to reread that scene between Harry and Lea to see if that is actually what she said or if she was playing word games with him.  Even if Lea didn't witness that confrontation she could have been aware of it if she also had made a deal with this phantom person who called up HWWB.  Than again, that might have violated her agreement to protect Harry so perhaps she wasn't involved.  I suppose it depends on how her agreement with Margaret LeFay was worded.  I find it hard to believe that Lea wasn't looking for an event that would cause a break between Harry and Justin.  Therefore, it is highly likely that Lea knows more about this episode than she let on in her conversation with Harry in Ghost Story.  Of course, that last statement depends on there being another party who called up HWWB.  This is either a really great idea or a rabbit hole to nowhere.

I think there are 2 possibilities:

#1
After reading Peace Talks, he did look for Harry and he did find him. But he didn't take him in, because he was taken care of. I think he planned on watching, if little Harry started showing magical talent at some time. If it never happened, Harry would never have known him. If Harry showed talent, Ebenezar would have taken him as apprentice or apprentice him to an other wizard he trusted.

But then Harry was adopted by Justin. Maybe Justin even got a tip from Ebenezar. During this time Justin was still supposed to be a respected warden, so good master material for Harry. But why did Eb approve of Justin not introducing his apprentice to the council?

#2
After Malcolm died, Lea took care that Harry disappeared from all mundane and magical screens, because of a deal Margaret made with her for Harry's protection. So nobody could find Harry. Not even powerful wizards with blood relation. Justin was just screening the orphanages for weird incidences. That's how he found Harry. It was the impossible long jump.


I think #2 is more likely, considering Morgan's journal entry. I guess, Justin still appeared at council meetings, but never told any other council wizard about his apprentices. But I also can totally imagine Ebenezar knowing where his grandson was, but just not interfering. Like he seemed to have done with his own daughter.
I hope this will be cleared up some day.

I won't be surprised if eventually we are told that Lea is the reason why Justin found out about and got ahold of Harry.  Now that I think about it, it is also possible Lea knows something about Elaine's origin story.  However, there is nothing in the novels, short stories or Q&A sessions with Jim that I've watched; and I've watched a lot of them, that remotely support this second idea.  It's pure speculation.

About my first and main idea, I keep thinking about a WoJ that states that Margaret LeFey didn't make the best possible deal she might have made with Lea for Harry's protection.  I have previously assumed that Margaret got Lea to agree to protect Harry from outside threats but didn't realize that Malcolm Dresden might also need protection.  In other words, Margaret thought that because Malcom Dresden wasn't a player in the supernatural world no one in that world would have a reason to target him.  Then again, perhaps Margaret did get Lea to agree to protect Malcolm Dresden, from everyone except herself.  I theorize that Lea either stood by and did nothing when Malcolm Dresden was murdered or she did it herself.

Lea's deal with Justin could have started when Malcolm Dresden was still alive.  Remove Malcolm to trap the boy in a system where he could be easily monitored and not wander the country with his father where anyone else might find him. Once Harry manifested magical abilities, Justin was suited to teach Harry basic use of magic.  Malcolm couldn't teach Harry about magic, so he was probably always seen as expendable by Lea. 

In my version of events Lea knew exactly what kind of person Justin was; even if the White Council didn't know, or fully know, about Justin.  She always planned to turn on him at the first opportunity and gain the use of Harry's abilities for herself.  Justin probably never realized that Lea had been training Harry; apparently to just believe in himself, when Harry returned to face him.  It's a series of moves that the White Court of Vampires would approve of.

I wondered about that myself.  It seemed a bit too Horatio Hornblower to me.  If they had something that looked like a mid 20th century artillery piece, that would have made more sense.
