I ... guess this is a further riff on "Sword of Truth" (the sundial statue "Life"?)

I'm pretty sure that Jim pretty-rigorously avoids politics (as Harry, he denigrates all politicians equally, just as politicians, without ever calling out specific policies).

And your own remarks in themselves seem to be straying well-into the explicitly-disallowed territory... even if you're "just making a joke" or "forgot the /s" or whatever.

I don't think so, nothing political in referring to other fantasy series, and the Dresden Files is all about war, peace, good, and evil... You really can't discuss the Dresdenverse without getting into those things, the world has been thus since the beginning of time..  In my opinion no one's toes politically or religiously have been stepped on..

I don't think we know the form(s) of Justine's mental illness, no (noting that multiple-diagnoses are very much a thing).  It's not clear to me that Jim does, himself.

I doubt Jim will specifically write it as "hallucinations" though -- that really muddies the whole "free will" issue, which is thematically-important to the Dresdenverse.

Why would it?  You think that Nemesis cares about "free will?"  And though not by Nemesis, but by one of the Fallen, Lasciel was perfectly happy to use a hallucination, i.e. Shelia to seduce Harry into taking up a coin.  The taking of the coin itself might be an act of free will, but getting him to that point goes against his free will, as we saw Harry's reaction once he realized it.  Why wouldn't Nemesis use Justine's mental illness to produce hallucinations to fool her into accepting an Outsider take over of her person? Do you think Justine was really thinking clearly when she agreed to that?

I don't necessary _expect_ to see this in Twelve Months.  But I think it would be interesting it JB went that route.

Imagine if on the other time line, because of Harry's choice, the Red Court managed to get enough of an advantage to break the White Council.  So there's either no Council over there, or it's weak and in disarray and can't fulfill its purpose.

It could serve as an illustration to Harry why the Council is so important, why even his allies like Eb and Injun Joe and so on refuse to risk disrupting it.  Seeing a world without the Council might give Harry a little different perspective on this world.

Yes, everyone is so excited about the prospect of seeing an "evil Harry,"  but Jim has been there done that with an "
evil Bob."  I agree with you if it is about Harry making the wrong choice at the end or towards the end of Grave Peril, it's the consequences of that that is important.  I think back to what Shiro told Harry about his decisions at and after the party and after that led to the Red Court declaring war on the White Council before they were ready to fight that war.  So many things flow from that decision, the duel, Shiro's death and asking Harry to be the custodian of the Sword of Faith, Eb dropping a well aimed satellite, the conception of little Maggie, the wiping out of the entire Red Court..   

And because there is a confluence in Chicago -- all of the same "dark powers" that Harry noted are still coming to bear, there -- I think Michael will more-often be Guided to Murphy's aid, than he originally was in the first few books.

Or not, Michael wasn't guided to her aid in the first few books..  I go back to the original assumption that everyone seems to have, and since I don't keep up with them I don't keep up very well with WOJs, is the other Harry is an evil counter point to our Harry.. If nothing if changed because of that, shrug of shoulders, Harry in the other universe is evil..  However I don't think so.. If one goes by "It's a Wonderful Life," all matter of things go wrong because our hero was never born... One prime example is at the age of 10 he saved his brother, who grew up to in the Medal of Honor because he saved hundreds of men on board a ship if I remember correctly... If he hadn't been saved, then not just he would have died, but the hundreds that he saved would have died, and maybe hundreds more children who would have done great things were never born.... It goes on and on like that..  It isn't about the now evil Harry, it's about the wrong choice that was made that really screws things up in both timelines.

It's in the chapter immediately following the one where Susan dies; Harry talks about the fallout from the destruction of the entire Red Court; so, not in-the-moment stuff or stuff Harry personally saw/experienced; but Harry telling us about things that he heard of, broadly.

That doesn't mean anything as far as something "human" remaining in the fully turned.  Bianca the main example we have was full
RCV, nothing human about her, but she appeared human to the eye and could be very charming, so could others in the world, but that doesn't mean that anything human remained of them...

So long as he wears the Kringle mantle, he's subject to Winter.
But he appears able to put it on and take it off at will.

More like an associate of Winter or with Winter, I doubt that Kringle would take a direct order from Mab for example, or that she would give one.. I think they actually agree on a lot of stuff, I also think because of his multiple mantles that he is way too complex to be a subject.

I believe that there is an old WOJ that states that Lara's control of the White Court is slipping because Papa Raith is becoming more unstable. We know that some of Twelve Months will be dealing with the White Court. I think it is conceivable that there will be a loss of control of Papa Raith and Harry will have to help Lara set herself up as the White Queen. She will no longer be ruling from the shadows. This could dovetail nicely with a hunt for Outsiders in the White Court that other posters have mentioned.

No hint of that so far, however we haven't heard a word from the other branches of the White Court since "White Night," so it is possible that the Raith family will find itself on the outside looking in.  Lara may find herself with her father incapacitated, Thomas and Justine now gone, isolated and she may have to turn to Harry, and not from her usual position of strength.. Or with the help of whatever is protecting him, Papa Raith makes a huge come back, plus perhaps many in the family didn't like the fact that she chose to fight against the Fomor in the battle for Chicago.  Then there is Toot and Za'Gard, they haven't forgotten their treatment at the hands of the White Court, I doubt they will remain passive in all of this.

It would be interesting to see how Kringle interacts with the Mothers.  JB said at one point that pretty much everybody in Faerie is subordinate to the Mothers, but is Odin?  I mean he's not exactly 'of Faerie' in his own identity...

I doubt that he is because he is a "god" in his own right.
