I doubt even Harry's enemies on the Council would want to hash out their problems with him during PT. The Council would hate showing disunity or weakness in front of the assembled who's-who of the Accords powers even more than they hate Harry. With all the other powers around, it's a better opportunity for trying to manipulate Harry into a duel with someone who overpowers him. But taking him out in-house is better done later and not in front of so many witnesses.

How? He didn't exist yet so there was nothing to link the spell to him and he didn't even have a true name yet. The person who cast the curse didn't even seem to know he existed

I'm not sure the entropy curse needs a blood / hair / name link like regular thaumatugry. Outsider magic might just be alien enough not to need it.

I'm not sure I buy it being directly targeted at Harry and Margaret dealt with Lea to die instead. But Raith might have been hoping to get Maggie Sr. before she could realize her angle on the breed-a-starborn plan.

Dresden is a series focused on Human forces. Alera introduced us to a galactic threat in the form of the zerg vord, so maybe (just maybe) this story of with all it's crystal energy and strange beings are to be the Protoss of some giant shared Butcherverse, and years from now we'll all be reading a huge interstellar cross-over tale that is what Starcraft wished it could be.

I suppose the whole etherealists go insane thing is conceivable as a mutation of the law that DV magic has drawbacks but what specific form they take shifts slowly over time.

We dont know who it is.  We have two WOJ regarding Who it is not: it is not the original Merlin, who would not sound at all british he says, and it is not Loki who is suffering the very literal Norse punishment of venom dripping in his eyes.

Given that Jim has also said he'll lie in Q&A if necessary to prevent a spoiler - and "I'm not going to tell you" in reply to asking if the prisoner is the original Merlin would pretty much be a confirmation - I'm putting limited weight on that one.

The only really significant thing is the clue about who stole the litter of foo dogs.

Next AMA I'm going with "would Mouse recognize them again by scent if he encountered them without their disguises"? If yes, the fact that he didn't freak out over Elaine would exonerate her from being Kumori.

Yes.  Morgan probably would.  Because he's a warden.  I'm not arguing all the wizards would.  Probably a lot of them wouldn't.
But a warden, tasked with doing things like shutting down what Kemmler wants to do, enforcing the laws (and will of the Council) probably would.

I can see Carlos potentially keeping the skull and using Bob for good, if he came across it under the right circumstances. It wouldn't be the first time he took the position that the Senior Council were a bunch of overly conservative old fools (mutinying in Changes), and/or that what they didn't know (hunt for the 'Black Hats') wouldn't hurt them.

Harry never shows any sign of corruption from tapping into necromancy to raise Sue (OK Luccio lets him get away with that, but it's still the same dark energy, so...) and he hasn't shown any effects from killing Justin since at least WN (if you think Lash was tapping into it) or since way earlier otherwise.

Raising a zombie animal didn't do anything major to his personality because it's not touching the dark energy that inherently causes most of the worst effects, it's believing on a fundamental level that you have the right to use it to enslave a dead person.

And as for effects from killing Justin, are you sure? Harry reflected in GS that his entire career he's dealt with threats by embracing wrath because anger insulated him from being afraid. His control has improved, but that core trait didn't vanish when Lash died.

See, I don't think what killing Justin did to Harry was simply make him more violent in a random way. Harry's reasoning for why it was ok to kill Justin was rooted in because Justin sent the Walker after him and was trying to enthrall him - it was violence in reaction to a threat. And that's how Harry has been dealing with threats ever since, for the most part.

Aren't the Walkers the Knights to a bigger power? Or did I get that wrong?

No, that's correct. The wording of entropy curse in BR, when Raith's sorceress was summoning HWW Behind, called him an upper servant of the Lord of Slowest Terror.
I think the model is that the Outsiders are servants of the Old Ones that are locked asleep in reality rather than Outside with their servants, and the Walkers are leading the rest of their armies in trying to get back in and wake their lords up.
