So unless the Denarians take direct action against the White Council, I really don't see these two bodies coming into direct conflict.

Also, Tessa's opening pitch to Harry in SmF was rooted in offering him pretty good terms to avoid an incident with the Council. Harry figured she was lying, but most wizards would be pretty happy to take that deal - and she might have actually meant it with some random with less of a reputation for obstinacy.

One wonders how much of Nicodemus' boasting about being the dominant player and the Fallen following his lead is sheer self-deception.  Anduriel may be laughing his shadowy ass off whenever he hears Nicodemus go into that rant.

My sense is Anduriel is probably OK with Nicodemus calling shots over the other 29, because they're an exceptionally tight team in terms of overall purpose, and a badass host helps his standing among not uniformly trustworthy company. (Side note, I wonder whether Anduriel is the de facto head Denarian because he has a long-lived badass host who's been around since the beginning, or because his eavesdropping is that powerful? If Nic bought it, would Anduriel still be at the top of the heap as soon as he got a new host, or would another one move up?)

But the very act of Falling requires a certain psychology. If he's unwilling to follow orders from TWG himself, there's no way he's willing to the led by a mere mortal.

The holy swords aren't powered by an enchantment, so warden blades aren't going to unmake them that directly. On the other hand, if Michael was driven by vengeance rather than 'on mission', Amoracchius is just a piece of metal.

My guess is they'd just clash as material swords in that case. Although if Michael rendered his sword vulnerable by acting improperly, Morgan's charged attack (I'm thinking of the technique he used to cut through trees in a single blow when he went after Harry in DB) might still affect it.

So if someday another jerk-nozzle like Morgan comes along with the right Fanatic'O flavor he might be able to use Morgan's old sword.

The curious part there is Harry eventually realized Morgan got the way he is through seeing a century-odd worth of really horrible things. He probably didn't start out as the 'burnt out cop'.

So if his personality changed over the decades to become that, did his sword adapt with him? Did Luccio have to keep retuning them as the owners' personalities changed?

Personally, I'm not yet convinced Anduriel was unable to rescue the coins dropped by Lasciel and Ursiel.

•   Mab could NOT have sent the fetches to kill people at the con.  She is not allowed to do this due to the rules of Fey Queens.  Either someone else gave the command or the Fetches were killing on their own.

She can't command specific deaths. But hypothetically, she could command them to visit the mortal world at a particular time and place, and just rely on their naturally predatory nature to get the job done. Though I tend toward Nemesis as a more likely explanation for the fetches behaviour.

•   The fetch knew enough about Molly to trick her into inviting them into the house (not a high threshold, but not complete ignorance)

Actually, no. There's a WOJ that Harry surmised wrong there - Molly didn't invite them in, they just powered through the threshold. Which makes them freaking beastly and/or N-fected.

•   Thorned Namshiel was involved in the attack on Arctus Tor

Not that it argues against Namshiel's presence (nothing says only one attacker used Hellfire), but I would note that Rosanna's absence from SG was also quite conspicuous. Also keep in mind Nic's comment in SmF about being sure one of the two women was "our own Judas".

Personally, my theory is Tessa is the ringleader for 1-3 traitor Denarians, but she's succeeded for the time being in framing Rosanna as far as Nic is concerned.

1)Harry's Bargains. Per WOJ, that third Favor is still in play, but largley moot because the Winter Knight thing basically gives her the ability to ask infinite favors.  The theory goes that the Last Favor might be used in a case where Harry might need to be sent after somebody that, per the terms of his Knighthood Bargain, she cannot send him after, specifically a Loved one.  So if she needs to send him after Molly or McCoy or Thomas or somebody she cannot order him as her Knight, but she can still ask the Final Favor.  And since the terms of those Three Favors said that afterward he'd be entirely Free of all Sidhe influence, all obligation to Lea and Mab (by the technical wording), the theory is that it might negate bargains made after that including the Knighthood.

Did Mab actually accept his demand for an exemption on having to kill a loved one? As I recall the passage, she initially said the Knight would kill whoever she damn well told him to. Did she ever explicitly concede that clause to him?

And I thought Harry said he was a far better fencer than swordsman. That he had reach enough to hit from the next county over.  Though I thought a fencer WAS a swordsman.

Fencing is to swordsmanship more or less as boxing is to MMA - it's one discipline in the field, but as a form it limits a lot of the techniques one might use if practically trying to hurt an opponent.
