I think Cowl is the single biggest unanswered question and the one most people are hands down looking forward to the answer to the most... that and the British Prisoner..

I am most looking forward to seeing the accuracy of the Meta Theories (Things like "Dresden Files is just a Wheel of Time style cyclical retelling of the story of King Arthur") with a close second being the resolution of Thomas' current predicament.

[snip]I have wasted hundreds of hours of research and argument.

Agreed

For that matter, I suspect that if Harry would have just shot Rudolph,  the sword wouldn't have done anything to him.  Using magic and The Mantle of the Winter Knight made it a different matter.  I could be wrong on that, but it fits.  Angels can interfere with supernatural threats, but not vanilla mortal technology.

I don't think the Swords are bound like that.  The Denarians are in the coins to get away from exactly that rule, you can't use angelic power to breach free will, and the swords have angels in them to counteract the fallen in the coins.  So I believe the angels in the swords are able to use the wielder's free will to affect the world with their power just as the Denarians can. I think the Angels generally don't because they are Angels... but I think for Harry they would make an exception and stop him from making a mistake that he couldn't live with.

That's probably my theory. I've come and gone under a few names. Sadly I felt my previous works were obviously not up to par organizationally (which hey I'm autistic, it LOOKED organized to ME at least 😂🤦‍♂️🤷‍♂️) so idk that any specific thread outlining it exists.
I have built, a rather large interlaced metatheory based around this and other details but If you have any specific questions however I'm sure they'd jog my memory on whatever info you're looking for.

I am not looking for anything specific, just found the theory interesting and wanted to read about who maps to who and how that informs their relationships and what that means going forward.

The bare bones theory itself can and does actually predict some events in the DF based on previous cycles in fact.

Yeah, that's the kind of thing I was looking for.

I will happily put up with unorganized heap if you have it...

Rudy is Nameless hireling, his goon, his stooge.

"Rudy is Nameless' hireling, his goon, his stooge."
'Rudy is Nameless^ That Apostrophe is important.  In your original post you used the apostrophe for Marcone's but not for Nameless' and the lack of an added "s" when converting Nameless to possessive form makes it harder to infer the possessive (Marcones can be inferred to be possessive because plural doesn't make sense in context, but Nameless doesn't enjoy the same logic).  I got there in the end, but was quite confused for a while.

I'm not sure it could go to a jury trial.

Rudy is likely to admit to it to someone...

"Harry tried to kill me!"
"What? why? when?"
"He was acting shifty, I think he was involved with the blackout, I was trying to arrest him and Murphy came between us, she shouldn't have done that... Harry tried to pull something and my gun went off."
"You shot Harry?"
"No, Murphy, she shouldn't have come between us!"
"Okay, then what?"
"He looked at me, and I couldn't breath."
"Okay, then what?"
"That M.E. Butters came up with a flashlight and said something to Harry, Harry ground his teeth and then left."
"He just left?"
"Yeah, he did something and I couldn't breath and then after talking to the M.E. he just left, he tried to kill me!"
"He tried to choak you?" mimes hands on throat
"No, he walked up to me and I couldn't breath."
"He pushed you against the wall?"
"No... no, he didn't touch me..."
"Okay... you were trying to arrest him, on what charge?"
"He was just shady, I am sure he was involved in this whole blackout thing"
"What did you see that makes you think that?"
"He is always there in the middle of all this shady stuff, I know he was involved!"
"So you have busted him before?"
"Well no, Murphy always protected him before, but she can't protect him now."
"The same Murphy you shot?"
"Do I need a lawyer?"
"That might be a good idea..."

Toot unexpectedly does throw up pearls of wisdom and clarity of view look how he took Sanya to task for wrongly classifying him.

The first hurdle is swearing on the Bible, Toot is a creature of faerie and not the White God, so it is likely he would have to swear on a copy of the Pizza S’Press menu.

Toot wouldn't understand swearing to tell the truth...

Fae can't lie, but Toot can't even understand lying.

The Ladies in my view are meant to be the Knights director giving the Knights orders and information about when and where to strike. 
The Knights in my theory are meant to introduce new battle strategies and techniques. Teaching the armies that the Lady recruits how to use modern weapons.

I think it would be better to say that the Knights are 4-star generals to the Ladies President... or if you are British the ladies Prime Minister and the queen's well... queen...

The 4-star general plans the battle and directs the troops and makes the decisions while the president (prime minister) decides the objectives and goals and sets policy.
