Comment on Justine is not known to me.  Where do we get the hint that Justine has some hidden background?   Not surprised, just not familiar with the details.

I don't have the source anymore, just going off a vague recollection. Might have been one of the AMA's, but I'm not positive.

The WOJ itself wasn't super specific. The gist was just that there's something about Justine's parentage that Harry doesn't know but Thomas does - it didn't narrow down whether she was a changeling or her parents were some sort of VIP's in mortal society or something else entirely.

And that none of the other people in the building managed to kill some of them too.

Even if the rest of the FBI were too shocked to line up a headshot or hit the kill spot on the belly, just wounding one heavily enough to leave a bloodstain would be evidence. Forensics is going to be very interested in a DNA profile on any 'terrorists' that escaped with wounds after something like that.

The more we dig into this, the more I think Jim is going to have to include some explanation of the aftermath of that as Harry reestablishes himself in Chicago. Shit pretty much had to have hit the fan after that incident - it's one thing for him to have been out of the loop during past events, but once he's back on the grid, there's going to have to have been some fallout that comes to his attention.

Well, Harry is an example where it breaks down then, because he didn't get one, right?

I thought the implication there is that some level of fencing instruction is part of the general Council apprentice curriculum, though I'm not sure I agree. Nobody seems to have been after Harry to teach Molly to fence, for one thing. And we don't know where or when Harry studied fencing to get to his stated description of OK at it but nowhere near good enough to challenge the serious swordsmen. There's never been a mention of whether Justin taught him that, Ebenezar did, or he decided some lessons after leaving Eb would be a useful skill.

In terms of a weapon though, I really can't see Dresden taking up Amoracchius at this point after all the buildup that it has to be meant for someone with the right biblical virtues, even without the WOJ that a sword for Harry isn't in the plan. The Warden of Demonreach has to walk in a lot of grey areas, whereas the Swords are for paladins, pure of heart.

If he's going to get any sort of special weapon, my money is on figuring out how the four of five artifacts from Hades' vault that he already has actually work. Many have speculated the 'knife' might be the head of the Spear of Destiny - if so, the foreshadowing of that being mounted on his staff is, uh, pretty strong. How cool would a showdown between Harry and Cristos be, with Cristos expecting the sword he kept as a former warden to undo Harry's staff, only for Harry to break his sword instead when they come to blows?

Maybe one is sick or has an unusual relative. 
Alternately, Harry can identify one of his companions as nemfected, with obvious implications. 

Like what the 'something significant about Justine's background that Thomas knows but Harry doesn't' actually is.

Though with divergent histories, it's possible for someone to be N-fected in one universe but not the other.

He told /An Agent/, but I dont know that the FBI as a whole was made aware of the fact in any official way (even an ignored one like with Butters and the CPD).

Yeah, Tilly got clued in, but he can't very well report everything he knows up the chain without getting fitted for a straightjacket.

On the other hand, Harry and the gang dropped some bodies at the scene, and as I recall Murphy mentioned killing another set to guard the stairwell after they split up. If the Eebs missed removing any of their dead, inhuman bodies left behind after massacring a bunch of federal agents would be orders of magnitude harder to make go away than one videotape of a loup garou.

Only instead of Intpol, the Librarians.  Favors exchanged between the council and the LoC could work this way.

Pretty sure the Librarians would be just about as averse to the White Council learning about their organization as just about any of the other supernatural nations. The WOJ about them was that they're obsessively secretive out of caution about the powers they're in opposition to. I wouldn't be surprised if they were behind a few of the assassination attempts against Harry that haven't been otherwise attributed (though Ace is also a candidate).

There is no blade that can pass through a coin, it would hit the coin, and deflect a little bit to pass through the skin next to the coin.

Well ... the faithsaber just possibly might. And we don't have a clue of the abilities of the knife (spearpoint?) from Hades' vault yet.

But from Harry's description of their auras, both of those are vastly more powerful than even Medea's bodkin.

Successful rulers and leaders often are not.  Sometimes you can't be both nice and successful in politics and war.  It's not hard to find examples in history of kings and rulers who were kind, decent...and ineffectual or worse.

In-universe, Nic even acknowledged at one point that Marcone would have been a successful ruler in times gone by.

Am I going to have to get this one? The title seemed silly enough to put me off.
