Hmm I kinda think Battle Grounds ws the last sentence of the WOJ...
Battle Ground was the Battle Royal.

Battle Ground was not the Battle Royal.  You had a frickin' Titan walk up and go toe to toe with a bunch of the big powers of the accords.  but... how many of them died?  Sure Titania got smacked around, still here.  Odin, still here.  Heck even the white court, the wizards, the knights of the cross, and Marcone are all still here.  Sure, in another place we lost some wizards to an opportunistic Drakul and had a mortal kill a mortal, but in the big throw down?  Not a single important opponent of hers was killed.  Seems weird for such a dangerous situation unless it was all planned out ahead of time to at least some degree. 

It's been discussed before that using soulfire in the making of a magic object (like a wizards staff) is dangerous because then there is something out there that may actually work as a direct connection to you/your soul thaumaturgically.  But then on the flip side we hear that all the active einherjar are actually some form of necromancy combined with soulfire, which would seem to bear the same risk (if you're ballsy enough to try to make a thaumaturgical link with Odin).  So I've still been thinking about soulfire uses, and had one thought on a side effect.

1.  Wondered if it would work to imbue Harry's new home with soulfire as he reactivates the magic.  Bob once described it as using rebar in concrete to make the whole stronger than the sum of its parts.  It seems like buffing up your home defenses would be a great place to use it, and reasonably safe as well assuming the home defenses are significant enough.  I would love to see someone really lay siege to his castle sometime and see it just hold everything off thanks to soulfire being built in.

2.  Harry made the bear belt buckle that literally held magic/mana in it.  Wonder if he could make something similar to hold soulfire.  Probably would not be worth making considering the fear of losing it... but just wondering what could be done with it!

Then I had my side thought: Home is where the heart is.  Home is part of you, and the more it is really part of you, the more you are invested in it, the more of yourself you put into it, the stronger the threshold.  what if the threshold effect of homes is really a soulfire kind of effect?  Not everyone uses magic, but everyone has souls.  I wonder if homes of things without souls have thresholds?  That would ruin that idea, but I think it worth discussing.

So I'm watching this interview again, and the podcasters asked about when we'd see Thomas again.  They all want to know when they'd see him again, because the feared missing him.  JB's reply was "you could say he hasn't grown very much".  Perhaps Demonreach is the Chrysalis and Thomas is the soon to be more powerfull butterfly.

Makes me wonder if being faced with all the badness he has ever done and then being given time to reflect on it, and possibly to confront his Demon might give him greater control.  We know the Demon can feed on any emotion - different houses just choose to specialize in different emotions - pain, fear, and lust.  What if he were to... recalibrate to Hope or Love.  Would he be able to feed from the angel within a holy sword of that type?  Imagine a white court vampire fed by an angel wielding a holy sword...

I just realized a problem with Battle Ground - the Huntsmen, non mortal fomor, killed 95% of the people in the neighborhoods they went through.  This is after Mab told all of Chicago to essentially stay inside for safety.  What happened to their thresholds?  Seems like Jim just forgot about them.

I might be missing something, but is there any reason the Genoskwa can't just open a portal out of the never never back into our world?

Yes, the underworld has barriers.  The only place that could be gated to from the vaults was the place at the beginning of the challenges - where they came in.  That's why they all had to run back there and hold the bank while they were inside, instead of just going in there, doing the heist, and existing from inside the vault itself.

It is worth realizing the if functional the Genoskwa could probably open a gate, so escape isn't 100% impossible but honestly it just seems really unlikely and against the story there.  That means there's something special about the Genoskwa being back - and I think it has to do with Nic hiding.

Will be interesting to see what a sword like Butter's can do to a white court vampire.  Can it kill just the demon?  Same question with Justine - could it just kill/drive out Nemesis?

I think it is clear that this obligation will extend to winter as long as he is their knight, so even if something does happen to him, winter would be on the hook to pay these debts - just look at the debts winter handled while he was "gone" like with the guard. 

I think this will extend is "power" through providing him with some authority/trust with the people of Chicago.  As his knights call in their debts it will become known that:
1.  He pays his debts
2.  He's around to help Chicago

Harry talked like he wanted to start an organization in Chicago, potentially of a scope to rival Marcone's.  He has the BFS, the paranet, and his knights to start with.  I think the maintaining of this connection with these people, these people who are willing to fight for Chicago and who have followed him before, is definitely him extending his authority and laying the groundwork for his new organization, including the debt a leader has to his followers...

Harry thinks in Peace Talks as he is getting the Knife from Alfred, If it truly was what I was pretty sure it was, then using it was going to put me in a long-term pickle"

You'll note he actually never has to use the knife as a knife in Battle Ground.  Jim conveniently finds a work around and has Marcone provide him with a bloody knife.  Harry uses the knife as an Anthame in the ritual, but he never uses it as a weapon.  I don't think using it as an Anthame, "put him in a pickle" so to speak, so I suspect the consequences of actually using the knife as a weapon are still to be revealed and are more in keeping with stories of the spear of Longinus.
