To get back to the OP, we might think of some relatively new questions, but such issues will probably not have much meat on the bone.  In other words, they will probably be issues or ideas which have very little written in the books to go on.

For example, I've thought about Harry at the beginning of Skin Game, where he states that he has been thinking about his life, but what I mostly got out of that soliloquy was that Harry wondered who he could trust.  I imagine that was partly due to Nemesis; Harry can't risk openly discussing it with any of his friends, and partly due to neither Mab nor Molly answering his calls, but we later learn that Harry also felt he wasn't being visited very often by his friends. 

However, I would really like to know if Harry thought about anything else besides that.  I mean he had an entire year on the island.  He couldn't have spent the entire time learning how the island functioned and doing Parkour.  To get more specific, at the end of Cold Days Mab told Harry that the athame Lea received from Bianca was tainted and the infection spread from Lea to Meave.  In Ghost Story Lea told Harry's shade the reason she went gonzo on the Red Court was she owed them payback for the treacherous gift (meaning the athame) Bianca gave her.  Has Harry thought about this at all?  He knows or should remember that there were two powerful wizards (necromancers specifically) who were pretending to be Bianca's flunkies, dutifully retrieving and presenting Bianca's gifts.  Cowl and Kumori didn't contest this observation when Harry told them he recognized them from Bianca's party.  Cowl even played some one-upmanship on Harry by telling him that many things of consequence happened at that party that Harry wasn't aware of.

So we know Harry couldn't do any investigating while he was stuck on Demonreach, so there wasn't anything he could do concretely, but I hope in a future book this comes up, and hopefully it doesn't hit Harry out of the blue.  He's smart enough to have put the pieces together.  He should even be wondering how much his knowledge is worth.  I mean Lea would certainly be interested that other people besides Bianca were involved in giving her the tainted athame, and Harry knows that at least one of them (Cowl) is still alive.  Perhaps Mab would like some payback as well against a wizard or wizards who were instrumental in Maeves nemfection.  Without their specific identities Harry might not have enough information to make a deal, but he's an investigator, it's kind-of what he does.  So Harry should have thought about this topic and perhaps others while he was stuck on Demonreach Island. 

So we can talk about this and other things Harry might have mulled over, but I'm not sure there will be much textural evidence to backup any ideas we might come up with.

I don't doubt that he has thought about it, but he really doesn't have anyone to bounce these thoughts off of at this time now that Butters has Bob.  Bonny might know stuff but has zero experience in the world.  Murphy can help with her deductive cop reasoning but a lot of this is above her pay grade.

When is PT coming out?  Is there a release date set yet?

Not yet as far as I know..

What is frustrating is that it seems that there are as many loose ends created as are closed.  Although the reveal of Nemesis and ascension of Molly to WL, birth of Bonnie in SG, closed some loose ends.

To last few posters, I agree.  It's as if they must force water torture upon those that want a new book, because Jim feels water torture with the massive requests to hurry it along. So, they are willing to do the same thing to others that causes Jim pain.  Great move.

Worse yet, one gets the feeling that Jim may have more or less moved on... He has started another series, yeah I know he can walk and chew gum at the same time, but.....  So with personal appearances other projects and yeah the man is entitled to having a personal life, I get that....  The time stretches out into years between books...  Is it harder to come up with new stuff for a character he has been writing for 20 years perhaps, but then please end it skip to the BAT after Peace Talks..... Well, maybe do Mirror Mirror as well or many fans will burst a blood vessel if it is never written...

  Oh we few.... We faithful few....

I believe that the deal was contingent on power enough to beat Justin, not on his death. I would love to see Jim do another Ask me Anything Reddit so some longer form questions can be asked instead of the quick Q&A sessions at book signings. The nature of favors and power with regards to the Fae deserves a longer response.

Hasn't Jim also said that Lea didn't really give Harry anything in the bargain but a boost of confidence that he could kill Justin in a fight?  So it was a pretty dumb bargain on the part of a inexperienced sixteen year old.

For ex, the Council does recognize self-defense exceptions to the First Law.  Did she kill her rapists in the process of defending herself...or in revenge for the assault?  Did she use magic to try to defend herself...or did she go past self-defense into something else?

They do, but without a good advocate what chance does the accused really have?  When Harry was dragged before the Council to be judged, he was a scared kid with a hood over his head, they spoke in Latin, he didn't understand a word of it.  What chance did he really to defend himself if Eb hadn't come forth?   Given the recent history of the Council and the attitude of the Merlin, Hannah would have had no chance... And there is also this, how much knowledge of the Council and her rights did she have?   If she only had rumor to go by, of course she ran...  Harry was totally ignorant of both the Laws and the Council..  In my opinion if he had a clue at all he too would have ran.

Of course there's always the issue of whether she was believed or not, Harry was acting in self-defense but the truth of his claims were doubted.  But then again, Harry himself notes that Eb was not the only member of the Council who had sided with him, either.  How much of Harry's problem was Morgan's obsessions?

His problems with Morgan came later because he was of the same mind as the Merlin that potential warlocks once they've crossed the line cannot be reformed.  It is unclear how much they sided with Harry, they were mostly afraid of this kid with so much raw power that he could take out a former Warden in a duel.

Hannah's case is not necessarily a binary "Telling the truth or lying" thing.  She could be telling the truth and the matter still not be entirely as she describes it.  The more so with Lasciel whispering in her head...

Oh I think it can be the truth and exactly as she described it down to her bitterness after her friends died..  The question is more about what happened after that.   Here is my theory, Andriel sees and hears everything, so through him, Nic would be aware of Hannah and her plight.   Nic also knows that Lasciel was rejected by Harry and is none too happy about it.  So from there I don't think it would be too hard for him to arrange "contact" between Lasciel's coin and Hannah..  We know how good she is at twisting the mind, we saw what she was able to do as "Sheila" to Harry in Dead Beat, only he was saved by Butters pointing out there was no Sheila.  He was saved by that and the fact he had had an earlier soul gaze with a Denarian in Death Masks and didn't want any part of that club.  So it isn't too hard to believe Lasciel could manipulate someone already angry and very bitter with promises of revenge for her friends.

Haha no, I was working from memory and forgot her last name lol.


Hannah had the Coin for a while I think.  The fireball that she had incredible control over killing the Fomor goons needed incredible control, and I believe Jim said that Lasciel was what gave her that precision.

All that says is she had the Coin post Changes...  So she still could be telling the truth..

Opportunities work best when you know when they are coming.

 Do they?  I think it is more the law of unexpected and unintentional consequences...
