Oh I don't know, it's always possible, not every wizard is financially smart.  Harry isn't and up until the end of Battle Ground he was a member of the White Council.  Now he might inherit from Eb, but at least on the surface he doesn't appear to be financially rich either.

Yeah, Harry isn't very smart that way... but Jim has said more than once that the WC "financial wizards" are producing a LOT of wealth, and that individual wizards of the Council often invest a bunch of money with the WC investment arm.

It's just that Harry's actively stupid about money... "sockfull of diamonds" should have gone 90% to WC investments; hell, to *any* investments!

He could literally have lived off the interest for the rest of his life... tho expensive projects (like Svartalven items) might need him to dip into principal.

And of course, the whole "Castle Upkeep, taxes, etc" issue is just fantastically expensive, not even "sockfull of diamonds" carries that very far!  TBH, I'm not sure Jim thought through those "castle consequences" properly...

This is about the only thing I dislike about the Dresden files books.  After the first 6 books explained the "Blue Beetle" to us over and over and over I was like "Yeah Jim, I already freakin know this....."   If someone starts reading a book series at the end they deserve to be lost and not clued into the small details..

I think the conventional wisdom is that writers of long series should do this; it's not unique to the DF, there's lots of longer series that recap old info for new readers.

Will she? 

I'm pretty sure she would... if they'd accept a weregild instead of blood (which I think a very chancy bet).

It's only money, which I think
 (a) the Whamps don't really value that much (it's just a mortal-centric scorekeeping device)
and
 (b) Lara is in control of the decision, and repeatedly goes to great lengths for Thomas

This, so who is going to pay it?  The White Court, since Thomas is a vampire, or the White Council because Thomas is the half brother of a then White Council member, Harry and the grandson of Eb who not only is a member of the White Council, but a sitting member of the Senior Council.. Even if Eb claims he didn't know, would they believe him? 

The Whamps (specifically, Lara) would pay it.
The White Council would not -- Thomas is a Vamp, it's Vamp-business.
I suspect Eb hates the very idea of Thomas existing, and would just as soon the Svartalven vengeance erased that blot on the McCoy family honor.
 

We will find out more about what a STARBORN means in chapter one of MM.
Jim also said that the fandom SHOULD be asking why people don't mention the outsiders more. Interesting! 

YeahNO, pretty sure the fandom has been asking!
Jim just gets squirrely, and gives one of his stock non-answers.
 

... Maybe it was awkwardly done to inform new readers ...

This, I think.
Jim usually includes some new-to-Dresden exposition in every book, and this seems like an example.

I read the Amazon early-release chapters, don't have book in hand yet.  But I kinda-sorta thought Lara was trying to elicit Harry to talk more, in hopes of gaining more insight.

Insight about Harry.

Insight about Soulgazes in general:  her just knowing they exist, 'gazing on Carlos... these hardly make her an expert!

Also, plenty of people will play the "novice" card -- when they aren't -- for a plethora of reasons.

I don't remember it being said.  Nor actually do I remember Harry ever allowing Mister in his lab where his circle is located.  Or rather I don't remember Mister being in the lab at anytime...

No, at least once Harry *intentionally* set Mister to mayhem in his lab:  the oakleaf lure in Little Chicago!

There is a WoJ on this that I believe was something along Thomas wasn't planned and he was the result of all the awesome vampire sex.

I recall this WoJ too.  Wasn't planned, was very unexpected -- whampire-babies don't often carry to term.
