Harry the unreliable narrator with a very confusing backstory even without the constant shifts?

Is he?  Everyone says that yet outside of a few short stories he is the only narrator we've got. So is he a liar? Just stupid? Maybe senile when he wrote his story?  Unless you got an alternative story out there..

Let's jump back to Star wars for the metaphor of chosen Orphan. Did luke know... Anything that was true? Leia what about Rey?

What has that to do with anything?  Harry is a starborn, he would be so whether he was an orphan or not.  As far as his names go as Harry explains back in Fool Moon, it isn't the names themselves that would give Chauncy power over him, it is giving him, his names..  Harry was careful even to change the inflection of how to say the names he did give him to try and prevent Chauncy from having power over him..  Didn't matter if his name was John Jinglehimer Smith, or Harry David Copperfield Dresden, it was giving his name or part of his name that gave Chauncy power over him and what he bargained for.

I find it far more likely they named him together, as they were indeed together before her death 👀

So what if they did? Harry's name in of itself has no power, at least up to this point it hasn't shown itself to have power of any kind or protection.

I find it fair less likely Malcolm named him unilaterally and just by happenstance gave him the extra protection of names in a verse where such things actually matter.(Something Harry mentioned in storm front, FM, GP, ECT)

Whether Malcolm did or didn't give him those names unilaterally doesn't matter.  The name, Harry, in of itself has no power or protection, nor David, nor Copperfield, nor Dresden, what gives power is that they are his names.

Again:  do we know this?  Was he on-board with the "starborn" scheme?  I don't really count the scene in the dream (around the campfire), because it's evident that Malcolm was VERY clued-in at that point.

Oh I think he was more clued in than you think, at least the importance of the conception, even if he didn't fully understand.  This is hinted at both by Margaret herself during Harry's soul gaze with Thomas in Blood Rites and when Lash begins to tell him about his power over Outsiders in White Night.  It takes two to make a baby, and that's even more important in the case of a star born.

  I realize we are going far afield again, but I guess it is all related and there are so few of us now posting.
Anyway....

The DF Wiki says so, too:
Quote

    The tradition of the White Court is to not tell a young potential succubus what they will become, or even anything about the supernatural world. In their childhood and early teens they are raised as a vanilla human. Their first feeding, which is always fatal, comes as a surprise to them, and introduces them into the world of the White Court.

(footnoting this factoid to White Night ch.27; I have not gone back to find the original passage(s) supporting this.)

I just did go back to Chapter 27 of White Night, other than stating that Thomas was hungry and that he tries not to kill, nothing about what the DF Wiki sights.. However in Blood Rites there is, it talks about if Inari is in love she might be able to avoid that first feeding. Even if she cannot avoid it, if she and the young man love one another the Hunger Demon could be killed.
Blood Rites 164-165

page 164, Thomas leaned up against the wall beside my mother's portrait.  He pushed his hair back from his face with one hand.  "She hasn't been taken by her Hunger yet," he said.  "Once she starts feeding it there's no going back.  She'll be like us for the rest of us.  My father is pushing her toward that point.  I want to stop him."
"Why?"
"Because if. . .if she's in love, that first time, it could kill her Hunger.  She'd be free.  I think she is mature enough to be capable of that love now. There's a young man she's all twitterpated about."

That indicates there is a choice if the would be White Court vamp knows before hand.  The reason why the set up for Inari's first feed to be on Harry, she isn't in love with him.. She'd kill him, be hooked.  Also note that timing is important, Thomas states that he thinks Inari is mature enough to experience true love.. So Raith has to set up his daughters before they have a chance to be in love.
page 165
 

Thomas pressed his lips together for a moment and then said.  "If the kid loves her in return, then she could have a life.  She could be free of the kinds of things that---"  His voice broke.  He had to cough before he continued."Things like what happened to Justine.  Like what my father has done to my other sisters."
"What do you mean, done to them?"
"He establishes that he is their superior,  He overpowers them.  Pits his Hunger against theirs."
My stomach twisted.  "You mean he feeds on his own. . ." I couldn't finish the sentence.

So the above establishes a couple of things, 1] once the feeding begins, the would be vampire is toast, a vampire. 2] True love can kill it at this time.  3] Raith did set up his daughters so they had no choice upon whom that first feeding began, so it happened and results in death of the victim. 4] Most importantly Raith sets them up so then he can establish Hunger power over them though incest.  No, I don't think this is standard White Court practice.

This is pretty much "family life" for all Whampires.

The parents all "set up" their kids, try to make sure that "first feeding" is just teen hormones & body-chemistry (or teenage angst/despair for the Skavis, etc).  A few train them young and ruthless, so they know ahead of time... but that's the exception.

I don't think so, the impression I got from both Lara and Thomas that at puberty it is about choices and there is a more natural process for it.  That's why both of them wanted their little sister away from their father.  Inari still most likely will fail at true love, Jim left that an open question as far as her future was concerned, but it would still be on her own terms.  I think the point of both Thomas and Lara were making was the way their father pushed and tricked them into that first kill was to gain control and power over them, and they didn't want that for their little sister.

I think it's worth noting that there are two questions being addressed in the thread:
1st (as posed in this OP) - Is "Karma" a bitch?  Does "Fate" now have a violent end in store for Thomas?  Is Thomas (having murdered) now doomed to face a violent (albeit possibly heroic) end?  It's worth noting here that Thomas has been a murderer ever since we met him:  whampires only manifest fully after their 1st full
 feeding, which AFAIK is always to the death (n.b. Connie & Irwin are an odd case)... so Thomas must have killed his first lover.

Yes, he did murder his first victim, it has been years since I read Blood Rites, but if I remember correctly Lord Raith set him up. Young, with perhaps little understanding of what he was, let alone control, he fed upon his first victim until she died and became a full vampire himself.  Lord Raith did the same with Lara, and tried to set up their little sister, Inari with Harry as her first kill.  Interesting that though especially Lara was at peace with her status, Thomas also for the most part, neither wanted that for their little sister, they wanted her to have at least a choice, nor have a chance that true love would burn out the Hunger Demon before she killed anyone.  In short Lord Raith set Thomas up to commit murder, and in spite of some efforts not to, he has committed murder since in the course of feeding, especially during and after the Skin Walker had a hold of him.

Well, Lea can.  Doubt it's a general thing that very many of the Fae can do!  I bet Mab can, and maybe Titania.  I doubt the Winter Ladies could do it:  Maeve was too much of a slacker, Molly is both too new, and likely still flinches every time she thinks deeply about Rampires.  I'm less clear about the Summer Ladies, but kind of doubt it:  Winter (as led by Mab) seems to embrace the "knowledge is power" trope more; Summer seems to more intuitively feel that knowledge flows from power.

Also, Lea talked about it as a secret, as knowledge that she could trade for; not an inherently "faerie" power.

I think both Courts can do it, I don't buy that the Fae of Summer are less powerful than the Fae of Winter.  We have seen both Queens in action in Battle Ground, they seem pretty equal to me.  So while they can put the vamp part to sleep, it doesn't mean they can do it permanently.  Yeah, well, Lea was trying to make a sale or what she'd call a bargain.  The Fae are very good at the con game, while they cannot lie, they are not totally honest either.  What they do is push just enough truth, i.e. Lea said she'd trade for the knowledge, which she is vague about, but at the same time not lying about, in the hopes that Harry would be so desperate for a cure that he'd lie to himself about what it was exactly, that she was trading, and make a bargain for it.. 

Not sure if anyone not in love is immune

  Well, it is complicated, because being in love doesn't always mean true love.  Falling in love can be merely the emotion and or sexual attraction of the moment, where as true love is something deeper and not easily undone.. Which is another glitch in the system if you will, how easily the true love protection is wiped out by a simple sexual transgression..  In other words, a person can be truly in love with someone, have a one night stand that is purely physical with someone else, remain truly in love with that original someone, but because of that one night stand lose their protection.

The "legalities" within Faerie are quite absolute.
Legally-outmaneuver a faerie and they will do something they absolutely HATE having to do.

And the Kringlemantle is Fae.
Kringle thus has to obey Mab.
Odin does not have to obey her... Odin seems able to put on & take off the Kringlemantle at will (tricky sort, Odin; just as much so as Mab, really).

Notice that Kringle uses the word "protocol"  As defined;

What's the difference between protocol and etiquette?
Is Etiquette the Same as Manners? What about Protocol and ...
While Etiquette & Manners involve the rules of politeness and compassion among people in a social setting, Protocol comprises the set of rules associated with formalities, ceremonial events and official occasions involving nations and their representatives; as well as functions or formal procedures related to ...

Kringle doesn't use the word mantle anywhere when he describes himself.. Nor does he mention putting on or taking off a mantle.. 

Legally speaking, Kringle and Vadderung are two entirely different people who simply happen to reside in the same body," he replied

So no, I don't think Kringle is a Fae. Just a guess, but I think under the Accords protocol, Odin as Kringle is a member of the
Winter Court.  He does have to obey certain rules under protocol, but I doubt that Mab under those same protocols can
force Kringle to do anything, nor can Kringle do what he wants.. As Kringle explains...

    "That's just a fiction,"I said, " a little game of protocol."
    ""Little games of protocol are how one shows respect, especially to those with whom one does not get along famously well.  It can be tedious but generally is less trouble than a duel would be."

I don't think that the Hunger Demon is much like a mantle, though.  Obviously, Jim could write that it is, but they seem entirely-separate things, to me.

  The Hunger Demon is nothing like a mantle.  The Hunger Demon is more like a parasite that the host is born with.  When the host reaches puberty or sexual maturity the HD parasite is ready to feed and awakens with the first sexual experience and full maturity when the host feeds on the emotions of the victim until it dies.  It is a symbiotic relationship, it compels the host to feed,thus flourishing it and in return it gives the host, youth, exceptional strength, and beauty.   

"Claus" is specifically the Kringlemantle, though.  Mantles are constructs, and made to be separated from the people who wield/wear the mantle.  Odin, in particular, often takes off the Kringlemantle (I would allege that he is only rarely Kringle:  because Kringle is subject to Mab, but Vadderung & Odin emphatically are not).

I don't think Kringle is subject to anyone, I think Kringle is merely another aspect of Odin's mantle.

I don't think we've ever seen the Mother/Queen/Lady (or Knight) mantles separate from their owners (except of course when the owners die).  Vadderung has told Harry several times about not always being Kringle; I expect this foreshadows Harry being able to "take off" the Knightmantle, and put it back on.

Kringle also told Harry on Halloween during "the Hunt" many mantles/faces maybe worn.  Odin is a god, where as Harry is a mere human, wizard, yes, but human, I don't think he can take the Winter Knight's mantle on and off like a cloak.
