Jonas,
Are you saying that when Molly was take to AT in DB, she was forced into playing the part of a queen? Like a foreshadowing of her taking on the Lady's reigns?
Entirely possible, if you mean PG, not DB
I try to keep idea's pared down to one topic/theory at a time, but a lot of my theories start to interconnect and be dependent on one another. I find it becomes more palatable that way. Here is one that backs it though, i'll try to point out assumptions made from other idea's.
The BC connections/hidden baddie basically gives Molly the idea to use magic to cause fear. Using the forces of creation to do so. The direct result from the 'good guys' side is to kidnap and feed upon said person, intentions be damned that's what they did. They ate pieces of her life force, digging into her soul a bit like happened to her brother.
Directly after that we get the knowing look from Scarecrow(Which iirc the Loup gives Harry too? Idk, somebody shares that look/description) followed by a speech saying more or less he's from beyond human memory... He should be in oblivion!?
*I love the whole batman, sleepy hallow thing going on in PG btw
So fast forward to some future events, Lea is training Molly how to use fear as a weapon without violating Council Laws, using grey area's that don't take away choice. Later on an outsider called Fearbringer in truth is born into the world and Molly ends up WL in the same book.
Those events are directly related, despite what Mab might 'think', Lea was always training Molly into the Winter side. It's all she knows and the 'mirror' that drew in the WL mantle. Something explained in a 'slight of hand' in PG on how spirits find beacons in the mortal world to come through. This is how the Ladies mantles find hosts and how N and company find things to influence.
Tangent:N gets influence into mortals but mortals change so it's not such a threat, but Wizards can also birth things into their thoughts, literally becoming more of such a thing by using their magic that way. So if their using magic that doesn't align with reality, that makes them more of a mirror for an outside presence then a slow possession takes grip. Where in the end it's not so much they took control, as they became them in truth. Hence Warlocks are born, and Wardens who trap outsiders get repurposed with killing deranged magic users.
They're one and the same thing. They just didn't get born with all their horrible power at start (this is also why I say Naagloshi and those who walk the path of a Naagloshi are the same thing).
Now, where was I... Ok, so Molly was a beacon for fearbringer but the Fetches ate the Nfection out of her, this is why fearbringers functionality is based on the scarecrows body type. He's an amalgamation of all the fear Mollys identity/soul caused. He gets a cloth shroud because Molly's been leaving Harry's death shroud, that which he was last seen wearing before death, at the scenes of her fear inspiring deaths. SHE'S molding how fearbringer is shaped.
She's the new version of whom made the Mantle of Mab, the starborn of THAT star. Which is not a common idea behind starborn, I know) But what if these millions of starborn are just incarnations of specific stars and the reason why none of them do as much as Dresden is the same reason Mortals aren't as susceptible to N, they don't have the power to birth much of their original mold, for lack of a better word, into the world. Instead of all these mantles being simply broken down graces, they are fragmented portions of the same cosmic identity. Leading to characters/ immortal incarnations with very similar stories and abilities. GK domain is moon, stars farther, outside. All the Greco-Roman gods were planets in our system, so not so much 'star'born as 'celestial body born'?
So Mab's origin is as Fearbringer, Molly's the newest incarnation. That they were trying to use to displace Mab's power and they wanted to become Mab's power(which again, Mab could even
thinkMolly's more suited to Summer while knowingly prepping her winter, to show yet another foil)
Oh yea, ok so. When PG was going down Molly was already exhibiting traits of being a Winter Queen. I feel their overall goal was to corrupt not only a potential bearer of WL or Q, but to try to bogart that power like the LoONs did and influence how the WQ power was distributed in reality. That the consciousness the power of the entire courts was separated from on the stone table would again have hold. FB has the same 'power' as Mab but is 'deeper' in a necromantic sense. Older.
Mab's precise reasoning depends on the order of events at AT, but I see it close to this. Mab on the other hand may have known she would be the most precise reflection of WQ besides the Lady so had to bind her with the fetches before she could leave, leaving an Nfected mortal WQ or L behind(depends on where the Mauve situation was in linear time, hard to say). Weakened, unconscious, being fed upon, even if N managed to take root there wouldn't be any power to act. So Mab was covering her rear and siphoning off Nfection of a major player in the future of the power behind the Queens.
Leaving off a whole other tangential theory on Who the courts were made from, what they represent in the DF, their previous role in reality, ect. It would take a lot of space and expo. I will say, in SK the color of horse that the Lady/Queens were on was the start of that.
Questions?
