I dont recall hearing that theory before, but you know I think I really like it! Id been associated the metal teeth with her identity as Baba Yaga, who is also known as Old Iron Teeth, but I never had an explanation for the others
One looked simple enough, all white and even. Death?
The next was rotted-looking, with chipped incisors and a broken molar. Famine?
The next set had all pointed teeth, stained with bits of rusty brown and what looked like rotten bits of flesh stuck between them. Pestilence?
The last was made out of some kind of silvery metal, shining like a sword. War?
I think.. The clean ones are famine, cause they've never been used, The decayed ones pestilence/disease, the Fleshy ones are actually death which i'll get back to, and the last is of course war.
Why is death the flesh ridden ones though? Because death consumes, as Baba Yaga, She's known for eating things she catches. Those iron ones Might be hers as death incarnate but not necessarily as the Horseman's death.(I actually think she's best described as the Apocalypse or the End, which *cough* death follows after..)
This actually ties to a whole host of other theories I have... because of course I think it's all connected. But ye gads... if you wanna hear that one let me know cause i'm seeing three way different topical paragraphs swimming around on that one...
Ah, I get it you are talking about the Loom and Spinning wheel mentioned in the corner of the Cottage in SK. We've only had the two visits to the Cottage and the majority of the miscellany of the place was not described in the second visit. But given that the second visit /did/ serve to confirm that the Mothers are in fact also the Morai (or part of them) which directly ties them to said Loom and Spinning wheel, I wouldnt go so far as to call it regret on Jims part or a reversal. Just lean scene description?
...Make that 4 lol. Well see I think the things shown in the cottage are things intentionally taken out of play.(five dammit!) Out of the balance as they have no place in it. The loom belongs to the middle one, which is 'missing', but whose aspects can readily be found in the balance of the fairy courts themselves. I think the objects represent mantles of authority sans the identity attached. All those roles represent things that make choices for mortals, by killing them and dictating the end, or simply weaving their lives as you see fit. So we have The Clotho the spinner of life and Atropos, the cutter with those Shears(Mentioned in a woj about why all obey the mothers) which Harry names MW directly. But Lachesis, the chooser, the 'dispenser' of fate isn't around, and that's the Loom she would weave from.
So the Sidhe got, 'keepers of the balance' and Mab got 'Judgement' aspects but not the 'choosers of fate' one.
*List them paragraph's real quick Courts, walkers, knights, table, magic, aura's... damn.
