"What does he remind you of?" Ask anyone, and they'll answer the same. "Fire."
"What does he remind you of?" Ask her, and she'll answer differently. "Smoke."
"What does she remind you of?" Ask anyone, and they'll answer the same. "A doll."
"What does she remind you of?" Ask him, and he'll answer differently. "A witch."
Fire takes anything in its path (and the smoke takes anything that remains). Dolls captivate people with their beauty (and witches captivate those not lured by appearance). Both are pretty in their own right (yet they make you think of something so ugly). It would only make sense that putting them together would create something of unfathomable beauty (but it would leave behind something blindingly disgusting). Him, with his vibrant (bloody) red hair and his intense (acidic) green eyes. Her, with her flaxen (fool's gold) hair and her enchanting (haunting) blue eyes.
Red and yellow make orange (blood is shed for the witch's illusions of fool's gold).
Green and blue make turquoise (the smoke's acidic taste is still haunting).
Put fire to a doll and it will burn (put smoke to a witch and she will suffocate). He knew this (and it's why he got close to her in the first place). She didn't (and it's why she lured him in). The sight of burning, combining two such unique spectacles; it was gorgeous. But ultimately only one thing was left over. The fire, without something to burn, flickers out of existence and nothing remains (the smoke is all inhaled and nothing remains). A doll burns and leaves ash (a witch dies and leaves ash).
And when it was over and done with, that's all that they were.
Taken by his own element, fire, he faded into nothing (just as smoke does when the fire goes out).
Her deceit backfired, and disintegrating like an old doll, she turned into ash (just as the witch does when her spell is turned back on her).
But was it really fire that took him (was it not the scheme of the witch)?
Was her frailty and failed plan really her downfall (or was it the smoke that had lingered)?
It was all her fault. He had fallen for the doll (and he'd been captivated by the witch).
It was all his fault. She had been entranced by the fire (and she'd been suffocated by the smoke).
In the end, they had both burned.
And ash and nothingness was all that remained.
