"It feels right," she said, voice taught as finished the cut, "to commit my body to flame. Because while I am part of the Supernal, Daisy is not. So, born of the Lie she dies in the Lie. Is consumed in the Lie. Yet, the lie is shaped by the Supernal, and the fire is the symbol of the Crucible that will refine Daisy, and the Lie, into the Supernal. Into...me."
A thought process most would misunderstand, and consider one of her petty tyrannies. Yet it was her mind, her substance that was changing, and it was her mind that would do so. This action, even if rooted in a leap of imagination rather than logic, still held true to herself, the self much larger than the portion which bore a name, and through that she would approach a new Wisdom.
Except...her self wanted to acknowledge that this came about not just from something born from her own mind, conceived in some petty act, but instead born from the mingling of the influence of another. From the interactions with the other that continually informed the self, and through the self, informed the other.
