Carnation
No matter how the story started, it ended the same way, but the red flower that bloomed through the cracks gave Hermes hope. Mortals said the red carnation was a symbol of poets and romantic love, and there was talk of workers using it to represent the will for change.
Hermes didn't put much stock into what most mortals thought, but he had to admit maybe they were on to something. Orpheus's song, even when incomplete, bloomed carnations from nothing, and Eurydice clung to his gift as long as she could before the wind tore it away.
And it wasn't just them; Hermes' mouth had hung open the first time Hades and Persephone's rekindled love had produced a flower from thin air. They danced with the carnation pinned to Hades' chest, and Hermes' heart ached when he thought about how maybe this time would be the one.
But even when Orpheus turned and the story reset, something else had changed beside the onset of spring. Eurydice found a carnation in her pocket, still blooming, and when she met Orpheus's eyes once more they glinted with faint recognition.
Hermes hoped the carnation and its promise of change would see them through to happiness.
