"No," she said, answering his eyes. "I can never regret."[...]"I can sorrow," she offered gently, "but it's not the same thing." - Peter S. Beagle

…but to the unicorn’s eyes Molly was becoming a softer country, full of pools and caves, where old flowers came burning out of the ground. Under the dirt and indifference, she appeared only thirty-seven or thirty-eight years old - no older than Schmendrick, surely, despite the magician’s birthdayless face. Her rough hair bloomed, her skin quickened, and her voice was nearly as gentle to all things as it was when she spoke to the unicorn. The eyes would never be joyous, any more than they could ever turn green or blue, but they too had wakened in the earth. She walked eagerly into King Haggard’s realm on bare, blistered feet, and she sang often.
And far away on the other side of the unicorn, Schmendrick the Magician stalked in silence. His black cloak was sprouting holes, coming undone, and so was he. The rain that renewed Molly did not fall on him, and he seemed ever more parched and deserted, like the land itself. The unicorn could not heal him. A touch of her horn could have brought him back from death, but over despair she had no power, nor over magic that had come and gone.

Under the moon, the road that ran from the edge of her forest gleamed like water, but when she stepped out onto it, away from the trees, she felt how hard it was, and how long. She almost turned back then; but instead she took a deep breath of the woods air that still drifted to her, and held it in her mouth like a flower, as long as she could.

"It's a rare man who is taken for what he truly is," he said. "There is much misjudgment in the world. Now, I knew you for a unicorn when I first saw you, and I know that I am your friend. Yet you take me for a clown, or a clot, or a betrayer, and so I must be if you see me so. The magic on you is only magic and will vanish as soon as you are free, but the enchantment of error that you put on me I must wear forever in your eyes. We are not always what we seem, and hardly ever what we dream."
