Snape stood before the cabinet, waiting. His wand was drawn and his heart pounding. Moistness glazed his brow. The doors flew open, then she appeared, red-haired, slender and pale, her familiar green eyes glacial. Her moist red lips parted as she approached him.
"You were never worthy of me, Severus. Never," she said softly. "Why I was your friend I'll never know."
Snape stared at her, ache and anguish in his heart at seeing her again.
"Riddikulus!" he hissed, blasting the Boggart back into the cabinet.
"You were never my friend, Lily Evans. You were my obsession and my curse."
