And even as she watched, she saw the prism fill with glimmering silvery light, and a soft voice of singing, and the sadness in Sam's eyes began to dissipate little by little, until a golden glow like candlelight illuminated him and he looked to be listening to words she could not hear. Before long, a happy smile found its way to his features, and she knew that her work here was done.

Farewell, friend, she whispered as she diminished to a tiny bubble of light that Sam did not see.
