Merlin... What's happened to her?
She's gravely ill. Do something! If I could... Please, Gaius. Merlin, this is no ordinary illness. This cannot happen! Who did you meet at the isle of the blessed? Nimueh. Nimueh? It was as you said. She demanded a price. But I bargained my life, not my mother's! Merlin, I wish there was something I could do. I will make you better. I will. You knew this would happen! You had me trade my mother's life for Arthur's! You said you would do anything. Did you know my mother would die? I knew the price would be a heavy one. But you sent me anyway. We need Arthur to live. I'm not one of you. We are both creatures of the old religion. It is the source of you power.
