Clairvoyant
Narcissa was very into fortune telling's. She'd spend thousands of galleons on the best physics to be told of different futures and which path she should take and what she should do to live longer and be beautiful forever. Lucius, her husband, was never impressed with her obsession but she ignored his petulant rants of wasting his families' money and driving herself to her grave with this fake fortune telling.
Draco was a confused child because of his parents; his mother told him to believe anything and everything told by anyone clairvoyant. His father told him that it was all hog-wash and that, if anything, he should believe in your pride and nothing else. The young Malfoy heir, of course, followed his father's path. Malfoy did everything to show that his pride was number one, and nothing would change that – pride would triumph.
Narcissa stood over Draco's grave, holding a bouquet of white chrysanthemum's, orange lilies and one tiger lily. Lucius' grave sat next to Draco's, bare of any decoration other than the plain engraving of his name and the dates he had lived.
She told Draco, begged him, to believe the fortune telling of the wandering clairvoyant they met three years after Draco's seventh year at Hogwarts. Narcissa begged Draco not to leave on his trip to Canada – cried and argued with him that what the wandering physic said would come true. In the end he left, and here she was; alone and slowing dying in her loss. As she laid the flowers on her only sons' grave, she said only one thing before departing from the cemetery.
"I won't disgrace you by saying I told you so."
