Draco can feel the tension in the manor when she arrives. The elves are withdrawn and subdued. It is Malve's duty as Narcissa's bonded elf to perform the death rites. She takes great care to prepare the body in the funeral chamber. First, she washes her with herbs and scented oils. Then, she wraps her in linens of the finest quality. Once shrouded, Draco and Malve follow in procession to the crypt, where Malve lays the body in state.
As head of house, it then becomes Draco's duty to stand vigil. Malve leaves him after several hours, placing a preservation spell on the body and walking down the long cavern. Beneath flickering candles stands Draco. His hands rest on a cane, which is more for support in the latter hours of vigil than for any sort of show. His robes hang low over his eyes, disrupting his view of the body.
More than once, he looks up at her, only to look sharply away. He wipes away the stray tears that work their way out, but manages to withdraw his emotions for more physical concerns. By the time he hits twelve hours, his back is aching from the hard stone and his knees are beginning to burn. He's only halfway done.
Draco reverts to his childhood training of mind over matter and begins reciting the meanings of runes. After some time, he realizes this trivializes his vigil and is ashamed. Instead, he recalls memories of his mother. He remembers Narcissa reading to him as a child. He remembers her waiting for him on the platform after his first term at Hogwarts. Early Christmases. Gifts that were more than scholarly. Her reassurances during the war that she would love him no matter what he did—that even if he couldn't go through with it, she would be proud of him. Her soft smiles at dinner.
Before he realizes, Malve is walking back down the cavern to collect Draco. He collapses against her small frame and weeps aloud against her shoulder. She allows this, much as she did when he was a child. After several potions and some food, she encourages Draco back to the Manor for some sleep. The crypt will be sealed by Malve after Draco is seen to.
Draco crawls into bed, seeking the warmth and life of another—it is not his bed Harry wakes up, confused at feeling movement beside him. When he hears sobbing and a muffled, "She's really gone," he blinks his own strained eyes and holds the other man close. Together, their drained emotions fail to make some sort of sense out of the world. They fall asleep in each other's arms having shed much of the hatred and anguish.
In the morning, Harry wakes alone.
