Stupefy!
His spell misses, and hits a nearby wall. Now he can see the young Auror getting up from her crouched on elbows position, her bubble gum pink hair turning slowly to a mousy brown, her eyes turning from a vivid violet to liquid cocoa.
Like her eyes...
He has never quite gotten over his heartbreak, her harshly snapped words in the privacy of the Forbidden Forest. He loves Narcissa as much, if not more, than he once loved her.
Once. Loved. But not any more.
He sometimes, seldom, rarely wonders about what happened to the disowned Andromeda Black. Now he knows.
Her hair is certainly not as nice as a colour as her mother's, but it's wavy, in contrast to the curls she has always hated for making her resemble Bellatrix. Her eyes, in contrast, are rightly the same, sweet goodness and all, but they are hateful at this moment, blazing, narrowed-eyes mad. She advances, wand gripped tightly in her hand. "Kill me, then, Malfoy," she shots defiantly. "Or are you too much of a coward to do so?"
"I don't hurt children," he states back flatly.
"You don't hurt children," she repeates slowly. "I'll eat my hat, you're a bloody Death Eater for goodness's sake!"
"I think you are just angry, girl," he says coolly, "that I consider yours truly a woefully incompetent child."
She is not yet giving to her Black blood coursing through her veins. She glares at him all the same, her hair turning tomato red and her eyes flashing with a glint of scarlet. "Like how you would not hesitate to kill a child, such as Harry and his lot?"
He licks his lips, conscious that he must think carefully for this one. "It was never my intention to fatally wound Potter or his friends," he says finally. "That was always Bellatrix and the Dark Lord's job, not mine. My job is to retrieve the prophecy, and it has smashed, so now my aim is to escape. You are merely an obstacle."
"An obstacle!" she snorts. "Well, I will stay one." She points her wand at him. "Sectumsempra!"
"Protego!"
The force of his shield knocks her backwards, and he is tempted to help her get up, but represses the urge. Bellatrix is right, the Dark Lord always knows and will always know.
"Leave," he demands her, teeth gritted. He has maybe a tiny amount of pity for her.
So young, yet still fighting with this hopeless cause...
He doesn't want her to go back into enemy territory, with mad Bellatrix and insane Dolohov lurking, but he has no better choice.
The girl glares at him once more, then says, "Malfoy." But she doesn't sound angry. She sounds disbelieving. "Bloody renegade," she completes.
"You've had your say, girl. Now-"
A few fatal curses fly past.
"LEAVE!"
Little bit I wrote about Lucius/Tonks, but really it's Lucius/Andromeda/Tonks. This takes place in the Department of Mysteries, if you hadn't figured it out.
