Traitor

"Aw, is the ferret upset that I'm here?" she asked, eyes dancing with her amusement.
Malfoy glared at her. "Keep that up, Potter, and I'll have you moved to the dungeons. I don't need to keep you in a bedroom in my home."
Adelaide clicked her tongue against the roof of her mouth as she continued to turn about his room. "Ah, but your mother wouldn't allow that, now would she?"
Malfoy sneered. "Who said my mother had to find out?" He raised a brow as he came to stand in front of her, towering over her in way that should have been intimidating. Adelaide only felt heat rise to her cheeks and mentally cursed herself a fool.
She forced herself to smile smugly as she brought her face closer to his. With just a movement, a spasm of a muscle, their noses could brush. Adelaide could feel Malfoy's breaths fan on her cheeks as she played coy for a moment. And then she pulled away, and she could practically feel him gape as she turned to exit his room.
With a satisfied shrug, she chirped, "I did." She didn't see him until dinner the next day.

Adelaide could explain her goals in three sentences tops.
1. She was going to become the most powerful, respected, and feared witch in existence.
2. She was going to murder her brother, Harry Potter.
3. She would follow in the footsteps of Gellert Grindelwald and honour his memory, even if the route she was taking to do so was eerily similar to Tom Riddle's.
Unfortunately, a certain Malfoy was getting in her way of attaining them, as unintentional as it was. Would her emotions for the boy ruin all of her visions for the future by providing her a weakness, or would it enhance her to become the greatest being in all existence?
She supposed only time would tell.
