This wasn't the way it was supposed to be. He wasn't supposed to really talk to her, to sympathize with her, even, eventually, to like her. It wasn't part of his perfect plan. She was supposed to be a step stool, a rung on the ladder of his perfect domination. And, he had to admit, she'd served her purpose beautifully. She'd done everything he asked, no questions, no arguments.
Of course, he'd known she loved him. Silly girl had from the start, with no regard to that husband she was supposedly so in love with. Love was such a pesky emotion, it always got in the way. Still, it kept her content with doing whatever he told her to. Until she started to get needy.
He'd tolerated it. For a while, and then it had started to get incredibly inconvenient, and frankly annoying. Somewhere, deep down - for yes, he truly did have a depth no one had ever seen - he knew he didn't really feel that way, but even his subconscious refused to accept this. He continued to degrade her, to hold her at arm's length, telling himself she was just another pawn, entirely disposable.
And the stupid girl didn't seem to care. Throughout his abuses, she worshiped him, never recoiling even when he caused her physical pain. She was willing to bear whatever he threw at her, out of her foolish love for him. It made him so angry. Why couldn't she just run? Why couldn't she, like so many else, give him up for lost and just leave in terror and disgust. He knew he wasn't worth her love. He knew that she didn't care, and would love him anyway. He hated her for it.
He pondered all these things as he crept down the hallway silently. Down to the end, where he knew he would find her sleeping alone, her husband out on an errand. He knew it would be that way, because he'd arranged it. He was meticulous, and always arranged for their meetings to be virtually risk-free. Not that he cared if the husband found out, but she did, for some unfathomable reason.
As he pushed open the door, just a shadow in the dark, he argued with his own mind. Of course he felt nothing for her, she was worthless, and that's why he was doing this. But then, if he truly didn't care, why was he doing this? He couldn't come up with an answer for that.
And so, staring at her beautiful form sleeping so peacefully, the two words he uttered were not the three he longed to say, and which she longed to hear.
"Avada Kedavra."
