Draco wasn't sure he wanted this to be about him, about their past. A part of him - his pride, really - was glad that he'd survived the worst part of his life without her, hadn't needed her, in the end, even though it would have been much easier with her by his side. He'd been remembering that a lot lately, allowing himself to feel stronger for it rather than upset about it. He had become a survivor, plain and simple, and made his choices accordingly; maybe now Pansy would understand that better.
"It's alright," he said, holding her gaze, even though he wasn't sure what she would read in his expression. He would be here for whatever she needed tonight, to recover; he wasn't going to hold their past against her. "I forgave you years ago. Honest."
It hadn't been resentment that he'd held onto all these years, just pain. Funny how he remembered the pain of losing her so much more keenly than that of taking a life, though it had all been twisted together inside him for ages. It seemed she'd taken on the guilt for that now, and selfish as it was, that went a long way toward making him feel better about it.
Of course, he was assuming that she was talking about that, and not apologizing for being here, or for what she'd done tonight. She hadn't done anything to him tonight, and the tone of her voice led him to believe that he'd made a safe assumption.
