He hummed in understanding. In the past, he hadn't had much of a relationship with any of the Slytherins, and he assumed that since he was pure and not a Gryffindor, he was left largely alone, and he hadn't gone out of his way to antagonize any of them. But Crabbe and Goyle had always driven him crazy. He could even find things to respect in Pansy, and he could barely stand her, but the two of them were another matter entirely. "I can't blame you for not enjoying yourself, then." He didn't really know why she was friends with them in the first place. But she must have her reasons, and he didn't want to badmouth them, especially so soon after Crabbe's death.
He couldn't help but smirk at her reaction. "It's fine." He didn't know why she seemed so nervous almost. "Unless you've suddenly changed your mind and decided that you can't bear the idea spending the ball with a lowly Hufflepuff, we're still on."
He was teasing her again, something that came surprisingly easily, but there was a genuine question there, albeit a well hidden one. In the past, Millicent had been largely inseparable from her friends; the Slytherins had mainly come as a set, and they had never struck him as the kind of group who were open to breaking tradition. It made him wonder, then, what her friends thought of them going together- and he already imagined that Pansy was displeased. And that brought up the question of why she was even bothering with him at all.
