There was no way Millicent could deny Draco when that sort of look crossed his features. She'd seen it only a few times and even then it was directed at Pansy.
She stood still when the knock sounded on the door. She hadn't done anything wrong - technically. And she did know a spell to obscure herself from Draco's view if she had wanted to use it while she changed. So, if it was Pansy at the door, she'd have something to tell her - and nothing had happened in any case.
"Draco, why is this door locked?" Pansy called, her voice a bit muffled, as if she were being pressed into the door.
Millicent stepped back, quickly doing up the last of her buttons so she could step into her shoes and throw her tie around her neck. She took the seat across from Draco and slid her shoes on before she sat down and primly crossed her legs.
