Hermione stayed by the door for another ten minutes after Malfoy left, foolishly hoping that he might come back. He didn’t. She went back to the living room, picked up the two empty bottles – one for each of them – and threw them in the trash while putting the one still full bottle back where Malfoy had taken it from. Mipsy offered to do it all herself or at least help, but Hermione wanted to do it on her own – it helped to clear her mind and didn’t let her panic.
