When he hadn't returned to his flat for over twenty-four hours, Hermione tried to ignore the sinking in her gut each moment she thought about Draco. This was part of his life. As a tracker, he could be gone for an even longer period of time than she was used to. If his travels took him out of the country, there was no telling when he would be expected back. With no way of knowing why they were summoned to the Dark Lord the day before, she couldn't even begin to estimate how long it would be before he crossed the threshold of his flat again.
