There'd been an odd shift between them since she returned the day before from Kingsley's flat. Maybe it started even before that, but seeing Antonin again reminded Hermione that she couldn't afford to be selfish. Not anymore. It was no longer Hermione versus the rest of the world. Even if she was never able to patch her relationship up with her husband, though his actions showed her that he was likely well on his way to forgiveness, she still had a son who needed to be protected. Draco could probably feel that she was pulling away again.
