They were nearly at a cell that Hermione deemed far enough away to be safe from anyone accidentally stumbling on them, when he finally gathered his wits enough to pull back. His sudden stop unbalanced her, but only briefly. Releasing his wrist, she turned around and looked at him warily. She watched a smile slowly stretch across his face. His pupils were blown wide open as he stared at her. And it was all suddenly very overwhelming. She supposed she should be relieved that the potion had worked, but in fact, she felt more anxious than ever. To be looked at like that. To know that he was thinking about her. It was terrifying.
