Ron knew that she would say this, but it didn't mean he was done trying. If she didn't know that then she didn't know him at all. "I didn't mean for you to do nothing. But this isn't Voldemort, Hermione. We don't know what we're dealing with this time. We can't just jump headfirst into this." He knew that the DA was meeting for this purpose, but that wasn't the reason he had even agreed to go. They were just lucky that some of them had some training in investigation now.

Ron loved Hermione with all of his heart and couldn't imagine being with anyone else no matter how many times their relationship seemed to fall apart over the past five years. They always came back to one another and even if she did somehow find someone better than him, he did not ever see himself finding anyone else in the world that was as amazing as Hermione Granger was. "You've just got to be careful, 'Mione."
