First, it was the newspapers – especially The Daily Prophet as people raised their voices in anger, hurt and desperation of why Pansy's case should be treated as special, her rapist facing the death penalty when their own daughters, girlfriends, fiancées, sisters, friends would not be allowed the same justice.
Then the howlers started arriving – every professor and all of their friends desperately attempting to attend to them in order to protect not only Pansy who was growing more fragile in front of their eyes everyday but also Ron who was struggling to keep it together enough to keep Pansy together.
The stress of watching Pansy continue to lose weight when she had no business doing so in the first place only added to his own stress because Madame Pomfrey had finally given up in trying to get through to Pansy and had started in on Ron; cajoling him into making her take care of herself.
But there was only so much he could do when students at Hogwarts started adding their own opinions in the form of whispers in the Great Hall, the halls outside the classrooms, the classrooms themselves, and the library. He had to stand there and watch the Pansy he thought had finally disappear start to return slowly: first refusing to be anywhere that Ron wasn't, then walking so close to him that he found himself tripping over his own feet as well as hers, to clinging to his hand and finally his sleeve.
However, in spite of everything that had been building to this moment, what hurt the worst was the morning when he emerged from the bathroom ready for class and Pansy was dressed, not in her uniform, but her favourite pair of jeans and his Cannons' Quidditch kit. Kneeling in front of her, he pushed her hair out of her face and lifted her chin. The evidence of her tears broke his heart even before she whispered, "I'm sorry Ron. I can't do this. I can't stand the whispers anymore."
