Hermione felt like Ginny did - like crying. She covered her face with her hands, calming herself a degree. She didn't want Harry and Ron to fight - and not over this. Ron was being a prat. She could see them both getting too angry, so pulled out her wand and shouted, "Protego!". A barrier came up between the two, Hermione standing off to the side.
Ron glared at her, then shook his head. "How could you do that to Ginny?" he asked, indicating Ginny. Hermione looked down at her, her eyes filling with tears.
