Nadine Bernadette Weasley, twin sister of Ronald. However, sorted in to Ravenclaw, she still manages to become best friends with the trio, making people call them the Golden Quartet. She was the excluded member, though she was the one with all of the smarts. She knew everything about everything, because over her photographic memory, she can memorize every second of everyday. The thing with her little 'condition', is that if she uses it too much, she could explode. But she doesn't know it yet. (I only own about 6 characters or so, but don't count me on it. All the original characters of Harry Potter go to J.K. Rowling)
