I Never Thought It Would Be You, but I Am Damn Sure Glad It Is

Gabrielle and Alicia Trimble are fraternal twins and were born to pure blood parents who were both Head Boy and Head Girl for Ravenclaw. When the girls got their acceptance letters, their parents were a little worried for two reasons: 1. Because the girls have always been a little competitive with each other they would be fighting to get the Head Girl spot for Ravenclaw and 2. Or they would not be in the same house as every one else in the family. The second reason was more directed towards Gabrielle. According to their mother Gabrielle has always had a bit of a mean streak. Will it be enough to keep her out of Ravenclaw?
