Rosalie have been Hermione's one and only best friend for a long time now. They met each other a year ago when Hermione first arrived in Avalon. When people mocked and threw stones and objects on her accusing her of being a witch. Just because her parents were both dead when she was a still a baby. And after that she disappeared without a trace.
The whole village began to doubt her identity when she returned to the Larabee's home, claiming to belong there. But when she showed them a scar that was caused from the fire that killed her parents that day. They had nothing else to oppose with than to call her a witch. Because her parents were both dead, how then did she manage to be alive after she disappeared completely as a child.
Some even went as far saying she was the one who killed her parents with the fire because her witchy abilities had started to manifest by that time.
