Dad and Sister.

Name: Theo Davies
Age: 43
Occupation: Muggle Doctor
Species: Human, Muggle (This can be changed if you feel so inclined)
Sex: Male
Wealth: Quite rich.
Personality: Quite assertive and rude. Doesn't really like Taylor because she's bisexual, but he has learned to be civil around her. He adores Taylor's little sister, but Taylor is very protective of her around him and hides them both away from him when he's around. He is very sarcastic and rude to Taylor, but not when Lili's around.
Appearance: Brown or blonde hair, pale and quite tall.
Importance: He's quite important to Taylor's life, because he made her want to try hard in school so he could finally be proud of her. I think he'd be good as a charrie, because Taylor would try to interact as much as possible with him. Keep in mind that he is a muggle, though, and British.

Name: Lili Davies
Age: 8 or 9
Species: Human, Witch
Personality: Lili is very shy and quiet. She doesn't talk much t anyone except Taylor, and the two talk a lot whenever they can. Lili learned to write quite early so that she could Owl Taylor if ever she couldn't talk to her. Despite getting along well with Taylor's dad, she is rarely allowed to see him and stays with her sister through a lot. She loves her sister very much, and appreciates her singing, dancing and performing a lot. She accepts Taylor for being bisexual, but that's partially because she barely understands what it is.
Importance: Lili is one of the most important people in Taylor's life, and the two interact a lot. She would be good as a charrie so that Taylor can show how much Lili means to her.
