1. They are sister but Ruby lived with her mother.

2. She tries hard to be the best huntress she can be to honor her mother, this brings recklessness. She also tried hard at first to prove herself to Weiss.

3. Losing her mother has affected her but with the help of Yang she turned it into a positive and that is part of the beauty of a simple soul.

Maturity comes with experience. Loss of a loved one makes you think about mortality. Your own and those around you and that realisation bring a bit of maturity. But a 15 year old remains a 15 year old. Should she be brooding all the time? It's been several years and she had help from Yang. But it still drives her to be the best she can be. A lot of teen lose their parent at a young age.

I believe a lot of you are under a misconception that losing a parent makes you almost an adult. Or at the very least mostly sad all the time. You learn to deal with it and you move on. You always remember but you move on.
