Ruby was then raised alone by her mother and that's why she has her mother's last name. Then when Ruby's mother died she went to live with her biological father and his family, the Xiao Long's.

It all fits. They're blood related sisters with different last names. The lyrics to Red Like Roses Part II makes sense as being between Ruby and her mother. Especially if you consider they'd be a single parent and an only child. It talks about how they were the whole world to each other. Her mother was the only person she had. Which, I think, means the "white cloak" was Ruby's mom and she was visiting her grave. That theory could work. But Ruby and Yang get along too well for sisters who were raised by different parents. Afterall, Yang used to read bed time stories for Ruby.
