Kaneki Ken could fit in as an outsider with a dark past, much like some RWBY characters. His struggle with his dual nature as a human - ghoul could parallel the internal conflicts of RWBY characters dealing with their own powers and identities. For example, Ruby's journey to understand her silver - eyed warrior powers.
I don't know who Ken is specifically. The story he is telling could be about his personal experiences, like a trip he took, or it could be a fictional story he made up, perhaps a fantasy adventure with magical creatures.
Whether Ben Carson's story is true is a complex question. It involves looking at multiple factors such as the reliability of the sources reporting it, his own statements, and independent verification. In some cases, it might be a combination of truth and exaggeration.
There could be his best friend, who has been with him through his journey of self - discovery. This friend might be someone who is also part of the same community and understands Carson's feelings and experiences.
There might be a Shelby Carson who is known in a local community or a specific industry. Without more details, it's difficult to tell the real story. It could be that she is a regular person with her own unique experiences, relationships, and achievements in her personal or professional life.
