I think Charles gave Daniel the second body for a reason. If I am not wrong it could be that the doctor and Charles were enemies. It could be that doctor also had a second body, and married Daniel's mother. Then had daniel. Also I think Charles got to know about the second body and took it away from Charles. Then he gave the body to daniel???? Idk now. I just want to know wtf is happening.
ho***
Yeah it's a disease
