After Helena died, she came back as a ghost. She was still determined to erase her mother completely from her life. And she did. No one knew who she really was. She became Ravenclaw's official ghost. She got a nick name. The grey lady. She liked this very much because it kept her old life hidden. She never interacted with the baron again. ( Now called the bloody baron as he became Slytherin's ghost. ) The bloody baron was still ashamed of himself and imprisoned himself with chains. He could control peeves the poltergeist who was most likely scared of him as he had a blood stained shirt. Helena was no longer in her mother's shadow. And the bloody baron was happy being Slytherin's ghost. He still never forgave himself for what he had done to his love. Helena lost the diadem when she was killed. Though tom riddle later found it and turned it into one of his horcrux's.
