Season one

They were now teens, and her mother, Susan, was pushing her and her brother to make a comeback. During this time their old van, the Mystery Machine, (now in the possession of the gang) was acting on its own and causing serious trouble. It was believed to be the ghost of Flash, the original driver, who had come back for revenge. They were possible suspects to get out of the music industry because they had moved on to different things now. It was revealed to be their own mother, who was doing it for the band's publicity and they visited Flash's grave because he was their hero and with their upcoming show, they missed him dearly. They shocked their mother when they told her they're calling it quits and apologized to their other brother, Randy, who had been neglected by his mother in favor of his more talented siblings.



  • Mandy and Andy seem to be closer in age, whether or not they're actually twins is unknown.
