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 onto different things now. It was revealed to be their own mother, who was doing it for the band's publicity. They shocked their mother when they told her they didn't want to be musicians again and apologized to their other brother, Randy, who had been neglected by his mother in favour of his more talented siblings.



  • Mandy and Randy seem to be close to the same age, whether or not they're actually twins is unknown.
