The Good, The Bad and the Ollie

Simon brings Oliver back home from the university using the VisiCron to help him with an invention. But there is a glitch in the VisiCron and Oliver is split into two, one nice and the other one is naughty. The nice one cannot tell a lie but the naughty one is seeking revenge on all the people that treated him bad in high school so Crystal and Simon need to find him before he does something really bad.
