 Lucas temporarily becomes an adult after being bitten by a mayfly, which has an exceedingly short lifespan.This "adult" Lucas, played by Andrew Tarbet of "The Famous Jett Jackson", poses as a substitute math professor, hangs out with Principal Amanda Durst, and even berates Victor Pearson for not treating Durst with more respect.Lucas lacks confidence in his love life, except during one wormhole-assisted bout of bravery, during which he suavely secures a date with a beautiful new student from Italy, even speaking to her in Italian.
