Leonardo (2011)

S1E5 It Must Be Love

Lorenzo's pampered cousin Valentina visits, capturing Leonardo's heart instantly. She reciprocates his feelings but soon shifts her interest to Tom, not realizing that Tom is actually Lisa in disguise, as female art students are prohibited. When Valentina uncovers Lisa's true identity, she plans to reveal the secret. Luckily, Leonardo's newest creation—a bicycle fueled by explosives—intervenes just in time to prevent Valentina from spilling the beans.
