S2·E13 Arabesque

Former 'World Below' resident Lisa Campbell – now a world-famous ballerina — returns to the tunnels for refuge, desperate not to testify against her controlling and arms-running boyfriend. Her return unnerves Vincent—who loved her when they were young, but who injured her once during an embrace, a major reason he fears physical intimacy with Catherine. But Catherine consoles Vincent and convinces Lisa to face the authorities and do what she can to put her boyfriend away for his crimes.
