Catherine is still haunted by Kirsten's death, and her depression spurs her on her quest to find Tommy Lee Royce. Realising that the net is closing in on them, Ashley orders Tommy to 'dispose' of Ann, but instead he holds her prisoner in his mother's... (more) cellar. Following her hunch, Catherine manages to speak with Helen face to face, and is stunned when Helen admits everything. With all falling into place, Catherine's heroic actions are shattered when Royce murderously assaults her, leaving both Ann and Catherine to fight for their lives.
