Das Ritual
Irene, along with Jack Holden (Paul O'Brien) and Martha MacKenzie (Jodi Gordon) do some digging to find out about the Believers. They find that there was a girl in Queensland who claimed that The Believers, and Jonah, had tried to impregnate her before she escaped them. After this revelation, Robbie is convinced but Tasha refuses to listen and stays with the cult after Robbie's ultimatum.
