Paul and Terese, who are on their honeymoon in London, fill Prudence in on Harlow’s new life in Erinsborough. But why isn’t Prudence in any hurry to reunite with her daughter?

Meanwhile, back in Ramsay Street, Harlow comes clean to Paul’s daughter Amy Williams (Zoe Cramond) about why she didn’t want Paul and Terese to meet Prudence. It seems her mum is a member of a cult called the Restoration Order!

Prudence abruptly ends her time with Paul and Terese. But as she hurries off, she’s stopped by a mystery man Graham Isheev (played by telly presenter Richard Arnold) who seems to have a strange hold over Prudence and encourages her to end her relationship with Harlow!
