Shock sets in as the DNA test results confirm that Andrea and Dee are identical twins and Heather is Dee's mother. Though they knew it was a possibility, Toadie and Dee are stunned as to how this came to be. They need answers, but that means a visit to Heather to learn about the pregnancy. Dee is too confronted for that, so selfless Toadie visits Heather on his own, demanding that he tell her the truth.

Heather details the story of Andrea's birth, recounting a seemingly unremarkable labour in a hospital in Perth. Frustrated, Toadie can't understand why Heather would lie, but knows her story can't be true as something isn't adding up. Toadie decides to request a check of the records at the hospital Heather named… only to be further baffled when there are no records whatsoever that Heather was ever a patient.

Dee begins to wonder whether the red headed woman from Andrea's memories may have something to do with everything. She recalls a red headed woman being at her birthday parties when she was younger. Increasingly baffled, Toadie suggests putting Heather under hypnosis may be their only course of action.

Meanwhile, Roxy's attempted seduction of Paul ends in rejection for Roxy and turmoil for Paul. Embarrassed and fed up with everything in Erinsborough, Roxy decides to leave town. Dismayed by the news, Terese intends to go out and stop her but Paul reveals Roxy's attempted kiss, explaining that it was an attempt to hurt Terese. Aware of Roxy's anger at Terese, Paul goes out to look for her instead.

Elsewhere, having found out about Sheila and Paul's meddling, Gary is on the war path. Furious that Paul has attempted to sabotage his relationship again, Gary shirtfronts Paul at his engagement party. It's not just Paul that Gary's raging at, he's also bitterly disappointed in his mum for placing Kyle's happiness above his own. With Gary convinced external forces have caused his relationship woes, Amy delays breaking up with him. If she did it now, Gary would blame it all on Paul and Sheila, but Amy wants the decision to be clearly her own and decides to bide her time until the storm passes.

When Paul offers a brutal, but truthful explanation of why he believes Kyle is better for Amy than Gary, Gary's fury rises. Kyle bears witness to Gary's seething anger at Paul. Later that night, Paul is viciously attacked. Has Gary's rage pushed him over the edge?
