Armed with the DNA proof that Dee, Heather and Andrea are related, Toadie organises for Heather to be hypnotised to see if she can remember the truth about the birth. With both Toadie and Karl present, Dr Robinson puts Heather under and helps her to recall what really happened. Contrary to her constructed memory of a pleasant birth in hospital, Heather actually gave birth under traumatic circumstances in a shelter known as Gartside Grove. She also recalls a red-headed nun, which prompts Dee to wonder if this is the nun both she and Andrea recall from their childhood.

This information is enough for Mark's colleagues in Perth to track down the nun in question. Everyone is amazed when a guilt-ridden Sister Grace catches an overnight flight and turns up in Erinsborough first thing in the morning. Dee, Heather and Andrea finally hear the grisly tale of what really happened all those years ago – Heather gave birth to twins, and the nuns gave one of her babies to the young Bliss couple who wanted a child.

Meanwhile, Roxy discovers Paul lying unconscious by the lake after being struck from behind with a heavy object. Everyone rushes to the hospital, where Paul undergoes surgery to stop internal bleeding. Throughout the tense overnight wait, Roxy is subdued, something Harlow notices.

The next morning, a lucid Paul accuses Gary of being the person who attacked him, something Sheila also worries might be true. However, Amy remains loyal to Gary. Later, a furious Gary turns up at the hospital. Aaron stops him from confronting Paul and making matters worse. Roxy witnesses his fury and subsequently shocks everyone by claiming that she saw Gary at the scene of the attack, something she curiously neglected to mention earlier.
