What secrets was Mary hiding?

Soon after they arrived to identify and repatriate Mary's body, it became clear that she hadn't just been there on holiday - she had in fact set up a whole other life there.

It turned out that some years previously she had decided to track down her birth mother, following the death of her adoptive mother. In doing so, she had come to the island and, once her birth mother died, had inherited a house there.

She had subsequently been splitting her time between the house on the island and Manchester. While on the island, she had built up a community, becoming friends with Cathy and starting a romantic relationship with Pete.

She had also later become aware that she was suffering from Alzheimer's disease - Richard had known this, but Becca and Rosaline had been kept in the dark.

Becca and Rosaline had been shocked to discover all of these secrets, with Becca feeling particularly betrayed having thought she was close with Mary.

How did Mary die?

After spending some time on the island, Becca and Rosaline are informed by the police that Mary died of a morphine overdose - one which they believe was a self-administered, purposeful attempt by Mary to take her own life.

It later transpires that Mary took the morphine from Cathy, after she found out she had Alzheimer's disease, wanting to take the end of her life into her own hands.

Cathy had the morphine because she worked as an end of life doula, although she said the morphine was for her own personal use and she mostly offered cannabis for those she worked with.

At the end of the series, the police had started investigating Cathy for her possession of the morphine and involvement in Mary's death.

What happened to Becca and Rosaline?

At the end of the series, having had marital difficulties, Becca and Jim reconciled, agreeing to talk more and make a plan for a better life together.

Meanwhile, Rosaline found out that she was fine after her biopsy, and finally told Becca that she had been dealing with the anxiety surrounding it for the whole trip.

The pair came to appreciate the life Mary had built on the island and Rosaline even said she would go to the police to try to convince them of Cathy's innocence in her death.

They spoke with their father, Richard, and told him that they did not intend to repatriate Mary's body - she had recorded a video message saying she wanted to stay on the island after she was gone.

Richard was furious at the suggestion and at what he saw as Mary's betrayal. He left the island on his own, and it appeared as though Mary's body would be remaining on the island - however, this remained largely unresolved at the end of the series.

Becca, Jim, Lauren and Molly all headed home, but Rosaline decided to stay on the island and in the house - she said that she had found a job opportunity she may apply for and seemed happy.

She had also started up a relationship with taxi driver Jacob, who she had formed a connection with during her trip.

The sisters bid goodbye with a hug and then parted ways once more.
