(soft melodic music) (seagulls cawing) (waves lapping) - [Pete] Oh, God.

- Dad, it's Mum.

The police have called me, but they want us to ID the body.

- [Rosaline] What was she doing on the Isle of Man?

How's Jim and the kids?

- [Becca] Oh, he's good, yeah.

How's work?

- [Rosaline] (sighing) Just dandy.

(soft melodic music) - [Becca] I miss you, you know.

- [Rosaline] No, you don't.

- [Ian] Your mother, she was meeting a friend for a walk.

- She had a friend here?

- [Rosaline] It would seem my mother was living a double life.

- You don't wanna know what she was doing here?

- [Rosaline] No, because I don't like picking at scabs.

- Yes, you do.

- I get it, Becca, she lied to us.

- No, Rosaline, she lied to me!

(soft melodic music) - Everything was about you and Mum!

- [Becca] Don't judge me.

- You judge me all the time.

(soft melodic music) Who are all these people?

- I'm Cathy, I'm a dear friend of your mother's.

- I know you were having an affair with my mum.

- [Pete] She was happy here.

- I'm sorry your mother was so closed off about her experience here.

- She's been coming here for eight years?

- [Pete] She wanted to tell you, but the timing was never right.

- [Richard] You never really know someone, do you?

- What's going on?

- [Becca] I just feel so on my own handling everything!

I can't do this.

- Are me and you all right, Becca?

- [Rosaline] It's just us now really.

- Who is dealing with getting your mother back to the UK?

- She wanted to remain here.

- We need to respect Mum's wishes.

It isn't easy being a sister.

My therapist says we were forged in the same fire.

- No more secrets.
