 What does newcomer Heather want?

Home and Away launches a big new storyline for Marilyn Chambers on Australian screens this week.

The long-running soap hints that Marilyn's past could be explored when a new arrival takes an unexpected interest in her.

Sophia Nolan has been cast in the role of newcomer Heather, who makes her first appearance at Australian pace this week.

Heather first arrives at the Diner as a new student for Roo Stewart, who has recently decided to take up tutoring.

Spoilers released by TV Week have revealed that Heather ultimately opens up over her past, as she once had an affair with a married man and ended up pregnant.

Heather was separated from her baby when the man and his wife took custody of the child.

Inspired by her own past, Heather wants to become a lawyer to help other mothers who have been separated from their children.

The new plot will be Marilyn's first big storyline since her involvement in the gas attack at Salt, which led to a drastic temporary change in her personality.

Earlier this month, Emily Symons – who plays Marilyn – appeared on ITV's This Morning to promote the daytime soap.

When asked about the recent axing of rival serial drama Neighbours, Emily replied: "We're all very sad for our colleagues and our friends in Melbourne.

"Wasn't the finale the most beautiful episode you've ever seen? It was so emotional and wonderful to see all the old characters coming back – it was really special."

Home and Away airs weekdays at 1.45pm on Channel 5 and 6pm on 5STAR. First-look screenings air at 6.30pm on 5STAR and the show also streams on My5.
