Next week on Home and Away in the UK, as Roo attempts to settle her foster child into her new life, Eliza’s fascination with death leaves us wondering whether she’s bringing danger to the bay.

This week saw the arrival of Eliza Sherwood (Martha Kate Morgan), a 14 year old girl who Roo (Georgie Parker) was asked to foster.

Eliza needed a new foster parent as a matter of urgency, after her last foster home was destroyed in a fire. Everyone got out safely, but Eliza was left with a burn to her arm.

Roo began her journey into fostering last year, after being inspired by Tane’s (Ethan Browne) request that she apply to foster the baby he found on the beach.

Although the baby’s mother, Sonia (Olivia Beardsley), eventually took her daughter back into her care, Roo was inspired to push forward with her application.

Roo was nervous about taking on a foster child, despite having completed all of the relevant courses, but Marilyn (Emily Symons) buoyed her by reminding her of how she successfully nurtured Maddy (Kassandra Clementi) and nephew Ryder (Lukas Radovich) over the years, and assured her that she and Alf (Ray Meagher) will be there to support her along the way.

When Eliza arrived at Summer Bay House earlier this week, the teen made it clear that she wouldn’t be sticking around for long.

While it was obvious that Roo was feeling uneasy about her new foster child’s demeanour, Roo put it down to her being frightened after her traumatic ordeal.

“That’s why I mustn’t give up on her,” Roo stated, clearly holding her reservations back. “No matter what.”

However, it quickly became clear to viewers that Roo has every reason to be concerned. Alone in her room, Eliza opened her musical box, the only possession she was able to save from the fire, and carefully looked through the items inside – a white feather, a lock of blonde hair, a family photo with the parents’ faces scratched out, a ring, and a lighter!

As she flicked the lighter on and stared transfixed at the flame, we were left wondering whether Eliza was the one who started the fire.

The following morning, as Marilyn went out of her way to make Eliza feel at home, preparing her a varied breakfast, Eliza was dismissive of her efforts.

Soon after, she lifted a $50 note from Marilyn’s handbag, and when she returned from a shopping trip with a thank-you card for Roo, it led to a tense confrontation when Roo asked how Eliza paid for it.

Eliza was upset that Roo appeared to be accusing her of stealing, but when Roo apologised and went to hug her, Eliza’s cold and blank stare made it clear that she had Roo right where she wanted her.

Next week, Roo continues to introduce Eliza to her friends in Summer Bay, as they head to the coffee cart, where she meets Justin (James Stewart) and Leah (Ada Nicodemou).

Eliza continues to be distant, not wanting to engage with Roo’s friends, and makes a quick exit as soon as she’s got her hot chocolate.
