This week on Home and Away in Australia, Roo fears for her safety as the evidence against Eliza mounts, while Mac rocks Levi with a baby bombshell.

Roo’s (Georgie Parker) new foster child Eliza Sherwood (Martha Kate Morgan) has already managed to make some waves in the few short weeks she’s been in Summer Bay, but some shocking news could make Roo wonder whether she’s severely underestimated the 14-year-old.

Eliza came to Roo as an emergency placement last month, after her last foster home was destroyed in a fire.

Her fellow foster-siblings were still inside as the fire took hold, and all Eliza was able to save was her music box, in which she kept her most precious possessions.

But as Eliza settled in that evening, we saw that she was keeping some disturbing items hidden away in the box, including a lock of blonde hair, a photo with two faces scratched out, and more significantly, a lighter…

As Roo began home-schooling Eliza, she began to exhibit a strange fascination with medical science, or more specifically the process of surgery.

Eliza began looking up the techniques for major operations, as well as the implements required, and started watching videos, which Roo found a little disconcerting.

Both Alf (Ray Meagher) and Marilyn (Emily Symons) have already voiced their concerns about Eliza’s odd demeanour, but Roo pointed out that they had promised to support her in bringing a foster child to Summer Bay House, and reminded them of what Eliza had been through.

Unbeknownst to them all however, Eliza had already swiped a fishing knife from Alf after spotting it in his bait shop, and had added it to the collection in her music box.

Eliza also expressed an interest in babies, demonstrated when she walked up to stranger Harper (Jessica Redmayne) in the surf club and placed her hand on her belly, hoping to feel the baby.

She went on to steal an ultrasound printout from Tane’s (Ethan Browne) bag as she attended her first session of the youth program, which is when she found herself at odds with fellow student Scott (Finnian James).

Unhappy at his insistence that she return the scan to Tane, Eliza floored Scott with a punch to the nose.

It seemed progress was being made when Eliza later apologised to Scott, but when he later took her new phone off her in order to input his number, a furious Eliza smashed a bottle and threatened him with it.

When Roo asked Cash for some background on Eliza, he did some digging and found that Eliza had been forcibly removed from her parents at a young age before being placed in the custody of her grandmother.

When Eliza was 10 years old, her gran died after falling down the stairs. Eliza was found hiding in a cupboard and refused to leave, with police forced to drag her out so the coroner could get to her gran’s body.

Roo realised this was probably the reason Eliza reacted so badly to Cash coming over to talk to Eliza about the incident at the surf club, and comforted Eliza as she told her how sorry she was about what had happened in her past.

As Roo embraced Eliza, Marilyn was deeply unsettled when the teen looked over to her and gave a smile, having displayed nothing but aloofness towards her before that point.
