Home and Away cult concerns as Andrew Lawrence's sister Tegan arrives

 Justin insists on strict precautions.

Home and Away introduces another new character to the Andrew Lawrence storyline on UK screens next week.

Sophia Forrest is playing the role of Tegan Osbourne, who arrives in Summer Bay to see Andrew after years of separation.

Justin Morgan fears the worst when he learns that Tegan is coming to visit, fearing that history could repeat itself after the previous debacle with Vita Nova leader Margot.

Margot posed as Andrew's mother a few weeks ago, tricking Justin into letting Andrew move away with her. Justin is now determined that he won't let anything like that happen again.

In next week's episodes on Channel 5, Justin insists on meeting Tegan for a coffee before she sees Andrew.

Justin is keen to verify that Tegan is the real deal, but she has photographic proof of her identity and turns out to be a research assistant for an environmental science department.

Tegan can also recall clear memories of her early childhood with Andrew.

Although Tegan has passed Justin's test, she makes it clear that she intends to take Andrew away with her.

This concerns Justin and his partner Leah Patterson, who'd prefer to have Andrew stay with them on a permanent basis.

Later, Andrew connects with Tegan despite Justin and Leah's doubts. Theo Poulos abandons preparation for Lyrik's next recording session in order to be there supporting him.

Tegan points out everything that she and Andrew have missed out on after being apart for so long, but she suggests that they can make up for it now.

Justin and Leah remain worried that Tegan is moving too quickly, so she agrees to stick around in the Bay for a while longer to avoid any hasty changes to Andrew's life.
