Home and Away's Levi Fowler to uncover worrying drugs secret

 Levi realises how much trouble his sister Abigail is in.

Home and Away's Levi Fowler will discover an upsetting secret in scenes airing in the UK next week, as he finds out just how much trouble his little sister Abigail is really in.

UK viewers were introduced to Abigail last week when she showed up in Summer Bay to celebrate her sister Eden's engagement to Cash Newman. But Abigail disappeared almost as suddenly as she arrived, when she left the party with Levi's stolen wallet in tow.

Next week, Levi is upset when he notices that Abigail is still stealing money from his bank account using the wallet that she took.

His girlfriend Mackenzie Booth urges Levi to block his card, pointing out that he's letting Abigail take advantage of him. But Levi admits that he doesn't want to cut his sister off, explaining that seeing her spending his money is proof that she's okay.

As Mac continues to push Levi, he agrees to block the card at last, and it isn't long before furious Abigail is back in town. As she confronts Levi for cutting off her cash supply, he worries about how unwell she looks.

Later on, Mackenzie fills Rose Delaney in on the situation with Levi and Abigail. Rose is quick to tell Mac about the money that was stolen from the surf club recently, suggesting that Abigail could have been responsible and that Levi covered for her.

When angry Mackenzie gets home, she confronts Levi over the stolen money and his lies, before announcing that Abigail needs to get out of her house right now.

Abigail heads for the bus stop but Levi follows her, grabbing her arm to stop her from leaving. When Abigail cries out in pain and breaks down, she's forced to show her brother her arm, which is covered in bruises caused by needles.

Levi is left worried by what he's seen and he urges Abigail to go to the hospital to have her arm treated, as it looks like it's infected, but she refuses to go.

As a compromise, Levi offers to treat her arm himself, so long as she comes home with him. When Abigail agrees, Levi quizzes her about the state of her arm, asking her what drugs she has been using.

When Abigail asks Levi for more money and he refuses, she claims that she will do whatever it takes to find the cash somewhere else. Worried Levi tries to get through to his sister, desperately trying to explain that she's putting her life in danger.

But as Abigail suffers from withdrawal symptoms, she begs Levi to help her, insisting that she just needs to get through the next few days.

Emotional Levi decides to give his sister the money that she needs, just to prevent her from doing anything dangerous to get hold of the cash. But is this the start of a slippery slope for the siblings?
