Home and Away spoilers follow for UK viewers.

Home and Away has released a new trailer which teases the backlash over Mackenzie Booth and Levi Fowler getting caught out.

Levi and his patient Mac have been having an affair after developing a romantic connection, unbeknownst to Levi’s wife Imogen.

Things will get even more complicated next week when Mac finds out that Levi and Imogen are planning on starting a family together, leaving her confused on what to do.

Now a new trailer for Australian viewers shows Levi’s sister Eden discovering the affair after catching him and Mac in the act.

Eden has already unknowingly helped to cover up her brother’s affair, as when Levi told Imogen he was spending time with Eden when he was in fact going to see Mac, Eden went along with the lie – thinking Levi was actually at work.

Eden is not only angry with her brother, as she also confronts Mali Hudson for his loyalty to Levi and Mac, and for keeping their secret for so long.

“Have we got a problem?”, he asks her, to which Eden says, “You’re giving my cheating brother a place to stay. You lied to my face.”

Mac also faces backlash from her business partner Felicity Newman, who disapproves of her behaviour after finding out about the affair.

“A married man. I can’t believe you’d go there,” she tells Mac, before saying, “I don’t know how you can live with yourself.”
