Home and Away has introduced Dean Thompson's half-sister to Summer Bay.
Emily Weir has been cast in the role of Mackenzie Booth, who revealed her true identity to Dean in Thursday's Australian episode (June 20).
Viewers in Australia saw Mackenzie make her first appearance on the show last week, when she was introduced as the new owner of Salt following Brody Morgan's departure.
It was always clear that there was more to Mackenzie than met the eye as she seemed particularly interested in getting to know Dean.
The latest episode on Channel 7, which broadcasts Home and Away in Australia, saw Mackenzie come clean to Dean about how she's the daughter of his father Rick.
Mackenzie's mum is Rick's first wife, who he cheated on when he hooked up with Dean's mother Karen.
None of these revelations went down well with Dean, who was suspicious over Mackenzie's motives for buying Salt and moving to Summer Bay.
Although Dean's girlfriend Ziggy Astoni (Sophie Dillman) encouraged him to give Mackenzie a chance, early tensions suggested that it may take some time before these two half-siblings are on good terms.
Fortunately, it wasn't all bad news as when Mackenzie received a phone call from Rick while Dean was around, she declined to take it and showed there's no love lost between her and her father. Could this be something Dean and Mackenzie have in common?
Home and Away fans in the UK will see these scenes on Channel 5 on July 22 and July 23.
Home and Away airs weekdays at 1.15pm and 6pm on Channel 5 (UK) and Mondays to Thursdays at 7pm on Channel 7 (Australia).
