Sienna Blake (Rose Riley) only cares about her job, and getting the best out of her agency’s models. She’s seen Bella as a distraction, someone who will end up pulling Nikau away from his career as her jealousy builds over his new jetsetting lifestyle and the attractive women he’ll be shooting with.

She knew that breaking Nikau and Bella up was the best way to advance Nik’s career, and would stop at nothing to achieve it.

When she made Allegra (Laura McDonald) send Nikau a photo of Bella and Emmett supposedly cuddling up together, her plan worked perfectly. Poor Nikau was devastated at the sight of what he thought was his girlfriend being unfaithful, and fell straight into the arms – and bed – of Sienna.

After they spent the night together, he was racked with guilt. While he wanted to keep it a secret, a constant stream of subtle hints from Allegra, and Sienna’s constant presence in the bay, meant that the truth was bound to come out eventually.

In last week’s Australian episodes he confessed all to Bella. The news hit her hard and she immediately ended things with her boyfriend, heartbroken at his betrayal.

This week, Nikau has had enough. He tells Sienna that he’s done with the agency, and he’s done with her. However, this comes as no surprise to Sienna, who’s always one step ahead. She swiftly reminds him that he’s bound by his contract.
