Natalie and Brax are currently growing ever closer in episodes airing in Australia, but they soon agree to cool things down for the sake of Brax's younger brother Casey (Lincoln Younes).
With Natalie counselling Casey as he faces a charge for killing his father Danny, she realises that the teenager needs her full attention at the present time.
Catherine Mack, who plays Natalie, told TV Week of the storyline: "Natalie's worried their relationship will get in the way and Casey will stop talking to her if she's going out with his brother. She cares about helping Casey more than her own personal life."
Revealing that his character agrees with Natalie's decision, Brax actor Steve Peacocke commented: "Casey is the centre of his universe and Brax has pledged that he would be the father they didn't have.
"It leads to a point where they have to put their relationship on hold because of Casey and it's difficult for them both, but they both know it's best for Casey."
When Casey learns of the pair's decision, he insists that they should put themselves first - but Natalie stands firm.
However, Mack added that Natalie and Brax will be sharing plenty more screen time in the coming weeks.
She explained: "Their attraction to each other is undeniable, and even though it's not the key focus, they can't help but continue to be around each other and be attracted to each other. There's also definitely drama coming to the Bay where Natalie and Brax will have to join forces to work together."
Home and Away airs weeknights at 7pm on Network Seven in Australia. The show returns to Channel 5 in the UK on Monday, September 3 at 6pm.
