April and Heath had a one-night stand in the soap's 2011 season finale, as they sought comfort in each other during troubled times for their respective personal lives.
As Home and Away returns to screens in Australia next Monday, April is keen to keep seeing Heath (Dan Ewing) - but is left disappointed when he doesn't seem interested.
Fish told TV Week: "As soon as April sleeps with him, she can't get him out of her head. [But] he wants absolutely nothing to do with her. So it's a really hard situation she's found herself in."
Revealing that April tries to win back Heath's attention at her sister Bianca's engagement party, the actress continued: "April's a really smart girl, and to put it nicely, Heath isn't exactly the sharpest tool in the shed. So she gets really dressed up and basically looks as hot as she possibly can in order to win him back."
The pair later share a steamy encounter on the beach, but when this is witnessed by a shocked Bianca (Lisa Gormley), viewers will be left to wonder if the blonde will put a stop to their relationship.
Home and Away airs these scenes next week on Network Seven in Australia and in February on Channel 5 in the UK.
