April recently admitted that she still has feelings for her former partner Dex and that, after he breaks up with Lottie (Morgan Weaving), he decides to tell her straight away.
However, his revelation is not well received by April due to the poor timing while her sister Bianca (Lisa Gormley) is in hospital.
"April can't think about anything else besides her sister and making sure she gets better," Fish told TV Week.
"So she is completely thrown when Dex confesses his love for her, and is almost annoyed by the fact he's chosen now of all times to tell her he loves her. It seems like a really inappropriate time."

However, Irene (Lynne McGranger) later tells her that she may have made the wrong decision.
"Irene comes out with a few things that make April stop and think. She tells her, 'You've been pining over this boy for months and he wants to be with you and you've thrown it back in his face. What are you doing?'
"April needs that snap into reality and go, 'What am I doing? I love him and I need to try and make this work'."
April later discovers Dex in the diner, with Fish adding: "It's so cute. April just comes straight in the door and Dex starts rambling on and April jumps in and gives him a big kiss and says, 'I love you and I always have'. It's very sweet."
Fish added that she was glad that the pair have got back together, saying: "Ever since I started the show, it's clear there's something very special between those two characters.
"It's a situation where I think they belong together."
