The Summer Bay actor suggests that his character Casey Braxton could be the victim of a rage from his violent dad Danny (Andy McPhee).
As Younes discussed last week, Casey has been allying himself with his father to keep track of his unlawful moneymaking schemes.
"You see him turn up at the house and Casey opens the door and what happens from there is quite brutal," he told the latest TV Week.
"It's a sign of how nasty Danny can be, because he backhands Casey. How flippantly he backhands Casey alludes to everything Brax has said about how dangerous Danny is."
Younes added: "He's in too deep and it's really quite a scary storyline. Because not only is Danny possibly the worst father, because he's manipulating and brutalising Casey, but Casey deep down would still love to connect with him."
Teenager Casey's "biggest" storyline airs next week on the Seven Network, and in the UK this autumn. Get the Inside Soap magazine on your iPhone or iPad
