Casey Braxton is sentenced to weekend detention for his part in a botched robbery, and he soon becomes the target of fellow inmate Courtney (Joshua Brennan).
"Casey is trying to keep to himself," Younes told TV Week. "It's a juvenile detention centre, so it's not at the serious end of prisons, but it's still quite dangerous because there are a lot of precarious situations in which he finds himself.
"He's just trying not to draw too much attention [to himself]. Courtney is obviously the stereotypical prison bully and he instantly targets Casey."
New Home and Away character - prison education officer Zac Maguire (Charlie Clausen) - steps in to help Casey.
"[Casey]'s grateful to Zac for that, but he also doesn't know why Zac's helping him," Younes explained.
When Casey returns home, he is left feeling "betrayed" after discovering that Brax has allowed Kyle to move in with them. He also has to face his unresolved love triangle with Sasha and Tamara.
