Juliet warns her father, Mondo, to back off during Sunday's visit to Fair City on RTÉ One and the RTÉ Player.
Mondo has been charged with Anto's death - and he is furious that Kira, Juliet's mother, spoke to a reporter about him.
In Sunday's episode, Mondo accuses Kira of making a deal with the reporter and demands to see her phone.
"Seriously, prove that I got it wrong," says Mondo.
"Get away from her!" says Juliet.

"Move," Mondo demands.
"Or what? You'll punch me?" replies Juliet.
Fans can watch what happens next on Sunday on RTÉ One and the RTÉ Player at 8:30pm.
Fair City airs on RTÉ One and the RTÉ Player on Sundays, Tuesdays, Thursdays, and Fridays.
