There's plenty of drama coming up on Sunday's Fair City when Zak finally admits the truth about damaging Charlotte's new car to a fuming Decco.
Coming up on the soap, Zak arrives at the house with Charlotte and has a laugh at Decco's expense when he emerges in a Superman apron.
"What's he doing here?" Decco asks Charlotte angrily.
"You didn't tell me it was fancy dress," Zak jokes.
"One more word, go on, I dare you," warns Decco, before Zak cuts to the chase.
"It was me, driving my dad's van, I hit Charlotte's car," he admits.
"You treated me like a clown," Decco says, while Zak protests: "It wasn't like that."
"Just say sorry," Charlotte orders Zak, who complies and tells Decco: "I'm sorry."
"You will be," Decco shoots back. "When you're trying to explain it to the insurance people. They may even drag the Guards into it."
The smile is well and truly wiped off Zak's face at Decco's threat...
