It's decision time for Cristiano in Thursday's Fair City as Deegan questions him about Will's allegation.
Will had earlier said to Cristiano: "I need you to tell John Deegan that it was you that hit me."
Later, in the interview room in Carrigstown Garda Station, Deegan says to Cristiano: "Mr Casey alleges that on or around the 20th October you assaulted him, causing him an injury to his leg. Have you anything to add?"
