As he intends to make Mr Thorne pay.
After Peter and Carla find out what Mr Thorne did, Peter angrily demands an apology and declares that he’s going to put a stop to his abuse of power.
Finding Mr Thorne in a restaurant, Peter is wound up by him and losing his temper punches Mr Thorne. After being arrested on suspicion of assault, Peter is later charged with assault at the police station.
On behalf of Peter, Carla tries to make amends with Mr Thorne but she is shocked when he asks her to dinner. She reluctantly gives him her number on the basis that he will call her about dropping the charges against Peter.
Meanwhile, Mr Thorne offers to drop the charges against Peter and retire with immediate effect if, in return, he withdraws his complaint with the hospital.
When Peter returns home, Carla accidentally leaves her phone behind and Peter is horrified to read a message from Mr Thorne telling her he looks forward to their dinner.
After telling Carla that he intends to make Mr Thorne pay, Peter calls the Gazette and asks them to run an article about his unethical medical practices.
But when he asks Aggie to dig through the NHS records and provide him with any information which might incriminate Mr Thorne, she explains that she can’t afford to risk her job. Will she decide to help?
