The police found a ring with Lewis' name etched on it inside Linda McChubs' purse, who was dead. Lewis was in fact her boyfriend and said that he was sure about Liam McChubs (Linda's brother) being the culprit, as he said Liam hated her. He was proven innocent when Zack Clewn was convicted for the murder. Lewis was at Zack's trial and thanked the police for their job and finding the real killer.
The day after that, Alan Smith suggested seeing if Lewis was alright and the team helped him finding a ring that Linda had bought him. In fact, the ring was fake and cheap, but Lewis was happy to know that she kept all of her mementoes with him in a chest.
