Last week on "General Hospital," Sam visited Sabrina at the Quartermaine's. She revealed what Nina told her, and Sabrina thought that her suspicions of Rosalie were correct. 

Laura walked into Wyndemere as Nikolas was arguing with Sloane on the phone. They talked about business and Laura recalled when his grandfather tried to take over ELQ. She told him about breaking up Luke and Tracy. Nikolas thought that she could do better than Luke, but he gave her his blessing anyway. 

Meanwhile, Lulu joined her father for a drink at the Haunted Star and asked him why he broke Tracy's heart and reunited with her mom. He said that he hates what he had done to Tracy. Dillon stormed in and demanded answers. Luke couldn't say anything, and this made Dillon mad. As Dillon tried to attack him, Lulu shouted at them to stop. Luke told them that everything he said to Tracy the night before was a lie.

Michael gave Jake a tour of ELQ and introduced him to Rosalie. Michael said that he hired Jake to find the mole in the company. Jake headed off to meet his security team, and once he was gone, Rosalie told Michael that hiring Jake could be a costly mistake — he could be a mole for the Cassadines. Michael reassured her that he had Jake vetted. She worried that he was doing the same for all his employees, but Michael told her that he didn't have her investigated because he trusted her. While they were talking, Sam sneaked into ELQ and planted a bug on Rosalie's phone.
