Arriving in LA with a secret
Jack and his wife Li Finnegan arrived in LA and were happy to meet their son's fiance and their grandson Hayes Finnegan. Finn and his partner Steffy Forrester had no idea that Jack is having a horrible secret about him being Finn's biological father and Sheila Carter being Finn's biological mother. Jack was wondering if he should tell them the truth, but he decided not to reveal that the women who shot Steffy's mom is his son's mother. Jack got nervous when he realized that Steffy and Finn publicly informed the world about their upcoming wedding. Jack's worst nightmare came true when he saw Sheila on the reception. When Steffy and her family saw the infamous villain they were furious and skeptic that Sheila is really Finn's mother, but Jack confirmed that Sheila is telling the truth.
Sheila asked Jack to organize a meeting between her, her son, Finn and her grandson, Hayes. She promised that after that she will be out of LA. Jack, being afraid that Sheila will reveal that they had an affair and he is Finn's biological father agrees and gives her Finn's address. He puts his son in an uncomfortable situation and tells him that Sheila is on her way to his home. Sheila arrives and holds her grandson Hayes in her arms when Steffy, who was supposed to be away on a business trip, enters the house. She is in shock and tells both Jack and Finn off. She argues with Sheila and ends up slapping her. She warns her once again to stay away from Finn and Hayes.
