Last week on "The Young and the Restless," a security guard arrived at the shack and found Kelly dead. 

Meanwhile, Neil was at the ranch with Victor. Neil told him that he's worried about Nikki and that maybe it's not such a good idea for her to be at the party.

Nikki arrived and told them that she just wanted to get some clothes. Neil tried to convince her not to go to the party because things might get ugly there.

Victor got a call from the guard who told him that Kelly is dead and Jack escaped. The guard promised to bring him back, and Victor told him to make that a priority. Victor joined Nikki and Neil, and Nikki insisted that she was going to the party to support the family. 

Nick visited Cassie's grave, and he told her that she's getting a brother or a sister. Sharon arrived and offered to come back when he's done visiting their daughter, but he said that she would have liked it if they visited her together. Dylan watched the two of them. 

At Crimson Lights, Dylan told Sharon that he followed her to the cemetery. She told him about Yack inviting her to the party, and he offered to go with her. 

At the club, Neil walked in with Gwen, and this stunned everyone. Hilary went over to Gwen and told her that Neil has not been himself. Gwen retorted that she couldn't care less and told Hilary that she and Devon disgusted her. Across the room, Nick told his family that he and Sage are having a baby. 

Yack called everyone to talk about the merger, and said that he is funding a pediatric wing to honor the memory of Cassie.
