There will be a major drama in Genoa City when "The Young and the Restless" airs on Dec. 11-15. The feud between J.T. (Thad Luckinbill) and Billy (Jason Thompson) will worsen, while Victor (Eric Braeden) will discover an anomaly.

J.T. will suddenly return, which will surprise Victoria (Amelia Heinle). She will think that J.T. will be helping Paul (Doug Davidson) with his case against Victor. But Victoria will feel that this is not the only reason why J.T. is back. She will try to get answers from J.T., but she will learn about his personal problems instead. This week, Victoria will also try to find out who leaked the information about the plan of Newman Enterprises to develop Chancellor Park.

Billy and J.T. will cross paths, and things will not be easy between them. Some old issues will come up during their reunion. Because of this, Victoria will need to intervene. On the other hand, Nick (Joshua Morrow) and Nikki (Melody Thomas Scott) will try to prevent Newman Enterprises from destroying GC. But their mission will not be that simple since Victor is ready to start a war with them. Nikki will also have a confession to make that will surprise viewers.

This week, Michael (Christian LeBlanc) will tell Victor that the authorities will be sending someone to meet him about an anomaly. What will Victor learn this time? It appears that it has something to do with Kevin (Greg Rikaart). Kevin will be seen talking on the phone with someone. He will sound tense and worried that Victor will learn the truth about what the culprit did.

Who is Kevin talking to? Reports speculate that it could be Chloe (Elizabeth Hendrickson) since she has caused more trouble behind Victor's back. It could also be Chelsea (Melissa Claire Egan) or Adam, if he is still alive. Whoever is that person, Kevin will warn him or her since he knows what it is like to face the wrath of Victor.

"The Young and the Restless" airs weekdays at 12:30 p.m. on CBS.
