TV Guide reports that on Friday, Abby will have doubts about her relationship with Stitch despite being newly married. Meanwhile, Victor will announce that he has entered into an unexpected partnership.

The soap posted a teaser video for Jan. 8 on its official YouTube channel. It shows multiple scenes with Adam, Luca, Victor, Jack and Jill.

In the first scene, Adam will be seen talking to Luca. Adam asks, “What do you need my help with?” Luca replies by mentioning the name Marco Anicelli.

The next part of the video will show Victor as he asks Jack, “Who is responsible for Billy’s hopes and dreams being dashed?”

A devastated Jill will be the focus of the last scene. She asks the doctor, “What does this mean? He could still beat this, right? He could still come back to us?”

According to spoilers from Soap She Knows, the doctor will tell Jill that Billy has very little brain activity, and there’s nothing they could do but to wait and hope. The recent update on Billy’s health will leave Victoria wondering if Dr. Neville (Michael E. Knight) was right about his recommendation.

Later, Jack will talk to Jill about certain difficult decisions they need to make. Jill, knowing where the conversation is heading, cries because letting Billy die is not an option. Jack tells her that Billy would not want to go on like that, with his life on a limbo. Jill will react to this negatively, and will accuse Jack that he wants to take Billy off the machines. Victoria cuts in the conversation and says that Billy expressed before that he wouldn’t want to live like that. In the middle of their argument, the doctor appears to tell them a piece of bad news: Billy’s health has deteriorated further and might have to be taken off life-support. Everyone will rush to his room and sees him all bandaged up. Later, Victoria will be seen alone with Billy and tells him that if he loves her, he’ll wake up.
