Sally envisions a future with Liam in "The Bold and the Beautiful"

Marriages begin and end on "The Bold and the Beautiful," and spoilers reveal that it is the case for Liam (Scott Clifton) and Steffy (Jacqueline McInnes Wood).

It seems that what occurred between Liam and Sally (Courtney Hope) when they were trapped underneath all the rubble of what was once the Spectra building triggered the unofficial end of Liam and Steffy's marriage. Fans know that Liam and Sally, thinking that they were going to die that time, shared a kiss.

Liam thought he did the right thing by admitting it to Steffy, who proceeded to rip into him for supposedly betraying her like that, when she would later on commit the same mistake, only worse. Not only will she have cheated on Liam by hooking up with someone, she did it with none other than Bill (Don Diamont). She, along with Bill, have basically managed to cause harm to Liam that will further drive a wedge between his marriage with her and his relationship with his father. This is a secret that is bound to explode sooner or later.

Come Thanksgiving, Steffy and Bill will definitely try their best to hide their actions, with the former evidently struggling to do so. So, supposedly Liam finds out by then, a divorce would not be far off, even though Steffy is seemingly dedicated to Liam for now. The deed has been done and it might be time for the two of them to part ways so she could be with Bill instead. It has been hinted before that their hookup will turn into something more, which could possibly be a relationship for the long run.

Meanwhile, "The Bold and the Beautiful" spoilers for Friday's episode reveal that Steffy's guilt will worsen, especially after what Liam decides to do. She has become quite a mess ever since that hookup, and all she could do for now was to constantly apologize to an unsuspecting Liam. She will apologize for the way she treated him, but he will contend that everything is okay, which just intensifies the guilt she is feeling.

Of course, the last thing she would want to do is to tell Liam what happened. She knows how hard a blow this could be. Instead, she will just talk about regrets and wonder if the two of them can be able to power through this. Liam will assure his wife that it is still possible. He will think that they can get through this and he has an idea of how they could do it.

Previously, Liam got in touch with Carter (Lawrence Saint-Victor). He has a surprise for Steffy and he needs Carter's help to carry it out. It seems that Liam might want to renew his vows to her. It is safe to say that Steffy might be crying her way all throughout the episode.

As for Bill, he will feel that there is hope for a future with Steffy. While she was ashamed of their little romp in the sack, he was more on satisfied. Bill might feel a little guilty deep down, but he can choose to blow past it if it means being with her. Bill is definitely up for more steamy meetings with Steffy.

He will instruct Justin (Aaron D. Spears) to get his yacht, the Stella Maris, ready. Knowing Bill's motives, he definitely would be one to plan an evening with Steffy on the yacht. Then again, he could be arranging for a special romantic night for her and Liam.

"The Bold and the Beautiful" airs Mondays to Fridays at 2:30 p.m. EST on CBS.
