Deacon Sharpe (Sean Kanan) has made his intentions to win Brooke (Katherine Kelly Lang) back perfectly clear since arriving back in L.A., but he could be in for some major heartbreak on The Bold and the Beautiful.

Deacon Seeks An Answer From Brooke About A Future Together

After Brooke called him over to her house to tell him that they were going to become grandparents, Deacon once again told Brooke how much he wanted to be with her again, and repeated his desire to marry her if she would just say yes. However, their potential for a reunion was then interrupted by Bill (Don Diamont)--who heard Ridge (Thorsten Kaye) was designing again--meaning Brooke no longer had reasons to be mad at him and frees them to finally say their own vows.

Now, Brooke will be forced to make a decision between her two former loves-and someone's heart will be broken. Despite the several times Bill has proven himself to be untrustworthy and someone she can't depend on, Brooke may choose him anyway-though Deacon will still put up a fight to win over the woman he loves.

Deacon & Quinn Try Seducing Brooke & Bill

"If you could forgive him, you could forgive me. Please, don't marry him," he begs her in a preview clip for the Monday, September 29 episode.

Despite his begging however, he may still find himself the loser in the race for Brooke's heart.

Meanwhile, Quinn (Rena Sofer) is still trying to convince Wyatt (Darin Brooks) to forgive her for her actions in Paris, but she may suddenly find herself not caring very much for her new daughter-in-law, Hope (Kim Matula) when she learns that Wyatt was given an ultimatum to cut his mother out of his life for good.

"I will never allow anyone to forbid me from seeing my son," Quinn says to him in the clip.

The Bold and the Beautiful airs Monday-Friday at 1:30 p.m. on CBS.
