On Friday's episode of The Bold and the Beautiful, relationships will all be put to the test.

A preview for the episode heavily features two of the more dramatic couplings on the show, Brooke (Katherine Kelly Lang) and Bill (Don Diamont), and Hope (Kim Matula) and Wyatt (Darin Brooks).

While Hope and Wyatt are abroad, the drama between the two continues as Wyatt tries to convince Hope not to marry his brother Liam (Scott Clifton).

"Don't marry my brother," he told a semi-distraught looking Hope. Earlier on in the clip, Hope was confronting him about the idea that she may be trying to get some sort of revenge on Liam.

In the short clips featuring Brooke and Bill, Brooke is opening up to Bill about how she really and truly feels about him.

"I can't deny my feelings for you anymore," Brooke said to him in the clip. "Now that we're finally together, I can't let you go."

What this could mean for Katie (Heather Tom) though, remains unseen, though in the clip she does reveal that she wants to get over him.

"As hard as it's going to be, I'm going to try to forget how much I still love him," she said.

Poor Katie is going to have even more to deal with if a recent interview Don Diamont did with TV Guide (published by The Seattle Post-Intelligencer), is true...he is going to rub salt in her wounds even further by now proposing marriage to her sister Brooke, who will say yes on the upcoming September 30th episode!

"It won't go over well! And it certainly isn't going to help smooth things over between the Logan sisters," Diamont said. "But, as with everything else in life, Bill doesn't give a s-t what anyone else thinks."

Diamont went on to say how even though fans may not approve of the Bill-Brooke-Katie love triangle, they need to understand why Bill cheated on Katie with her sister in the first place, and how the relationship with Brooke has changed.

"It's not just an affair of passion. Katie has daddy issues and she and Bill had kind of a paternal Svengali thing thing going on..." he said. "She needed the all-powerful Bill Spencer to care for her and tell her she was good enough...With brooke, Bill may have found his soulmate. The audience needs to see that they share a genuine love connection in order to root for them-especially after the mess that's been made."
