TV Guide reports that on Thursday’s episode of “B&B,” Wyatt compels Steffy to be straightforward with regard to the status of their marriage. Meanwhile, Brooke’s son returns, and he’s not exactly happy about her upcoming wedding with Bill.

The show’s official YouTube channel posted a preview video for the Sept. 15 episode. It features multiple scenes with Steffy, Wyatt, Alison and Bill. On the first scene, Wyatt tells Steffy, “If there really is no way for you to get past this, then I got to know right now.” She replies, “We may be living apart, but I’m still Mrs Spencer.”

Meanwhile, Alison expresses her happiness for Bill’s upcoming wedding. “There is nothing standing in your way,” she gushes. “You can finally make Brooke Logan your wife.” Bill, on the other hand, can’t help but gloat about prevailing over Ridge. “It’s got to be killing Forrester – knowing that his Logan is going to be all mine,” he says.

"The Bold and the Beautiful" recap

In the previous episode, Bill surprised Brooke when he brought in a wedding planner and revealed that they can be married in a couple of days. Brooke was incredulous when he asked her to practice her vows and clean out her desk at Forrester. Speaking of surprises, Eric was taken aback when he saw Pam, Rick, Ridge, Thomas and Steffy at his office. They were there to discuss his engagement with Quinn. They all expressed their disapproval, with Steffy even threatening she won’t set foot in the Forrester mansion anymore as long as Quinn’s there. Eric brushed them all off and confirmed their worst nightmare: he is marrying Quinn and she will be the next Forrester matriarch. Elsewhere, Wyatt headed over the mansion to confront his mum. Wyatt cringed when Quinn referred to herself as Mrs Eric Forrester. He told her that if his marriage ends, it’s all on her.

Meanwhile, Brooke and Ridge talked about her upcoming wedding. He’s still upset with the whole plan, but Brooke told him it’s the only way everybody would win. He called Brooke his Logan again and pulled her onto his lap. Ridge said that Bill doesn’t understand her the way he does. At that point, their son appeared and announced, “I’m home.”
