TV Guide reports that on Thursday’s episode of “B&B,” Thomas surprises Liam when he expresses support with regard to Steffy. Meanwhile, Wyatt tries to save his marriage by making serious demands with his mother.

The show’s official YouTube channel posted a preview video for the Aug.18 episode. It features multiple scenes with Quinn, Eric, Wyatt, Steffy, Ridge, Thomas and Liam.

On the first scene, Quinn tells Eric that her triumphant return does not go so well with his family. In another part of the video, Eric claims that Quinn “brings happiness and joy in my life – something I didn’t even know I was missing.”

Meanwhile, Steffy shares with his brother, “Liam and I would be married right now if it wasn’t for Quinn.” This leads Thomas to inform Liam, “I think that you’re the real love of my sister’s life.”

Wyatt wraps the trailer as he lashes at Quinn. “It doesn’t matter what you say,” Wyatt says. “It doesn’t matter how you feel. You cannot move in here.”

"The Bold and the Beautiful" recap

In the previous episode, Wyatt reeled from Steffy’s shocking news about Quinn’s comeback at Forrester Creations. Steffy threatened that there is going to be a price to pay, and Wyatt promised to put Quinn out of their lives once and for all. Meanwhile, Eric surprised Quinn when he arranged something romantic for them at the mansion. The two enjoyed their moment together, from playing the piano and dancing. Quinn was even more shocked when she found a house key in her champagne glass. She happily agreed to move in with him.

Elsewhere, Ridge was brooding over his problem – his dad just kicked him out of the mansion. Steffy arrived and Ridge updated her about Eric’s latest move. Steffy could not believe that her grandfather doesn’t care about anything but Quinn. Steffy called Quinn a deal-breaker and said, “I can’t have that woman in my life.”
