TV Guide reports that on Monday’s episode of the “Bold and the Beautiful,” Liam gets the opportunity he’s waiting for to steal Steffy away from Wyatt. Meanwhile, Bill pulls out all the stops to confirm the legality of Wyatt and Steffy’s marriage.

The show’s official YouTube channel posted a preview video for the June 13 episode. It features multiple scenes with Thomas, Steffy, Quinn, Wyatt, Reverend Rydell and Liam.

On the first scene, Thomas tells Steffy that she can’t keep denying the way she feels about the recent events. “You can’t keep them bottled up – it’s not good for you,” he cautions her. “If Quinn had never kidnapped Liam, if he hadn’t been away for so long, you would be his wife,” Thomas also says.

In another part of the video, Wyatt implores Reverend Rydell to tell the truth. “I need to know if you filed those papers in your legal capacity as a minister.” Liam wraps the trailer, as he expresses his doubts. “This marriage to Wyatt can’t be legal,” he says.

"The Bold and the Beautiful" recap

Last week, Liam recounted to the police about his run-in with a masked intruder. Liam theorised that the incident may had been connected with his family issues, and he wanted to warn Wyatt. Lt. Baker raised the possibility that Quinn may be involved, but Liam said it couldn’t be her – she does her own dirty work. Elsewhere, Steffy was shocked to learn that Wyatt only found the minister who married them on the Internet. Wyatt defended his move, saying that the reverend was available on short notice. The two then received a call from Liam, who shared the information about the break-in. Liam said he’s on his way to the police station because someone’s in custody. Wyatt said he’ll meet him there.

At the station, Liam and Wyatt looked at the line-up of criminals. Liam identified Reverend Rydell as the masked intruder. Wyatt said he knows him, too. “He married Steffy and me. He’s our minister.”
