Devious schemes and dirty games come to play on the upcoming episode of “The Bold and Beautiful” (“B&B”). On Tuesday, Steffy (Jacqueline MacInnes Wood) remains confident that she’s fully capable of handling Forrester Creations as its new CEO, and no one, not even Quinn (Rena Sofer) can outmaneuver her.

Meanwhile, she’s unaware that Wyatt (Darin Brooks) is still determined to steal her back. With Eric (John McCook) on his side, he’s given a huge boost – everybody knows how Steffy respects her grandfather’s opinions. Other “The Bold and the Beautiful” characters who will figure prominently on the Dec. 20 installment include Liam (Scott Clifton), Ridge (Thorsten Kaye), Rick (Jacob Young), Bill (Don Diamont) and Brooke (Katherine Kelly Lang).

TV Guide reports that on Tuesday’s episode of “B&B,” Ridge and Rick get extremely concerned about Steffy, whom they reckon won’t be able to keep up with Quinn’s manipulations. Wyatt, on the other hand, finds out that he has an influential supporter.

The show’s official YouTube channel posted a preview video for the Dec. 20 episode. [Watch below.] It features multiple scenes with Steffy, Liam, Bill and Quinn.

Steffy opens the clip as she explains the benefits of her being in charge of Forrester Creations. “By pooling my shares with granddad, we can have a lock on the company and we can keep Quinn in check,” she says.

Speaking of Quinn, she assures Wyatt, “With Eric on your side, I don’t think Liam would be with Steffy much longer.” Elsewhere, Steffy cuddles up to Liam and tells him, “This is our first holiday back together, and so many more.” He, on the other hand, doubts that Quinn has changed, “and she never will,” he adds. Meanwhile, Bill expresses that he’s not giving up on Brooke.

"The Bold and the Beautiful" recap

On Monday, Katie shared with Brooke the video she took of Quinn talking to Liam. Brooke agreed that it appeared Quinn threatened Liam. Katie vowed to keep an eye of things before throwing any accusations. She planned to let Quinn think she’s her champion but will always keep in mind how dangerous she is. Katie and Brooke agreed to free Eric from Quinn.

Elsewhere, Quinn tried the outdoor shower she had made – she took off her clothes and stepped into the shower. Ridge walked in and saw Quinn’s naked body. She teased him, asking if he doesn’t like what he sees. He accused her of using sex to control Eric, but she insisted that she’s not devious anymore. She walked out of the shower and into the house, still completely nude. Later, Ridge was talking to Rick, who noticed that his brother seemed off. Ridge told him about seeing Quinn naked and reckoned that she flirted with him. Ridge said that Quinn may be more unhinged than they give her credit for.
