TV Guide reports that on Thursday’s episode of the “Bold and the Beautiful,” Wyatt and Steffy agree to tap a VIP as a guest speaker at the Spencer Summmit. Meanwhile, Brooke shocks her sister when she comes to Katie’s aid.

The show’s official YouTube channel posted a preview video for the July 21 episode. It features multiple scenes with Katie, Brooke, Bill, Wyatt and Quinn.

Brooke opens the clip as she reprimands Bill for taking his son away from Katie. “Keeping Will from his mother is wrong and I’m not going to let you do it,” Brooke says. “I won’t allow it.” Katie, for her part, asks Bill, “What have you done with him? Where is my son?” Brooke also assures her sister that they’re in this together. “I’m here because I am determined to fix this,” Brooke promises.

Elsewhere, Wyatt is incredulous about her mum’s latest stunt. He confirms, “You snuck into Forrester dressed like a Russian guy?” Quinn tries to make things light and replies, “I wouldn’t have gone very far if I look like myself.” Wyatt comes over to Quinn and tells her, “I love you, but I hate the position that you put me in.”

"The Bold and the Beautiful" recap

In the previous episode, Brooke and Ridge continued to grow closer as they thrash out their respective issues. They talked about Douglas, and Ridge said he was never his to lose. Brooke also brought up Bill, and insisted she didn’t agree with his decision to take Will from Katie. Their discussion turned to Eric, who’s now managing Forrester Creations again. Ridge caught Brooke surprised, however, when he admitted that Thomas and Caroline love each other. Ridge said she looks at Thomas the way she used to look at him. Speaking of Thomas and Caroline, the two bonded with their son. “Our little family,” they mused. However, their warm moment was spoiled when Veronica arrived. Thomas said they’re having dinner together. Before they left, Caroline asked Veronica to take a snapshot of them as a family. Left alone, Caroline stared at the photo and was deep in thought.
