TV Guide reports that on Tuesday’s episode of the “Bold and the Beautiful,” Bill prepares a surprise for Brooke, and offers her two possibilities about their life ahead. Meanwhile, Vivienne warns Nicole to be wary of Sasha’s motives about Zende.

The show’s official YouTube channel posted a preview video for the June 21 episode. It features multiple scenes with Steffy, Bill, Nicole, Sasha, Zende and Liam.

On the first scene, Steffy is not happy to see Bill walk into her office to talk to her. “Call and make an appointment,” she says without even looking at him. “But be advised I’m not going to let Pam give you one. You already made your point.” In another part of the video, she warns Bill, “Stop playing favourites with your sons.”

Meanwhile, Nicole continues to have a heart-to-heart discussion with her mom. She wonders to Vivienne, “Even though I don’t trust her, shouldn’t I trust Zende?”

Sasha also figures in the clip as she tells Zende, “The chances you gave me, the good you did for me Zende – I just want to do something good for you.” Liam wraps the trailer as he ponders out loud, “Maybe marriage is that big, that worthy of respect.”

"The Bold and the Beautiful" recap

In the previous episode, Liam found Bill’s secret room and before he could think any further, Alison covered up for Bill. She said it’s there because Bill is fond of napping, and claimed that the earring Liam found was Katie’s. Meanwhile, Bill was having a fun family moment with Katie and Will. They talked about commitment to the family. Bill then received a call from Alison, who told him about Liam’s discovery. Later, when Liam confronted him, Bill had the same story as Alison – what he found was a napping room, and the earring belonged to Katie. Liam seemed to buy this excuse – he told his dad that he won’t pursue Steffy because of Bill’s example of a man’s integrity.
