TV Guide reports that on Monday’s episode of the “Bold and the Beautiful,” Katie finds Brooke’s personal belonging that is related to Bill, which puts another dent to the sisters’ relationship. Meanwhile, Liam is having a difficult time handling his complicated condition.

The show’s official YouTube channel posted a preview video for the Feb. 15 episode. It features multiple scenes with Quinn, Liam, Brooke and Katie.

On the first scene, Quinn is shown as she caresses Bill’s face and tells him, “Maybe it takes something like this to make you realise how special somebody is.” In another part of the video, while they are lying on bed together, Quinn mistakenly calls Liam with his real name. Liam looks thoughtful and asks, “What did you call me?”

Brooke is focused on a scene as talks to her sister Katie. “I will never act on those feelings,” Brooke says. “Bill is your husband, and I respect that.”

"The Bold and the Beautiful" recap

Last week’s Valentine’s Day themed episode showed two couples sharing an intimate moment with their respective partners. Steffy seemed to finally accept that Liam won’t be coming back, and that their relationship was indeed over. She slept with Wyatt, and after, looked up to the sky and bid Liam goodbye. Elsewhere, Liam and Quinn acted as husband and wife Adam and Eve, and practiced making babies together. Liam still had nagging thoughts that there is somewhere that he needs to be. After, he also looked up to the sky just like what Steffy did.
