"The Bold and the Beautiful" recap

On Thursday, Bill went over to Brooke’s house to tell her that Katie overheard him talking on the phone and mentioned Brooke’s name. Bill said Katie exited the party after that. Brooke said that maybe Liam was right – maybe it’s time to come clean with Katie. Surprisingly, Bill agreed. He said they should tell Katie so he can be with Brooke. She then received a call from Liam – Katie’s in a state. Brooke said she’ll rush over there, then told Bill that she’ll tell her sister everything.

Meanwhile, Liam was not exaggerating about Katie – she was absolutely losing it. When Brooke arrived, Katie begged her to tell her there is nothing going on with Bill. “I'm sorry,” Brooke whispered. Katie gasped, “Oh God...you and my husband.”
