Bill wakes Brooke on his sofa. Taylor arrives and tells Bill she saw Katie but doesn't know where she's staying. She mentions post-partum depression. Bill doesn't care about the fancy labels, he says Katie needs to be there to work on the problems. Taylor tells him she's concerned about the amount of time he's spending alone with Brooke - he has to be careful. Brooke appears and asks what on earth she's saying to Bill. Taylor explains that Katie has an agenda - she thinks someone needs to take her place. Bill advises Taylor to tell Katie to come home. Brooke adds, "And don't you dare tell her to race home to save her husband from me." Taylor accuses Brooke of talking to Bill like they're a couple and tells her to leave him alone. Brooke says she didn't steal Ridge from her, and she's not about to steal her sister's husband. She tells Taylor she needs to examine herself. Taylor insists that something is happening between them. Brooke denies it. They argue. Taylor says she's seen it all before - Brooke's like an animal ready to pounce. Brooke smacks her.
