"The Bold and the Beautiful" recap

The previous “B&B” episodes have shown the chaotic relationships of Liam, Steffy, Wyatt and Quinn. On Wednesday, Steffy informed Bill and Kate that Liam doesn’t know yet that she is married with Wyatt. The couple agreed that it would be too much for Liam to take right now, and volunteered to stay with Liam while Steffy went home to Wyatt. Bill and Katie recounted what happened with Liam. Bill wants his son to have his head examined. He also revealed to Liam that the police are doing a manhunt for Quinn. Liam reiterated that he owes a lot from Wyatt, who gave him his life back. While he turned in to sleep, Katie and Bill talked about the impending issue – how Liam would react when he learns that Steffy is married to his brother. Meanwhile, Wyatt urged Steffy to come clean to Liam. Steffy, however, felt conflicted as she remembered her romantic times with Liam.
