She has started the test to see if Bill is really going to be loyal to her, and now the biggest part of Katie’s scheme will take effect. However, it could have big consequences for her when it comes to her future on the Thursday, May 16 episode of “The Bold and the Beautiful.”

Katie (Heather Tom) enlisted Shauna’s (Denise Richards) help for her plot to see if Bill (Don Diamont) really meant it when he declared he was going to stay loyal to her and wanted to marry her again. Because of their history, however, on the CBS soap, which saw their marriage end twice due to his affairs with her sister, Brooke (Katherine Kelly Lang), she decided to test his declaration with a seduction ploy.

Since then, Shauna went to Bill’s house and shared a drink with him, which she spilled on his shirt. After Katie arrived to listen in, she then followed him to his bedroom and suggested that they sleep together before kissing him. Now, she will continue her efforts with Katie just downstairs and hearing everything that’s happening.

However, if Bill refuses it may not be just because of loyalty to Katie—it could be because he figured out the plot himself, and how he reacts to it could determine what is in store for their future.

Meanwhile, those who have been the most supportive of their reuniting will all be worrying about what the plot holds as well.

“Brooke (Katherine Kelly Lang), Donna (Jennifer Gareis) and Justin (Aaron Spears) worry as they await the outcome of Katie’s scheme,” spoilers state.

“The Bold and the Beautiful” airs weekdays at 1:30 p.m. EDT on CBS.
