She has sworn to her husband that she is no longer drinking and is moving past her issues involving her sister's feelings for him, but Katie's (Heather Tom) lies have been discovered by Brooke (Katherine Kelly Lang)—and she 's going to be forced to defend herself to her sister on The Bold and the Beautiful.

Bill (Don Diamont) was wondering if he should still be worried about Katie after she swore she wasn't drinking and doesn't know that she has a secret bottle she's been hiding and taking swigs from. After he also saw her seeming to behave by avoiding all of the alcohol at Steffy (Jacqueline MacInnes Wood) and Wyatt's (Darin Brooks) wedding, he started to feel a little better about how she might be coping. However, Brooke knows the truth after she found the bottle—and she is continuing to confront Katie about the huge lie she's trying to sell.

"How long do you think you can keep this lie up?" Brooke says to her in a preview clip for the Tuesday, April 5 episode.

Brooke will once again try to convince Katie to come with her for help at an Alcoholics Anonymous meeting in an attempt to try and save her sister from destroying her marriage to Bill. However, Katie will remain convinced that she can handle what's going on—and that Brooke is trying to force her into getting help because it will reveal the truth to Bill and potentially ruin their romance. Now, playing on Brooke's guilt that she started these problems by confessing she was still in love with Bill, Katie will get her to agree to keep the secret about her drinking from Bill by accusing her of trying to sabotage things by sharing the truth.

"If you say something to Bill, you will sabotage my marriage," Katie says in the clip. "Is that what you want?"

The Bold and the Beautiful airs Monday-Friday at 1:30 p.m. on CBS.
