Brooke (Katherine Kelly Lang) now knows the truth about her sister, Katie (Heather Tom) and former husband, Ridge (Thorsten Kaye), and she isn't hesitant to lt the claws come out as she fights for her man on The Bold and the Beautiful.

Brooke Learns the Truth About Ridge and Katie

After she realized Katie wasn't lying about the connection between herself and Ridge, Brooke became extremely upset and believed that this was a revenge scheme that is being forced on her in order to make her truly pay for her role in destroying Katie's marriage to Bill (Don Diamont). Because she is convinced of this, she will lash out at Katie in extreme ways on the Tuesday, March 11 episode.

"You're angry and you're acting out, you're not doing this because you love Ridge, you're doing this to get back at me!" Brooke insisted in a preview clip for the episode.

Ally Tries To Fire Wyatt

Katie will maintain that she didn't want to hurt her sister and truly never planned to fal in love with Ridge, but her words will only enrage Broke further, forcing her to become even nastier as she tries to convince her sister that this isn't what she really wants.

"Ridge is not going to leave me and you are crazy to even think that he will," Brooke said. "Ridge will never be satisfied with you."

Her words are likely not going to rattle Katie however, and the relationship the sisters share is going to once again be on shaky ground, despite having gotten back to a somewhat more decent place recently.

Meanwhile, Ally's (Ashlyn Pearce) attempts to destroy Wyatt (Darin Brooks) continue to be unsuccessful, as she will be shot down in her attempts to keep him from showcasing Stephanie's jewelry as a part of the newest Hope for the Future line.

"You have to respect our decisions and you have to respect Wyatt's," Eric (John McCook) said to his granddaughter in the clip. "And his relationship with Hope."

The fact that she can't seem to win the battle will continue to enrage Ally as she tries to think of a new way to get Wyatt out of the business.

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