She feels betrayed by her sister, and blames Brooke for her drinking and marital problems. Elsewhere, Ridge and Caroline’s happy life gets threatened when their secret is on the verge of coming out.

The show’s official YouTube channel posted a preview video for the April 15 episode. It features multiple scenes with Bill, Brooke, Katie, Ridge and Caroline.

Katie opens the scene as she talks to Dr Wolin about Ridge’s secret. “You seem to be taking pleasure in this,” she says. “You’re not planning on blackmailing him, are you?” She goes on, issuing a warning to the doctor. “These accusations are totally unfounded. I’d be careful if I were you,” she cautions.

On the other hand, Katie is unaware that her husband and sister are talking about her. “I know you want to take responsibility for all of your sister’s miseries, but Katie had depression issues for a long time,” Bill says. Brooke replies that Katie’s issues started since Will’s birth.

Caroline appears on the last part of the trailer. “I think we should talk about maybe telling Thomas,” she says.
