She has already confronted her sister after learning she still had feelings for her husband, and now, Katie (Heather Tom) will set her sights on Bill (Don Diamont) and make sure he does whatever it takes to ensure Brooke (Katherine Kelly Lang) never comes near them again on The Bold and the Beautiful.

Katie Confronts Brooke About Her Feelings For Bill

After kicking Brooke out of Spencer and effectively attacking her sister for what she believes was an attempt to win Bill back for herself, Katie will now go to Bill and remind him that he is married to her and that Brooke is not someone she considers to be a cancer for their relationship.

"You're my husband. I'm her sister. I mean, have a little self-control, think about someone else for a change," she says in a preview clip for the Thursday, Jan. 28 episode.

Katie Is Left Devastated By Brooke & Bill's Betrayal

However, when Bill--who, unbeknownst to Katie, expressed the same feelings as Brooke--tries to talk her down and get her to try and see things from Brooke's perspective, Katie will dig her feet in more than ever and scare Bill with hoe determined she becomes that she won't let Brooke take her life away from her again.

"I will protect what's mine," she says in the clip.

Meanwhile, Brooke will lament to Eric (John McCook) about how she may have screwed things up with Katie for good this time--and she will appear genuinely heartbroken that she could have alienated her sister permanently.

"I really think I've lost her forever," she says in the clip.
