Her excessive drinking has caused her one-time boyfriend to still have concern over her wellbeing, but that concern isn't sitting well with Deacon's (Sean Kanan) new girlfriend, Quinn (Rena Sofer)-and Brooke (Katherine Kelly Lang) is about to learn first-hand just how dangerous of a threat Quinn may be to her on The Bold and the Beautiful.

Quinn Worries About Brooke's Affect On Her Relationship

Brooke has taken to drinking to cope with being truly alone for the first time in her life, after her past paramours-Deacon, Bill (Don Diamont) and Ridge (Thorsten Kaye)-all moved on in new romances. And though Deacon is happy with Quinn, he still has concern for Brooke's well-being because she is his daughter's mother. However, his spending time with Brooke isn't sitting well with Quinn, and she went to Brooke's house to confront her and tell her to leave him alone.

However, despite knowing what Quinn is capable of from her past manipulations of others, a very drunken Brooke will fight back-and confirm Quinn's nightmares that she may try and steal Deacon away.

Quinn Confronts Brooke

"If I want to hang out with Deacon, I'm going to hang out with Deacon," Brooke slurs in a preview clip for the Monday, March 2 episode.

Adding to Quinn's fears about the state of her relationship, Deacon won't be thrilled when she arrives back home to find out where she went-and the two could find themselves in the midst of a pretty bad argument as a result-and Quinn will be forced to bring up the fact that Brooke never does the things she does with men unless she plans to seduce them in some way.

"Brooke Logan doesn't get drunk and don a bathing suit and invite some guy to a swim party for no reason," Quinn says in the clip.

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