She was initially really supportive of her fiance's decision to go to AA meetings, and even applauded his efforts in helping out a mystery friend from the group, but Quinn (Rena Sofer) will be heartbroken when she realizes Deacon's (Sean Kanan) pal is none other than Brooke (Katherine Kelly Lang) on The Bold and the Beautiful.

Quinn Becomes Suspicious Of Deacon's Friend

After sharing her good news about being hired back at Forrester with Deacon, Quinn smelled some perfume on him, which seemed odd since he had just come from seeing his friend-who she believed was another man. However, when Brooke also shows up in the office and Quinn smells the same perfume on her, her suspicions that Deacon was lying are confirmed-and she will be heartbroken as a result.

"I can't believe you," she says to Deacon in a preview clip for the Wednesday, April 1 episode.

However, as she continues to grill Deacon about this monumental secret, he will make excuses for why he didn't tell Quinn the truth-including reminding her of how she reacted when Brooke tried to forbid the two from getting married.

"I just didn't think she needed you going ballistic on her for no reason at all," he says to Quinn in the clip.

And while Quinn will likely take offense to his comments, she may eventually come around and tell Deacon she forgives him for lying to her-but considering her history, Deacon would be wiser to potentially try and watch both his and Brooke's backs, since Quinn never handles betrayal or people taking away what she wants very well.

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