'The Bold and the Beautiful' spoilers, plot news: Steffy will fight Quinn over a forbidden romance

The next episode of "The Bold and the Beautiful" will have Steffy (Jacqueline MacInnes Wood) and Quinn (Rena Sofer) getting into a tiff after Steffy catches her grandfather kissing Sophie.
There have been reports suggesting that Quinn will try to convince Steffy that her relationship with Eric (John McCook) had nothing to do with her. However, Steffy is pretty sure that Quinn will only get into a relationship if there was something in it for her. She's not convinced about this newfound romance between Quinn and her grandfather, and she hopefully wants it done before anything terrible can happen to Eric. Quinn pulled the very same stunt on Liam (Scott Clifton), and Steffy has not forgotten.
Speaking of Liam, he believes he spotted Quinn in Monte Carlo, and he's trying to convince Wyatt (Darin Brooks) that what he saw was real. Little do the two know that Steffy and Quinn are fighting about the very same thing outside. Apparently, finding the girls will fully convince Wyatt that Liam was speaking the truth.
In the meantime, Ridge (Thorsten Kaye) will confess his feelings to Brooke (Katherine Kelly Lang), and he will reveal that his marriage with Caroline (Linsey Godfrey) is over. Caroline will then be free to start anew with Thomas (Pierson Fode), and Ridge has the time to reconnect with Brooke. Though the two are friends, speculations have the audience believe that the relationship will turn into something more than that. This only bodes bad news for Bill (Don Diamont) as he is in current pursuit of Brooke.
Will Quinn's affair lead to trouble for the marriage of Steffy and Wyatt?
"The Bold and the Beautiful" is setting itself up for some complicated love stories, and soap opera fans will go crazy over it.
