'The Bold and the Beautiful' spoilers for Sept. 30: Steffy cat fights with Quinn; Liam still in love with Steffy

"The Bold and the Beautiful" is closing the week of Sept. 26 with a bang. After everything that has happened to Eric (John McCook), Steffy will spiral out of control.
Spoilers for Friday, Sept. 30 episode reveal that Steffy will be unleashing the dragon in her to Quinn (Rena Sofer). She has had it with Quinn (Rena Sofer) and this time, she's not letting her go without a fight. Eric (John McCook) fainted while in a confrontation with the Forrester bunch and Steffy is putting the blame on his lover.
She had always believed that Quinn brings nothing to the table but trouble and suffering. When Eric collapsed to the ground, she knew that Quinn's bad luck charm has been activated. Steffy will get fed up with the situation and will attack Quinn.
This isn't the first time that Steffy has attacked Quinn physically and verbally, but reports say that this will be the gravest and most explosive fight that the two will ever get in. Steffy is in rage and she is no longer acknowledging the fact that she's tearing down her mother-in-law.
Even though Wyatt (Darin Brooks) tried standing up for her mother this time, the situation did not change and Steffy is even all the more riled up. Steffy will tell Quinn that her grandfather would have been okay if it weren't for her existence in his life.
Quinn may have been a big menace throughout the seasons but she did try changing her ways and only Eric saw it. She truly loves Eric but no one will believe her. Now, she will start to doubt her own feelings too after Eric got hospitalized. She knows for herself that she is the source of Eric's trouble and increased stress level.
Meanwhile, spoilers reveal that Liam (Scott Clifton) will continue to side with Steffy regarding Quinn. He too believes that she's nothing but a bad omen. Aside from that, he will continue to remind Steffy that he is still in love with her and looks forward to having a future with her.
"The Bold and the Beautiful" airs from Monday to Friday at 1:30 p.m. on CBS.
