Their first battle ended with Sheila suffering from a concussion and figuring out a way to stay at the Forrester Mansion. Now, as the tensions continue to boil between them, both she and Quinn will find themselves locked in another heated confrontation on the Monday, Aug. 28 episode of “The Bold and the Beautiful.”

Sheila (Kimberlin Brown) was livid when she learned that Eric (John McCook) had taken Quinn (Rena Sofer) back after her affair with Ridge (Thorsten Kaye), and went to the mansion to return his watch after learning the news. While there, she and Quinn got into an explosive battle on the CBS soap, which included throwing lamps and nearly any other object they could find at one another. Quinn finally managed to get a decent shot at Sheila’s head, knocking her unconscious. Since then however, Sheila has been staying at the mansion with the newly-reunited couple, first at Eric’s insistence so she could recover, and then through some scheming of her own.

In an attempt to determine if she was improving, Eric sent for James Warwick (Ian Buchanan), who Sheila then blackmailed into making her seem worse than she really was. Now, her invitation has been extended at the mansion, much to Quinn’s chagrin, and she will gloat to James about how he’s helping her.

“That b**** will betray him again and thanks to you, I’m going to be here when she does, and I’m going to take her down,” Sheila says in a preview clip.

However, when James continues to express that he doesn’t want to lie to Eric any longer, Sheila will remind him that she can destroy his life by spilling his huge secret, and will caution him to remember that before he shares the truth with anyone about how she is actually healthy.

“You think long and hard before you say anything,” she says.

Meanwhile, Quinn will once again ask Eric to rescind the offer he made Sheila, because she doesn’t feel safe with her living in the house, since she knows Sheila will do anything she can to break up their marriage and get Eric back for herself. However, Eric will maintain that letting her stay for now is the right call to make, because it prevents her from becoming dangerous.

“We push her out of here too soon, too quickly, it’ll just come back to bite us,” he says in the clip. “I think you understand that.”

However, Quinn will remain determines that the other woman needs to leave, and will once again storm upstairs to confront her. If she overhears Sheila’s threat however, she will realize that the entire situation is being faked, and Sheila is fully recovered from their first battle. With that new information at hand, Quinn will storm in to confront her enemy, and it won’t take long before the two are once again going at it.
