Vicki Gunvalson seems to think Satan is behind Brooks Ayers cancer diagnosis controversy and her daughter Briana Culberson says she is ready to kill Ayers if it comes to light that he is indeed lying about his illness.

As People magazine pointed out, things turned even more dramatic for The Real Housewives of Orange County on Monday’s episode.

Gunvalson, who decided to go on a detox retreat to clear her head over the scandal, maintains that she believes that Brooks has cancer and says the ladies’ speculation about the diagnosis comes from the devil.

“When is enough enough?” she asked the camera. “He’s got cancer.”

Daughter Brianna Culberson does not buy into Ayers claim that he has the deadly disease.

In fact, Culberson and her family think there is something weird going on and only decided to stay at the family home during their Orange County vacation because Ayers was away on business. They noted the bad vibes that seem to linger in the house despite his absence.

“It feels heavy and uncomfortable and there’s just kind of a nasty feeling when you walk in the door,” Culberson told her husband, Ryan – who made a comment himself about the “weird musk” left by Ayers’ presence.

Briana later clarified her feelings for the camera: “There is absolutely nothing Brooks can do for me to accept him.”

After several more discussions about the “illness,” Briana made her feelings very clear about what will happen if it turns out he is lying.

“I’ll kill him. I’ll kill him myself,” Briana said. “Well she’s gonna find out … or he’s just going to be ‘cured’ one day.”

As a nurse, Briana told Tamra that some of what Ayers has said about his treatment sounds strange.

On the way to Tamra Judge’s baptism, Gunvalson agains brought up religion, saying the doubt over Ayers claims is demonic.

“The truth is always the truth,” she said during the ride over to the baptism, adding, “Satan loves confusion. This is Satan’s work.”

Despite her certainty that Ayers is telling the truth, the women seemed dumbfounded over Gunvalson’s passionate defense of Ayers.

Shannon Beador, who seems to be the most worried, said, “The possibility that I’m being duped by Vicki is crushing to me.”

She then added, “Vicki Gunvalson might not be as good of a friend as I thought.”
