Anzeichen für die Affäre von Sandoval und Raquel, einschließlich schmutzigem Tanzen um 1 Uhr morgens, tauchen in "VPR" auf: 'Wo ist Ariana?'

James then echoed her sentiment, saying, 'I've noticed how much Raquel has been hanging out with the Toms, both of them. So yeah, best of buds these days.'

Later in the episode, Raquel learned that Oliver Saunders, the eldest son of Real Housewives of Beverly Hills star Garcelle Beauvais, was not entirely separated from his wife when they began their fling.

Her costar Lala Kent caught wind of the situation after his wife posted about it on social media, to which Lala, 32, said at her birthday party, 'This bitch sat across from me and goes, 'You're a mistress.' Well, bitch, I wouldn't be so quick to throw daggers at me. I bet your mom's real proud of you, bitch. There's a woman on the other end of this who's suffering.'

Katie then claimed, 'She never thinks about the woman on the other end of it. She never has. She never cares.' She added in a confessional, 'This is Raquel we're talking about, so I don't know why we expect her to make a wise choice.'

She continued to revel in the irony, calling Raquel a 'dumb bitch.' But Sandoval wasn't cool with her saying that.

'You seem like you get a lot of joy out of that,' he said, to which she responded, 'I don't get a lot of joy out of it. It's just funny to me.'

However, Sandoval didn't believe her as he said in a confessional, 'I've seen Katie over the years be a very proactively vindictive person, so she is savoring this like the best piece of wagyu steak that you've ever had.'

Katie wasn't going to let Sandoval off that easy, telling him, 'You get a lot of joy out of Raquel as well, I think.'

'Yeah, cool person,' he responded.

'You go to The Abbey together at one o'clock in the morning,' she told him, to which Sandoval shiftily denied. 'Dude, what the f--- are you saying, dude? Get the f--- out of here, man,' he said.

News eventually broke of Sandoval and Raquel's off-camera affair in early March, and Ariana ended her nine-year relationship with the Tom Tom co-owner shortly after. Both Sandoval and Raquel have issued apologies for their involvement in the affair. All parties will appear on the Vanderpump Rules reunion to speak about the fallout of their affair.

Sandoval also seemingly called out his female VPR costars for being the ones who are driving continual interest in his affair to TMZ, saying, 'The people that are perpetuating it the most are…you know, the squad of it all.'

When asked how Raquel was doing after she entered a 'voluntary facility for mental health counseling' last week, he replied, 'I don't know, man. There's no comment on that one.'

Raquel checked into a program in Arizona — a plan she'd been considering for some time, according to her rep.

'Raquel and her family decided before the relationship was discovered that she would enter a voluntary facility for mental health counseling,' her rep told PEOPLE. 'She was scheduled to go in pre-reunion but decided she wanted to finish her filming commitment. Bravo and production were aware and in support of her journey towards better mental health.'

Her rep confirmed she is not there for 'rehab' but rather a program focused on 'mental health and trauma therapy.'
