The moment of truth has almost arrived.
In PEOPLE’s exclusive clip from Wednesday Vanderpump Rules In the season 10 finale, Ariana Madix reveals to friends Katie Maloney and Scheana Shay how she found out her boyfriend of nine years, Tom Sandoval, was cheating on her with co-star Raquel Leviss.
“I went with Tom to Tom Tom because I had that party. I found a screen recording of them on FaceTime,” Ariana, 37, says of Tom, 40, and Raquel, 28. “It was literally the night before. He was a [Tom] by Schwartz”.
Schwartz’s ex-wife Katie, 36, can’t believe it. “Was Schwartz doing this?” she comments.
From there, Ariana explains that she confronted Raquel directly for answers.
“I called Raquel and started liking her, making her like, tell me what the hell? When did this start?” Ariana continues. “She said, ‘Right after the girls’ trip.’ I said, ‘You mean right after Charlotte died?'”
A flashback then shows Ariana telling her castmates seven months earlier that she has to abandon the trip because her dog Charlotte “isn’t coming back this time.”
Back in her conversation with Katie and Scheana, Ariana explains what Raquel told her.
“She said they kissed,” Ariana says. “Well, later that night when we were out here, I pressed Tom. And he said, well, they actually fell into his car that night. And he didn’t have a key to get in, so he had to . ring the doorbell and I had to let him in.”
This shocked Katie and Scheana, 38. “I’m…no,” says a speechless Katie.
“My emotions were clearly all over the place and he was mad at me. Angry. At me“, concludes Ariana.
In early March, news broke that Ariana and Sandoval broke up after learning of the restaurant owner’s relationship with Raquel. At the time, a source said the couple “had been having issues for a while,” but that his months-long fling with Raquel was “the last straw” for Ariana.
“He’s put up with a lot over the years, but he doesn’t sit back and be disrespected like that,” the source added.
Both Sandoval and Raquel have publicly apologized to Ariana. She, meanwhile, has been spending time with Daniel Wai. They attended Coachella together in April and celebrated their anniversary together in New York City earlier this month.
Watch What Happens live host Andy Cohen promised VPR Fans will see Tom and Raquel experience “retribution” for their affair when the cast reunites for the Season 10 reunion later this month.
“I think what people seem to want is for Tom and Raquel to be — they want to see the showdown between Ariana and all the friends,” Cohen told PEOPLE, adding, “and they’re going to get that.”
