To make things worse, Scheana Shay still harbors a soft spot for her old friend and Ariana's slimy ex-boyfriend, Tom Sandoval. Things get emotional during a group meditation session when Scheana opens up to Tom about not being ready to forgive and forget his actions. Tears flow as they reflect on the demise of their once tight-knit friendship.

Scheana even meets with Lisa Vanderpump and opens up about feeling like she's "going through the stages of grief" with Sandoval. Lisa probes further, asking if Scheana worries about upsetting Ariana by reconnecting with Sandoval. Scheana's response is telling: "It's just hard when I tried to tell her how I'm feeling when it comes to Sandoval. She literally said, 'I don't want to hear about it.'"

In a confessional, Scheana admits feeling shut out by Ariana, lamenting, "I've done everything I can to be ride or die for Ariana, but is it not enough still? I’m afraid to express how I feel because it's not about me. It's never been about me. It's only about her, so I'm struggling with having any conversation with her lately because I feel like I'm not valid in my feelings."

Meanwhile, Ariana frets about losing her place in the friend group if Sandoval is welcomed back with open arms. She shares her concerns, disclosing, "I mean, I'm trying to be compassionate. But I also know that Scheana is very easily walked all over."

"He knows that Scheana is the easiest route to go to try to get people back in his corner," Ariana adds. "And he knows that if he can get Scheana to come around, Lala [Kent] to come around, James [Kennedy], and then Ally [Lewber], then he can ice me out of the friend group."

During a chat with the girls, Scheana emphasizes that she's mourning the loss of her friendship with Sandoval. She admits, "I'm finally, five months later, going through an actual grieving process. Ariana has already grieved the loss of this. Making millions of dollars and living her best f--king life. I'm not there."

Katie Maloney gets riled up after hearing Scheana's perspective, feeling she's not being a good friend to Ariana. Katie expresses her frustration, saying she doesn't have "any sympathy" for Sandoval.

In a confessional, Katie urges Scheana to wake up and see the situation clearly: "I wish Scheana would just wake the f--k up, look at the situation for what it really is," she states. "Sandoval never really gave a f--k about your friendship. Cut ties, move on, be a good friend of Ariana."
