The RHOSLC cast are setting the record straight about the rumors surrounding Mary and her church: "I would have never talked about Mary's church if Lisa hadn't brought Cameron into the picture."

Mary says it's "horrible" and "mean" that the women were comparing her to Jen Shah: "Why do I have to be next?"

Lisa Barlow reveals that filming the show with Cameron was the last time she saw him, and Mary Cosby describes his departure from her church as "amicable."

Mary believes Lisa used her "resources" to find "dirt" on her as a way to get back at her for an earlier fight they had had.

"People want to do their dirty deeds in the dark," says Heather Gay of Lisa and Mary's late-night conversation.

Lisa calls Cameron "remarkable," and fights back tears when sharing that "he is no longer with us."

Lisa explains how she was able to compartmentalize her friendships with both Cameron and Mary, and why she ultimately believed Cameron.

The ladies break down what really happened with Mary's "gift exchange."

Heather: "If I go down over the mountains of Vail, it's not gonna be with you bitches."

The details of what went down during and immediately following Jen's arrest are even more shocking than anyone thought: "I felt devastated for [Jen], and devastated for her children."

Jen Shah: "Heather showing up for me at the most traumatic point in my life...I can't put into words how much that meant to me."

Jen was having trouble processing the situation with very limited details: "This thing was so surreal...I think I was in shock."

Jen is still in shock over what happened and wonders if she's "in the Twilight Zone."

Jen questions the manner in which authorities approached her teenage son and nephew: "It was like what you see on T.V."

Jen describes her long-time friendship with Stuart: "I trusted him on a personal level, to be around me and my family...he was there when my dad passed away."

Mary has not spoken to her mom in over 25 years.

Karlyn might be Salt Lake City's toughest food critic according to Jennie: "She'll tell you if your food sucks."

When Jen didn't hear from any of her family members in the days following her arrest, she assumed the worst.

The women react to the spiraling rumors about Mary Cosby while Whitney Rose describes Jennie Nguyen's luncheon as "pho-king crazy."

Mary says what went down at the pho lunch was "bizarre" and "mean," while Heather Gay describes it as "what is wrong with the world."

Heather Gay has a theory about why Mary distanced herself from Whitney: "Whitney was catching wind of...the horrible allegations about [Mary's] church."

Mary Cosby is still unsure about whether or not she believes Jen's side of the story: "It doesn’t make sense."

When confronted by Jennie about her comments about Jen Shah, Mary suggests Jennie "take that energy and use it to tell [her] husband she doesn't want a sister wife."

Lisa gets emotional when sharing the details of a phone call that she got from Jen while in the car with her kids: "She said some horrible things to me."

Lisa Barlow accuses Meredith of "talking out of both sides of her mouth" when it comes to Jen.

Despite Meredith's discomfort with Jen Shah's arrival, Jennie's intentions for the group were good: "Let's hear Jen's side...be open-minded."

Tensions between old and new friends escalate as the women struggle to find a path forward amidst the group's mounting drama.

Heather wonders if Lisa Barlow influenced Jennie's decision to return the boots Mary gave her, while Meredith Marks reveals that Jennie came to her for advice about what to do.

"They were things in my closet that I didn't want," says Mary, while Jennie Nguyen says she found Mary Cosby's regift "insulting".

"If [Whitney] had come in a bad outfit, I would have really been mad," says Mary of what she describes as an "unkept" and "undone" event.

Whitney becomes emotional while describing Heather's struggles and successes: "She is a superhero cloaked as a housewife."

Jen is emotional as she describes her mom's pleas for Jen's attorneys to let her "trade places with Jen."

Heather Gay dissects Meredith's intent: "I felt like it was a warning shot to Lisa."

"I felt that Meredith was treating me badly to protect Mary [Cosby]” says Lisa, and Heather Gay adds that she "couldn't believe" that Lisa and Meredith were allowing this wedge to form between them.

"Money and sex… those are the things that people get divorced over," says Whitney, who admits that she was worried about the risk involved in Justin investing in her business.

Lisa reveals that Jack wants to go to either Miami or Duke for college, adding that she will "personally be there to manage moving in."

New suspicions circulate as the ladies start to question the circumstances around Jen's arrest.

"This is my life," says Jen Shah, adding that it's "not okay" if Lisa Barlow knew but wouldn't say anything about Meredith Marks' involvement in her arrest.

Mary Cosby thinks Meredith Marks should have been "livid" when Whitney Rose gave Seth a boob cake on his birthday.

"Are you guys setting me up?" jokes Heather, and Lisa Barlow reveals she only took the bus because John told her she "couldn't leave Jennie [Nguyen]."

"All signs are pointing to them knowing something," says Heather Gay, who reveals that the plan to meet at Beauty Lab that morning had only been decided a few hours earlier.

Meredith opens up about why she couldn't be Jen Shah's friend, saying she "had to be able to have some level of trust, and I didn't."

"It's a process," says Jen, who explains that both she and Coach Shah have had a lot of "awakenings" throughout the experience.

While the husbands had good intentions with the Zion trip, the ladies had mixed feelings: "I was not excited."

Meredith confirms that her P.I. looked into all of her cast mates, but denies any involvement in Jen Shah's legal situation.

"It's one thing when it gets physical and you're on ground...we were going 80 mph down the freeway!" says Whitney Rose, who adds that she and a producer had to physically restrain Lisa and Jen.

After Heather Gay raised her suspicions about Meredith, Jen won't stop until she gets the truth: "It's a very simple question: did you do it or not?"

"Nobody is trying to take your Facetune membership, honey" Says Jen, while Meredith maintains that she "never directed anyone to investigate specifically Jen."

Jen Shah laughs and says she was ready to "get popcorn" when she found out: "Let's go around the table, like what did you find out?!"

When asked why she wasn't on the bus with the other women, Mary explains she "doesn't have a good taste for busses."

When Jen Shah calls Jennie out for telling her about Meredith's P.I., Jennie emphasizes that she "did not say" Meredith was specifically investigating Jen.

Mary: "This lady is saying 'you're coming from a good place'...I thought that was amazing."

Meredith Marks says the ceremony "felt great" in the moment, but "little did I know what I was about to sit down to at dinner."

Mary Cosby explains her reaction to the Club Zion stripper pole: "I don't like stripper poles. They seem like they are full of vaseline."

Jen says Meredith being an informant "initially sounded so ridiculous" until Meredith started "insinuating that she had something to do with it."

Mary Cosby describes the ladies as being "lit" and that they "begged me to take them to Vegas in the ATV."

Mary Cosby reveals which one of her "enemies" was at Club Zion, and explains why she "left Meredith on the dance floor."

Meredith reveals that Lisa Barlow came into her room at 3:00 AM to tell her that the ladies were questioning if her father’s memorial was real.

"Sounds likely," laughs Jen Shah, who reveals that she had the first aid kit because she broke her toe during the Red Earth ceremony.

The explosive confrontation between the women was a long time coming: "I wanted them to say what they had been holding back for so long."

While Meredith and Jen Shah seem to make up and hug it out in Zion, Meredith adds that she will have "a lot less compassion" for Jen if she "turns out to be guilty."
