In her dressing room, Kathy shared that she was looking forward to seeing her sister on the reunion stage. "I don't like having bad energy with anyone, and I think this is good and healing for Kyle," Kathy said.

She then revealed that she believes that Kyle and Mauricio have been dealing with difficulties in their marriage for several years. 

"[Mauricio] is going one way, she's going one way, and they're both trying to work," she continued. "He's dancing for four months on Dancing with the Stars. Kyle, she's not a compulsive person to just jump and make a decision."

"Kyle didn't decide this in three months. This, for sure, I bet she had been thinking and feeling probably the last three [or] four years," the mom of four added. "I shouldn't say that, but I did."

What to Expect from Kathy Hilton on the RHOBH Season 13 Reunion

After it was revealed that Kyle's older sister would be in attendance for part of the reunion, several cast members began to tease what viewers could expect to see from her.

Annemarie noted that Kathy and Kyle, who went through a period of estrangement after Season 12, had "a lot of important things that they talked about at the reunion" during an interview with Page Six.

She added that those conversations were "very deep and very necessary.”

Crystal, who has long been friends with Kathy, told E! News that "Kathy always brings a lightness and comedic relief that we desperately need."

"And, of course, she surprised us!" she continued. "So yeah, she's awesome."

See what happens when Kathy joins the rest of the ladies by watching Part 3 of The Real Housewives of Beverly Hills Season 13 reunion on Wednesday, March 13 at 8/7c on Bravo. Stream episodes the next day on Peacock
