's tongue may have been swollen from an allergic reaction, but that didn't stop her from spilling the beans to Kyle Richards
about her fractured friendship
with former BFF Lisa Vanderpump
on Monday's The Real Housewives of Beverly Hills
"I used to get morning phone calls," Glanville revealed on a hike with Richards, who has had her share of issues over the years with Vanderpump. "I'm starting to wonder if I was doing her dirty work."
"Planting seeds," Richards said, referring to the times Glanville has taken on those in Vanderpump's radar.
"There's a reason for every phone call, every dinner … Friendships aren't a chess game," Glanville said, recalling Richards's remark at last year's reunion in which she called Vanderpump, 53, "Bobby Fischer." "Every move is so calculated."
Continued Glanville: "She's playing the biggest chess game of them all … She's playing all of us … I want to believe everything's genuine … I wanted to feel like this fancy woman likes me. I was enamored."
But Richards, 45, warned Glanville, "I paid a very big price for being honest. She has punished me. Unless you're kissing Lisa's ass, she doesn't like it."
"I'm not 100 percent prepared to go up against her," Glanville confessed. "She's smarter than all of us."
While Glanville, 40, bonded with Richards, Carlton Gebbia
was still angry with Richards for calling her anti-Semitic
"I lived in South Africa during apartheid … I had African friends and I would get followed home from school and get harassed," a tearful Gebbia told Vanderpump at the 40th anniversary party of her husband's family business. "I don't understand how you can have such hate for another person … It cuts me."
Continued Gebbia, 40, who rescinded Richards's invitation to the red-carpet event: "This is affecting our family name … I couldn't believe I was labeled that … To be accused of something like that is so mind-blowing."
At least one housewife was happy, however: Yolanda Foster, who passed her citizenship test.
"To finally become an American citizen is like I've come home," said Foster, 49, who came running into her husband David's arms waving an American flag after passing the test.
