The season-long "ménage à trois" between Dorit Kemsley, Lisa Vanderpump and Kyle Richards also rears its ugly head.
"I do treat you the same!" Erika says to Teddi. "I'm rude to everybody."
"The way you talk to me is so dismissive," Teddi replies.
In a second, more explosive scene, Teddi tries to "voice [her] opinion," but it's met with another slam from Erika: "Well, Teddi, raise up or get the f-ck out! C'mon, girl."
"Teddi better mind her Ps and Qs," Lisa Rinna interjects while also addressing her "lame" behavior this season.
Erika then turns her sights to Camille Grammer, who asks Erika why she's giving her "attitude."
"I'm not," Erika replies. "I'm stating the facts."
"I want to be really frank here," Vanderpump tells Kyle sternly. "Most of our conversations are about you." Then Dorit says Kyle told her that Lisa tries to "control" Kyle.
"You're exaggerating, Dorit!" Kyle fires back at Dorit. When the latter seems to think her co-star is full of you-know-what, Kyle adds, "It's on camera!"
"There's a competition here," Rinna concludes, "between Lisa and Kyle."
Andy then asks if he can keep the ball gag Camille gave to Dorit and display it in the Bravo Clubhouse.
"You don't know where that's been," Kyle quips.
