After her explosive fight with Dorinda Medley, Sonja was feeling some type of way toward Ramona because she felt Ramona took Dorinda's side. During the argument, Dorinda accused Sonja of cheating on her ex-husband. The two have yet to reconcile, but Sonja felt the need to let Ramona know how she felt -- in the middle of Ramona's holiday party.
"You know everything about me," Sonja said to Ramona during their exchange. "I would never cheat on my husband."
"I'm sure," Ramona replied. "I mean, I wasn't there at the time. We weren't friends then."
"You don't need to be there!" Sonja said as a crowd of curious onlookers began to form around them. "But you know that about me, and I told you. You were the only one that knew. I didn't want the whole world to know anything."
"Sonja, I really wanted to put a lid on it," Ramona said.
"She was accusing me of cheating on my husband!" Sonja replied. "People say things when they're angry," Ramona said, trying to pacify the situation. "She was upset."
"What about me?!" Sonja fired back. "What about saying to Dorinda, 'You're both feeling a loss here, and you don't know the story, Dorinda! You're listening to hearsay!'"
The two went back forth about how Ramona wasn't being loyal to Sonja, which Ramona kept saying was because Sonja was the one being "an absentee friend." They literally got into each others faces -- hands cupped around their mouths -- and yelled. Loudly.
Ramona eventually got serious and told Sonja she was worried about her because she felt she was isolating herself from the group.
"I'm very concerned about your behavior," Ramona tried to tell Sonja, but the comment fell on deaf ears.
Ramona eventually stormed off, telling Dorinda and Luann de Lesseps -- who witnessed the whole ordeal -- that Sonja was "out to lunch." She later revealed to Bravo cams that she knew more about Sonja's marital situation than she cared to share during their argument.
"I know some things that Sonja told me privately, but Sonja always told me that in confidence," Ramona said. "She said, 'Don't ever share that.' So I don't really want to take sides."
