In an exclusive clip of Sunday's episode (below), things don't appear to be getting any better for the troubled 29-year-old.
When tempers flare between Mike and GG's love interest, Omid, during a dinner party at Sammy's home that was meant to be, according to Reza, a chance to rebuild friendships, GG tries to calm things down – at first
"It's not a fight," she says, as Mike and Omid trade threats. "It's not a fight."
But Reza seems to think so: "Who the f–– invited the terrorist because someone is hijacking my peace summit?"
Despite GG's efforts, Omid says he wants to stab someone. Then, for unknown reasons GG decides to pick up a knife.
"I'm the only person who's going to stab someone," she says. "I'm going to get like the sharpest f––ing out of the kitchen." And she does.
"I'm literally worried for everyone's safety right now," Reza says.
"If someone's going to stab someone, it's going to be me," GG says, holding a knife. "I'm going to stab someone."
