Carl Radke had to hold himself back on Monday night's Summer House as Kyle Cooke continued to insult Lindsay Hubbard.
Picking back up with the escalating argument at the end of last week's episode, Carl defended his decision not to stand up to his friend and business partner Kyle, 40, after Danielle Olivera challenged him for staying silent.
"I'm not gonna stand for any this bulls---," he told Danielle, 34, and the others in the living room. "No one wants to be here for any of us this s---. It's pathetic. It's all f---ing pathetic."
Carl, 38, added of Kyle: "I'm not gonna argue with him. He's already doing the stupidest s--- of all time."
"So he gets to just run his mouth all the time and no one gets to say anything on it?" Danielle asked.
Danielle then went upstairs to talk to Amanda Batula, whom she'd upset when she called Amanda untrustworthy — but Mya Allen intercepted her. Trying to explain herself, Danielle told Mya after Carl walked past them, "I yelled at him too, saying, 'Why don't you f---ing stand up for her? You say nothing, nothing.'"
However, Carl explained his reasoning for not speaking up, later clarifying in a confessional: "I'm incredibly angry and frustrated. One of your best friends yelling at your girlfriend in that manner is ugly and disrespectful.
"If it wasn't someone like my friend who's my boss, it would be different obviously," he continued. "My instinct's like, 'I'll just beat the f--- out of you. I'll fight you.' That's what old Carl would've done, and I don't want to live like that anymore."
Danielle continued to express her frustration about Carl not defending Lindsay, 36, telling her, "Seeing Carl f---ing sit there while his woman is being beat to death by Kyle. What the f--- is that?"
Lindsay, 36, responded, "Literally you can't say anything. There's nothing you can say."
"What he did was sit there while you got annihilated by Kyle, and that's so f---ed up. I'm so over it," Danielle fired back.
But Lindsay completely understood why Carl didn't say anything.
"Do I wish Carl would say something? Sure. Would it be nice if Carl was like, 'Yo dude, f---ing relax, bro.' Yeah. But I understand that he's still trying to figure out how to communicate his feelings and emotions as a sober person," she explained.
Later in the night though, Carl did apologize to Lindsay for not sticking up for her. "I'm sorry that I didn't speak up or say what I'm supposed to say. I'm not going to fight with someone who's been drinking all day and saying insane, crazy s---. It's just not my style," he shared.
"I get it. I'm not upset with you," Lindsay assured him. Carl then revealed he was holding back for a darker reason: "Kyle doesn't want more from me. I could literally could bury him. F---ing over."
Meanwhile, Kyle was still outside in the backyard screaming about Lindsay, saying, "Dude, let's just talk about the elephant in the room. She's ruining everything.
"She's completely brainwashed my best friend. My wife's crying. It all stems back to Lindsay. Everything stems back to Lindsay," he continued on his rant. "God, good luck to Carl. They're a package deal of chaos."
The Loverboy founder then headed back into the house where his wife was sobbing in bed. As she read aloud her texts with Lindsay that sparked the fight, Kyle had a few more choice words for Lindsay.
"She's a f---ing horrible person, and it makes me sick that my best friend thinks he's going to marry her," he said.
As fans of the Bravo show know, Carl and Lindsay — who had already moved in together — were on the brink of getting engaged. Still, when the episode was filmed, their castmates definitely had reservations about how quickly the relationship had gotten serious.
Paige DeSorbo later asked Danielle if she thought her best friends were moving too fast, to which Danielle responded, "100%. They have a car and she's already been like, 'Hey, this is the kind of ring I like,' and I'm like, 'I think to get engaged right now would be crazy.'"
"Because you live a fairy tale for a first year," costar Ciara Miller said.
"That's what I'm scared of. It's a little too fairy tale-like, and they're playing house, and it feels a little fragile," Danielle explained.
She explained further in a confessional interview: "I'm not used to seeing Lindsay and Carl just isolating themselves. I don't know, it's a new dynamic. They're on this pedestal, and I'm just down here waiting from below like, 'Hey guys, remember me? Still Danielle.'"
Summer House airs Mondays at 9 p.m ET on Bravo.
