In the clip, Kourt rages at Kris for cheating on her father Robert Kardashian with soccer player Todd Waterman.
“For some reason you do not give mum the benefit of the doubt, ever, from your childhood and it’s really unfair,” Khloé Kardashian says in an attempt to mediate the situation. “You only remember with Todd or this or that.”
“I don’t sit there and dwell about Todd,” Kourtney insists.
When the scene was filmed, Kourtney was still dating Younes Bendjima, so Kris claims that she has her "own Todd right now.”
“No, I actually don’t. I’m actually not married, and I’m not having an affair,” Kourtney fires back. “You can’t compare one to the other. That’s absolutely not true.”
“I’m just saying sometimes our memories get a little warped by our age,” Khloé says. “Don’t be so hard on your mum.”
But Kourtney doesn’t agree.
“I don’t think it’s even about talking to my mum about it,” she says later. “I think it’s like, we all have different experiences with my mum and I think it’s not something, really, that my mum can fix.”
