"When I got pregnant with North, I had no idea if Kanye and I were going to end up together," Kim says, "I was like, 'We can break up, but let me just at least have some sperm, so I can have another one, so I could have siblings.'"
"So Scott just texts me that he wants to have another baby ... with Kourtney," Kim says, "I think he just wants one more, and she wants one more."
"She definitely wants more kids," Larsa muses. "If they both want to have more kids, why not have them together? Their kids are gorgeous."
"I mean, it's like, Scott has a girlfriend, Kourtney has a boyfriend, we get it," Kim says. "They don't even have to have sex. It could be IVF."
"It's just so much easier to have the same dad," Larsa agrees.
The mother of North West then pulls out her phone to send a group email to her family about the situation.
"I have to tell the rest of the family to be like, 'Guys, should we encourage this?' How cute will that be? They have to have another baby!"
Kim is then shown in a confessional saying: "I think I do hold onto this hope of Kourtney and Scott because I'm so used to them being together."
The teaser cuts back to Kim talking with Larsa, as she admits: "When I got pregnant with North, I had no idea if Kanye and I were going to end up together. I was like, 'We can break up, but let me just at least have some sperm, so I can have another one, so I could have siblings.'"
However, there was one small snafu in Kim's plot. While talking to Larsa, Kim gets a call from her sister Khloe, who reveals that Kourtney was accidentally included on the email she sent about conspiring to get Kourtney pregnant again by her ex.
All Kim can say is, "oh my god."
