First Kourtney noticed things going missing, like an iPad. Then, large sums of money started disappearing from Kourtney and Scott’s wallets. And it turns out it was an inside job.
"This lady stole $700 out of my wallet, then she stole $4,500 out of Scott's," Kourtney told Khloé in the episode. "Then my security, who's here today, just said he's seen her two times with her flashlight on in the office."
"She's never coming here again."
Although, it turns out that at that very moment, the culprit was still in the house. Kourtney, Khloe and her assistant ran downstairs to confront the girl, but by the time they got there she’d jumped in her car and sped off.
To make matters worse, according to intel from Kourtney's informant, the woman had "also hacked everything." Including Kourtney’s phone.
"We need to change the iTunes password, right now," Kourtney told her assistant. "We need to debug the house and I want to take every device and unconnect it from my phone."
Luckily, Kourtney saw the whole experience as a lesson.
"I obviously can't change what happened, but like anything in life, I believe that this is a big learning lesson … I just want to start fresh and get this bad energy out," said Kourt.
"And next time, we've learned a huge lesson," she told her assistant, who she instructed never let anyone "step foot" in her house without providing their "social, name and address".
