The latest episode featured the fall-out from her drinks with old flame Todd Waterman.
Kris' husband Bruce Jenner was still mad about their secret meeting, and in an effort to prove to him and her kids that she wasn't playing away, Kris took a lie detector test.
When Kris was asked, "Would you like to have an affair with Todd?" she answered "No," but the machine went crazy. However, the man administering the test said Kris could have just been having a strong emotional reaction to the question, which made the machine react.
The kids sent the unhappy couple on a mini-vacation to patch things up, and they agreed that they'd work on their relationship.
