KUWTK two-part finale sneak peek: What we’ll learn about Kylie Jenner BFF

One of the frustrations facing KUWTK viewers: Life in the real world happens weeks, sometimes months, before the reality TV show airs it.

Such as is the case with the cheating scandal that rocked the Kardashian and Jenner clan months ago, when they learned that Kylie Jenner’s best friend Jordyn Woods had canoodled with Tristan Thompson, Khloe Kardashian’s baby daddy, at a party.

However, as People points out, the first episode in the two-part Keeping Up With The Kardashians finale will  show for the first time exactly how the Kardashian and Jenner family learned about the scandal sparked by Jordyn and Tristan making out.

How did Khloe, Kourtney and Kim Kardashian learn about scandal?

During the episode, Khloe, Kourtney, and Kim Kardashian get on a phone conference to figure out the truth about the rumors regarding Tristan.

The sisters at first clearly can’t believe that their sister Kylie’s best friend Jordy, who also is a family friend, would go behind Khloe’s back and canoodle with Thompson.

During the conversation, Kim reveals that her friend Larsa Pippen told her aabout a reporter planning to write a story that Jordyn and Tristan were at his house late at night or early in the morning.

“They said they were like, making out and I immediately didn’t believe it,” admitted Kardashian. “I was like, ‘This can’t be true.’ “

Khloe described her own conversation with Woods as “really weird.”

Jordyn told Kardashian that Tristan was “trying to kiss me” and then said she couldn’t remember if they actually kissed or not.

How Kylie Jenner learns about the ‘f…ing truth’

When Kylie gets added to the conference call with Kim, Kourtney, and Khloe, Jenner is stunned when Khloe reveals the details of her conversation with Jordyn.

"I spoke to Jordyn. She was in between his legs. She said, ‘I can’t remember if we kissed.’ I said, ‘If you are too nervous to tell me something, you can text me. And she said, ‘Okay, I’ll call you in five minutes.’ She hasn’t called me and that was like, 20 minutes ago."

Hearing that, Kylie called it “weird.”

But Khloe was more blunt about the possibility that her baby daddy had cheated on her with Kylie’s BFF.

“I need the f—ing whole truth,” said Kardashian.

Ultimately, the situation will play out on the finale of KUWTK.

Woods has said that her hope is she will be shown in a way that lets her “real” self “shine.” She has previously stated that she and Thompson did not have sex and that kissed her at a party following a lengthy period of drinking at his home.
