The two-part season finale ofKeeping Up with the Kardashianswill take fans inside the cheating scandal that tore famous friendships apart.
“Tristan and Jordyn were all over each other last night,” family friendLarsa Pippencan be heard saying as Khloé, 34, wipes away her tears.
“We just need to figure out what the whole full story is,”Kris Jennerinsists.
But according toKim Kardashian West, they have all the confirmation they need. “Tristan admitted it!” she exclaims.
As for Kylie? She can hardly believe the betrayal. “I’m just like, ‘What were you thinking?’ ” she says in the clip.
And Khloé is equally blindsided. “I knew who he was — I never in a million years thought that’s who she was,” she tells her sister.
“It just sucks it has to be so public,” she adds, crying.
On Twitter, Khloé addressed the upcoming episode and warned fans that she wouldn’t be live-tweeting as usual.
“Well needless to say I won’t be live chatting next week,” she wrote. “Sorry guys.”

In the wake of the scandal, Woodsmoved out of Kylie’s houseand remains largely estranged from the family. A source told PEOPLE last week that the former best friends are now “friendly, but it seems they will never be as close again as they were.”
“It’s Kylie’s choice to have some contact with Jordyn,” said the source. “She understands that it’s still all very sensitive and hurtful for Khloé, but she has the most amazing memories of her friendship with Jordyn. She’s still very surprised at what happened. Kylie always considered Jordyn to be very loyal and respectful.”
