Tristan Thompson may not use his height to its full potential on the court but when it came time to face the Kardashian sisters in Khloé’s delivery room, those extra inches shielded him from the shade being thrown his way.

In a new clip from the Sunday, November 18, episode of Keeping Up With the Kardashians, Khloé’s sisters, Kim and Kourtney Kardashian, and her best friend Malika Haqq arrive to the hospital and join her in the delivery room.

Although the group initially appears happy, their joy turns incredibly awkward when they spot Thompson, who—within the timeline of the show—had only recently been outed as a cheater.

In one part of the clip, Kim stands behind the Cleveland Cavaliers player and makes a cutting motion against her neck while laughing.

“The vibe in the room is calm. I thought there would be way more tension. As much as I want to go off, I just don’t think it’s the time so I’m going to keep it cute,” she said in a confessional. “I don’t have to have a lot of interaction; I just need to be there for her.”

At one point, Khloé had to tell Tristan and Kim to say hello to each other.

Later on, Khloé explained why she let Tristan in the room despite the heartache he caused her.

“I wanted to have a beautiful birthing experience for myself and for the memories of what I choose to share with True when she’s older,” Khloe tweeted. “I want her to have videos and pictures of her daddy there, holding her etc. I want her to know she is LOVE and my happiness!”

“Babies feel energy! I know this!” she continued. “I chose to put my feelings aside for the birth and to try and have as much positive energy that I could.”
