A new promo for the Keeping Up With The Kardashians two-part special focusing on Bruce's transition has been released, featuring brief reactions of some of his family members.
Kendall, 19, is the most emotional, with her voice noticeably breaking as she speaks about her father.
He replies: "I'm not going anywhere."
Meanwhile, Kendall's younger sister Kylie, 17, says of her father's transition: "I do want to meet her. When he's ready. When we're both ready."
The whole promo is just soundbites played over home movie footage of the Kardashian-Jenner family.
Former Olympian Bruce, 65, confirmed last month that he is transitioning into a woman. The moment he told his family was filmed by the KUWTK cameras and will air in the US across Sunday, 17 May and Monday, 18 May.
The first promo also reveals stepdaughter Kim Kardashian West saying, "We want to understand his struggle" and stepdaughter Kourtney saying: "I think his biggest concern is he doesn't want to hurt us."
Bruce's ex-wife Kris Jenner also has her say, revealing how she met Bruce on a blind date and it was love at first sight. Her soundbite suggests the two-part special will start with their love story and continue through to present day.
The promo ends with Bruce saying: "I don't think I've ever been as scared in my life as I was to be extraordinarily honest with my kids."
Bruce is father to six kids - Kendall, Kylie and elder children Burt, Cassanda, Brody and Brandon. He is also stepfather to Kim, Kourtney, Khloe and Rob.
During Bruce's transition interview on ABC News, his eldest kids joined him to show their support, while Kendall and Kylie sent a statement saying they loved and supported him. Bruce himself revealed that out of his stepkids, Kim had taken his transition the easiest and was the most comfortable to talk with, while Khloe had taken it the hardest.
As well as the two-part Kardashian special, Bruce has filmed his own E! spinoff solo show which will continue to follow his transition on camera.
