Two "Keeping Up With the Kardashians: About Bruce" episodes air on E! this Sunday and Tuesday night.
The episodes revolve around the Kardashians' reactions to Bruce Jenner's announcement to ABC News' Diane Sawyer about being transgender and his intention to transition to female.
On Tuesday's episode of "About Bruce," Kourtney Kardashian tells her boyfriend Scott Disick and sister Khloe Kardashian that she has been to therapy about the "Bruce thing," noted Headlines & Global News (video below).
Disick adds that he had no idea that Bruce was planning to transition, even after he had his Adam's Apple shaved.
"I just thought he wanted a slimmer neck, I literally never dreamt of thinking that he was going to transition," Disick recalls.
"Don't talk too much about it in front of Mason," Kourtney tells Disick, in reference to their 5-year-old son.
"He's gonna come to an age and he's gonna start asking questions, and he's gonna say, 'Whatever happened to that grandpa I had?'" Disick states.
Kourtney later adds in a solo interview:
I think we are waiting to see what Bruce does before we tell Mason. I definitely don't want him to find out, you know, through someone at school or something like that. I want him to find out through us.
And I think it's just such a great lesson to, you know, teach him not to judge people. It's a great life lesson that, you know, I think I have to make it the most positive that I can.
According to CNN, on Sunday's episode of "About Bruce, " Bruce told his daughters that he would be leaving his Bruce persona in the spring.
Khloe replied, "I don't think it's fair you don't tell us how close this [transitioning] is. We are still your kids."
However, Khloe did give Bruce some "woman-friendly" gifts, and added, "I don't know her taste yet, so I'm trying to find that out."
Kim Kardashian recalled the shock of walking in on Bruce while he was dressed as a woman, while Kendall Jenner says she thought her dad was having an affair after she found his lipstick and makeup.
