They were mentioned once. Sounds like you're obsessing over it more than the showI hear that. The whole kids having to be named at the funeral was unnecessary. I know Kris was good friends with Nicole. Keep it at that. They almost were mentioned as much as OJs kids.
Which also brings up, if OJ did the killings, he straight up knew his kids were in the house sleeping with the door opened. It's one thing to kill your wife and another to potentially have your kids discover the bodies.
