It was supposed to be just another glittering Hollywood holiday party—but by morning, it would become the last social event tied to Rob and Michele Reiner’s lives. And one unsettling moment from that night is now impossible to ignore.The Christmas gathering, hosted by Conan O’Brien, took place only hours before the devastating news of the couple’s deaths broke. What once felt like harmless party chatter has since taken on a chilling significance.

According to The Wall Street Journal, the event marked the final social appearance of Rob and Michele Reiner. They arrived that Saturday night with their son, Nick Reiner, at O’Brien’s home, surrounded by familiar faces from the entertainment world.Nick Reiner’s behavior at the party quickly stood out. The 32-year-old, who has struggled with substance abuse issues for more than half his life, began asking fellow guests a series of strange and repetitive questions.At one point, Nick interrupted comedian Bill Hader—whom Rob Reiner had personally introduced him to earlier that evening. He reportedly asked Hader, “What’s your name? What’s your last name? Are you famous?”
