Babe ended up delivering the baby and calling on her ex-husband, Paul, a chopper pilot, to come to the rescue.
He arrived and found Babe in labor and Bianca unconscious.
However, he ran away from Pine Valley when he learned that Jamie and Laurie had shared a passionate kiss.
After working for a while to clear his head, JR returned and surprised his family with a new bride, Babe Carey.
He concocted a scheme to take Babe's son for his sister who had just lost her own.
He drugged Babe and set up the scene and told the story: The copter crashed and Bianca's baby was thrown into the river.
Because Adam was very jealous of Tad's relationship with his son, Adam tried to send JR to boarding school, but Dixie put a halt to it.
By now, he had a half-brother, Jamie, born to Tad and Brooke, soon to be followed by a sister, Colby sired by his father with Liza.
His new companion became the trouble-making newcomer, Kendall Hart, estranged daughter of Erica Kane, but things between them remained platonic because of their ten-year age difference.
JR soon became infatuated with one of his classmates, Laurie Lewis, but her father and Adam did everything they could to break the two apart.
Jamie was doubly surprised to see the young woman with whom he had slept with the previous night.
Despite Adam's loathing for the woman he considered a fortune hunter, and his machinations to break the newlyweds apart, nothing worked.
