The joke started innocently—Jacob’s fiancée teased at dinner, “Imagine if Jacob wasn’t really your son.” Everyone laughed except me, because years ago, during a rough patch in my marriage, I’d secretly doubted his paternity. That old fear resurfaced, so I asked Jacob to take a DNA test. He agreed, and the results confirmed he was 100% my biological son. I felt relieved for the first time in years.
But days later, I got a call from Lila’s mother, Caroline, asking to meet privately. With shaking hands, she confessed that she and I had a one-night encounter decades ago—something I barely remembered. Then she revealed the shocking part: there was a real possibility Jacob and Lila might be half-siblings. She even brought an old photo as proof. My relief turned into dread as the room spun around me.
