Sarah and I grew up inseparable, sharing everything — or so I believed. When she had a baby at sixteen, whispers followed her, but she never revealed who the father was. I never asked. I loved her too much to push.

Her son, Thomas, became part of my life. I babysat him, celebrated his birthdays, and watched him grow. Yet something about him always felt familiar — the way he laughed, the way he tilted his head when thinking. A feeling I couldn’t name.

Then one afternoon, everything shifted. Thomas was playing on the floor when his shirt lifted, revealing a small crescent-shaped birthmark near his waist. I froze. It was identical to the one passed down through my family.
I had it.

So did my brother.

I told myself it was coincidence, but the thought wouldn’t let go. That night, driven by fear and doubt, I sent off a DNA test using a spoon Thomas had used. Weeks later, the results confirmed it: 99.9% match.

Thomas was my nephew. My brother’s child.

The truth shook me. I stayed silent, knowing Sarah had carried this secret for sixteen years. Then one evening, she finally said it herself: “Thomas’s father… is your brother.”

I wanted to be angry, but all I saw was exhaustion and guilt. She hadn’t hidden the truth out of shame — she had done it to protect her child from a storm she once faced alone.
