“The twins are biologically related to both parents, of course… but genetically, the boy carries markers that indicate something called chimerism.”
Nobody understood.
Except Arthur.
I saw it immediately in his eyes.
He knew exactly what that word meant.
The doctor explained carefully.
“In rare cases, a person can absorb a fraternal twin while still in the womb. That means parts of their body carry different DNA. It’s possible for reproductive cells to carry DNA different from the DNA found in blood samples.”
The room became deadly quiet.
Arthur sat down slowly.
His mother whispered,
“No…”
The doctor continued,
“This means the DNA in your son suggests he inherited genetic material not only from you… but from a second genetic profile your body carries.”
Naomi suddenly started crying.
And then she said the sentence that changed everything.
“Mom… you told us the twin died before birth.”
Mrs. Rachel looked like she might faint.
I stared at her.
“What twin?”
Arthur’s hands began shaking violently.
His mother covered her mouth.
“There wasn’t supposed to be another baby…”
—
That night, after everyone left, Arthur finally told me the truth.
When he was sixteen years old, he overheard his parents arguing.
His father accused his mother of hiding something about Arthur’s birth.
Years later, after his father died, Arthur found old medical records hidden in the attic.
He learned that his mother had originally been pregnant with twins.
But only one baby was officially born.
The other had supposedly “died” during pregnancy.
Except the records didn’t fully match.
There had been another delivery.
Another infant.
A boy.
Alive.
I stared at him in disbelief.
“What happened to him?”
