The digital hum of the ultrasound monitor sounded like a ticking time bomb in the sudden, suffocating silence of the examination room. Diego stood by the door, his chest puffed out with the arrogant authority of a man who believed he had finally caught his prey, while Paola kept a tight, venomous grip on his arm, her eyes filled with a smug, triumphant malice.

“Go ahead, Doctor,” Diego sneered, crossing his arms over his tailored jacket. “Tell her. Tell my unfaithful wife exactly how many months she is, so we can finally take these numbers to the family court in Polanco.”

Dr. Salinas didn’t flinch. She slowly laid the transducer down, took off her glasses, and looked at Diego with a look of profound, surgical detachment that made Paola’s triumphant smile instantly freeze.

“Mr. Diego,” Dr. Salinas said, her voice dropping into a flat, sub-zero register. “The gestational sac is exactly nine weeks along. The biological timeline matches your wife’s ovulation perfectly, falling precisely two weeks before your scheduled vasectomy. But that isn’t the reason I asked you to look at this screen.”

Dr. Salinas tapped the monitor, zooming in on the complex corporate and genetic markers flashing on the high-definition diagnostic feed.

“This is a monochorionic, multi-amniotic presentation,” Dr. Salinas explained smoothly, her tone laced with absolute clinical certainty. “Laura is carrying identical triplets. And due to a highly rare, dominant chromosomal mutation visible in the embryonic cell division, these children carry a specific, unique genetic marker—a vascular variance that can only be inherited from a direct paternal bloodline with a history of congenital cardiac framing.”

Diego frowned, his arrogant head-of-the-household facade tightening into a knot of sudden anxiety. “What… what does that mean? What kind of marker?”
