On Days of Our Lives, sometimes a small medical discovery is enough to rock Salem — and this week, all eyes are on Kayla Brady, the doctor who always represents conscience and reason.

She accidentally discovers a secret that plunges the entire DiMera family into crisis: Thomas’ DNA does not match Chad’s!

The episode opens on a cold, rainy night at Salem Hospital.

Kayla is on duty late, going through medical records.

A document bearing the name Thomas DiMera is mistakenly delivered to her desk. When Kayla opens it, her eyes freeze — the DNA test results clearly state: “No match.”

A close-up of Kayla’s face, trembling, her breathing labored. She mutters, “It can’t be… Chad isn’t my biological father?”

Just then, Kayla’s best friend Marlena Evans walks in, seeing her panic. The short but tense dialogue left viewers breathless:

Marlena: “What did you just read, Kayla?”
Kayla: “It’s Thomas’s profile… the DNA doesn’t match. If this is true, their family will collapse.”

Marlena advised her to check again, but Kayla – who had witnessed too many tragedies in Salem – understood that whether true or false, if this information leaked, everything would fall apart.

The ending scene of the episode gave viewers goosebumps: Kayla stood alone in the hospital room, looking out at the rain, her hands trembling with the file. Her inner voice rang out:

“What should I do now? Hide the truth… or destroy an entire family?”

This was the moment that started a series of breathtaking dramas, opening up the “DNA nightmare” that shook Salem.
