Salem is used to DiMera secrets, but what’s about to unfold in the new Days of Our Lives episode is far more than anything else.

EJ DiMera officially activates his secret lab — a project that even those closest to him don’t know what it’s researching.

And the scariest part? EJ does it all in silence, under the guise of “necessary medical testing.”

Opening Scene: EJ asks Dr. Rolf and Mark to follow him to a locked area of ​​the hospital.

The lab lights turn on, white light illuminating rows of test tubes, data sheets, and biological devices of unknown use. Dr. Rolf — known for being dangerous — smiles suspiciously. EJ whispers, “We’re starting today.” That much is enough for the audience to understand: this is no ordinary test, but something that could threaten Salem itself.

Kayla Brady—the only one sensitive enough to notice the anomaly—accidentally sees EJ coming out of the restricted room. She asks bluntly, “What are you hiding here?” EJ just smiles: “Science… you wouldn’t understand.” Kayla leaves, but her eyes are downcast, clearly suspicious. It’s the moment Kayla looks back over her shoulder—with a chill—that signals she’s going to dig deeper into this secret.

Meanwhile, Mark, who EJ brought into the project, begins to waver. He sees Rolf testing the strange solution on biological tissue, which glows a faint blue. “What are you doing?” Mark asks. Rolf replies, “The next evolution.” The statement sends shivers down the audience’s spine. Because in Rolf’s world, “evolution” has never been a good thing.

What does EJ DiMera want from this experiment? Power? An emotion-controlling drug? Or something even darker—a new kind of “human” bearing the DiMera imprint?

What’s certain is that when EJ plays to the point of opening the secret lab, Salem is about to enter a dark phase. And the only person who can break through that curtain—Kayla—has no idea what she’s about to face.
