Days of Our Lives (DOOL) spoilers for Thursday, March 12, reveal that Dr. Wilhelm Rolf (Richard Wharton) will discover something that catches him by surprise. Cat Greene (AnnaLynne McCord)

will also do what Kayla Johnson (Mary Beth Evans) asks, so here’s what DOOL viewers can look forward to. Now that Brady Black (Eric Martsolf) has brought up Owen Kent (Wes Ramsey)

as a possible kidnapper suspect, Steve Johnson (Stephen Nichols) is ready to dig for more answers. That may lead to Steve realizing Owen is the night guard in the secret lab

that EJ DiMera (Dan Feuerriegel) has been hiding. Of course, EJ doesn’t know Owen is the one watching over Lexie Carver (Nikki Crawford) since Dr. Rolf is overseeing things.

Owen hid his face from EJ when they crossed paths in the lab, so it’s clear EJ is in the dark.

However, EJ will fall under suspicion since he was tied to Stephanie Kiriakis’ (Abigail Klein) previous abduction drama and the obsessed Owen nightmare she endured.

Kayla doesn’t trust EJ anyway and will trust him even less as more revelations come to light.

Days spoilers say Kayla will ultimately ask Cat for help, so Cat will try to crack the code to the secret lab soon enough.

In the meantime, Owen will fume over Stephanie’s latest trick and phone theft.

It’ll lead to Stephanie getting tied back up, but at least she got a 911 call out that could potentially be traced.

Later, Dr. Rolf is in for a shock when he finds Stephanie and Jeremy Horton (Michael Roark) in that storeroom.

Although Jeremy and Stephanie will plead for help, Dr. Rolf may worry it’s too risky to let them go.

It could lead to the cops investigating down there and pumping the brakes on Dr. Rolf’s groundbreaking research.

Nevertheless, Jeremy and Stephanie join forces on another freedom plot. Days spoilers say Stephanie and Jeremy won’t give up on finding a way out of this mess.

Back with Steve, Days spoilers say he’ll recruit Rafe Hernandez (Galen Gering) to investigate the lab.

It looks like there may also be some surveillance footage that comes into play, so that could provide more evidence.

Alex Kiriakis (Robert Scott Wilson) will team up with Rafe on a lab search before the week’s over, so stay tuned for all the stunning news and dramatic moments to come.

Until then, EJ will divulge the rest of his plans to Paulina Price (Jackée Harry) now that she’s decided she won’t stand in the way of this project and Lexie’s resurrection attempt.

Days of Our Lives spoilers say another action-packed episode is in store, so don’t miss all EJ’s revelations, the hunt for Owen and more.
