The final post — and the one that ties all the drama together — is the big picture of Salem’s big blowup.

Four main threads are running in parallel:

– EJ opens secret lab

– Rachel – Brady – Sarah’s nerves are at their peak

– Justin warns Jennifer
– Rafe & Cat are stopped in their investigation

And a spoiler from Soap Opera Digest confirms: “The Mystery Experiment” is at the heart of Salem’s chaos this week.

Imagine the scene: Kayla opens the door to the lab and sees what EJ is experimenting with. Rachel screams in the middle of the hospital after seeing Brady and Sarah. Jennifer stands in court, her hands shaking with the news. Rafe and Cat are followed by strangers while running investigative data.

All in the same day.

EJ will appear to be in control, but the audience knows: the more he controls, the more he is threatened with exposure. Rachel could go straight to Justin and report Brady — a blow that would shake up the entire case. Sarah feels pushed into a place where she can’t belong. Cat must choose between her heart and her mission. Jennifer is forced to make a fateful decision: leave Salem, or continue the relentless fight?

In the final moments of the episode, spoilers predict an explosive scene: either an accident in the lab, or a secret that goes live, or a character gets caught.

And Salem — as always — will not be the Salem of old.
