A new Fringe season 5 promo features one of the Observers explaining exactly what happens to natives who disobey! We suggest that you “heed, obey and serve” their command.

In the frightening video, the Observer explains: “Your loyalty is not expected. It is… required. You will comply with all native directions and regulations.”

And for those insurgents who refuse? Upon discovery, they are faced with a “first-level wipe.” This doesn’t bode well, especially considering the previous promo, which showed Walter being tortured by the Observers.

It looks like this is what happened to Walter, which caused the meltdown of his future self’s brain!

We can’t wait to see what happens in the fifth and final season of Fringe. The stakes have been raised really high as the team faces down against the Observers for the battle to save the world as we know it. While we hope that Peter, Olivia, Walter and Etta prevail, we can’t help but fear that not all the characters will make it out alive.

Fringe returns September 28 on Fox, for its final 13-episode season.
