Any peril Scully might have been in after the events of Season 10 appears to have left her no worse for the wear. She's doing classic X-Files things in the trailer like staring up into lights emanating from the sky and running through graveyards. Classic.
The trailer also teases the return of Smoking Man and Skinner, as well as some focus on Scully and Mulder's son William, who has been missing from the story for awhile. The hunt for William will loom large. "You’ll see more of William than you’ve seen in a long time," Carter said.
Get ready for more easter eggs, cliffhangers, and foreboding talk about the unknown. Heck, you can have some of that right now. "The truth still lies in the X-Files, Mulder," Scully ominously whispers in the trailer's closing moment. That's the good stuff.
