Fox's weird sci-fi series Fringe is slated to return tonight with an all-new episode, and cast members spoke with us last week on the show's Vancouver, Canada, set to reveal what questions will be answered—or not!—as the second season winds up in the months ahead.
There are big spoilers ahead! The newest Fringe episode, "Earthling," airs Thursdays at 9 p.m. ET/PT.
