When Will Duke Be Cured On 'Haven'? Duke In 'Hotter Water Than Ever'

Duke, Nathan, Dave, Dwight, and Vince all thought they were in the doomed structure for 10 minutes tops, but Dwight's dashcam revealed that they were underground for closer to an hour. What - or who - could have taken that time from them?

"No one was sadder about Jennifer's death than the #haven5 writer's room," McGuinness tweeted on Thursday. "We tried to give her a proper send off -- and we're not done!"
