Dark Shadows - Season 12 Episode 1

Julia warns Morgan not to marry Catherine until after Justin dies because the lottery will be held again so she will not have to be part of it. Every generation someone is chosen by lottery to spend a night the locked room, everyone who has ever entered has died or ended up mad like Justin Collins. Bramwell tells Catherine that he still loves her and is sure she loves him. Catherine tells Bramwell that she loves Morgan and plans to marry him. Morgan asks Catherine to marry him immediately, she is hesitant. Morgan sees a woman in white and claims that this is the night (that Justin will die).
