Can you tell me if Elizabeth Mitchell will appear on Lost in season six? She was my favorite actress on the show, and I think after last night, I may have died a little on the inside. Thank you! Sources confirm that Elizabeth Mitchell will appear on Lost next year. But does that mean Juliet's alive and a going concern on the show? Well, we're meant to debate all summer who lived and died in the Lost finale, but you will note that she fell hundreds of feet into the waiting arms of a hydrogen bomb. You'll have to do your own calculations about her realistic prospects for survival—there are many variables to include in your equation!—but we've been asked nicely not to show you our answers. Good luck.
