The sixth and final season of Lost may center around an entirely new timeline, but it will also return to its past in at least a couple of ways.

First, Elizabeth Mitchell has confirmed that she'll reprise her role as Juliet, despite the fact that her character was inches away from an exploded hydrogen bomb in May's finale and despite the fact that the actress is starring in a new series, V.

"[I'll appear] pretty immediately, and then I'm not sure after that," Mitchell told E! News this week about Juliet's role next year. "I think it will be satisfactory."

Meanwhile, Josh Holloway says his character's state of mind, following the events of the season five finale, will hearken back to the former, bitter Sawyer.

"I think he's pretty destroyed. All of that growth got ripped away. I think he's gonna be a bit salty again, which I'm looking forward to. All I know is that he's destroyed and has given up on life again and on having any positive lessons. So watch out!"

We surely will. Lost returns to the air in January 2010.
