We're still digesting the questions from this week's episode of Lost: Is someone actually coming to the island? Why was Kate assigned number-51 on Jacob's magic dial? Who is the mother of Jack's sideways son?

We tackle a few of these topics on our Round Table discussion and encourage readers to jump in with their feedback.

But there's only so much time to dwell on the past. Lost airs a new episode on March 2 that is sure to raise even more questions and, hopefully, provide a series of answers. It's titled "Sundown" and it focuses on a possibly-infected Sayid.

Get an early look at scenes from the upcoming installment right now:

You can also check out a clip from "Sundown" below. It's a glimpse into Sayid's revised 2004 universe.
