The 100th episode of Lost airs - a Daniel Faraday (Jeremy Davies) special - on April 29th and you can see the preview below. Sawyer will ask Kate to stay. Jack, like the beloved idiot he is, will jump into the fight. Faraday is supposed to come clean about why he's on the island.
On Wednesday, we get a clips special that will "tell the story of the Oceanic 6 in a whole new way." I'm hoping they put it in order so we can see if we've connected the dots properly.
I avoid spoilers so I can't tell you what's coming up. But, if you want to ruin the suspense and the horror and your entire experience watching Lost the past umpteen years, suit yourself. Here's one link and another that may help you out.
