Channel 4 did like, this preview thing, where they flashed up a buncha random scenes and really tried to build tension.

Whole buncha it was very "WTF?" like...Jin speaking English? I do wanna watch it, just to see what's happened, they left it so up in the air in the last episode.

The hatch, the raft, walt's kidnap, the others and the black smoke, TOO MUCH TO MISS.
