If you haven’t caught it in theaters yet, the teaser for Season Four of the greatest show EVAR is online, in all it’s YouTubery goodness.

The first 3/4ths is basically rehashed footage from Season 3, but there are some flashes of new stuff there at the end. So get ready to go frame-by-frame…as much as you can with YouTube, anyway. From what you can see in the little clips, it looks like next season is going to be good bit darker than what we’ve seen so far. The video’s below, and what I can see of it is after the jump.

Jack’s face
An exploding mound of coconuts
The Hydra Station stamp
Hurley swimming
A knife in someone’s back
A skull from some kind of carnivore
Blood falling on someone’s arm
Kate looking up at something falling
More water
A cow
Oooh…Charlie. Flashback, I guess…though he looks way different than anyway we’ve ever seen him.
