Dude - that's no good! We just saw Walt get taken again, Michael swimming after him yelling and sobbing. Sawyer surfaced, found some floating wreck, yelled for Michael and Jin, saw Michael (Sawyer calls him Mike. Whatev.), swam over, pulled him onto the wreck. Michael wasn't breathing, Sawyer started pounding on his chest and was in danger of saying, "Don't you die on me!" but didn't.
Then we flashed over to the light in the hatch going out, Locke screaming after Kate, and starting down the hatch.
I think we heard Jin shouting back there in the water, too.
Signal back yet?
ETA: Never mind!
