Saw everything except the Quarantine sign. Someone with Tivo... oh wait, Tivo doesnt get commercials.
Ok, First off I dont trust the Producers, they are very very sneaky. They show Kate in the hatch, and the light comes on and she scream. What that tells is that at some point Kate will scream, at some point she will be in the hatch, and at another point, the light will turn on. Though I bet these things don't all occur at once.
