I think this may have been my favourite ever episode, thus far.

One thing though that struck me though,about the theory that the blast doors came down to keep the person in the hatch while the food drop was made - the doors came down a wee bit before the alarm started up for the button. Surely this makes no sense as it trapped Locke in the living area so without going through the vent the numbers wouldn't have been entered. (Unless of course the person is meant to know what the warning of Lockdown means and get themselves to the computer before the doors come down, but surely Desmond would have thought it imperative to tell them this given the fear he had of the button not being pushed)

And also, if the hatch person is so afraid of the sickness/quarantine and the doors coming down were to reiterate this during the food drop (as someone mentioned) then surely there would be an issue with getting the food down to the hatch. I mean there looked quite a lot so it'd take a good few trips I'd have thought.

I know it seems too much of a coincidence for the blast doors not to be connected to the food drop but something doesn't ring quite true. I think for someone, like Desmond, to stay down there pushing a button without question, for that long,
displays a want of curiosity, or a degree of stupidity or fear. Maybe the vaccine from the hatch is in fact a sort of sedative, to make the person more compliant/submissive.
