[Mrs Ferg]

I loved this episode. So many questions but one major answer - Henry is not what he appears to be. OK here are my thoughts on what happened.

Blast Doors Coming Down
I have 2 theories why the blast doors came down; (1) To keep the people in the hatch in the hatch whilst the drop was taken place; or (2) a ploy by the others to get Henry out of that room and on Locks side.

Theory (1) - this theory assumes that either the higher beings do not relise Desmond is gone or that they do and are dropping food for the losties. My main theory is that it is some kind of human social experiment so therefore I believe that the food was dropped off for Desmond because otherwise it is nonsensical to drop the blast doors to keep people in the hatch as 99% of them are on the beach and thus more likely to see a plane; hot air ballon etc.

Theory (2); This theory centres around the notion that the blast doors came down to get Henry out of the room and further build his rapport with Locke. I think that there are people watching that Hatch and they have noticed the tension between Jack and Locke (as Henry did). Consequently, they have seen a portal to inflitrate the losties; get Henry on Lockes side. I believe that "they" (they being the others helping Henry) were reliant on Jack not coming back to the Hatch and I think it is a risk they were willing to take. Although it took a whole ep I suspect the actual real time of the doors going down to them coming back up again was not that long.

Blast Doors on their way up
Following on from theory (1) - the blast doors went up because the drop had been made. Boring. So I will continue with theory (2) - I think that Henry made the blast doors go up whilst he was "entering the numbers" again to get on the right side of Locke. I think he was communicating with someone via the computer (i think this is possible and I think it said in the video not to as a scare tactic because they did not want people communicating with either other).

Other points to note - It was good to see Locke and Sawyer playing poker together without it ending into a fist fight. Also, in regards to Henry and his fake ID, it seems that although he is intelligent he has completly underestimated Sayid and Anna.

Thats all for now folks.
