Dear Mr. Abrams,

A lot a people want to know what thats all about.

When the person in the hatch (might be Desmond might not, could have been another person as well in the hatch). He gets up and in the background it looks like there is a window with sunlight coming in.

all these people are coming up with ideas about why its there. Some say it was just a montage of the life inside the hatch and time cought up why Locke blew the door open. thats the most popular theory i heard.

i was wondering if you could elaberate on this subject. And please don't make it one of those "you just have to wait and see" kind of answers.
