Trivia: When Kate and Sasha are talking and Kate says "Please, you have to have some idea what this means.". At that time you can see an alien looking person moving reflected in the walls. It moves into view, stops for a second and moves out of view again. This is not Kate because she is standing on the other side of the room. There is also a quiet sound effect as it shows itself.
Question: Can anyone please explain to me the end of this movie? Why did 'they' send an agent into the Cube? Was it just to get information from the hacker girl? Or to get her necklace? Why wouldn't they just kidnap her and shoot her with sodium pentathol? And who are the men at the end, and why do they shoot their own agent?
Question: How long had it been since the time Kate stabbed Simon in the eye and the time he captured Sasha? You can tell by his appearance that it's been a nice length of time, but it's never specified. I don't know much about survival, but it's evident that he had been cannibalizing even before that point, so he had probably been eating people in that whole time so it could have been a very long time. I'm inclined to believe that it's been at least a month, given the dramatic change in his appearance. Can anybody give a clearer response? As mine is just a blind guess.
