- SPOILERS - . . . . . 1) There is no alien robot. It's the guy's imagination. That is for certain. Here are just a few clues: * At the end where the robot vanishes was the first clue for me, which made me go back and watch again. * The picture of the alien at his back, at one close-up scene you'll realize it's from a sci-fi magazine. So he probably saw it and imagined the whole thing. * The fact that we see towards the end, that his "office" is actually an abandoned warehouse. * In the beginning he says "everyone thought it was a comet" Well, it actually WAS a comet. * All the things the psychologist woman saying about out inner thoughts surfacing. * What happened to the 5-6 other aliens which came? Nothing because they didn't exist either. * All throughout the film, you actually see the guy is a little crazy. * They ask the woman "what happened?" And she says "something metaphorical came between us"
2) The woman is actually talking about the man who went crazy. She's not talking about an alien or something.
3) For the military man, I have 2 ideas. He's the guy in the bus which the crazy guy takes everyday to go to the beach. So either the crazy guy saw him and imagined him to be the retired defence secretary, or he actually is a retired defense secretary who thinks this lunatic who "keeps on telling everyone that there's an alien" is a threat. Since he's retired, he doesn't have anything better to do so he follows him everyday to check if he's a potential threat.
There are lots of more details in every scene which I didn't write here, and probably even more which I missed. After all, this is the only short film, along with "Unedited Footage of a Bear" that I gave 10 out of 10. Because this is how a short film is supposed to be. It would be worse if it was a feature length movie.
