sorry i wrote sloppy i'm just trying to get the gist down.
did you get that last post...? Image Broadcasting at its finest. See, even though kevin wasn't in direct contact with gary, gary's motive was ultimately broadcast to him through the people that were. first the motive was broadcast to gary's tutor who broadcast it to his grilfriend who broadcast it to the therapist, who, unfortuneatly, broadcast it to his unaware patient, who didn't know that every time he went to his therapist's office he subliminally picked it up off of him. this is why kevin kept getting paranoid (the image broadcasting theory) but didn't know why. subconsciously or subliminally he knew, it was a symptom of carrying gary's motive with him. but he couldn't consciously know because he couldn't detect or relate the feelings to anything. low and behold kevin get's so paranoid that he actually buys a gun. he wants to kill this feeling, whatever it is, that wants to kill him (could this possibly be the motive talking to him...? wispering in his ear. but what is it saying...?) at the end scene, in the room there is gary and it just seems that they so happen to be in the same room as eachother when kevin has a gun. gary says, "fagot" and pays the price for doing so. kevin kills the source of the paranoia, the source of the image and that is why he becomes freed. this will surprise you, but gary actually had his motive accomplished through the indirect broadcasting chain that lead to kevin. gary, actually had a death wish because he was struggling with thoughts of inferiority. that's why he was so mean, gary thought bad of himself that's why he was so judgmental of kevin, because kevin resembled what gary hated about himself.
see, the psychology is basically thus, kevin is a mirror image of some part of gary. gary doesn't like this part of himself so he tries to smother that part out that he sees in other people. everytime gary sees kevin he is reminded of that part of himself and starts to actually hate himself to the point where he subconsiously wants to kill himself. but the catch is he can't do it himself. so the motive is broadcast everytime gary feels bad about himself and is in contact with other people.
now, the ending is important because this is the first time gary and kevin are both in direct contact with eachother. so gary really feel s bad about himself and you guessed it, he broadcasts the death motive directly to kevin who fulfills that motive. and consequently goes to jail.
This would be an example of image broadcasting in a movie or script.
pretty awesome huh...?
