Blade Runner

But.. in class today, they shot down all of my arguments that the main guy is not a replicant

1) He never took the 'vision' test (as Rachael asked him earlier in movie)
2) All human characters are flawed in some way (Gaff - walking stick, JF Sebastian - bad genes, Tyrell - uber thick glasses) and the replicants are 'perfect' in terms of intelligence and appearance. Harrison Ford is "perfect" in appearance
3) Gaff hints that the main guy is a replicant (he doesn't know it) with the origami unicorn and told him to run for his life. When he told him his mission was 'finished'
4) He doesn't show much emotion or rather 'mechanical' => The scene with him and Rachael.
5) There are 6 replicants, Leon, the snake girl, Pris and Roy are definitely the 4 main ones that the main char killed. The 5th is Rachael.. who is the 6th?

x_x" So bloody complicated for a movie.. do you have more arguments to counter all those?
