Eyes

I actually think it was some weird mambo jumbo at the end because all through the film the main character had light blue/grey eyes as a pair then when she shot "Judas" they showed him with one green and one deep blue eye. After they show the main character getting her hair done they focus on her eyes and she had one deep blue eye and one green eye and in the peep hole the person who opens their eye has the pair of light blue/grey eyes. So I'm guessing when she shot him the body transferred or something? Idk. It was just an observation I saw. It confused me though so I don't really know what happened but someone is not who they originally were.
