The rich symbolism and complex ideas of the film are brought to the forefront through the dialogues between the two protagonists, Ken and Ray. In the story, they represent two clashing ideologies and their interactions bring forth everything the film is about. The actors do a fantastic job at making these characters feel like fully fleshed-out human beings: they are constantly questioning their actions, bickering with one another and changing their minds. Their views differ on everything, from the most worldly matters to their view on life and death, but these do not prevent them from developing a connection so deep that, when their Boss order him to kill the "boy" (as Ray is referred to), Ken simply cannot carry out the task. We understand Ken couldn’t stop himself from caring deeply for Ray, a young man he feels responsible for, someone he developed a fatherly love for. Or maybe, just plain love.
