Jorge's roommate...and the choking scene
I didn't understand a lot of this movie and I'd appreciate guidance. Who was Jorge's roommate? Was it his brother? A friend? A ghost? Toward the end, he seemed to be taunted by the guy. Also, the guy never seemed to get up in the apartment. I wondered whether he was in a wheelchair, but that was never revealed. And I was most curious about why, in one of the early scenes, the guy asked Jorge if he wanted sex. Was he representing Jorge's conscience?
And off that topic, but still regarding my lack of understanding of the film, was Jorge putting the bone in the soup in order for Amy to choke on it? Was he hoping to kill her because he didn't perceive she liked him or did he hope to save her with the Heimlich maneuver and win her love?
