Answer: Director Dominique Othenin-Girard made the puzzling decision to try and humanize Michael in this film by showing he still had some traces of emotion that could be momentarily reached. Thus when Jamie talks to him, he briefly recovers his humanity, takes off his mask and sheds a single tear. Othenin-Girard felt that this made Michael more frightening, because his evil was so great that even if he still had regular emotions that occasionally emerged, the evil inside of him would eventually take over. But it does kind of come out of nowhere and contradict the other films... hence this idea was more-or-less ignored in future sequels.
