Jamie: He'll never die.
Trivia: During one take of a fight scene between Dr. Sam Loomis and Michael Myers, Donald Pleasance accidentally broke Don Shanks' nose.
Question: Why does Jamie calling him uncle stop him? That and why honor her request to see his face?
Answer: The question was more-or-less answered in a previous question, so I'll copy part of my answer here: 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. Basically, Othenin-Girard felt it made Michael scarier by showing his humanity could be momentarily "reached." Of course, it really doesn't make sense and contradicts the other films... but it was just a decision the director made.
Answer: Sorry about that and thank you.
