After the movie, I asked Y whether he thought Nina had died, expecting some kind of answer based on the story, or the cinematic clues, like the bright light at the end. His answer was something like this:
Well, the shard of glass didn’t seem very sharp, so I doubt it got to her abdominal aorta. Plus, there wasn’t enough blood for that. However, she was very skinny, so there wasn’t any fat to block it, so it probably got through to her muscles, and possibly even through them. I’d say she probably punctured her intestines and, yes, probably died.
Touche, Y. Touche. Has anyone else seen it? What did you think?
