The razor
There had to have been some significance that the mother of patient in bed 13 brought him his razor--a strange gift to bring a dying man. I think she knew he was being denied morphine and she also knew he only had a few weeks to live and its also possible she sent him the letter that told him of his terminal condition. An act of mercy or a series of coincidences?
The mind boggles with the many questions this movie asks and yet offers so few concrete answers.
