Deliberate mistake: During the entire movie nothing is mentioned about the rape of Merrin until the very end, even though it is quite obvious for a forensic investigator to determine she was raped, and something like that would be very important to help find a suspect. This is done deliberately to continue the plot as rape would make Iggy less of a suspect (being her boyfriend for years) and someone like Lee more (known by Iggy and others he had feelings for her).
Question: I can't figure out the ending. After Ig kills Lee and turns to stone, it is implied that he and Merrin are reunited in the afterlife, but all we see is the opening scene of the movie. Is that the afterlife? If so, why would they say that they will love each other for the rest of their lives when they are dead?
