Didn't show what happened to the head? (Spoilers)
When he garottes/decapitates the boss lady at the end, it just shows him holding her - still conscious - head and that's it? Doesn't destroy the head or body or anything, just leaves it and walks away? Who says she won't make a recovery like the union rep did. I thought maybe he was going to throw her head in one of the fires or something, but just nothing.
Seems sloppy to make so little of it when she's the 'big bad' in the movie.
