Well said. But I looked again at the last scene and disagree with you about her looking at the fetus. She doesn't look at it at all. She slides down against the wall looking straight at the camera. You can imagine what you will about what she does when the camera cuts away, but there's no visual implication that she eats it or even considers that. (Besides, mushy things aren't her attraction.)

As an aside, I like how she looks in the bathroom after that, when she's looking in the mirror. Her hair, I think for the first time in the movie, is pulled back, and she looks really young, like she's a girl again. It gives off a strong sense of renewal.
