where did the baby come from?
In the second to last scene of the film, we see the wife stab the husband in the belly rather fiercely.
IN the last scene, we see our protagonist and his wife sitting in the garden with a baby carriage.
I suspect he (and not she) is the mother of the baby. He kept saying how he wanted her inside him. All the visions of internal blood, and eventually a fetus seemed ambiguous.
He is always sick...fainting, vomiting, etc, with an unknown but "serious" health issue.
At one point, she even asks him if he is pregnant.
Am I missing something here?
