Thoughts about the ending (spoilers)

One thing that surprised me about the ending was how callous the man seemed when the woman was taken off to be treated for her ectopic pregnancy. If he was free to escape his prison, he was also presumably free to accompany the woman (and their unborn child) to the hospital. Despite the possibility that both would soon die, he was daydreaming about how impressed the villagers would be with his invention when he shares it with them.

Also I wondered about the woman‘s repeated refusals - ignored by the villagers - to be taken from her home for treatment. She didn’t give her reason so we’re left to speculate as why she didn’t want to leave. Was it because she feared the man, her companion and lover, would be gone when she returned?
