"Popular Mechanics"/ metaphor

"But it was getting dark on the inside too."  This was an example of a metaphor.  It is explaining that even though it was dark outside, it was dark inside.  This meant that it was very gloomy, sad, and frightening on the inside.  In "Popular Mechanics," the husband is leaving.  It is a very intense divorce, especially because it involves a baby.  They both want the baby, and they are both fighting to keep him.  The husband becomes forceful and almost violent.  I think at the end when it says, "the issue was decided," this means that the baby had fallen, and he had been seriously hurt or even died.  This story was very intense, but also made me very sad.
