In Scene 2, Macbeth describes his surroundings by saying, "Light thickens, and the crow / Makes wing to th' rooky wood." How can these remarks also be seen as a metaphorical commentary on the events of the play?

Are you asking about the play because you want to know, or is this a homework assignment?

I'd be glad to give you my opinion if it is for personal enrichment, but in accordance to the rules of AMHD, homework questions are banned.

The play fascinates me and I saw this question somewhere and no opinions about it. I'm asking to find out what other's opinions are about this.

Then why does it sound like a homework question?

In plain English -- "The sky’s getting dark, and the crow is returning home to the woods."

This IS a homework question... it was on my final exam a few years back.
