The Hamlet Project

Ah ha! One letter. The king gets ONE letter. All the talk of LETTERS from the sailor is reduced to A letter to the king. The other is for The Queen, of course.
But…there has been no mention of the queen in previous talk of these letters. I wonder if there’s some sort of plurality in The King.
Is there some sense of “The King” meaning both King and Queen? Like, what Hamlet says when he calls the king his mother, but with royalty.
I don’t THINK this is a thing. But given the tendency of patriarchal culture to obscure, minimize and objectify women, I wouldn’t put it past it. The way mankind means everyone. The way MAN means everyone. I can see it working like that.
