The Hamlet Project

If we are to trust the verse, Polonius chimes in with this as soon as the king has welcomed the ambassadors home. Polonius doesn’t give the king time to see the ambassadors out or wait for the king to turn to him and ask for his news. He gives his judgment on what has just come to pass. It could be read as a comment on the good news or as a compliment for the king’s handling of it. If it’s a compliment, it could be seen as slightly condescending to a king – a sort of “Good job, King!”
It is interesting that the king does not speak again for quite a few lines after this. I’m wondering how he takes this bit of commentary from Polonius.
