This response could just as easily be uncommitted small talk type question, a way to continue conversation with someone who has been monologue-ing for some time. It would seem to not be that – because in two lines Laertes will identify said Norman. But…in that case – why ask this question? We have two lines of rather unnecessary information. Laertes re-states something Claudius has already said and Claudius affirms it.
Has Laertes tuned out during Claudius’ fawning raptures on this bewitching horseman? Is this his way back in to this conversation?
