The Hamlet Project

Asking someone with questionable moral character
To improvise a character assassination
Is a bit like asking someone who just loves murdering
To just take a chunk out of someone.
I’m making an assumption, of course, about Reynaldo’s character.
I’m assuming that, because Polonius is giving him spy work that he’s not the MOST moral of men.
Anyway, which forgeries would please Reynaldo to put upon Laertes? Has he been looking for an opportunity to impugn him? Is this a moment for a vivid imagination to cut loose and paint a picture of a man debauched and wild ? Polonius figures he’ll let him improvise.
He doesn’t want to put limitations on the lying artist.
