Polonius is about to read a letter. His “thus” an intro to text. Thus can also lead to text of the body. His head moved thusly. Thus he took the letter from the hands of his lover. Thus did the main character write to his lady love. Thus did he appear to go mad. Thus did he send his former friends to their death via a letter. Thus did he die. Thus did Horatio live to tell his story. Thus did Shakespeare write it all down. Thus did I write a whole lot of shite in response to it.
