The stage direction right before this line is: Enter a Messenger. This is why my theatre company is called Messenger Theatre Company. Because something is ALWAYS about to happen as soon as a Messenger enters. A messenger never enters to deliver no news. A messenger is a catalyst. A messenger moves things forward. “How now!” is an appropriate response to a messenger’s entrance.
I wonder, though, how I might use it as a company slogan. I don’t think it would take.
Enter a Messenger.
