Anybody a fan of fan fiction? That’s when somebody takes the characters from a well-known story and runs off with them in some other direction. It’s particularly huge in the Star Trek universe, although Shakespeare has also gotten the treatment. I personally started one called “Ophelia’s Song”, which had the premise that Ophelia and Hamlet were plotting everything together, until Hamlet went overboard and killed her dad causing her to go nuts. I never finished it.
