I've always believed that the total end of the series should play out to having Randy as the mastermind behind it all. It would be a major bombshell and it would also be amazing. Don't get me wrong I love Randy and was upset about his death but what if he is still alive and has been the man behind the scenes this entire time. It makes sense because he's always been in love with Sidney and she never would give him a chance. Even having Dewey finally snap and he a killer also would be pretty awesome too.
