This week was an important one for Thor fans, as writer Jason Aaron finally addressed a mystery that's been dangling since his 2014 mini-series Original Sin. The Unworthy Thor #5 finally revealed what Nick Fury said to Thor that made him no longer worthy to wield Mjolnir. No sooner was that mystery solved than another began, but such is the way of superhero comics. While Aaron left readers waiting and guessing for the better part of three years, this is hardly the first time a Marvel series has played the long game.
