it has been confusing... I think at some point, a character named Jax came into the mix, named after the CW live-action portrayal of the character... I never understood why they didn't just use Jason for the TV show, but there you have it.
don't get me started on Johns... that guy ruins more characters than he ever managed to rehabilitate.
I personally thought the Ronnie/Jason dynamic from the New 52 was a good way to keep all "eras" of the character intact, but what do I know?
