“Is it?”
Yes, it is 🙂 What you have listed are things that we already have heard and seen. The remaining episodes, as they do for every story line and every character, tell us more and fill in more blanks. This is what A and E do for every character. Hook is not the exception.
“The only thing consistent in his story is that he was out having some sort of adventure.”
An adventure that has yet to be defined, has it not? It will be in the remaining episodes. Starting, I imagine, with The Jolly Roger, but maybe sooner when he and Henry head out into the night, or he meets up with Ariel as seen in the future set pics.
Every character on this show has unknown histories, personal denials, hidden demons plaguing their last year. All are being exposed as we go.
