Not having “knowledge of his enemy” is all the more reason to hang on to the bean if he didn’t have to use it.
What I’m saying is, if Hook knew of another way to get to Neverland, besides the bean….why use the bean?
Why not save the bean for future use….an ‘Ace up his sleeve’ so to speak….
He was dealing with the Dark One…..who know’s what would come in handy in the future when he finally did go to exact revenge?
