Wish Realm Hook told Original Hook that their stories changed when The Evil Queen's curse was never cast. However, it is known from Season 2 that Hook was tasked with killing Cora the moment he found out about the curse, and upon learning he wouldn't know who he was in the new land, decided to pair up with Cora instead. If Wish Realm Hook's story truly strayed when Regina was going to cast her curse, he would've been with Cora, not at the docks with his crew preparing them for it.
