Tiana gives Hook a curious look when they’re introduced, almost as if she recognizes him from an early memory. (“My father had a hook just like that, but he’d be a lot older by now.”) Hook introduced himself as “Captain Hook”, and it’s possible he never used that swashbuckling nickname during his brief time as a family man.
Henry is in danger because he has the heart of the truest believer — except that in Seattle he isn’t a true believer. Could the new curse have been done to protect him? (Does the curse require a lethal sacrifice? If Regina sacrificed her own memories of Henry as part of the new curse, would that be enough to power it?)
Rapunzel is the new Rumpelstiltskin. Perhaps that’s another family connection.
