Yep, I positively hated that "little" aspect about Hook. Posted something about it too (a couple of years back). WTF Disney? We think infidelity is cool now?
Later on, Tinker Bell lays a big smooch on him, goes in for a second one, and it suddenly dawns on him that HE LOVES HIS WIFE.
Yep, cheating if I ever heard it. And then Tinker Bell's "goodbye" to him when he awakens near the statue in front of home. Yeah. Sounds like a "gentle, letting you down nicely" kind of goodbye instead of, say, a good strong NC "I love my wife, you tramp fairy, don't even blow your pixie dust near me ever again!"
I wonder if Moira joined SI after Pete came home and told her all about his journey to self-discovery in Never-Never Land.
