I think the Henry thing is just another subconscious thing, there's been so much of it. In the pilot, one of the kids in the class gave the teacher (Snow) a pear not an apple, or Leroy/Grumpy in the prison cell whistling "whistle while you work", there's all sorts of little things they've transferred so beautifully. Regina's office this week for instance, woodland wallpaper and a huge statue of a horse (a reference she made in fairytale land). The question is, who really remembers what? Does Regina know who she really is? Or does Mr Gold? Not to mention the million and one LOST references, has anyone else noticed them? I mean given who the writers are I expected something, but it's endless!
The numbers for the show have been really, really good though so I doubt we're going to be disappointed with a Season 1 cancellation which is good news!
