Anybody catch Hatter's quip about "off to see the wizard" during the episode?
Plus, characters are being rewritten, with redemption on hand for both Gold and Regina.
Well, we did see in season one elements for both characters that could lead to redemption, so I wouldn't call them being "rewritten".
This is truest for Gold. I expect it's because the woman is always the really villainous villain. But even he seemed to have been plotting Regina's overthrow from the beginning, via the book etc. But now we know that isn't so. (I think, haven't gotten confused on that?) From mastermind to fellow victim of Regina is arguably a character rewrite.
But Emma can tell when people lie and Emma knows Regina doesn't love Henry. Except that now she plainly does. Seems close enough to a character rewrite to me that it's hard to know what else to call it.
