In tonight’s amazing Once Upon a Time Season 2 finale, Emma and Regina have a little bonding session, the chipped mug finally pays off, and Henry goes on an impromptu vacay. The episode begins with Hook joining Greg and Tamara in the mines, where Greg uses a pickaxe on the diamond he stole from Regina. This triggers the failsafe and starts to turn Storybrooke into a forest. That's not good.
