When Hook turns up at the restaurant and sits opposite Emma, he has a glove covering his hook as to not reveal this in the real world. There are various rear camera shots (Emma facing) that then alternate between a covered hook, and the hook being shown without a glove back and forth.
Throughout the second half of Season 3 Henry plays the video game Diablo III (2012), an interesting choice given the strong good vs. evil plot in this game. Emma frequently tells Henry to see if he can't "Beat level 23" however, Diablo III does not have this kind of level system. It's a story and takes place in 4 Acts. You can level your character, but she should then say "go level you character, see if you can get to 24."
Jiminy Cricket is shown chirping to Grumpy instead of speaking as he has been shown to be capable in the past. However, in those scenes he has a subtle translator device which he clearly does not possess here.
Various cut scenes from Diablo III (2012) are shown, but not in the order they appear in the game, and, much too close to each other for Henry to be beating the game for the first time.
Emma and Henry are shown playing Diablo III (2012), and talk about what levels they've beaten. In Diablo III, there are no levels to beat. The player's character gains levels through experience.
Also, later in the show, after being asked by Emma how did he become so wise, Henry replies with "after level 16, when I became a knight". In the game, nothing really happens at level 16, and the player can never be (or become) a knight, since this class doesn't properly exist.

When Hook is trying to convince Emma to drink the potion he messes up and says storybook instead of Storybrooke.
