Revealing mistake: As Moe French steps out of his florist's van, he is greeted by Mr. Gold and his lackey. As. Gold says, "Well, this is just perfect", in the background, you can see the clock tower building, but without the clock tower (the actual clock tower is CGI). (00:03:50)

Other mistake: In the October 2011 flashback, when Mary Margaret gives Henry the storybook for the first time, he opens it to show Pinocchio and Geppetto in an illustration. However, according to 1-20 "The Stranger", Pinocchio's story was not added to the storybook until later after August came to Storybrooke, several months later. This is confirmed in 4-13 "Unforgiven", where Regina and Henry look at the exact same picture, and notice that the paper is different than the rest of the book, because this particular story was added by August.

Cora: Love is weakness. It feels real now, at the start it always does, but it's an illusion. It fades and then you're left with nothing!
Trivia: The tie Henry chooses to go with the suit he'll be wearing to go to work for his grandfather is identical to the one Gold himself wore in Season 1 Episode 8 "Desperate Souls." (00:15:25 - 00:41:10)
Question: If Rumplestiltskin can see the future, why is he always surprised when bad things happen?





Chosen answer: Even if one can see the future, it can be somewhat vague and left open to interpretation.

He can sees the future all jumbled up. It is like a puzzle, it is hard to put together, but even when he does put it together it is not set in stone the future can change.
