Revealing mistake: After Ariel stabs The Evil Queen in the neck with a fork, Ariel and Snow White jump into the ocean to swim away. In the underwater shot, you can see that the ones swimming through the water are not Ginnifer Goodwin and JoAnna Garcia Swisher, but their stunt doubles. (00:29:20)
Once Upon a Time (2011)
1 revealing mistake in Ariel
Starring: Robert Carlyle, Jennifer Morrison, Ginnifer Goodwin, Jared Gilmore

Snow Falls - S1-E3
Visible crew/equipment: When the horse carriage is ambushed, just as Princess Abigail can be heard screaming "Please, help me", the camera pans downward and a horse wrangler wearing a blue baseball cap can be seen in the lower left hand corner, hiding behind one of the horses. (00:03:20)
Mr. Gold: She now thinks she's a scantily clad barfly named Lacey. She has a false life, like you did under the curse with Kathryn, only hers apparently involves a lot more alcohol.
Trivia: Every episode intro you can see something hidden in the intro like a building or a creature or a person. This is the same as Once Upon a Time in Wonderland (2013).
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.
