Continuity mistake: When Regina is standing in front of Rumpelstiltskin's mirror at the end of the episode, as he asks, "What are you gonna do now, then?", the cloth that was used to cover the mirror is lying on the floor. When he transforms her back to her normal form, it is gone. (00:38:45)
Revealing mistake: When Hook is down in the pit, trying to escape the undead Maleficent, after he says, "Maleficent. Love you in earth tones", there is a wide shot of Hook and Maleficent where you can see the face of Colin O'Donoghue's stunt double. The stunt double's face can also be seen in the shot where Hook stands up after climbing on top of the rock. (00:22:20)
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.
