Continuity mistake: In the scene where Emma is taking pictures of Kathryn's car and Sidney shows up, they open the trunk lid. None of them close it, and the camera is on them the whole time, but when David shows up, the lid is closed. (00:08:00)
Revealing mistake: When the newly hatched dwarves are being cleaned, there is a shot where Sleepy is seen from behind as he's drying himself with a towel after getting out of the bath tub, and you can see that the actor is wearing black shorts underneath. (00:09:45)
Continuity mistake: When Bossy is cutting Dreamy's beard, Dreamy asks "Who was the woman I saw?" and Bossy stops cutting, but a couple of shots later, Dreamy's beard is suddenly much shorter. (00:10:00)
Character mistake: In the evening, Emma states that Kathryn Nolan has been missing for 24 hours, meaning that this episode takes place the day after Kathryn disappeared. When Emma investigates Kathryn's car, David tells Emma that he last spoke to Kathryn "yesterday afternoon" (and stresses that he is telling the truth), and that he hasn't spoken to her since he ended their relationship. However, "What Happened to Frederick" establishes that David broke up with Kathryn the day before she tried to leave town and disappeared, because when Kathryn apologized to Regina, Regina referred to the events surrounding the break-up as "what happened yesterday." Emma checks Kathryn's phone records and finds out that Kathryn talked to David on the phone the day she disappeared, but David could not have referred to that conversation, since "Red-Handed" and "Heart of Darkness" both establish that he doesn't remember the phone call because of a memory blackout. Making matters even more complicated is that when Sidney shows up with the phone records, Emma specifically says to him that David told her that he DIDN'T speak to Kathryn that day, which, in fact, he said he did. (00:12:45 - 00:26:45)
Continuity mistake: After the door to door candle sales fail, when Leroy is about to deliver the bad news to Astrid, the position of Mary Margaret's coat, which she's holding in her arms, changes between shots. (00:21:00)
Factual error: In "What Happened to Frederick", Kathryn learns about David's affair and confronts Mary Margaret at school (after taking her anger out on Regina), where students and teachers are milling about. Later, she apologizes to Regina for "what happened yesterday", whereas Emma, earlier that day, seeks out Henry at school. Kathryn leaves Storybrooke the same day, and mysteriously disappears. According to Kathryn's phone records in this episode, she disappeared on a Sunday. However, the day she left, and the day before, was a school day. In the U.S., school classes are not in session during weekends. (00:38:25)
Continuity mistake: In "The Shepherd", Kathryn is showing David their house, and you can see that the street number on the Nolans' house is 244. In this episode, when Emma is looking at Kathryn's phone records in the evening, the phone records list her address as number 4. (00:38:25)
Continuity mistake: Leroy is walking by and Astrid she accidentally dumps glitter on his head. She wipes his face off; he has glitter on his moustache. It disappears. The camera pans back to him and there is glitter on his moustache again.
Red-Handed - S1-E15
Continuity mistake: When David is interviewed at the sheriff's station, after Emma says "And honestly, liars have better material", her left thumb is resting on the edge of the coffee cup in her hand. In the next shot, it's not. (00:01:20)
Red-Handed - S1-E15
Continuity mistake: In the scene where Ruby reconciles with Granny, in some shots, her necklace is tucked into her clothes. In other shots, it's outside her clothes. (00:36:25)
Continuity mistake: After Charming gives Rumpelstiltskin his cloak, the cloak keeps changing position on Rumpelstiltskin's table. (00:22:05)
Revealing mistake: At the end of the episode, when Emma goes to Gold to ask for his help, we can see he's wearing a wedding ring on his left hand in addition to the usual ring with the light blue stone he wears on the right. That's actually Robert Carlyle's own wedding ring; as he wrote during a twitter Q&A session, he forgot to take it off before they started to film. (00:40:35)
Continuity mistake: When Emma wakes up on Jefferson's couch, her left tank top strap changes position between shots: First, it's at the edge of her shoulder. When she sits up, it's off her shoulder. In the next shot, it's on top of her shoulder, before moving back to the edge of her shoulder in the following shot. A couple of shots later, it's at the top of her shoulder, even though her hands are tied behind her back, and she could not have moved it. (00:10:20)
Continuity mistake: When the Mad Hatter and The Evil Queen are in the portal of doors, on the left side of the mirror, there's a door with green curtains. The design of the curtains changes between wide shots and the shot where they enter Wonderland. Most notably, in the wide shots, the curtains have brown edges, but when they are standing in front of the mirror, the edges are green. (00:15:55)
Continuity mistake: When Jefferson hands Emma the scissors, the sharp end is pointing towards Emma. However in the next shot the sharp end is pointing in the opposite direction. (00:24:35)
Continuity mistake: In the Queen of Heart's maze, when Regina closes the hedge to entrap the pursuers, the spears sticking out from the leaves change position between the wide shot and the close-up. (00:26:10)
Continuity mistake: When Emma and Jefferson are struggling over the gun, the gun keeps changing position on the floor, without anyone touching it. (00:34:00)
Continuity mistake: When Regina first kisses Daniel, her head is tilted to the left. In the next shot, her head is tilted to the right. (00:05:05)
Continuity mistake: When Regina is standing by the tree with Daniel, as she says "Have you not seen her magic?" Rocinante, Regina's beloved horse, is standing next to them. In the following wideshot, Rocinante is nowhere to be seen, and there was not enough time to move away from them. (00:08:05)
Continuity mistake: Regina and Daniel are in the stable. Regina's hands are on his face, he reaches up and pulls them down, cut to behind Daniel and her hands are back up on the side of his head. Cut back to side view, and Daniel's hands are still holding Regina's down. (00:16:40)
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.
