Revealing mistake: As Hook is chasing King Arthur through the woods, there is a shot of Arthur running, where you can see that the one running is not Liam Garrigan, but his stunt double. In the next shot, Hook is hot on Arthur's heels and you can see that it is Colin O'Donughue's stunt double who is chasing him.

Visible crew/equipment: After Emma and Henry meet Archie in the streets of Storybrooke, as Emma opens and closes her car door, a reflection of a white lighting screen and a camera can be seen on the door. (00:17:00)
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: 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: I know Henry found Emma via credit card and a website. How did he know to look for her? Regina is strict and it was a closed adoption.
Answer: He knows who she is because he knows that the fairy tales are true. He was also shown to sneak out to go see Emma or someone else. Sometimes he succeeded, sometimes he didn't. This is how he knew to look for her despite his strict mother.
