I have been watching this and understand most of it, but I missed the first episode and wonder if someone can tell me how Emma got to be in Storybrooke if only fairy tale characters are there. How did Henry end up there, was something to do with the book?
Henry tracked her down and she had to bring him back. The implication so far has been that Emma is a fairy tale character. How Regina got Henry has not been explained so far, but she did know that Snow's child was out there somewhere.
