can someone help me figure this out?

I'm not sure if it was the looks. Everyone looks like their character in the book and Emma has seen most of them.

Personally, I think that what 'the mad hatter' told her, got planted deep wit in her mind. And her eyes were somewhat opened at the similarities between the book and Storybrooke.

I'm not entirely sure about it, though. Hopefully we will find out thêm in the tiếp theo episode.

No, it was when Emma was in Jefferson's house.
