Trivia: Behind the opening title, the Caterpillar's Mushroom can be seen in the woods.
Emma: Have you been reading Henry's book?
Jefferson: Henry? You mean the Queen's father?
Emma: Henry, the mayor's adopted kid.
Jefferson: Oh, Henry. Your Henry. And his book of stories, the ones that you choose to ignore. Maybe if you knew what I know, you wouldn't.
Jefferson: I know what you refuse to acknowledge, Emma. You're special. You brought something precious to Storybrooke--magic.
Jefferson: Stories. Stories? What's a story? When you were in high school, did you learn about the Civil War?
Emma: Yeah, of course.
Jefferson: How? Did you read about it, perchance, in a book? How is that any less real than any other book?
Emma: History books are based on history.
Jefferson: And storybooks are based on what, imagination? Where's that come from? It has to come from somewhere. You know what the issue is with this world? Everyone wants a magical solution for their problem, and everyone refuses to believe in magic.
Emma: Here's the thing, Jefferson, this is it. This is the real world.
Jefferson: A real world. How arrogant are you to think yours is the only one? There are infinite more. You have to open your mind. They touch one another, pressing up in a long line of lands, each just as real as the last. Each have their own rules. Some have magic, some don't. And some need magic.
Jefferson: Stay away from the walls.
Evil Queen: I've got a better idea. The walls should stay away from me.
Jefferson: That's my curse.
Emma: To remember.
Jefferson: What good is this house, these things, if I can't share them with her?
Emma: If you really think she's your daughter, why don't you reach out to her, why don't you tell her?
Jefferson: And destroy her reality? I'm trapped by knowledge. How cruel do you think I am. You think I'd inflict that awareness on my daughter? It's hard enough to live in a land where you don't belong. But knowing it, holding conflicting realities in your head... will drive you mad.
Emma: So maybe you're right. Maybe I need to open myself up more. Maybe if I want magic, I have to start believing.
Injoke: The Caterpillar is voiced by Roger Daltrey, lead singer of the rock band The Who. When Jefferson and Regina enter Wonderland, the Caterpillar turns to them and slowly asks, "Who... are... you? One of The Who's most famous songs, which is also used as the theme to the original CSI, is Who Are You?
Despite his name being featured in the promos, Roger Daltrey gives an uncredited performance as The Caterpillar, and only has three words of dialogue.
Joshua Dallas, Eion Bailey, and Raphael Sbarge are credited but don't appear.
