Im a huge Once Upon A Time fan and even I can barely figure out the puzzle. It would be nice if you could add some descriptions of the characters. Like for Peter Pan you could do something like Who said this quote and you could put a quote Peter Pan said in one of the episodes like "What, a one handed pirate with a drinking problem?" Or something like that. I sincerely hope you take my suggestion.
