The Scarlet Letter - Pearl the Fey Child?

The passage on pg. 83 beggining, "...to persue the little elf..." and ending, "...made her mother more doubtful than before." Also the passage on pg. 84 beginning, "Pearl was born outcast of the infantile world. An imp of evil..." and ending, "she had no right among christened infants."
I like these two quotes because Hawthorn is using fey to describe Pearl, but he's using the two different kinds of fey. He sometimes refers to her as an "elf" or "sprite": Sprites are a small species of fey usually talked about when one speaks of playful mischief in the garden. They are fleeting fey, very hard to catch, and not particularly bright. Elves are considered the wiser of the fey species, the larger and not as mischievious, but more melevolant in nature. Pearl seems to be both of these things: her playful spirit and yet not being amenable to rules, her dancing and laughing and yet her "trait of passion" are all those associated with these fey. But then he switches and uses the term "imp". Imps are devil fey not commonly associated with elves and Sprites (I could go into the long difference between the two, but that would digress from the point). The Impish side of Pearl is brought out constantly because she is a product of sin - a "devil child", if you will. I think its really interesting that, even though he uses these two very different species of fey to describe Pearl, he conveys the message to the reader that she is not of this earth. She is, in some ways, unattainable and surreal. Pearl's personality - her "freedom from broken law" which makes her the most like the Fey - is ironic because Dimmesdale, who is also technically "free" because he broke the law, is not free at all due to his ties to the church. He is the only one of the "sin triangle" that is not free, because now Hester is free to disregard her previous way of life if she wishes, although she chooses not to. I think, though, Hester will find it is easier to live as her "elfin child" does rather than living racked with guilt. It's time to move on.
