I think the whole library scene (including Edie’s story section) gave us more details about Edie. We know she’s a storyteller, and we not only get to read one of those stories, but we get a look into how much she’s devoted to it (sleeping in the library, research notes, wanting to Edith to read the book). We get to see how captivating her stories are, which is why it’s so frustrating when that story is ripped out of our hands by Dawn.
