Not all is as it seems when a Case 53 cape appears in Brockton Bay. When the truth of her origins are revealed, butterflies happen. Loosely based on the CYOA system but not to any significant degree. Don't expect that to be a reliable compass, since I've cherry-picked things and warped the ideas to better fit with the story. Rated M for a REASON... (It's the Worm-verse, after all).
