Can you forgive a monster? Chrysalis certainly didn't think so. But some times help can come from strange places, such as old enemies. Twilight helps the Queen get her bearings, and Chrysalis learns a valuable lesson in friendship from the mane six. One things for sure, Ponyville will certainly never be the same.
UPDATE: I have edited the story, so Chrysalis is more in character.
