After Julia returns with a list of items, the two perform the summoning ceremony releasing a demon who can remove the cancer from Penny's stomach. As Kady and Julia work on saving Penny, Alice arrives on her parents doorstep to help save them from the lamprey, much to her mother’s dismay. Eventually, she reveals the lamprey’s intentions but it’s just as Quentin (taken over by the lamprey) appears, turning everyone paranoid in their attempt to protect themselves from the magical creature. Meanwhile in Fillory, Eliot tries to understand the power of the first of the seven key's power, but soon sees his ship boarded by a band of pirates. When Margo learns of the pirate takeover, she cuts a deal with the Fairy Queen to get her to the boat in time to negotiate Eliot's release. What Margo has to negotiate, however, is more significant than she realized. Soon, Margo will have to prove just why they call her Margo The Destoryer.
