Penny thinks he’s discovered a way out of his Library imprisonment when he finds out about a metro of sorts (through the mouth of a pig) that can transport you out of the Underworld. Though Penny isn't sure where it goes, he assumes it has to be better than where he's at and tricks someone into giving up their ride. Soon after, Hades appears and presents Penny with a compelling argument: Go back to the life you had or stay at The Library and create something better. Back in the world of the living, Quentin and Alice bump heads over her secrets and her father’s death. Despite their distrust of one another, they along with Josh agree to go on the next key mission to Fillory together, but not even having Josh in the room can stop them from fighting.

Meanwhile, Margo and Eliot set up a secret meeting with the other two kingdoms' leaders in an attempt to not only stop the warring, but convince them to join the fight against the Fairies. And as Margo and Eliot hatch new plans to stop the magical creatures, Fen and Julia set out on a seemingly possible task to free them. But when the enslaved fairies refuse to run themselves, they ask for the Fairy Queen’s help. Initially distrustful, the Fairy Queen reveals how the magical creatures were almost hunted into extinction by magicians before agreeing to go back to Earth to save her fellow fairies. Their earthly visit forces The Fairy Queen to decide whether to upheave the entire existence by which fairies live or save those in need.
