WARNING: If you don't want to know what happened in this episode, don't read this photo recap!
Returning from their ordeal in the Underworld, Alice, Quentin and Kady return to the cottage and take another look into the book so they can get their Quest back in gear. What they find is a code that's…music. After some discussion about how to play it, they sit down and find themselves in...
Also, in this world, MAGIC IS BACK! There's a weird thing though: everytime one of them expresses a negative emotion of any kind, everyone in the room just stops moving and stares them down. When they refuse to be positive and happy, they're actually attacked until Todd calms the the crowd down. So... it's dangerous to be cranky here.
Meanwhile, back in Fillory, Margo and Eliot have had a trial by wombat (legit, that's a thing…they meant combat, but…Fillory.) They're given a choice to choose their execution, and they're somewhat tricked into choosing the eternal waterfall, where they'll be dashed against rocks until they bleed out.
As Alice and Quentin try to get to the bottom of what's happening, Kady decides she's going to create a distraction from any of the bad vibes that might create. Todd is, as per usual, an ass and tells her to sing it in E, even though it's in A. But Kady persists. And also, by the way, KADY IS GREAT AT MUSICAL NUMBERS!
Meanwhile, Julia sneaks into the McAllister's house to find Sky, the fairy whose leg Irene has CHOPPED OFF. See, that's what that magical cocaine is made of. Turns out, on Earth, the fairies don't think they have magic powers. But Julia convinces Sky to meet her in the Brakebills lab at some point, so they can test that out.
Josh is tied to a chair as Alice and Quentin interrogate him. Kady, by the way, manages a fake marionette magic trick and joins them. Josh is clearly under some kind of spell, and the gang has to convince him that this world is not real.
On the Muntjac, Eliot and Margo get a little excited that Tick will let them go. But actually? Tick is fed up with them too. He's not helping them, AND he's even roped the Muntjac herself into the part where they're going to row the boat to the rocks and then they'll put Eliot and Margo in a lifeboat and toss them over. They're basically hosed.
Eliot, Kady, and Alice learn that Josh came here via the help of a magic key. When THEY recall that they came here via the piano, Kady remembers that Todd told her to sing in E and not A. And so, when they open the piano, bingo - the key. But how to get out of this version of the cottage without upsetting those partygoers?
When Tick comes down to tell the Muntjac to slow down, she doesn't. That panics Tick, who refuses to untie Margo and Eliot but also causes him to abandon ship with his crew (they don't wanna die!) This does, though, make it seem as though it's curtains for Elliot and Margo, the boat is really heading toward those falls.
Julia has gotten Sky to try magic. And it doesn't go well. In fact, it freezes and kills her. All the while, Julia's magic seems to emanate from her eyes and not from her hands. Looks like Julia's magic is leveling up.
So it turns out that this key is about unity. Quentin explains that the quest brought them to a world for the quester that's been left behind (Josh) - and now they're all unified and can hear each other's thoughts. And can do something together. And so, though it's weird, they have to unite. In song.
