WARNING: If you don't want to know what happened in this episode, don't read this photo recap!
Pete fills Kady in on a new terrorist group called The Serpent. They are attacking hedge witches and telling them not to perform magic, going so far as to implant a hideous worm into their body that will kill them if they trigger magic. Alice arrives at the Best Apartment Ever and they fill her in, too. She wants to help. Kady punches her in the face and then accepts her help. It's complicated.

Alice has an idea. Get a map of the entire system of the Library's magic flow and junction boxes. They would need an insider to help them…. And she has someone in mind.
427731
Zelda, Everett and the Library gang are discussing The Serpent. They are tracking the issue and Everett suggests a solution. A temporary "cure" from the Library will stop hedges from using magic if they are infected with the parasite. The Librarians agree.
427704
Zelda, Alice and Alice's mom, Stephanie, are all having visions of Harriet -- trapped in the mirror world. She is split into pieces. Alice offers to help Zelda by rescuing Harriet from the mirror world. And in exchange, she wants Zelda to help them. They all agree. And at the same time, Pete finds out about another hedge safe house attack.
427705
Evil Eliot adds lack of respect for furniture to his list of misdeeds. He visits Penny 23, Julia and Quentin with an update: The dragon's stone is authentic and he only needs one more to achieve anatomical perfection. Then he hits the kitchen for snacks by way of couch trampling.
427706
So the next task for this crew is: Hunt for Enyalius, the god that Eliot says has the final stone. Oh, and try to find out what "The Binder" is/means while they are at it. And EE says he will hurt Eliot's body if they don't do it, and quick.
427707
In Fillory, Margo learns that Eliot is alive. She is so thrilled that she pounces on Josh. The romance is alive! Meanwhile, Fen is definitely NOT telling Margo about the prophecy that she needs to overthrow her. And Josh then tells Margo that he's learned about a man called The Foremost who has special weapons that expel possessions, and he's an expected guest at the banquet he's planned. Well done, Josh!
427708
Alice enlists Fogg's help in her plan to aid Zelda. Fogg has been asked to hand over a list of rejected students to The Library, and he doesn't want to. So Alice convinces him that helping Zelda could be a way to gain leverage and not have to hand over the info in their hunt for hedge witches. Then, in the stacks at Brakebills, Alice hears Julia, Quentin and Penny discuss their search for info on "The Binder."
427709
In the magic lab, Alice starts the spell using the mirrors Harriet appeared in to unite her through spellwork. It seems to be working, as one of the Harriets emerges … and then it isn't. Sparks fly, and then an evil Alice appears. Oops. Good Alice knocks out Evil Alice, and then drags her into a cell in the mirror world. Tough times.
427710
Ru, the Queen of West Loria, arrives for the banquet. And she's been told prophecies, too. She needs to aid Fen in dethroning Margo. But Fen is not on board ... so Ru threatens her. If Fen won't overthrow Margo and have her banished then Ru will overthrow them both. Standing in the shadows, Josh overhears their exchange.
427711
Evil Eliot brings a rando psychic back to the Best Apartment Ever. He wants to do some telepathy in order to search his past and this poor, tied-up guy is the first attempt. He basically immediately dies. Penny offers to go next, and he and Julia have a moment -- she doesn't want him to die. He's flattered and she agrees to a date if he lives. (Awwwww!) Then EE reappears and he and "Percy" face off for some brain games.
427712
With Penny's help, EE remembers an altar and some stones. This is in his past. EE is searching for what happened. He remembers the gods, and Enyulias. Evil Eliot seems to be traumatized and remembers a woman being sacrificed.
427713
Penny spots a door and goes through it. He finds the real Eliot in the Physical Kids club -- a "mind palace" moment -- and the true Eliot has a LOT to share and a tiny amount of time before Evil Eliot is calling for "Percy" again. Penny runs to his side. As they emerge from the memory, Evil Eliot is thrilled at his new realizations and takes off to find someone for Enyalius. And Penny is unconsious on the floor.
427714
Kady and Zelda have a bonding moment as they wait for Alice to finish her spell. Zelda shares that her mother was a hedge witch and she was rescued by Everett. She also explains that she trusts Kady to make the right choice in tough situations.
427715
Harriet forces Alice to realize that in order to complete the spell she has to go back and get Evil Alice. In the mirror realm, Alice confronts herself. They argue, notice and grab a book called "The Binder," and then both Alices go through the lookingglass. They repair the crystal and start the spell again.
427717
Josh fills Margo in on Fen's chatter with Ru. Margo is pretty pissed, and goes to talk to Tick. She gets some intel on The Foremost, and learns that there is no way that he and his axes would attend a banquet in Fillory. The only way for Margo to see him would be if she were banished. Which gives her an idea. So Margo forces Fen to dethrone her.
427718
Margo is branded and banished by Tick. As she is led away she screams that their grandkid's grandkids will fear her name. And also tells them to be nice to Fen, their new Queen. Even though Margo made this happen, it's devastatingly sad. After receiving parting gifts from Josh, and a tender goodbye, Margo is on her way out of the kingdom and in search of The Foremost.
427719
After a long delay, Alice and Harriet emerge from the lab at Brakebills. Zelda and Harriet are joyfully reunited. (Alice appears to be just one Alice. Phew.) Zelda tells Fogg that she will misplace the student list that The Library had asked for. And then Harriet updates Zelda on all of the things she observed from the mirror world. Turns out, Everett has been lying. About lots of things.
427720
Harriet lets Zelda know that The Serpent is not hedges turning on each other. It's actually Everett and some Library cronies that are working to spread fear and track hedges. Pete is captured and given an ear worm -- just one of many trapped and tracked.
427721
Penny wakes up and rushes to Quentin and Julia. He has news from the true Eliot. Turns out, they've been wrong about everything. The stones are not for rebuilding his body, but something even worse. OMG! What??!!
