WARNING: If you don't want to know what happened in this episode, don't read this photo recap!
So, it turns out that during the 39 different time loops where Julia was at Brakebills, she was super gifted and a favorite of Dean Fogg. But in this time loop, he couldn't care less and lets her out of the magic-blocking room so she can save herself.
Meanwhile, Kady still has to deal with Reynard and Penny wants to help her, but his job with the Order seems to have just started. He and Kady end up back in front of the Librarian, who's got some tasks for him.
Kady decides to ask a Librarian for some information on how to kill Reynard and learns that there's just no way, but that seems suspicious and she doesn't believe it. Meanwhile, Penny's job turns out to be collecting overdue books, so Kady decides to help him out.
Uhm, and Fen is starting to see Fairy warriors all the time. She thinks they're a hallucination, but remember how Margo promised her child to them? Yep. They're probably not hallucinations. Because Margo is seeing them, too.
The search for Julia's shade continues and Todd (ugh, Todd, right?) tells Julia and Quentin that Dean Fogg knows a person who was very interested in shades. During one of the 39 timeloops, apparently ALICE was very into seeking them out.
The first book that Penny has to collect is from the owner of FuzzBeat - a website with cat videos and news. Those articles also turn out to be coded news for magicians. She shares some info with Kady - no matter what, the library has ALL kinds of knowledge. So...that librarian was lying.
In the royal kitchens, Josh finds a note that there's going to be an attempt on Eliot's life during the wedding. He's furious and the gang decide to defeat the Foo Fighters with a tracking spell. The plan is that Josh is going to sneak an Eliot-likability potion into the Foo Fighters' dinner.
So then this: turns out that overdue book was cursed so that the librarian would open what's called the Poison Room, where the library keeps all of the knowledge that's too dangerous to read. In order to avoid that, that librarian chose to KILL himself. So, it's big stuff in there.
This timeloop version of Alice was in rough shape, and the feelings were all OVER the place. She tells Quentin that shades go to the Underworld, but in order to get there, he needs to find "an ancient one."
