An evil faction within the Catholic church seeks to destroy the Library by finding its four cornerstones. Flynn finds out that his first Guardian Nicole Noone is still alive.
Tropes
- Artifact of Doom: The four cornerstones of the Library of Alexandria (i.e. the original Library) were used to hide the Library in a Pocket Dimension, where it continues to reside. The same cornerstones can be used to bring the Library back into the physical world, except the Library has grown so big that attempts to bring it back will cause it to implode. Nicole destroys one of the stones, rendering the rest useless.
- Bait-and-Switch: The episode starts with Flynn being late to a ceremony involving both him and Eve (one where she's wearing a white dress and the Library room is finely decorated). Then there's a two-fold bait and switch. It's not a wedding ceremony, it's a ritual to tether them to the library. Also, this isn't the actual ceremony, it's a rehearsal.
-
The Cast Showoff: Jacob, Cassie, and Ezekiel have to sing in a certain high key in order to shatter the glass casing protecting one of the cornerstones. Ezekiel is reluctant at first, but then reveals to have an excellent singing voice. - First Love: Flynn had a relationship with Nicole, back when she was his Guardian. While he remembers it fondly and still cares for her, he has moved on and fallen in love with Eve. It's clear that Nicole resents Flynn for moving on, though, and asks him if he dates all his Guardians or just the blonde ones. Also doubles as a Call-Back, since it seems like he has dated all his Guardians from the movies.
- Hypocrite: The secret faction of the Church that wants to throw everyone back to the Dark Ages uses guns and cars.
- Good Is Not Nice: Jenkins. When Eve asks if he would lock her up for centuries in order to preserve the timeline, his response is, "absolutely."
- The Lost Lenore: Flynn mourned Nicole after her apparent death, especially since he was the one who rigged the time machine to explode, and she got caught in the blast.
- The Other Darrin: Rachel Nichols takes over the role of Nicole from Sonya Walger, last seen in the first film.
- The Power of Love: Eve appeals to Nicole's love for Flynn and her duty as a fellow Guardian to help them. Nicole ends up sabotaging the priests' ritual. She then reveals that she didn't do it for the Library. She did it for Flynn.
- Really 700 Years Old: Nicole is now immortal and has taken The Slow Path from where the time machine explosion deposited her centuries ago.
- The Reveal: Nicole has been alive and imprisoned under the Library all this time, which means her younger self could have potentially encountered her. Jenkins (and, presumably, Judson and Charlene) knew about it but didn't tell Flynn.
- Science Is Bad: The evil priests firmly believe that, wishing to throw humanity back into the Dark Ages, so that the Church can once again reign supreme. Since the Library represents the total sum of humankind's knowledge, they wish to destroy it.
- Sinister Minister: An evil faction within the Catholic Church seeks to destroy the Library to plunge the world into a new Dark Age, believing it is for the betterment of humanity.
- Stealth Hi/Bye: Nicole takes a leaf from Batman's book, disappearing the moment the Librarians and Eve take their eyes off of her.
- Time Travel: On Flynn and Nicole's last mission together, the time machine they were trying to stop exploded, with Nicole being caught in the blast. With her body nowhere to be found, he assumed her dead. In fact, she was thrown back centuries into the past. After waiting for Flynn to rescue her, she grew bitter and stole an Immortality Inducer artifact, allowing her to take The Slow Path back to the present in order to exact her revenge on Flynn and the Library for abandoning her.
