When Flynn is kidnapped by a mysterious figure of incredible power, Eve makes an uneasy truce while the Library grows even closer to death.
- Anthropomorphic Personification: Ray is the Library — or, rather, its living component ripped from it when returned from the void.
- Bittersweet Ending: Moriarty gets away with the Staff, but the Library is healed. Finn and Eve's relationship, less so.
- Brown Note: Pan's pipes put all who hear its music instantly to sleep.
- Buffy Speak:
- Cassandra describes the Eye of Zarathustra as "a sort of stone globe-y thing with crystals, or a crystal globe encrusted with stones."
- Flynn says of his relationship with Eve that "this is usually a lot more banter-y than argue-y, this thing that we do. But we're way over here in argue-y."
- Everyone Knows Morse: Double subverted. Eve assumes that Flynn is using Morse (which the team has relied on before) to secretly communicate with them by tapping his communication amulet, but all she gets from it is a string of random numbers. Jacob quickly figures out that it's actually not Morse code at all but a form of Chinese telegraphy which allows for more information to be communicated in fewer taps... and which Jacob is conveniently familiar enough with to translate.
- Explain, Explain... Oh, Crap!: Flynn and Eve catch each other up on how they managed to get to the same place on different missions...and simultaneously conclude that it's a trap.
- Foe Romance Subtext: Moriarty continues to make passes at Eve, allegiances and goals aside.
- Mission Control: Cassandra plays this role in the opening segment
- Overly Long Gag: Flynn and Eve trying to talk to each other while keeping their hands over the other person's ears. It doesn't go too well.
- Voice of the Legion: Ray lapses into this when upset.
