- Story Arc: Avalon Mystic Tour
- Characters: Goliath, Elisa, Angela, Bronx, Tom (AKA Guardian), Princess Katharine, Gabriel, Ophelia,
- Enemy(ies): Oberon
When Goliath and company return to Avalon, the faerie lord Oberon and his queen Titania return as well after a millennium-long exile. Trouble ensues when Oberon decides to evict the Avalon Clan from his island.
Oberon and Titania return in "The Gathering".
This episode contains the following tropes:
- Cold Iron: Though prior episodes showed this in various way, with the very first time being Demona using iron chains to bound Puck in "The Mirror", it is confirmed in this episode that iron is a weakness to those of the Third Race.
- Continuity Nod: Banshee accused Goliath, Elisa, and Angela of being part of a plot bring the Children of Oberon together for the Gathering. At the conclusion of this episode Oberon initiates his plans for this event.
- Convection, Schmonvection: At one point during Goliath, Angela and Gabriel's battle with Oberon, they all go through and around the lava of a volcano none of them hampered at all by the highly heated air. Though to be fair, gargoyles are made of tougher stuff than humans, and Oberon presumably has magical defenses against extreme heat.
- Nerf: By Third Race standards at least. Before Oberon battles against Goliath, Angela, and Gabriel, Titania puts a handicap on Oberon to at least give the gargoyles a chance of winning. She says she has “weakened” Oberon to the power level of a Child, but even so he still wipes the floor with the three gargoyles.
- Professional Butt-Kisser: The Weird Sisters maintain a respectful tone towards Oberon and Titania, playing to the former's Holier Than Thou, authoritarian Control Freak tendencies, all for the sake of getting revenge against Goliath and co for previously beating them.
- Retcon: At the end of "Avalon, Part Three," after Goliath frees the Weird Sisters, they vanish, and so do the chains that had bound them. In "Ill Met By Moonlight," it is established that the Avalon gargoyles had actually recovered those chains for future use against The Fair Folk.
- Shout-Out: Quite a few are made to the works of Shakespeare. The episode's title itself is a quote from A Midsummer Night's Dream, Act II, Scene i; appropriately enough, the words are spoken by Oberon to Titania (though for once, Greg Weisman was not fond of this Shakespearean touch, since the title was too often misread as "I'll Meet by Moonlight"). Oberon says as he prepares to head off after the gargoyles, "The game is afoot," which comes from Henry V's "Once more unto the breach" speech in Henry V, Act III, Scene i (though this line is more commonly associated today with Sherlock Holmes, who quotes it at the beginning of The Adventure of the Abbey Grange). And to top it off, Goliath comments at the end, "All's well that ends well, then."
- Silver Bullet: Discussed by Elisa, who says that she'd probably need one to hurt Oberon. Princess Katharine says that Oberon's weakness is in fact Cold Iron and silver is for vampires and were-creatures. Word of God confirms that these do actually exist in the Gargoyles universe (and don't count among the Races of Earth since they're the result of magical afflictions).
- Weaksauce Weakness: The Third Race are beings of pure magic, often carrying god tier supernatural might, with Oberon himself the most powerful character we've seen in the series thus far. Their greatest vulnerability? Iron, an everyday, commonly available metal.
