History Recap / FateGrandOrderEvent61ChaldeaSummerAdventure

* DenserAndWackier: Par for the course for a Summer Event, but Douman's shenanigans here is nothing compared to the barbarity he pulled off in Story Chapters.

* ThievesCant: "Pirate Penmanship", which is a form of writing used by pirates that is incomprehensible to others save for Blackbeard. Rather than being some coded language it's simply written text as affected by the motions of the seas from the hands of questionably-literate sailors.

* SharkMan: A new mob that is a bipedal shark pirate makes its debut in this event. The party's reaction to it amounts to "You all saw that, right?" with the protagonist in particular being worried that Jeanne is somewhere around here. At the epilogue of the event, the evidence points them of being Pirate C's familiars.

* ThePromise: Played with. The subtitular Boy Pursuing Dreams is Kid Columbus and the Girl Who Dreams is the current Da Vinci. The two had met as children with Columbus promising that he'd sail and find a Dragon, with Da Vinci promising that they'd buy it. The ambiguity comes from the fact that there is no record or proof that real-life Da Vinci and Columbus ever met as kids, that they ever made such a promise, with the two servants even not sure if they ever did such a thing, plus Kid Columbus isn't even certain he's an actual child version of Columbus, and the current Da Vinci isn't exactly the original Da Vinci as well.

* ChronicBackstabbingDisorder: To no one's but the recipient's absolute shock, DOUMAN betrays Chris at the final hour. Just about everyone admits Chris had it coming though considering [[MistreatmentInducedBetrayal all the offscreen abuse he put DOUMAN through]].

* TheDogWasTheMastermind: During the epilogue, Achilles wonders who was it that set up the Seven Treasures and all the traps and challenges in the first place. Based on everything that was prepared, the mastermind would at least have to be a pirate and a mage (and know a bit about Japan), and his mind then briefly wanders to the random NPC that kept appearing named Pirate C. Chiron gives out that another name for mages is Conjurer, but Achilles dismisses the entire thought in the end.

* ADogNamedDog: The group names the stegosaurus they find made from a Holy Grail fragment...Steggy.

* TheFourGods: In the event's second half, Kama sets up four treasures for the protagonist to find guarded by these very beasts...or rather [[ClosestThingWeGot several monsters that vaguely fit their theme]] (and Jaguar Warrior for Byakko/White Tiger) that she powered up to better their positions. For the final "treasure", she faces the protagonist herself rather than use a Yellow Dragon analogue.

* ChronicBackstabbingDisorder: To no one's but the recipient's absolute shock, DOUMAN betrays his master at the final hour.

* WelcomeBackTraitor: Caenis may have been hired by Goredolf to be the Security Officer of the group, but that doesn't stop them from deciding to team up with enemies, and then switching back to Chaldea after losing. The penultimate boss battle is also Okita Alter, but returns to the fold after being defeated.

* ApocalypseProofing: To the incredulity of some of the cast, many of the booby traps and guardian monsters put in place to protect the Holy Grail fragments are still active despite years having gone by since they were first installed.

* PlotTailoredToParty: Each member of the core group gets to contribute at a crucial point in the protagonist's quest to reassemble the Holy Grail. Some like Blackbeard get to be of assistance consistently with how he's the only one who can read "pirate penmanship" while others just happen to be in the right place at the right time.
