The third game in the ''Franchise/ProfessorLayton'' WidgetSeries.

The first trilogy concludes with ''Professor Layton and the Unwound Future'' (''Last Time Travel'' in Japan, ''Lost Future'' in PAL regions). One week ago, a demonstration of a time machine went horribly wrong, causing its inventor and the Prime Minister to disappear without a trace. Now the Professor has received a letter postmarked ten years in the future, as that era's Luke asks him for help to undo the chaos that Future London has fallen into.

Please place examples that apply to the series as a whole on the main ''Franchise/ProfessorLayton'' page.
!!This game provides examples of:
* AbhorrentAdmirer: Belle, for "[[AccidentalMisnaming Fluke]]". [[WhichMe The young one, I mean.]]
* AbnormalAmmo: [[spoiler:The slot machine gun that Professor Layton and Future Luke create uses coins as ammo.]]
* AccidentalMisnaming: Belle keeps calling Luke "Fluke," intended as a term of endearment.
* AllLoveIsUnrequited: [[spoiler: Layton, Don Paolo, and Dimitri are all in love with Claire, but only Layton receives affection in return, finally revealing Don Paolo's motivation for his actions.]]
* AntiquatedLinguistics: It's not a HumongousMecha; it's called a "mobile fortress".
* ArcNumber: 10. 10 years in the future, an explosion 10 years in the past, a puzzle about two scientists with watches five minutes behind or forward (which leads to them being twenty minutes late, if you're looking for an answer), and [[spoiler: 10 minutes to escape the fortress because of a watch that only runs for 10 minutes before unwinding - which in and of itself is a metaphor for Claire's current condition.]]
* AreYouSureYouCanDriveThisThing: [[spoiler: Layton is actually asked this twice, the first time by Bill Hawks while the Laytonmobile is still normal. The second time is by Luke when the Laytonmobile turned into a plane.]]
%% * BadFuture
* BehindTheBlack: Hazel has a habit of cowering behind the opaque part of the DS.
* BeneathTheEarth: [[spoiler:The "future" London.]]
* BitchInSheepsClothing: [[spoiler:Future Luke/Clive is considerably more gentlemanly than Luke, but secretly harbors a desire for wide-scale vengeance.]] On a lesser scale, Becky's politeness towards guests depends on whether her grandmother is listening at the moment.
* BlatantLies: [[spoiler: Most of what Clive says while posing as Future Luke.]]
* ButForMeItWasTuesday: Partial example. Layton distinctly remembers [[spoiler:a small boy who lost both his parents on the day of the time machine's explosion, but doesn't realize Clive was that boy]]. It is a partial example because [[ButForMeItWasTuesday it wasn't just another Tuesday]] for him, as that was the day [[spoiler: he lost Claire.]]
* ButNowIMustGo: [[spoiler:Claire, back to the time of her death]].
* ComputerEqualsTapeDrive: The 2 Computer banks attached to the time machine sport data reels similar to ones found on many older computers (Granted, the game takes place in the 60s).
* CaptainObvious: Layton says, "There's something going very wrong," when the time machine had just exploded.
** Then there's this exchange:
--->'''Luke:''' This ladder should lead us down into the research facility.\\
'''[[spoiler:Don Paolo:]]''' Ah yes, Captain Obvious to the rescue once again.
* ChekhovsGun: [[spoiler:The pocket watch which Layton gives Claire in a flashback comes in handy ten years later, to disable the mobile fortress.]]
* ConspicuousCG: [[spoiler: Clive's mobile fortress]] in some of the cutscenes.
* ContinuityNod: Quite a few of them, mostly to ''Curious Village'':
** Luke notes that Don Paolo had once tried to [[FerrisWheelOfDoom run them over with a Ferris wheel]].
** When you tap the Towering Pagoda which is in the distance in the area just before its entrance, Flora will say "That tower is even taller than the one in St. Mystere!"
** When you have to [[spoiler:escape the Pagoda]], tapping the curtain will cause Flora to say, "Why don't we just make a glider and fly away?"
** In the sticker book metapuzzle, several stickers are of ''Curious Village'' characters.
** Luke still has Don Paolo's mask of Chelmey. [[spoiler:It can be seen hanging over the lid of his suitcase when he's packing up during the credits.]]
** There's one to ''Diabolical Box'' as well: Examining the underground railway entrance in Chinatown (without tapping the Shoe icon first) will have Luke say "The railway is useful, but it's no Molentary Express..."
** And one to both games simultaneously: if you tap the manhole cover outside one of the subway stations, Luke remarks, "Remember the last time we went into the sewer?"
** One of the pictures during the credits is of [[spoiler: Layton and Paul frantically running away from the mobile fortress controlled by Clive to destroy London]] ...in the exact positioning as the picture in [[VideoGame/ProfessorLaytonAndTheCuriousVillage Curious Village's]] credits of [[spoiler: Layton and Luke running away from the Ferris wheel sent by ''Paul'' to destroy them.]]
** Another of the credit pictures features [[spoiler: Luke packing the Chelmey mask Don Paulo used in Curious Village.]]
* ConvenientlyEmptyBuildings: [[spoiler:Even with Clive's destructive rampage through London with a giant mobile fortress, there's no reference of any deaths whatsoever, although the game goes about subverting this subtly. The cutscenes actively show the lights in the windows of the buildings that are getting crushed, as if to directly imply that there are people in them. This can lead to Clive becoming a UnintentionallyUnSympathatic character, when you realize how many innocent people he must have killed.]]
* CoolCar: The Laytonmobile goes UpToEleven in this game.
* CorruptPolitician: [[spoiler: Prime Minister Bill Hawks, full bore.]]
* CuteAndPsycho: Puzzlette might count, as she has a punching bag and a ''spiked'' flyswatter, which is a bit overkill for dealing with insects (though her only sapient victim survived).
* DarkerAndEdgier: Considerably so in comparison to the rest of the games in the series. For one, it's the first game in the series where [[spoiler:people actually ''die permanently''.]] The villains meanwhile [[WoobieDestroyerOfWorlds have traumatic backstories]] and not even Layton and Luke escape becoming TheWoobie.
* DeadpanSnarker:
** Future Luke, as seen in this conversation:
-->'''[[SuspiciouslySimilarSubstitute Shmarton]]''': You're one of the fellows behind the incident at the casino, aren't you?\\
'''Future Luke''': Let's say I am. What would you do about it?\\
'''Shmarton''': I'd get my boss Shmelmey to give you a knuckle sandwich...if only he hadn't gone off to the bathroom!\\
'''Future Luke''': Well, lucky for us, he's not here. We'll just be going now.\\
'''Shmarton''': If you run off, I'll make sure my boss squishes you like a bug when he finds you!\\
'''Future Luke''': Duly noted.
** Even Flora gets a bit of this, when they're making their way through the tower in Chinatown.
--->'''Flora:''' Nothing livens up a den of iniquity like a potted plant.
* DemotedToExtra: Subverted. Flora isn't mentioned at all in the first third or so of the storyline, and when you finally do encounter her, Layton seemingly sidelines her. However, when you [[spoiler:return to Future London]] she irately shows up and makes it clear that she isn't going to take no for an answer, and accompanies the Professor for the rest of the game.
* DiscOneFinalDungeon: The Towering Pagoda is built up as the other Layton's hideout for much of the game, but there are quite a few loose ends left over when you're done.
* DoingInTheWizard: Toyed with, [[spoiler: as the "time machine" used to travel between Present London and Future London turns out to be simply an elevator. But then you get to the very end, and discover that the original time machine built 10 years ago ''did'' work, temporarily launching Claire into the present time.]]
%% * DontYouDarePityMe: Subject 3.
* DownerEnding: The ending for the ''game's'' storyline is quite a downer, with the Professor [[spoiler: finding out that he's been with Claire all along, only to have her pulled away from him as he begs her and sobs for her to stay.]] Not to mention, [[spoiler: [[CorruptPolitician Bill Hawks]] pretty much gets away [[KarmaHoudini scot-free]].]] The one for the ''first trilogy'' is more bittersweet, with [[spoiler: Luke gone overseas, but with the promise of more adventure in the future. [[SequelHook Blatantly.]]]]
* DroppedABridgeOnHim: Poor, poor Beasly. [[spoiler:[[SubvertedTrope Or not]]. One of the credit images shows him flying away from Puzzlette's swatter, [[AmusingInjuries injured in a comical way.]]]]
* EasilyConqueredWorld:
** A lone twenty-or-so-year-old with no special connections or background ([[spoiler:Clive]]) is able to single-handedly manipulate the nation's top scientists into doing his bidding and kidnap the Prime Minister with just his money.
** Considering what he's done, the fact that Bill Hawks even became Prime Minister in the first place.
* EnemyMine: [[spoiler:Don Paolo joins forces with Layton because he wants to get to the bottom of what's going on... and for other, personal reasons.]]
* TheFamilyForTheWholeFamily: They're even ''called'' "The Family."
* FauxtasticVoyage: [[spoiler:The game uses one with FakedRipVanWinkle elements in the form of faux time-travel as the antagonist's BatmanGambit]].
%% * FeetFirstIntroduction: Future Luke
* FlashbackToCatchphrase
** We see in this game where Layton got his top hat.
** We also learn why he decided to become gentlemanly, and who inspired his catchphrase "That's what a gentleman does!"
* FlyingCar: [[spoiler:Don Paolo transforms the Laytonmobile into an ornithopter.]]
* {{Foreshadowing}}:
** Hey look, it's [[NoSenseOfDirection Pavel!]] Oh, you're looking for giant underground caverns that some scientists believe can be found all across the globe? Well, good luck with that, thanks for the puzzle, and tell [[Manga/RanmaOneHalf Ryoga]] I said "hi." Come TheReveal...
** Also, another puzzle giver talks about how he [[spoiler:went digging deep into the earth, and wound up in "future London"]]. Luke assumes he just wandered into a wormhole, but the reveal makes everything make more sense.
** Not to mention the statue of the boy and the author. *sniff*
** Two steps outside the clock shop and you can see that it [[spoiler: extends into the sky]].
** A more minor example, but before the first Puzzle Battle, Future Luke poses that the Professor Layton in front of him could be Don Paolo in disguise. [[spoiler: Skip ahead a few hours to the Towering Pagoda, where this is precisely what happens.]]
* ForgotAboutHisPowers: It takes Layton [[spoiler: ''falling off a cliff and almost crashing'']] to remind him that his car can fly...[[FridgeLogic so why didn't he use that feature to get up there in the first place?]]
* FrictionlessIce: A recurring puzzle in this game. It differs from the FrictionlessIce puzzle in that it is often possible (and necessary) to avoid slipping by finding a route around the peels.
* FutureMeScaresMe: And how! [[spoiler:Played straight with Future Layton, and later Future Luke.]]
* GetAHoldOfYourselfMan: It's implied in a flashback that [[spoiler:Layton hit Clive whilst restraining him, to stop him from going back for his parents, after the explosion that killed both Claire and Clive's parents]].
* GogglesDoSomethingUnusual: At one point in the Towering Pagoda, Layton is forced to put on a strange pair of goggles in order to see [[OnlySmartPeopleMayPass the puzzle that will unlock the next door.]] [[spoiler: Their real purpose is to scan his memories of a specific day so Dr. Allen can program that data into his time machine...except 'Layton' was really Don Paolo in disguise, so Allen couldn't have gotten the information off him in the first place.]]
* GreaterScopeVillain: [[spoiler: Prime Minister Bill Hawkes]] is the one responsible for the time machine demonstration that [[spoiler: killed Clive's parents and Claire]] setting off the chain of events leading to this game.
%% * GotMeDoingIt: DING!
* HairRaisingHare: Subject 3. Years of being experimented on have left him misanthropic and cranky enough to give even [[Franchise/SonicTheHedgehog Shadow the Hedgehog]] a run for his money.
-->"Take one more step, and I'll rearrange your kneecaps!"
* HardOnSoftScience: The Prime Minister is talked into participating in the time machine demonstration after Dr. Stahngun needles him over abandoning the hard sciences.
* HeIsAllGrownUp: We get a glimpse of what Luke would look like when he's older. [[spoiler: Later in the game we find out that he is not Luke but a boy named Clive who looks incredibly similar to Luke, which does not really make sense because Luke and Clive are not related.]]
* HeelFaceTurn: [[spoiler:Don Paolo, although he claims [[IWasJustPassingThrough it's only temporary]].]]
%% Hey It's That Voice goes ONLY on the Trivia subpage.
* HopelessSuitor: Poor Rosetta (for Layton) and Belle (for Luke).
* HumongousMecha: [[spoiler:The mobile fortress.]]
* HypocriticalHumor: Layton disappears for a short period when the gang are heading for the Towering Pagoda, and Luke and Flora are naturally concerned. Flora remarks that Luke is "just lost without him," which is a nice bit of pot-kettle-black coming from Little Miss Separation Anxiety. Of course Luke calls her on it, but it's all quite good-natured.
* IceQueen: Bill Hawks' wife, who behaves as though attending the scientific event at the start of the game is somehow beneath her and the food isn't good enough.
* IHaveYourWife: [[spoiler: Clive abducts Flora]] to ensure that Layton will chase him, although the specific motive for this act is never actually stated. [[spoiler:He finally admits that he doesn't really know why, and [[ICannotSelfTerminate guesses that something inside him made him want to be stopped]].]]
* LaymansTerms: Name-dropped by Layton when he's explaining the "memory scanner."
* IncrediblyLamePun: "Paint me <adjective>" from Slate and "drone" from Beasly.
* InelegantBlubbering: [[spoiler: On ''two'' occasions, from both Layton and Luke. Granted, [[TearJerker they were at some of their lives' saddest moments.]]]]
* InterfaceSpoiler: Inverted: the game's interface helps to hide the biggest plot twists from the player by [[spoiler:putting "solved" stamps on some of the mysteries even when the "solutions" found were in fact lies created by the villains. Once the truth is discovered, the "solved" stamp is replaced with a "The Whole Story" stamp.]]
* IntergenerationalFriendship: At one point, Layton and Luke find a statue of an author who became friends with [[IllGirl an ill boy]], and who wrote children's adventure books. Eventually [[TearJerker the boy died of his illness]]. The "author" looks a great deal like Layton [[spoiler:and given that Layton saved Clive, it may actually ''be'' Layton]]. Luke returns to that statue when he's troubled by [[spoiler:the news of his father moving]].
* ImperialStormtrooperMarksmanshipAcademy: In the casino, Layton, Luke and Future Luke are being shot at by [[MoreDakka SMG-toting]] members of The Family, yet no one gets shot despite the large amount of collateral damage. {{Justified|Trope}} in that [[spoiler:the whole city is a {{Masquerade}}, The Family are its [[TheMenInBlack enforcers]], and that Future Luke is not only [[TheMole a mole]], but also their [[BigBad boss]]. He probably arranged the attack to throw any suspicion off of himself.]] Look closely. The Goons aren't even ''aiming'' at anything!
* InstantAwesomeJustAddMecha: [[spoiler: Clive plots to use his fortune to build a giant mecha to destroy London, despite all the more efficient (but less entertaining) ways of levelling a city. ]]
* IWasQuiteALooker: Florence in Puzzle #46.
* JerkWithAHeartOfGold: [[spoiler:Don Paolo, again. He claims that the only reason he modified the Laytonmobile was so Layton could save Flora.]]
* KarmaHoudini:
** [[spoiler:Bill freaking Hawks]]. Despite being the one responsible for the explosion ten years before the present and causing the deaths of probably dozens of people, including [[spoiler:Clive's parents and his lab assistant Claire]], he is never punished. [[spoiler:In fact, he's actually ''rewarded'' for his actions, earning a fortune which he then uses to gain political favor and become the Prime Minister of the United Kingdom. Even by the end of the game, we never see him get comeuppance; all that happens is that Chelmey makes a pointed comment about being blinded by ambition but it goes over Hawks' head.]]
** [[spoiler:It is heavily implied that Chelmey arrests Bill, judging by his comment "I still have ''work'' to do".]]
* LargeHam: Prime Minister Bill Hawks, but only when he's publicly speaking. The contrast between his normal and orating voices is stark indeed.
* LightAndMirrorsPuzzle: One is midway through the Towering Pagoda.
* LighthousePoint: The lighthouse in the middle of the Thames, instead of at the mouth of the river like a normal lighthouse. [[spoiler: Actually the top of the moving fortress.]]
* LeaningOnTheFourthWall: Very subtle, but when you first meet Hazel he is terrified of Layton's hat, so he shies away and hides behind a wall. Naturally, this wall is the side of your DS.
* LoopholeAbuse: Layton and Future Luke try to prove themselves to one another by, obviously, presenting puzzles. Luke starts by challenging Layton to find a spade in a set of four cards, and Layton does the same on his turn. [[spoiler:But Layton's cards don't include a spade - he noticed that Luke never specified that all four cards were of different suits, and took advantage of that loophole to make his own puzzle UnwinnableByDesign. It turns out to have been a SecretTestOfCharacter; Luke was seeing if Layton would catch such a loophole.]]
* TheManBehindTheMan: [[spoiler:Future Layton turns out to be Dimitri Allen aka Dr. Stahngun, who, in the end, was being manipulated by Clive aka Future Luke.]]
* ManlyTears:
** [[spoiler:Layton after losing Claire for the second time.]]
** They start up again in the very last cutscene, when [[spoiler:Luke loses his composure and runs to hug the professor goodbye, before the latter is left watching the boat Luke is on sail away]].
* {{Masquerade}}: [[spoiler:Future London is a fake created by Dr. Stahngun; he kidnapped scientists and made them believe they were 10 years into the future, then enlisted their help in finishing his time machine by telling them it was the only way to get back to their correct time.]]
* MementoMacGuffin:
** As we learn in this game, Layton's hat is one.
** A more plot-critical one is the watch that he gave Claire.
* MiniatureSeniorCitizens: Margaret is about as short as her granddaughter Becky, who doesn't look much older than young Luke.
* MinionWithAnFInEvil: For someone nicknamed "Lockjaw", [[YouJustToldMe he sure can't seem to keep his mouth shut]]...
* MoodWhiplash: Considering all the concentrated awesomeness that had occurred just before, few saw that ending coming.
* MyFutureSelfAndMe: Luke and future Luke.
* NoHuggingNoKissing: Averted for the first time in the series. In a flashback, we see [[spoiler:Claire kiss Layton, and then she does it again at the very end before leaving him for good]]. In the present day, Layton hugs both children at different points. [[spoiler:Flora throws herself into his arms when he rescues her from her abduction, and Luke does essentially the same thing before boarding the steamship for his move to America.]]
* NotSoStoic:
** [[spoiler:[[TearJerker Layton's breakdown at the end of the game, after Claire leaves.]]]]
** And then again at the credits; despite [[spoiler:telling Luke that a gentleman never makes a scene in public, Layton tears up as his sobbing apprentice hugs him goodbye]].
* OminousMusicBoxTune: "Suspicion", which plays over the PreviouslyOn segments, among others.
* PapaWolf: We finally see Layton become truly pissed off when [[spoiler:Clive kidnaps Flora]].
* PollyWantsAMicrophone: The hint coin-finding pet in this game is a parrot. Sadly, the meta-puzzle where the parrot learns words and repeats them back was replaced in the English version.
* PunnyName:
** Rosetta Stone, the archaeology student.
** Also, Puzzlette, for well... obvious reasons. Her name in the Japanese version is Nazolene, "nazo" being a Japanese word for "puzzle".
* RampJump: Taken to a ludicrous extreme at the end of the game and [[{{Ramprovisation}} this ramp is a levee by a river.]]
* RationalizingTheOverkill: [[spoiler:Future Luke, a.k.a Clive created a gigantic underground futuristic version of London, built a giant robot, put up a great farce, and tried to blow up the real London only because his parents died in an unfortunate accident. He then justifies it by saying that it's teaching the government not to callously disregard ordinary people (since Bill Hawks managed to not only avoid responsibility for his failed time travel, but reached high office).]]
* RealityEnsues: First time we get to see Layton at the university he works at and pester a student to finish her homework.
* RedHerring:
** Partway through TheSummation, it really seems like [[spoiler: Bill Hawks]] is going to be revealed as either the BigBad or ManBehindTheMan. [[spoiler: And then Layton accuses Future Luke.]]
* ReverseThePolarity: [[spoiler:The war machine Clive uses is destroyed by switching some gears around to make one of them run backwards.]]
** Although this is a much more realistic example of this trope, as [[spoiler: swapping gears around inside highly complex machinery is sure to do SOME damage, at least.]]
* RoaringRampageOfRescue: What the good Professor embarks upon, like any good PapaWolf, when [[spoiler:Flora is kidnapped]].
* RuleOfCool: After being cornered behind some slot machines by The Family, Professor Layton and Future Luke work together to find a way to escape. Their solution? [[spoiler:To create ''a friggin' machine gun out of slot machine parts'' that had been shot loose just moments before.]] Did I mention that they managed to do this while under fire?
* SaveTheVillain: [[spoiler:Celeste/Claire saving Clive, feeling responsible for what happened to him. Also, in a sense, Layton and company saving Bill Hawks]]
* SequelHook: At the very end of the game, [[spoiler:Luke writes to Layton about a mysterious happening at his new home, which sounds like just the sort of mystery for Layton to solve]]. The game ends, not with "The End", but with "To Be Continued". Now that the prequel trilogy has been completed, perhaps the series will return to this hook.
* ShootTheShaggyDog: All that stuff with the BadFuture and Evil Layton and such? [[spoiler: Meaningless. It turns out Future London was fake and just a setup for some guy (actually Future Luke!) to build a killer robot, so everything you did in the first part of the game was basically for nothing. And then the guy uses the killer robot to blow up a city, he goes to jail; Bill and Dimitri, the ones you discover are responsible for the whole mess, escape unharmed; young Luke moves away;]] and at the very last minute you are told that [[spoiler:Celeste was Claire the whole time, making the explanation for how time travel was impossible pointless, and then she dies with Professor Layton weeping in despair.]] THE END.
* ShoutOut: In a conversation with another patron in the bookshop near Chinatown, Luke remarks that "I've read the SherlockHolmes books at least a dozen times!"
* SimilarSquad: There's a Family member named Layman, who is similarly dressed to Layton and [[BeamMeUpScotty gets several of his catchphrases wrong]]. Layton never comments on this. There are also Shmelmey and Shmarton (Barley and Chelton in the UK version), who are similar to Chelmey and Barton.
* SnowMeansLove: The ending: it starts snowing at the end of the game, even though the weather conditions and the foliage on the leaves would imply summertime. [[spoiler:All while the woman Layton loves walks away into the past and [[SnowMeansDeath towards her death]].]]
* SpottingTheThread:
** [[spoiler: Why didn't the future Dr. Schrader react when the Luke who came to visit him was still an AdorablyPrecociousChild instead of a young adult?]] Answer: [[spoiler: that wasn't Dr. Schrader, and he wasn't from the future.]] And so the web begins to unravel.
** [[spoiler:Dean Delmona's hair is graying, but Layton knows he's bald and wears a toupee]].
* SoftGlass: Averted. [[spoiler:Clive locks Flora in a glass cell, which neither she nor Layton seem able to break. Good thing it had a puzzle lock...]]
* StandardFemaleGrabArea: When [[spoiler:Flora]] is kidnapped, one hand on her upper arm and she is completely helpless. Of course, she's no ActionGirl in the first place. This may be her first personal experience with rough treatment, making this a JustifiedTrope.
* StartOfDarkness: Don Paolo's motivation against Layton ([[RhymesOnADime oh, hey!]]) is finally explained.
* StealthInsult: From Layton to Luke.
-->'''Professor Layton:''' And even in the future, you seem to need my help in solving [mysteries]. Your constancy can be quite a comfort in these uncertain times, my boy.\\
'''Luke:''' Er... Well, thank you... I think.
* StrongFamilyResemblance: Claire and Celeste could practically be ''twins''. [[spoiler:Subverted when it turns out Celeste ''is'' Claire.]]
* TakeYourTime:
** Contains a particularly JustForFun/{{egregious}} example near the end of the game. The BigBad has activated his [[spoiler: gigantic, mobile fortress and is about to begin tearing London apart]], and you want to go back and solve any puzzles you may have missed? No problem!
** Even worse, at the very end, you [[spoiler:install a watch with a stated time limit of ten minutes to stall a SelfDestructMechanism]], yet you can STILL go back to leisurely mess around! Weirdest of all, there's a (telegraphed) PointOfNoReturn right near that point, just like you'd expect -- but it's the puzzle immediately ''after'' the one where the time limit kicks in, so [[spoiler:your final save is guaranteed to one where London is supposedly about to explode in ten minutes.]]
* TeacherStudentRomance: A one-sided version: Rosetta, one of Layton's students, makes thinly-veiled references to how she's looking forward to their private sessions. Layton, for his part, seems to know what she's implying (he stutters a bit) but is clearly not interested. Leads to a humorous moment during the credits, which show Rosetta and Layton in their "private" session... with Luke and Flora. Layton and the kids are evidently having a great time; Rosetta, not so much.
* ThisCannotBe: [[spoiler:Clive, after his machine has been disabled.]]
%% * TimeTravel
* TitleDrop:
-->[[spoiler:'''Claire''': We had so many plans for the future. Do you remember, Hershel? I'll miss you...and our unwound future.]]
** Naturally, the dialogue in the Japanese version also had a Title Drop, but for its own title ("The Last Time Travel"), therefore being a bit different.
-->[[spoiler:'''Claire''': It looks like my time is up, at last. It was nice to see you again. It ended so suddenly. My... last time travel.]]
** It's also slightly different in the UK version, as there was ''also'' a Title Drop for its own title ("Lost Future").
-->[[spoiler:'''Claire''': You won't forget, will you? Our shared past, and our... lost future.]]
* TranquilFury: Layton at the end, once he's worked out what's ''really'' going on here. He remains gentlemanly and reserved throughout, but loses the softer tone in his voice and his beady little eyes suddenly become... unsettling.
-->'''Layton''': This is... ''utter madness''.
* TraumaticHaircut: Well, sort of. [[spoiler:As he watches Hershel and Claire getting all lovey-dovey from behind a tree, Paul's bald-but-long-on-the-sides hair stands straight up in shock, then gradually flattens out and hardens into Don Paolo's trademark horns.]]
* TriangRelations:
** [[spoiler:A variant of type 4, with both Dimitri Allen and Don Paolo filling in the role of A, Claire being B, and Layton as C.]]
** [[spoiler:To be more specific, Claire and Layton were in a loving relationship, while Don Paolo and Dimitri both were one-sidedly in love with Claire.]]
* {{Tropemobile}}: The Professor's beloved Laytonmobile makes a heroic return in this game, with some unexpectedly badass upgrades.
* TwentyMinutesIntoTheFuture: Or ten years. We still don't know ''when'' that means. See the SchizoTech entry on the main ''Franchise/ProfessorLayton'' page.
* UndergroundCity: [[spoiler:While we don't get to see it, underneath Future London is a facility building a [[HumongousMecha huge, city-destroying mecha]]. Considering that "Future London" is a fake built under the real London, we have a HumongousMecha built in an ElaborateUndergroundBase under a BeneathTheEarth city under a major metropolis.]]
* UnfinishedUntestedUsedAnyway: [[spoiler:Dmitri opposed pushing forward the time travel experiment, as Hawks planned to do for his sponsors]].
* UnnecessaryCombatRoll: A few are pulled in the "casino shooting" scene
* UniversalDriversLicense: [[spoiler: Professor Layton is able to fly a plane - rather, the Laytonmobile transformed into a plane (or more specifically, an ornithopter). Strangely, he seems to have a much easier time flying it as a plane than driving it on the ground.]]
-->[[spoiler:'''Luke''': [[AreYouSureYouCanDriveThisThing Uh, Professor, when did you learn how to fly a plane?]]]]\\
[[spoiler:'''Professor Layton''': A plane? [[HandWave This is an ]] ''[[HandWave automobile]]''!]]
* UnwittingPawn:
** [[spoiler:Dmitri plays into Clive's plans without realizing that he's also one of the targets of Clive's revenge plot.]].
** [[spoiler:Cogg and Spring apparently helped Clive with his plan by making the "time machine" elevator, as they were servants of his adoptive family. They, however, had no idea what he was really planning.]]
* TheUnReveal: Just as Beasley's about to tell us all about how he became a Puzzle Bee, [[CuteAndPsycho Puzzlette cheerfully interrupts him with a flyswatter. Several times.]]
* VerbalTic: A prominent NPC has one. Is it Cogg? '''BZZT!''' Beasley? '''BZZT!''' Max? '''DING DING DING!'''
* VillainousBreakdown: [[spoiler: Clive, once Layton uses ReversePolarity on his WeaponOfMassDestruction]].
-->[[spoiler: '''Clive''': ''This isn't happening.'' It can't end this way. IT WON'T END THIS WAY!]]
%% * VoodooShark
* WhamLine:
--> [[spoiler:"You've taken awfully good care of that hat I gave you."]]
* WhichMe?: Luke. Layton solves this by referring to them as "Big Luke" and "Little Luke".
* WoobieDestroyerOfWorlds: [[spoiler:Clive, who has a grudge against scientists and politicians because he lost his parents in an accident caused by Dimitri and Bill Hawks' time machine experiment exploding; and is willing to destroy London to teach them a lesson.]]
%% ** [[spoiler:Dmitri]] as well.
* YankTheDogsChain: [[spoiler: Enjoy your final hug and kiss, Hershel, because that's all you're going to get before your love is inevitably sucked back to her own time to die.]]
* ZanyScheme: [[spoiler: Clive's. ''And how''. Clive was somehow able to get the workers, funding,and support for his harebrained revenge scheme, despite only being about 20 years old.]]
