->''"Or perhaps in Slytherin, You'll make your real friends, Those cunning folk use any means, To achieve their ends."''

''They Shook Hands'' is a series of ForWantOfANail / AlternateUniverse Harry Potter stories written by [[http://www.fanfiction.net/u/2560219/Dethryl Dethryl]]. The first chapters were posted on the author's Yahoo!group before the release of ''[[Literature/HarryPotterAndTheOrderOfThePhoenix Order of the Phoenix]]'' in 2003. It has gained enough fame in the fandom that it was featured and discussed on Podcast/PotterFicWeekly.

The Point of Departure (for Harry, anyway) is when he meets Draco Malfoy in Madam Malkin's robe shop. In TSH, unlike canon, he introduces himself to Draco. They shake hands and decide to be friends. They spend the next month before school exchanging letters, and on the train Harry is introduced to other children Draco knows. We see Ron and Hermione, but Harry doesn't interact with them. Things really deviate from canon when Harry is Sorted into Slytherin. The story is distinct from the many other Harry-in-Slytherin fics because it doesn't turn on Harry being sorted to Slytherin but rather on Harry becoming friends with Draco.

This fanfic is an attempt to tell the big overplot of the ''Literature/HarryPotter'' series using the Slytherin characters. The functional POD is that Lucius and Narcissa Malfoy have a child before Draco, and consequently their development is slightly different. By the time Draco meets Harry, he's realized the value of friendship and is more open of a person. He's not DracoInLeatherPants, but his friendship with Harry is [[HeelFaceTurn slowly morphing]] him into a better person.

!!This fanfic provides examples of:
* AffablyEvil: Lucius Malfoy treats shopkeepers and other people he does business with politely and courteously. He even gives Flourish a Galleon after his trouble dealing with the Monster Books and tells him to buy drinks with it.
* TheAlcoholic: Hagrid. He's not really, but the main characters view his canon drinking with less tolerance than the canon characters.
* AlphaBitch: Pansy Parkinson. Laine Slater.
* AnnoyingYoungerSibling: Arcen Bulstrode. Astoria Greengrass.
* {{Animorphism}}: Sirius Black. [[spoiler: Later in the series, Harry.]]
* BigBrotherMentor: With traces of BigBrotherWorship. Harry looks up to Draco's elder brother Elan, to the point he doesn't realise Elan's large faults.
* BigBrotherInstinct:
** Elan Malfoy. He is extremely protective of Draco, and he has taken Harry under his wing as well.
** Percy Weasley. He may be a stickler for rules, [[spoiler: and have no problem turning in his siblings for committing assault on another student]], but deeply cares about his siblings, especially Ginny. When Ginny is put in danger, Percy risks his life and offers Harry anything, [[spoiler: including a valuable magical artifact and a willingness to hide Harry's crimes. When that doesn't work, Percy offers his own life, and later digs himself in further by asking for more favors for his sister. In exchange, Percy gives a magical oath to serve Harry and proceeds to be a major source of help to Harry, even breaking rules for him.]]
* BigManOnCampus: Harry, Cedric Diggory, and Viktor Krum during the Triwizard Tournament.
* BlackAndGrayMorality
* TheBully: Draco and the Slytherin kids bully Neville and Hermione for the [[EvilIsPetty pettiest of reasons]]. Harry eventually calls them out on it and comes to act as their MoralityPet.
* TheCasanova: [[spoiler: Sirius]] has the entire delegation from Beauxbatons twined around his finger at the Yule Ball.
* CatchPhrase: "Up Slytherin!" Also, TheCatchPhraseCatchesOn.
* CoolHouse: Malfoy Manor. Later on Grimmauld Place. Also BigFancyHouse
* DarkIsNotEvil: A recurring theme in the series. See HitlerAteSugar below.
* DeathByAdaptation:
** [[spoiler:Hermione is killed by the basilisk in Year 2.]]
** [[spoiler:Wormtail is given the Dementor's Kiss as a result of Snape actually listening to Harry in this timeline. May be a FateWorseThanDeath]]
* DeliberateValuesDissonance: Pureblood society
* DisproportionateRetribution: Multiple cases.
** Y1: Hagrid insults Slytherin house and Professor Snape, so the kids [[spoiler:decide they're going to hex him.]]
** Y2: Lucius essentially got Arthur Weasely fired, so in retaliation [[spoiler:Draco is nearly killed by Fred, George, Ginny, and Ron.]]
*** [[spoiler:Ginny is possessed by Tom Riddle at the time, and she's the one who escalates the incident beyond a simple beating by casting a Dark curse.]]
*** The retribution continues to escalate when [[spoiler:Percy stops them (and as a result Gryffindor loses 600 points and all four get several months of detention); he's ostracized, pranked, and eventually drugged and left hanging by his feet from the Astronomy tower.]]
* TheDon: Lucius Malfoy
* EnemyMine: [[spoiler: Lucius Malfoy and Albus Dumbledore have reached this kind of alliance based on mutual hate of Voldemort.]]
* EverybodyHatesMathematics: Arithmancy is nothing more than maths class.
* EvilOverlord: He-Who-Must-Not-Be-Named
* ExtranormalInstitute: Hogwarts, of course. Also AcademyOfAdventure, BoardingSchool, EldritchLocation, FunctionalMagic, HauntedCastle, MageTower, MagicAIsMagicA, MagicalLibrary, WizardingSchool.
* FamilyBusiness: Malfoys
* FamilyValuesVillain: Lucius Malfoy
* ForWantOfANail: Harry's first friend in the wizarding world is Draco Malfoy, not Ron Weasley. This changes the entire foundation of his introduction to the magical world.
* FreudianExcuse: [[spoiler: Theo turns into a Jerk because his Dad has been neglecting him.]]
* TheGoodTheBadAndTheEvil: Marauders, Slytherin, and Voldemort
* HeelFaceTurn: Sorta. During Harry's 2nd year, [[spoiler: Percy moves into Slytherin after being ostracized from Griffyndor. He]] subsequently becomes a much happier and more pleasant person.
* HitlerAteSugar: Slytherins very much resent being labelled Junior Death Eaters. Just because Voldemort was a Slytherin doesn't mean all Slytherins believe as he does.
* InWithTheInCrowd. Harry. Also IJustWantToHaveFriends and FriendlessBackground
* JerkWithAHeartOfGold: The Slytherin kids are very nice and supportive of Harry but that doesn't stop them from being total asshats to everyone else.
* MagicalSociety
* MakeOutPoint: The Astronomy Tower.
* ManOfWealthAndTaste: Lucius Malfoy, natch.
* MoralityPet: Harry to Slytherin House.
* {{Muggles}}: Harry is encouraged by Slytherin to express how he feels about the Dursleys. While this may be psychologically healthy, it's part of Harry's fall towards the MoralEventHorizon.
* NonIdleRich: Lucius Malfoy may be wealthy but he seems to be actively involved in government and seems to expect his sons to well educated, productive wizards. All of the Slytherins seem fairly well off and still seem to have a great deal expected of them
* NoodleIncident: Mentioned when Sirius is going to be best man at Remus and Tonks' wedding.
--> '''Sirius:''' Have I got some stories to tell. I might even finally tell everyone about the Noodle Incident.

* OneOfUs: The author is active on tvtropes, a Franchise/HarryPotter podcast (Podcast/PotterFicWeekly), and once wrote fanfiction for PowerRangers
* OurFounder: Salazar Slytherin
* OrphanageOfFear: Yet to be seen if the Magical Child Protection Act will result in this or an OrphanageOfLove
* {{Patricide}}: [[spoiler: To put it mildly, Theo and his father have a disagreement about joining Voldemort's cause.]]
* PetMonstrosity: [[spoiler: In Year 2, Harry takes control of the basilisk instead of killing it.]]
* PutOnABus:
** [[spoiler:Blaise Zabini]] is written out of the story in the Revision so that the whole series wouldn't need to be rewritten to include him. Later on, [[spoiler:TheBusCameBack]].
** [[spoiler:Hermione Granger]] is sent to Hufflepuff where she is largely out of the story. Later becomes a [[spoiler:BusCrash]].
* ThePatriarch: Lucius Malfoy. A loving one but you don't want to get on his bad side.
* ProperlyParanoid: "CONSTANT VIGILANCE!"
* ReasonYouSuckSpeech: Harry to Tom Riddle
--> Harry: "I don't fear you. I've seen what you are now: a pathetic shade, clinging to life by leeching off of others like a parasite. Whatever your plans are, I'm going to stop you, Voldemort. I stopped you eleven years ago, I stopped you last year, and I will stop you tonight! ... You are a failed and unworthy descendant of Slytherin. You're nothing more than a shade from a time long past. You are nothing. [[spoiler: I am the Heir of Slytherin!]]"
* RunningGag: "My Head is NOT FAT!"
* ScrewTheRulesIHaveConnections
* ShoutOut:
** A few Podcast/PotterFicWeekly injokes.
*** Such as?
** Author nods to other fanfics.
*** jbern - Y4 speculation about the tasks includes "Who can get closest to the dementor?" which actually happened in FanFic/TheLieIveLived. Also Y4, one line of prose reads "to fight the coming darkness", which is the title of another of jbern's fics.
*** Fanfic/AfterTheEnd - There is a throwaway line in Y4 that Lavender Brown has an older sister named Rose.
*** A Year Like None Other - Y5, when discussing how Snape can prove his loyalty to Voldemort, Snape suggests that there will be a sacrifice made at Samhain.
** ''Theatre/AVeryPotterMusical''
** ''Series/MontyPythonsFlyingCircus''
*** A few lines of one scene with Professor Sinistra appear to have been lifted from the Management Training Course sketch. WordofGod: They are.
*** Some remarks by Elan are very reminiscent of the Writers sketch. WordofGod: Again correct.
*** Also, Dumbledore sometimes acts like the Psychiatrist and uses strange turns of phrase for "Come in" and "Sit down." WordofGod: but you missed this one.
*** An early one in Y1, there is no Rule #6 in the Slytherin House rules. WordofGod: And this one.
** ''Film/ThePrincessBride'' - Several quotes slipped in very smoothly. Draco to Goyle: "Am I going mad, or did the word 'think' just escape your lips?"
** StarWars - Elan quotes Vader in Empire, "Search your feelings. You know I'm telling you the truth."
** Franchise/TheHitchhikersGuideToTheGalaxy: The lifts in the Ministry of Magic are just as happy to serve as the doors in Hitchhiker's Guide. (Just so you know, that came from a joke chapter that Dethryl posted on April Fool's Day.)
* SlouchOfVillainy: Averted. The Slytherins have an image to maintain.
* SlowlySlippingIntoEvil: Though the series isn't finished, Harry has journeyed into Darkness. It remains to be seen if he'll pull himself out before he crosses the MoralEventHorizon.
* SparedByTheAdaptation:
** [[spoiler: Cedric]]
** [[spoiler: Sirius does not fall through the Veil at the Ministry of Magic. Instead, Harry's girlfriend does.]]
* TheStationsOfTheCanon:
*** Y1: Due to the influence of outside forces, otherwise known as the plot, Harry still goes through the usual stations of The Visit To Diagon Alley, The Trip To Hogwarts, The Sorting Hat, The Troll, all the way up to The Confrontation With Quirell/Voldemort. Only how he deals with these things is different.
*** Y2: Again, many of the same points are hit. Lockhart, the Heir of Slytherin, et cetera. Some things are changed, [[spoiler: like Harry doesn't go to Sir Nick's Deathday party]], but things largely parallel canon [[spoiler: until the very end]].
*** Y3: Still very much a character story, the big plot hits familiar beats like Sirius Black, Professor Lupin, Dementors, the Patronus Charm, and so on. [[spoiler: The ending is a doozy. Sirius is proven innocent and offers Harry a home.]]
*** Y4: From Harry's perspective, the story is the same: the Triwizard Tournament comes to Hogwarts. [[spoiler: In the big finale, it is revealed that Voldemort's plot has been completely different due to the events at the end of Y3.]]
* TellMeAboutMyFather: Harry to Sirius.
* TookALevelInBadass: Harry, in comparison to his canon self, learns several spells far sooner (including the ''Furunculus'' curse, which develops into his favorite). [[spoiler:By the time the Triwizard Tournament rolls around, he is able to take the lead handily in the first two events.]]
* TookALevelInJerkass: Theo takes several levels in Year 4, [[spoiler:because his dad has been ignoring him.]]
* TrophyWife: Subverted. Narcissa and Lucius genuinely love each other and are HappilyMarried. It may also be a PerfectlyArrangedMarriage.
* UnlimitedWardrobe: Narcissa Malfoy
* WellIntentionedExtremist: Lucius Malfoy. Also EvenEvilHasLovedOnes, EvenEvilHasStandards, and NotEvilJustMisunderstood.
* WhatHappenedToTheMouse: Dobby. He not only plays a '''''much''''' smaller role than in the canon universe, he was never freed, and he is never caught attempting to 'save' Harry's life.
* WithGreatPowerComesGreatInsanity: The Malfoys believe that Voldemort started his crusade against Muggles with honestly good intentions, but the dark magic he was using gradually drove him insane.
* WouldHitAGirl: [[spoiler:Y3: Jamie Davis accuses Elan Malfoy of cheating on her and tries to hex him. She gets off three spells, which he blocks, before he uses a spell that breaks all the bones in her wand hand.]]
* ZeroPercentApprovalRating: It seems like a large chunk of the Death Eaters have left the Dark lord in favour of a more kindly Heir of Slytherin.
Dethryl revised the story following the completion of canon but has left the original version posted for posterity. This is the version of the story covered on Podcast/PotterFicWeekly.
