The Sheriff's daughter, Abby's mother was murdered by John Wakefield in the 2001 massacre. Her father sank into a deep depression after this and sent Abby to live with her grandmother in L.A. Seven years later, she returns to Harper's Island to celebrate her best friend Henry's wedding. [[spoiler:She is the central motivation for the Wakefield-Dunn killings. Henry betrays his father and mentor in order to fulfill a ChildhoodMarriagePromise made years before. Did we mention Abby is Henry's half-sister? Well, she is. Abby survives the massacre.]]

----

* BloodSplatteredWeddingDress: When [[spoiler: Henry kills her]].
* BreakTheCutie: Trish shuts down emotionally after watching [[spoiler: her father die.]]
* CharacterDeath: [[spoiler: Henry stabs her in the side]].
* CharacterDevelopment: Her [[spoiler: father's death pushes Trish into an almost catatonic state]]. Abby talks her out of it, though, and Trish ends up becoming very proactive in the show's second act.
* DaddysGirl: She is devoted to her father and is much more upset than Shea when [[spoiler: he dies]].
* FinalGirl: [[spoiler: Averted, but she makes it pretty far regardless and is the last female victim]].
* HiddenDepths: She initially appears as a not-so-intelligent rich girl with overly romantic ideals. Turns out she can take care of herself, use a shotgun without much trouble, and is one of the characters who truly takes charge in the last act.
* TheLeader: When Henry wasn't with the group Trish would take over as unofficial leader. She even acts as a big sister towards Shea, even though Shea is older.
* MsFanservice: Doesn't flaunt it around like Chloe does, but it's still there.
%% * SpoiledSweet: A genuine sweet person, averting the stereotypes usually brought up with rich characters.

[[caption-width-right:180: ''"It's happened here before, and it's happening again. We're being picked off one by one."'']]

* HiddenDepths: Much cleverer than she appears, and not quite as vapid.
* MsFanservice: She ends up in her underwear exponentially more than any other woman in the show. Which makes sense, since she's 'the flirt' and all that.
* NightmareFetishist: She has a fascination with the Wakefield murders, though once she's actually surrounding by Wakefield murders she becomes quickly disenfranchised.
* SingleWomanSeeksGoodMan: It's implied that she loves Cal so much because he treats her like a real person, unlike her numerous other boyfriends.
* TheTease: Flirts with Marty and Sully but is really devoted to Cal.

----
* BetaCouple: Half of it, with Chloe.
* HairOfGoldHeartOfGold
* ImpaledWithExtremePrejudice: [[spoiler: How Wakefield kills him]].

* TheMedic: Patches up Charlie's spear-wound and Henry's injured leg, though he professionally works only on dead people.
* NerdsAreSexy: His appeal. Both Chloe and Stacey the Stripper point it out.

[[caption-width-right:180: ''"Abby Mills...I knew you'd be here."'']]
Abby's high school sweetheart and ex-boyfriend. He never quite got over her leaving so suddenly after the Wakefield murders and is intent on reconnecting with her when she's in town for the wedding. [[spoiler:He is one of the four survivors of the series, escaping with Abby.]]

----
* NotQuiteDead: [[spoiler: He is presumed dead in the marina explosion, but this is disproved not long after when his unconscious body is delivered to the Cannery.]]
* OddFriendship: Two, actually. He's friends with Charlie, who didn't really like him when he was dating Abby. He's also friends with local {{Jerkass}} Shane who he works with and defends at all costs.
* NiceGuy: Amiable and friendly, he gets along with just about everyone he has screentime with, and sticks by his friends to no end. Mixes with DoggedNiceGuy in his pursuit of Abby.
* PromotionToOpeningTitles: In Episode 5.
* RedHerring: [[spoiler: He is the third character to be outright made a suspect, and it's implied to be the only reason Wakefield let him live that long.]]
* SatelliteLoveInterest: He doesn't really have much personality outside of wanting to get back with Abby. Shane even calls him out on it once or twice.
* TheScapegoat: [[spoiler: Henry intended him to serve this purpose, signing a confession to the murders so he and Abby could live their 'happily ever after' on the island, presumed dead.]]

[[caption-width-right:180: ''"It's Wakefield's game. He takes the ones we love, and picks us off one by one."'']]

----

* ForYourOwnGood: His initial justification for sending Abby away, which he later regrets.

* NeckSnap: [[spoiler: Wakefield's deathtrap hangs him]].
* OddFriendship: With his daughter's ex-boyfriend Jimmy. They meet every week for breakfast.
* ReasonableAuthorityFigure: He mostly defies the horror movie cliche of PoliceAreUseless, although this is zigzagged at points.

* RubeGoldbergHatesYourGuts: [[spoiler: Wakefield puts him in an elaborate deathtrap that is designed to snap his neck. It works]].

!!Thomas Wellington: The Father of the Bride
->'''Played by:''' Creator/RichardBurgi
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/thomas_wellington.jpg]]
[[caption-width-right:180: ''"My daughter's not marrying Henry Dunn."'']]
[[ExactlyWhatItSaysOnTheTin Trish's father]], and the CEO of a major commercial real estate firm. He is a self-made man, and the ultimate {{Determinator}}, completely committed to getting what he wants, including stopping his youngest daughter's wedding. [[spoiler:He is killed with a head spade booby trap during the wedding rehearsal in Episode 5. His death is a major turning point in the series, and officially closes off the 'happy and carefree' part of the show.]]

----
* CorruptCorporateExecutive: Not in his actual business, per se. It's just that he applies a lot of the same tactics to his family life.
* CassandraTruth: Tells Trish in Episode 5 that he doesn't trust [[spoiler: Henry]] based on "instinct". [[spoiler:He's absolutely correct in these assumptions.]]
* DeathByLookingUp: [[spoiler: Looks up just in time to see the head spade come down on his face]].
* GiveAwayTheBride: His role in the wedding ceremony of course, and the manner of his death in the rehearsal.
* ImpaledWithExtremePrejudice: [[spoiler: His death is this trope]].
* JerkWithAHeartOfGold: Very cold to most people, but he's fiercely protective of his daughter. He also becomes a lot more likeable in retrospect when you realize [[spoiler: he was totally right about not trusting Henry]].
* ThePatriarch: Of the Wellington clan. One of the reasons [[spoiler: his death is so jarring]].
* SacrificialLion: [[spoiler: His death is a major turning point in the show, and it lets the characters know there's a killer on the loose]].
* SurprisinglySuddenDeath: [[spoiler: His death is very sudden and shocking, especially to the characters since by that point they didn't even know there was a killer on the island]].

!!Hunter Jennings: The Other Man
->'''Played by:''' Creator/VictorWebster
Trish's ex-boyfriend from college who, [[NoodleIncident was apparently scared off by Henry after the couple broke up]]. However, [[spoiler: Daddy Wellington is paying him to come back to the island in order to break up the relationship between Henry and Trish]]. He finally gives up and is paid an extra fee by Mr. Wellington to leave the island...[[spoiler: and is killed by a rigged shotgun planted in his boat.]]

----
* AffablyEvil: Not "evil" per se, but he's absolutely charming and handsome to people who don't know him well.
* AssholeVictim: [[spoiler: Definitely had it coming.]]
* BoomHeadshot: [[spoiler: Courtesy of a rigged shotgun]].
* ChekhovsGun: After [[spoiler:he dies]], the discovery of his boat sets off a subplot involving Malcolm and the rest of the groomsmen.
* {{Filler}}: His character and its associated subplot is only around for the first three episodes (and very briefly in the first two, at that). Hunter's whole character is a RedHerring, and [[spoiler: his death]] only serves to set up the groomsmen bag of money storyline.
* {{Jerkass}}: He's a total asshole.
* MauveShirt: [[spoiler: Dies in Episode 3]].
* MockMillionaire: Originally supposed to be this, but the scene revealing it was cut for time. Hunter family was supposed to have disinherited him for some indiscretion, which would have necessitated his dependence on Mr. Wellington's money. Katherine would have showed Thomas this information, which would have led to Hunter's expulsion from the island.
* {{Narcissist}}: He loves no one but himself, and really couldn't care less about Trish, so long as he gets paid.
* NoodleIncident: Whatever exactly happened 'in college' that led to Trish breaking up with Hunter and returning to Henry. It was presumably very unpleasant.
* StalkerWithoutACrush: Crosses over with OnlyInItForTheMoney.
* WhatHappenedToTheMouse: Something of a meta example. He is the only character among the [[spoiler: 'early outs' to never be mentioned after his death]]. Probably because so few characters knew he was on the island, and the ones who [[spoiler: found his body]] didn't know who he was.

!!J.D. Dunn: The Black Sheep
->'''Played by:''' Creator/DeanChekvala
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/jd_dunn.jpg]]
[[caption-width-right:180:''"I've got one last surprise for you, Henry. I think you're really gonna like it."'']]
Henry's unstable younger brother. Suicidal, outcast, and antisocial, he was extremely shaken by his parents' deaths and finds it difficult to connect with anyone after that. [[spoiler: He is killed by Henry in Episode 8, and it is heavily implied that killing J.D. was most difficult for Henry.]]

----
* BadButt: He doesn't really do anything 'disturbed' or 'crazy' unless he's provoked. Outside of that, the worst he really does is set off firecrackers with a nine-year-old girl.
* BarBrawl: With Shane in Episode 1. Abby breaks it up.
* BirdsOfAFeather: With Kelly.
* CainAndAbel: [[spoiler: He is murdered by his own brother. Although technically Henry isn't ''really'' his brother...]]
* CharacterDeath: [[spoiler: Henry stabs him]].
* ClearMyName: When he becomes a chief suspect in the murders, he leads a short-lived investigation with Abby and Henry to prove that [[spoiler: Wakefield]] is still alive and killing again.
* GuttedLikeAFish: [[spoiler: How he dies, and on the docks to boot.]]
* IcyBlueEyes: He has them.
* LonersAreFreaks: A tragic part of his character.
* OddFriendship: With Madison. He's her only friend on the island. [[spoiler: Well, besides Wakefield...]]
* RedHerring: [[spoiler: The second character to be explicitly made a suspect]].
* SuicidePact: Had one with his girlfriend. It didn't exactly work however, and J.D was saved while his girlfriend died.
* TattooedCrook: While not a 'crook' per se, J.D is covered in tattoos to emphasise his rebellious antisocial nature.
* TroubledButCute: He's still pretty likable despite his issues.
* UsedToBeASweetKid: According to the flashback in Episode 13.

!!Christopher "Sully" Sullivan: The Best Man
->'''Played by:''' Creator/MattBarr
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/christoper_sullivan.jpg]]
[[caption-width-right:180:''"This is really gonna suck."'']]
The best friend of Henry Dunn, and best man at his wedding. [[spoiler: He is fatally stabbed by Henry in Episode 13, and officially the last of the wedding guests to die.]]

----
* TheCasanova: He chased Trish in college, chases after Chloe in the early episodes, clearly wouldn't mind spending some time with the other bridesmaids, has been trying to sleep with Abby for years and even snags a quick NowOrNeverKiss from Nikki. However...
** CasanovaWannabe: He never actually gets together with anyone, despite his efforts. Of the principle male characters he's the only one without a love interest of some kind.
* CharacterDevelopment: He has the most definite character arc of the 25 characters. As a matter of fact, he gets more character growth than some of the principles.
* ChildhoodFriends: With Henry. One of the reasons [[spoiler: Henry's confession breaks him so badly]].
* DirtyCoward: When Madison is kidnapped, Sully is the most vocal about leaving her behind in favor of going home, going so far as to attempt escape with Cal, Chloe, and Beth.
* FourTemperamentEnsemble: Among the groomsmen, he's Choleric.
* {{Fratbro}}: At first, but he develops HiddenDepths.
* GetAHoldOfYourselfMan: Trish does that to Sully when doesn't care about Madison's life.
* HeterosexualLifePartners: With Henry, and to a lesser extent Danny.
* InTheBack: [[spoiler: Literally and figuratively by his best friend]]
* {{Jerkass}}: At first.
** JerkWithAHeartOfGold: After CharacterDevelopment.
* TheLancer: In the latter half of the show, Sully takes this role, occassionally sharing it with Jimmy.
** TheLeader: Of the groomsmen.
* RedemptionEqualsDeath: [[spoiler: He lets Shea and Madison leave the island without him, intending to stay behind until Henry gets back. Ironically, Henry is secretly the murderer and ends up killing him]].

!!Marty Dunn: The Uncle
->'''Played by:''' Creator/HarryHamlin
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/marty_dunn.jpg]]
[[caption-width-right:180:''"Love is a funny thing, isn't it?"'']]
Henry and J.D.'s [[ExactlyWhatItSaysOnTheTin uncle]], and J.D's legal guardian since his parents' deaths. He's fun-loving and acts much younger than he is, and is completely devoted to Henry and his impending wedding. [[spoiler: He is killed in the first episode, and is the first of the 25 characters to die.]]

----
* BriefcaseFullOfMoney: Marty brings a bag of $250,000 dollars to the island, which changes hands several times following [[spoiler: his death]].
** In Episode 13 [[spoiler: Henry reveals that the money was supposed to be for Malcolm to help him start up his brewery. He planted the bag on Hunter's boat with the intent of Malcolm finding it, just ForTheEvulz]].
* TheCasanova: Very much a skirt chaser. He's only shown on screen with Chloe, but he's apparently such a hit with the ladies that a random fling is a believable enough excuse to explain his absence once [[spoiler: he's dead]].
* CharacterDeath: [[spoiler: Wakefield ensures that he doesn't last the first episode]].
* {{Cool Old Guy}}: A mild example, but a good one nonetheless
* {{Cool Uncle}}: To JD and Henry. [[spoiler: Well, actually only JD]]
* DeadStarWalking: [[spoiler: One of the biggest names in the cast, he's dead by the end of the first episode]].
* ExactEavesdropping: He overhears Thomas conspiring with Hunter about breaking up the wedding, making him one of a very select group of people who knew Hunter was on the island. Of course, [[spoiler: He's killed that same night, before he can do anything about it.]]
* FloorboardFailure: [[spoiler: As he's crossing a footbridge in the woods, the boards suddenly give out underneath him, allowing him to be neatly cut in two]].
* {{Foil}}: To Mr. Wellington.
* {{Half the Man He Used to Be}}: [[spoiler: Bifurcated on a bridge, thanks to John Wakefield]]
* HonoraryUncle: He insists everybody call him 'Uncle Marty', whether they like it or not.
* LargeHam: Probably why he's a fan favorite despite [[spoiler: only appearing the the first episode]].
** IncomingHam: His first scene has him show up with a Mariachi Band, doing a Mexican hat dance, screaming "Olé!" at the top of his lungs and declaring that "For the entire week, it's gonna be Uncle Marty for everyone!"
* LifeOfTheParty: See IncomingHam.
* RedHerring. Everything to do with his character, really. The bag of money, the gun, his business in 'sales', his determination to see the wedding happen... This makes [[spoiler: his death]] in the first episode all the more shocking.
* SecretKeeper: A possible interpretation is that Marty was the only one who knew [[spoiler: that Henry was adopted.]] It could very well explain why he was killed so early on, before suspicion could take root.
* {{We Hardly Knew Ye}}: [[spoiler: The first of the 25 major characters to die]].

!! Shea Allen: The Maid of Honor
-> '''Played by:''' Creator/GinaHolden

[[caption-width-right:180: ''"Couples shouldn't have secrets."'']]
Trish's big sister and the matron of honor. [[spoiler: She escapes the island with Madison in Episode 13 and is one of the four survivors of the massacre]]

----
* ActionSurvivor: [[spoiler: Survives to the end of the series, along with her daughter, Abby, and Jimmy]].
* BreakTheCutie: By the end of the series she's [[spoiler: lost her father, husband, stepmother, sister, and many of her close friends]].
* TheGenericGirl: She doesn't really get a great deal of depth.
* TheLoad: Doesn't contribute a whole lot to the group, although unlike her daughter she never gets any NiceJobBreakingItHero moments.
* {{Housewife}}: Is implied to be this, as her husband works a very demanding corporate job.
* MamaBear: Very protective of Madison, to the point where she unwittingly hinders several important revelations in the third act.
* MissingMom: Like Trish, her mother died a few years before the story starts. She isn't quite as resentful of her new stepmother Katherine, though.
* ProperLady: Refined, elegant and very polite, contrasted with her sister less proper sister Trish.
* SlipKnotPonytail: A tamer variation. As the situation worsens, Shea's very severe ponytail begins coming undone. [[spoiler: By the time she escapes the island, it's a wild, tangled mess].
* SoleSurvivor: Sort of. [[spoiler: She's one of the only four survivors]].
* TraumaCongaLine: A particularly brutal one, which crosses into TakeThatScrappy for some fans. Within a space of 24 hours she [[spoiler: watches her father die, learns about her husband's affair with her stepmother, discovers her daughter is kidnapped and learns that her husband is dead and her daughter is being held for ransom.]]

!! Richard Allen: The Brother-in-Law
-> '''Played by:''' Creator/DavidJamesLewis
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/richard_allen.jpg]]
[[caption-width-right:180: ''"Ah, the velvet straitjacket of being a Wellington."'']]
Shea's husband, Madison's father, and Thomas's long-time right hand man in the business world. More cautious and reserved than his father-in-law, Richard has a tendency to appear somewhat meek and maybe even pathetic, to those that don't know about his secret ways of coping. [[spoiler: Richard is [[ImpaledWithExtremePrejudice harpooned]] in ''Sploosh'', shortly after Trish exposes his affair with Katherine.]]

----
* AssholeVictim: [[spoiler: While he wasn't the biggest asshole on the show, he was definitely marked for death after his affair was revealed]].
* BondageIsBad: Richard isn't exactly portrayed in a sympathetic light, and his BDSM session with [[spoiler: Katherine]] in Episode 4 is portrayed as something quite sinister.
* CasanovaWannabe: He has an implied flirtation with Lucy in Episode 2 and quite noticeably is oogling Chloe under Cal's nose in Episode 3. His efforts get him nowhere, which undoubtedly fuels his inferiority complex.
* DivorceAssetsConflict: Richard was clearly anticipating custody troubles with Madison after [[spoiler: the affair was exposed]]. He's on the phone with his lawyer when he [[spoiler: is killed]].
* ExtremeDoormat: Is convinced Thomas sees him this way. Judging by one conversation between Thomas and an elderly wedding guest in ''Ka-Blam'', he may be right.
* ImpaledWithExtremePrejudice: [[spoiler: Henry shoots him with a harpoon gun]].
* {{Jerkass}}: He's quite the asshole, [[spoiler: cheating on Shea with little regard to how it'll affect her and his daughter]].
** JerkWithAHeartOfGold: A possible interpretation of his character, as his love for Madison is genuine.
* KilledMidSentence: [[spoiler: Richard is harpooned while talking to his lawyer on the phone. The killing blow cuts him off, apparently as he was discussing obtaining shared custody of Madison.]]
* RedHerring: Briefly becomes a suspect, although [[spoiler: these concerns are put to rest when he dies in episode 6]].
* {{Revenge}}: His reasons for [[spoiler: sleeping with Katherine are mostly rooted in sticking it to Thomas rather than betraying his wife]].
* VillainousRescue: When he saves [[spoiler: Trish from the closing pool]] in Episode 4. This crosses over into DeusExMachina as he sort of just comes out of nowhere with an unsettling rapidity.
* WhatHappenedToTheMouse: The articles on the Wakefield murders he requested from Harper's Globe. Katherine shows them to Charlie in Episode 6, which suggests Richard might be the Wakefield copycat. However, [[spoiler: he dies the same episode and the articles are never brought up again]].

[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/madison_allen.jpg]]

The young daughter of Shea and Richard, Madison is a somewhat withdrawn, socially awkward little girl. Though she isn't much of a problem child, she has strange interests and hobbies...and not even her parents are ever entirely sure what she's up to. [[spoiler: She is kidnapped by John Wakefield to keep the others from leaving the island. Post rescue, she manages to escape the island along with her mother.]]

----
* ActionSurvivor: [[spoiler: Makes it out alive]].
* BreakTheCutie: By the end [[spoiler: she's lost almost everyone close to her]].
* CanNotSpitItOut: She knew [[spoiler: Wakefield was alive from the beginning, but doesn't reveal anything until it's too late.]] She also lies to everyone [[spoiler: on Wakefield's orders, turning everyone against Sheriff Mills]] because it's part of 'the game'.
* CreepyChild: She can come off as ''really'' creepy, to the point where it seems like she knows more about what's going on than the others.
* CreepyMonotone: She slips in and out of one throughout the series.
* DeadPersonConversation: In Episode 4, Madison claims that 'the spirits' told her there wasn't going to be a wedding. However, [[spoiler: it is more likely that it was Wakefield she was talking to, and she merely believed she could talk to ghosts]].
* KidsAreCruel: She's awfully spiteful beneath all of her CreepyChild tendencies. She kills small animals, rips up flower beds and, according to Katherine, often hides from her parents to get attention.
* TheLoad: Not only is she useless, but she causes some problems as well (see NiceJobBreakingItHero).
* NiceJobBreakingItHero: Caused several deaths by withholding information from the group because she was "scared".
* NoSocialSkills: She is very forthright and direct, when she's not [[CanNotSpitItOut withholding life-saving information]], as is most apparent through her friendship with J.D.
* NotNowKiddo: When the gang is holed up in The Cannery, Madison [[spoiler: sees Wakefield approaching]]. She tries to warn the others but gets this response. [[spoiler: Nikki ends up dead not a minute later]].
* SoleSurvivor: Sort of. [[spoiler: She's one of the only four survivors]].
* TagalongKid: The only child in the cast.

!! Katherine Wellington: The Stepmother
-> '''Played by:''' Creator/ClaudetteMink
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/katherine_wellington.jpg]]
[[caption-width-right:180:''"I loved your father. I may have done some foolish things, but I didn't kill him."'']]

Thomas's second wife, barely older than Shea. Beautiful, confident and with a warm, self-effacing personality, Katherine is the cut-out image of the perfect trophy wife. And, though she may be comfortable playing accessory to a wealthy businessman, Katherine has deeper desires that her money and influence can't quite satisfy. [[spoiler: After her affair with Richard is exposed, Katherine is shunned by her stepdaughters and most of the rest of the party. She is stabbed in the back and left to bleed out in ''Seep''.]]

----
* TheAtoner: After [[spoiler: her affair is exposed, Madison is kidnapped and Richard is found dead]], Katherine does try a few times to make up for her crimes against her stepdaughters. She helps Trish and Shea make tea, tries to assure her that Madison will be found, and attempts to keep Shea from going out and doing something rash in the search for her daughter, to no avail.
* BondageIsBad: While Katherine isn't as outright vilified for her part in the affair, she is still scene as an object of disdain by Trish, and her BDSM session in the basement is portrayed in a sinister manner.
* DefrostingIceQueen: One interpretation of her softer, gentler characterization once [[spoiler: her affair]] is exposed.
* DumbStruck: Evidently the case after watching [[spoiler: Thomas being impaled]] during the wedding rehearsal. Katherine is in a state of mute shock, sitting still while everyone else goes outside. Sheriff Mills has to help her stand.
* InTheBack: [[spoiler: Is stabbed in the back with pruning shears by Henry, through a couch no less.]]
* JerkWithAHeartOfGold: Despite [[spoiler: her affair with Richard]], She genuinely cares about Thomas and Madison. She tries to explain this to Trish and Shea, but they rebuff her for obvious reasons.
* KilledOffScreen: [[spoiler: Is murdered offscreen by Henry, apparently with Shane in the room and none the wiser until he turned around and saw her bleeding out.]]
* LadyDrunk: She hits the bottle hard after the affair is exposed.
* LonelyTogether: With Shane in ''Seep''. They share a drink at the bar and evidently got along well enough to keep each other company while everyone was running around not trusting them. [[spoiler: Shane is the only witness to her death because of this.]]
* MauveShirt: She never really gets much screentime or personality [[spoiler: before dying]].
** Indeed, while Richard's motivations for engaging in the affair are stated clearly to be {{Revenge}} against Thomas for mistreating him, Katherine's motives are never even brought up, though it is implied she may simply have been bored in her marriage, and Richard was just an outlet for excitement.
* MayDecemberRomance: With Thomas, though the 'romance' part is debatable.
** According to the list of bridal party members Shea gives to Karina for the bachelorette party, Katherine is barely a week older than Shea.
* TrophyWife: Her whole aesthetic, of course.

!! Danny Brooks: The College Buddy
-> '''Played by:''' Creator/BrandonJayMcLaren
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/danny_brooks.jpg]]
[[caption-width-right:180:''"I think we could use a prayer."'']]

A groomsman and, like Sully, Malcolm and Booth, one of Henry's fraternity brothers. Danny is less easygoing than Sully and Malcolm, and more drive and confident than Booth. He likes to get along with people,and it would be pretty difficult to get on his bad side.

----
* BlackDudeDiesFirst: Totally averted. [[spoiler: He dies in the penultimate episode]].
* DespairEventHorizon: Experiences this when he, Abby and Henry [[spoiler: return to the Cannery to find Nikki and Shane dead, and the others missing]]. Abby encourages him to keep on going.
* DyingMomentOfAwesome: [[spoiler: He does ''not'' go down easy. Wakefield even acknowledges that he put up a good fight]].
* EyeScream: [[spoiler: Wakefield impales him through the eye with a memo holder]].
** In the previous episode, Danny is almost run through the eye with a metal pole while he and Sully barricade the tunnel entrance in the Candlewick kitchen. [[spoiler: It's possible Wakefield improvised Danny's eventual death because of this moment.]]
* FourTemperamentEnsemble: Among the groomsmen, he's Phlegmatic.
* TheGenericGuy: Sadly, although Danny is around for a while he never gets much personality aside from being nice.
* HeroicSacrifice: [[spoiler: Fights Wakefield to allow Shea and Madison to escape]].
* TheLancer: Of the groomsmen, next to Sully as {{The Leader}}, Malcolm as {{The Funny Guy}} and Booth as {{The Smart Guy}}.
* LaserGuidedKarma: He confides to Henry that he believes the wedding party is on the receiving end of this for taking the bag of money off the boat. Henry rebuffs this, saying he doesn't believe life works that way. [[spoiler: Henry would know, of course.]]
* NiceGuy: One of the nicest characters on the show.
** BewareTheNiceOnes: See UnstoppableRage.
* TokenMinority: At least he doesn't [[BlackDudeDiesFirst die first]].
* UnstoppableRage: He goes berserk when Malcolm confesses to [[spoiler: accidentally getting Booth killed]].

!! Malcolm Ross: The Hustler
-> '''Played by:''' Creator/ChrisGauthier
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/malcolm_ross.jpg]]
[[caption-width-right:180:''"I thought...if you guys thought Booth ran away with the money...maybe I could keep it."'']]
One of the groomsmen and, like the others, one of Henry's frat brothers. Malcolm was a quintessential party animal in college and, after graduating, sought to turn his love of indulgence into a career, trying to get his home microbrewery Sacred Turtle off the ground. He hasn't been that lucky though, and is now more desperate than he'd like his friends to know.

----
* AbortedDeclarationOfLove: Seems to be what happens in ''Thrak, Splat, Sizzle'', when Malcolm is too busy trying to hide the money to spend a minute or two talking with a tragically disappointed Beth.
* DisposingOfABody: When [[spoiler: Booth shoots himself]], Malcolm buries him in the woods. He ends up being killed before he can reveal where he put the body.
* FourTemperamentEnsemble: Among the groomsmen, he's Sanguine.
* TheFunnyGuy: Of the groomsmen, next to Sully as {{The Leader}}, Danny as {{The Lancer}} and Booth as {{The Smart Guy}}.
* {{Greed}}: Malcolm is so consumed by his debt and his lack of success in business that he clings to the ill-gotten $250,000 even after [[spoiler: his pursuit of it causes Booth's death]]. However he attempts to justify it afterward, Malcolm did all he could to keep the truth quiet, in hopes he could keep the money.
* HeelFaceDoorSlam: [[spoiler: Just when he decides to man up and burn the money, he is murdered]].
* IDidWhatIHadToDo: He is deep in debt and uses it as an excuse to take the suitcase full of money in Hunter's boat.
* LifeOfTheParty: He brings his own beer, is full of laughs, and looks forward to the debauchery of the bachelor party, though he is unfortunately unable to attend it.
* MyGodWhatHaveIDone: He is plagued with guilt after [[spoiler: accidentally getting Booth killed]].
* NiceJobBreakingItHero: So many problems could have been avoided if he didn't take the bag of money from Hunter's boat. Namely, [[spoiler: Booth wouldn't be dead]].
* OffWithHisHead: [[spoiler: His head is chopped off and thrown into the fire]].
* StepfordSmiler: His funny guy, party animal veneer is all a projection to hide a very desperate and depressed man who just can't get a break financially.
* ThereIsNoKillLikeOverkill: [[spoiler: He is hacked to pieces by Henry, and his head and limbs are tossed into an incinerator]].

!! Joel Booth: The Nerd
-> '''Played by:''' Creator/SeanRogerson
One of the groomsmen, and therefore part of the same frat from college. Booth is something of a hypochondriac, and his seasickness and social awkwardness make him a subject of good-natured ridicule from his friends.

----
* ButtMonkey: Things really don't go well for him.
* ADeathInTheLimelight: [[spoiler: Is a bit character in the first three episodes, and then finally gets a POV in ''Bang''...where he dies.]]
* ForgottenFallenFriend: Of a sort. [[spoiler: After Malcolm confesses the truth of Booth's death to Sully and Danny, they arrange to tell the Sheriff. Malcolm is killed shortly afterward, and neither Sully nor Danny ever bother mentioning Booth's death to anybody else]].
* FourTemperamentEnsemble: Among the groomsmen, he's Melancholic.
* {{Hypochondria}}: His character bio styles him as one, though the only element of hypochondria Booth displays is his seasickness.
* IJustShotMarvinInTheFace: [[spoiler: He accidentally shoots himself in the leg with his gun when Malcolm surprises him. While he doesn't feel anything at first, he abruptly collapses and bleeds to death]].
* MauveShirt: Little more than a background character in the first three episodes, he gets some characterization in ''Bang'', [[spoiler: before dying]].
* NervousWreck: Becomes one during the debacle with the money.
* OnlyAFleshWound: [[spoiler: Averted; while it took a minute for him to die that shot to the leg was fatal]].
* TheSmartGuy: Of the groomsmen, next to Sully as {{The Leader}}, Danny as {{The Lancer}} and Malcolm as {{The Funny Guy}}.

!! Beth Barrington: The Single Girl
-> '''Played by:''' Creator/AmberBorycki
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/beth_barrington.jpg]]
[[caption-width-right:180:''"I hate this place."'']]

Trish's college roommate. A scholarship student with not a lot of private means, Beth is also quieter and more withdrawn than her boisterous, beautiful friends. Regardless of their social differences, however, Beth is comfortable in the extravagant world of the Wellingtons, though she can't always hide how much she'd like a piece of it for her own.

----
* AbortedDeclarationOfLove: Seems to be what happens in Episode 7, when Beth comes up to Malcom's room to thank him for comforting her, and Malcolm is too busy trying to hide the money to spend much time with her.
* BreakTheCutie: Happens in full force post-headspade. Once the murders come to light, Beth is struggling to hold it together, with her best friend Lucy missing and doesn't know anyone enough to confide in. She becomes desperate to leave the island but is forced to stay when Madison goes missing.
* TheCutie: Once the situation takes a turn for the worse, Beth begins hanging around the groomsmen, possibly because of her crush on Malcolm.
* FormerlyFat: according to one of the deleted scenes, when she's spending time with Malcom.
* TheGenericGirl: See RedShirt.
* HalfTheManHeUsedToBe: [[spoiler: Danny only finds half of her body, minus an arm]].
* NiceGirl: From her limited screentime, she seems to be pretty pleasant.
* KilledOffscreen: [[spoiler: She goes missing and her bisected corpse is later found by Danny]].
* LivingProp: She appears in all nine episodes before her death, but has no lines in two of them and minimal roles in every other episode.
** She has a brief story arc regarding a flirtation with Malcolm, and a growing sense of despair as the situation on the island gets worse, but neither one comes to anything.
* RedShirt: The biggest on the show. She sticks around for a good portion of the show but despite this, she practically blends into the background and has literally no personality or discernible character traits. It became a MemeticMutation in the fandom to say "who the hell is Beth?" when she goes missing.
* ShrinkingViolet: A possible in-universe explanation for her always hanging about in the background, never saying very much. She's only sort of comfortable around Trish and Lucy, and it takes her awhile to get used to the others.
* TomboyAndGirlyGirl: The Tomboy to Lucy's Girly Girl, if only for the fact that she plays around with the groomsmen more than the other ladies.
* TrailOfBlood: [[spoiler: When Beth is discovered to be missing, the others follow implausibly long trails of blood into the bootlegging tunnels, inevitably leading to the crawlspace she died in.]]
** It's suggested that [[spoiler: not all of the blood is Beth's own, and Wakefield used other samples as red herrings just to split the groups up]].
* WhatYouAreInTheDark: she briefly does succumb to panic try to ScrewThisImOuttaHere with Cal, Chloe and Sully, but changes her mind, along with Chloe, after being reminded by Cal that they'll be dooming Madison if they go.

A bridesmaid, and Trish's best friend from growing up. The Daramours and Wellingtons used to summer on the island together, though Lucy never developed as much of an attraction to the place as Trish did. Lucy is confident, beautiful and not afraid of showing it off, despite her happy relationship with her boyfriend back home.

----
* CanineCompanion: Her teacut/poodle mix, Gigi. She carries her around wherever she goes.
* DumbBlonde: Averted. Of Trish's friends, Lucy is the only one who ever sits her down and talks to her heart-to-heart, [[spoiler: despite being the first of those friends to bite it]].
* DeathByLookingUp: [[spoiler: She gets stuck in a pitfall and looks up just in time to be doused in kerosene and set on fire.]]
* FriendToAllLivingThings: Is very attached to her dog.
* ForgottenFallenFriend: [[spoiler: Her absence isn't even mentioned at the bachelorette party]].
** This is due to a deleted scene that would have shown Lucy planning to visit her boyfriend on the mainland briefly, before returning for the wedding. However, it was cut so Lucy's absence remains unnoticed for three episodes after her death.
* HiddenDepths: Her character bio mentions that she is studying law.
* KillItWithFire: [[spoiler: Wakefield sets her on fire]].
* {{Polyamory}}: Believes in this principle. When she contemplates having a fling with one of the groomsmen, she tells Beth that 'eating ain't cheating'. Whether or not her boyfriend Ryan approves of this sort of thinking remains a mystery.
* {{Socialite}}: Her 'nickname' in the show's advertising. Lucy is a social butterfly, equally comfortable with the rich and privileged Trish and the lower class Beth.
* TomboyAndGirlyGirl: The Girly Girl to Beth's Tomboy.
* WeHardlyKnewYe: The only memorable traits she had was her tiny dog[[spoiler: and her fiery death in the second episode. Even the dog stuck around much longer than she did.]]
* UncertainDoom: [[spoiler: One of the only characters whose death has even the slightest ambiguity, as she's last seen still alive, thrashing around while on fire, but isn't engulfed to the point where she couldn't have put out the flames by stopping, dropping and rolling. Even if she did survive the initial fire though, she would have spent days exposed, suffering from her burns, days in which no one found her, making her survival extremely unlikely]].

* TheBully: To JD.

* HeroicSacrifice: [[spoiler: Fights Wakefield so that the others can get away. After being impaled, he uses his last ebb of life to distract Wakefield once more so that Trish and Chloe can sneak through a window]].
** RedemptionEqualsDeath: [[spoiler: All of this was pretty surprising considering how much of a dick he had been earlier]].
* ImpaledWithExtremePrejudice: [[spoiler: His ultimate fate, though...]]
** NotQuiteDead: [[spoiler: He barely survives and uses the little strength he has left to distract Wakefield again]].
** KilledOffScreen: [[spoiler: When the group returns to the bar they find Shane, dead and strung up]].
* {{Jerkass}}: He's an aggressive jackass to just about everyone.
** JerkWithAHeartOfGold: However, in the end he proves himself to be good at heart when he [[spoiler: pulls a HeroicSacrifice]].
* KickTheDog: Mocks JD's suicide attempt and the death of Abby's mother.
* LibationForTheDead: When [[spoiler: Jimmy is presumed dead in the marina explosion]] Shane helps himself to a bottle of scotch at the Cannery. When Henry asks him why he's drinking it if he doesn't like it, Shane says that Jimmy drank scotch and he's drinking in his memory.
* LonelyTogether: Shane and Katherine share a few drinks at the Candlewick bar in Episode 9, shortly before Katherine's death.
* OddFriendship: With Jimmy, considering Jimmy's a NiceGuy and Shane's a {{Jerkass}}.
* WrittenInAbsence: Is absent for a few episodes after getting arrested, though he's back by Episode 8.

Shane's ex-girlfriend. Her mother, Kate, was one of the victims of the 2001 Wakefield massacre, and Kelly never fully recovered mentally or emotionally. She wants nothing more to escape the island, but there always seems to be something getting in her way.

----
* BrokenBird: Her mother's death kicked off a series of misfortunes for her, making her a local outcast and leading to several suicide attempts.
* CassandraTruth: [[spoiler: Everyone thought she was crazy when she claimed Wakefield was still alive.]]
* DomesticAbuse: Was abused by her boyfriend Shane, before and after they broke up. When Nikki tried to convince her to get a restraining order against Shane, Kelly refused.
* {{Goth}}: Her wardrobe and makeup reflect this.
* HopeSpot: Abby agrees to let Kelly live with her in L.A., she hooks up with J.D., and even calls this the best day ever. [[spoiler: Nikki finds her hanging from the rafters that same night]].
* KilledOffScreen: [[spoiler: She is hanged by Wakefield and her body is found hours later.]]
* LonersAreFreaks: Probably why she quickly hits it off with JD.
* NeverSuicide: [[spoiler: Her death is initially assumed to be a suicide, but it becomes clear that she was murdered]].
* NightmareFetishist: Possibly literally? After her mom was murdered by Wakefield she thrust herself into an ugly abusive relationship with Shane, and gave herself tattoos all over with messages begging for him to take her too.
* WeHardlyKnewYe: She received a lot of focus in the first two episodes,[[spoiler: but ultimately dies at the end of episode 2 and is basically forgotten immediately]].

The owner and manager of The Cannery, Harper's Island's local dive bar, and an old friend of Abby's.

----
* BadassBiker: The impression she gives off, although we never really see her in action.
* TheBartender.
* FlatCharacter: Despite being Abby's childhood friend, she never really has much relevance to the plot they way Jimmy or Shane do. She's got nothing to do with the wedding so she only ever shows up if the plot happens to bring someone to The Cannery.
* ImpaledWithExtremePrejudice: [[spoiler: How Wakefield kills her]].
* InformedAttribute: The advertising for the show called her 'The Biker Chick' of the group, but she doesn't seem to own a bike and never even mentions one. But "Waitress at a fishing pub" probably doesn't have the same ring to it.
* NowOrNeverKiss: When Sully and Cal are leaving to find the sailboat, Sully gives Nikki one of these. It is there first interaction and nothing comes of it since [[spoiler: Nikki is killed before Sully returns]].
* UnwittingInstigatorOfDoom: Her arrival at The Cannery in Episode 10 is this for [[spoiler: Maggie as it inspires her that the killer isn't after locals, leading to Maggie's abandonment of the group and imminent death]].

The manager of the Candlewick Inn, and Trish and Henry's wedding planner.

----
* BewareTheNiceOnes: Charlie calls her a 'pitbull' at one point, noting her determination and drive beneath her peppy exterior.
* {{Determinator}}: In her efforts to make sure the wedding goes along without a hitch, she can be overbearing and oblivious to others. It's unsure whether or not she means to come off as abrasive, but both Charlie and Henry find her overwhelming at different times.
* TheGenericGirl: One of several characters we never really learn much about.
* HiddenDepths: Though Maggie is shown to be a caring and considerate older woman, such as when she comforts Julia in the wake of the wedding rehearsal, and when she expresses relief that Madison has been rescued, she shows quite a more selfish side when it appears she can leave the group without being targeted. [[spoiler: She's wrong, and dies for it.]]
* HopeSpot: For Maggie, Nikki's arrival at The Cannery in Episode 10 was this, as it indicated to her that the killer wasn't interested in the locals. [[spoiler: In abandoning the group to this theory, however, Maggie turned out to be sorely mistaken]].
* KilledOffScreen: [[spoiler: After abandoning the group under the impression that she's safe, her hanged corpse is dropped from the roof minutes later]].
* NiceGirl: She's very friendly, though it is possible this a persona she puts on as part of her job.
* TooDumbToLive: [[spoiler: ''Really'', Maggie? Leaving the group based on a theory? It's no surprised when she is killed]].

!! Deputy Patrick Lillis
--> '''Played By:''' Nicholas Carella
----
* BackForTheDead: [[spoiler:Lillis vanishes from the series after J.D. is arrested and only reappears in episode 11, after being KilledOffscreen.]]
* CluelessDeputy: Lillis is slow-paced and unimaginative throughout the investigation and is well aware that Charlie only hired him as a deputy [[{{Nepotism}} due to being friends with his uncle.]] He does get a little more serious once the murders start being discovered, helping chase down [[spoiler:JD]] with dogs.

!! Dr. Ike Campbell
--> '''Played By:''' Jay Brazeau
----
* TheCoroner: Campbell examines the bodies of several murder victims and is quick to compare the situation to Wakefield's rampage seven years ago.

!! Cole Harkin
--> '''Played By:''' Dean Wray
----
* CrazySurvivalist: He has various pit traps and snares around the island and keeps an attack dog by his side.
* CreepyGood: Harkin is introduced in a way suggesting that he could be a slasher villain, but he's merely been trying to track down Wakefield (or his copycat) since the first killing spree.
* EveryScarHasAStory: His face was badly burned during Wakefield's rampage and is pretty off-putting several years later.
* IntergenerationalFriendship: Harkin fondly comments that J.D., who's a couple decades younger than he is, was one of the few people to visit him in the hospital, [[spoiler:and the two are allies in investigating the murders.]]
* UnwittingInstigatorOfDoom: In the BackStory, when he was still a young deputy, Cole was sent to rough up John Wakefield and run him out of town for stalking Sheriff Mills' wife. Wakefield was sent to prison for seventeen years when he non-fatally stabbed Cole in the ensuing fight and came out ready for a RoaringRampageOfRevenge.

!! Ben Wellington

----
* CruelAndUnusualDeath: He's tied up under a boat (while wearing an oxygen mask) right next to the propeller, and is left to helplessly await his impending death for some time before being shredded to pieces when the engine starts.
* InvisibleParents: Ben's parents (Thomas's brother and sister-in-law) are neither seen nor mentioned.
* WeHardlyKnewYe: Ben is the series' first murder victim and is onscreen for less than a minute, stuck in a death trap and unable to talk. He also appears in the first ''Harper's Globe'' tie-in webisode, inviting Robin and her boyfriend to drink with him in a Seattle bar the night before his murder, but that appearance is also only a minute or so long.

!! Deputy Garrett

* RedShirt: Garrett appears for several scenes in two episodes but has almost no dialogue or characterization, and [[spoiler:his murder while guarding the jail is fairly abrupt.]]

!!Julia Mitchell

!!Stacy [=DeKnight=]
-> '''Played By:''' Maria Avgeropolous

!!Karena Fox
--> '''Played By:''' Chilton Crane
A fortune teller hired as the entertainment at Trish's bachelorette party.
----
* TarotTroubles: Karena's tarot reading causes her to predict that Trish will be betrayed and that someone wants Abby dead. The intensity with which she makes those statements, even after the party, implies that she genuinely believes him, and both claims are accurate.

!! Brett and Lisa

A local couple who find Cal's lost engagement ring.
----
* RelationshipRevolvingDoor: Nikki says that they've been breaking up and getting back together for over a decade. When Brett finds a lost engagement ring on the beach, he finally uses it to propose.
* WhatHappenedToTheMouse: They're last seen getting into a fight after Chloe pretends to be Brett's mistress so Lisa will take off the engagement ring and she can snatch it back. It's never revealed if they realize they were duped and reconcile or what happens to them once the murders escalate.

!! Officers Darryl Riggens and Tyra Coulter

A pair of cops who are sent to the island with woefully out-of-date information about the recent killings.

* TheCavalry: They fly to the island to take custody of a murder suspect (not realizing he has already been exonerated and then murdered) and to evacuate the people who missed the last ferry. [[WeHardlyKnewYe They are ambushed and gunned down within a minute of arriving.]]
* OldCopYoungCop: Officers Riggens and Coulter provide a rare male-female example. Riggens isn't ''old'' (being somewhere in his mid-thirties to early forties), but he's noticeably older than his rookie partner. Riggens has a casual, SeenItAll attitude, while Coulter is bright, excitable, and eager about her impending first murder arrest.


!! John Wakefield: The Legend
-> '''Played by:''' Creator/CallumKeithRennie
A mysterious serial killer who appeared on Harper's Island in 2001 and, seemingly without motive, killed six people before being shot dead by Sheriff Mills, whose wife was one of the victims.

* DomesticAbuse: Implied to have been the case with [[spoiler: Sarah Mills, which was why she left him]].

* FreudianExcuseIsNoExcuse: [[spoiler: Yes, he was robbed of his son, and sent to prison for a long time after Charlie decided, ScrewTheRulesIMakeThem and beefed up the charge sheet after Wakefied's fight with his deputies]]. but this is mitigated by implications of his DomesticAbuse, his status as TheCorruptor, [[spoiler: his clear enjoyment for what he's doing]], and how, as Chloe points out in ''Splash'' [[spoiler: he's killed countless people who had absolutely nothing to do with what happened, many of whom weren't even from the island]].
* ImplacableMan: In true slasher killer fashion.
* NeverFoundTheBody: [[spoiler: Sheriff Mills shot him and saw him fall off of a cliff, but never found the body and instead took the credit for killing him by putting another corpse in his coffin. Sure enough, he survived]].
