This story is a Death Fic, so you may encounter unmarked spoilers. You have been warned.
Legacy provides examples of the following tropes:
Absence Makes the Heart Go Yonder: Ten years after the show, most of the couples are no longer together because they had come from all over Canada, so most lived too far apart to see each other regularly.
All There in the Manual: The story page includes hyperlinks to supplemental information on ancillary topics, including the song that became the basis of Trent's tribute song.
Anti-Climax: The show's producers scrap the final episode's scheduled jury vote in an attempt to avert a major anti-climax, as they can see that one finalist has only token support at best. A winner-take-all final challenge is substituted.
Armor-Piercing Question: When Courtney rants about her unfair elimination and thoughtlessly says that she should have been kept on instead of the recently murdered Gwen, Noah shuts her up by saying, "She would be here. Alive. And you?"
As You Know: Heather does this when she points out that the Muskoka District is a major summer colony, that being how she happened to be near enough to the camp to drop by on a whim.
Author Catch Phrase: Beginning narrative sentences with "So it was", usually in the form, "So it was that X"
Bad Dreams: Most of the surviving contestants must deal with nightmares in the wake of their campmate's death.
Bittersweet Ending: Heather's climactic gesture of remembrance gives the dénouement this quality.
Blue and Orange Morality: The insane Izzy doesn't grieve for her dead campmate because her diseased mind isn’t capable of grief or sadness.
But We Used a Condom: Lindsay had an unexpected pregnancy with a longtime boyfriend, despite presumably using some form of contraception on a regular basis.
Cell Phones Are Useless: There is a reference to cell phone coverage in the vicinity of the camp being "spotty". This is presumably why the show's staff used two-way radios.
Chekhov's Gun: Heather's pregnancy is mentioned thrice in the first chapter, but doesn't become important until near the end.
Creator Thumbprint: All of the author’s stories, except for short vignettes, include at least one reference to a Gilbert and Sullivan operetta. The author's pen name is also a G&S reference.
Dark Fic: The story is based on violent death, from comedic source material.
Dead Guy Junior: Heather’s baby is to be named after her mother's late campmate.
Death by Genre Savviness: A certain contestant, who happens to be a slasher flick buff, is convinced that the serial killer is just an actor hired for the challenge, so she doesn't try to defend herself. Tragedy ensues as the story diverges from the canon moments later.
Death Fic: The story is all about the repercussions of a contestant's death. Said repercussions are still being felt a decade later.
Dénouement: The last chapter is entirely dénouement, with the climax coming at the end of the preceding chapter as Heather reveals her gesture of remembrance.
Her short, raven-black hair was styled in a businesswoman’s cut. Her belly was distended to accommodate her daughter-to-be; her breasts were engorged in preparation for their purpose; and her skin, beneath a hint of sunburn and a generous dose of skillfully applied makeup, was suffused in the characteristic glow of advanced pregnancy. All in all, while still a beautiful woman, she bore little resemblance to the teenaged “dragon lady” she had once been.
Do Not Taunt Cthulhu: When Chef Hatchet leaves Duncan and LeShawna to guard the (currently unarmed and docile) serial killer, he sternly warns them to not taunt the prisoner.
Dragon Lady: Invoked for Heather, who is described as having once been a "teenaged 'dragon lady'". This is a reference to both the ethnicity and personality of her canon counterpart. Indeed, the author describes Heather thusly, with minor variants, in every one of his stories in which she appears.
In the first chapter, Heather’s voice trails off into a dramatic pause.
In the second chapter, Heather’s thoughts trail off when she gets too close to something she really doesn’t want to think about. The reader is given enough information to figure out just what that something is, and is unlikely to blame her.
One of the seats at the elimination ceremony venue is draped in the dead girl's nightgown and is not used for the rest of the competition.
When the previously eliminated contestants return for the final challenge, two of the surviving contestants keep an empty space between them when they approach the bleachers and when they take their seats.
Framing Device: Heather and Duncan at Camp Wawanakwa comprise the frame story, and their reminiscences comprise the inner story.
Grief Song: Trent writes a song in tribute to his late girlfriend and first love. In the following years, he sings it at most of his gigs, usually as the closing number.
Heel Realization: Heather reached out to Lindsay after the latter lost her baby, but Lindsay did not acknowledge the gesture. Lindsay did respond to condolences from Courtney, among others, so Heather assumed that old resentments still lingered. The incident left Heather questioning, for the first time, the wisdom of her game strategy.
Her Heart Will Go On: Gender flipped with the bereaved Trent. He started out in deep mourning after the death of his first love and continues to make annual gestures of remembrance, but he otherwise went on to live a normal life.
Heroic BSOD: When the other contestants see one of their own violently struck down, they just stand there and seem to have no idea of what to do.
Holy Backlight: When Heather comes out of the kitchen and sees Duncan standing in the doorway to the lodge, she can't make out much detail at first because he is backlit. When he comes into the lodge and is no longer backlit, she recognizes him.
In Medias Res: The opening chapter is set years later than most of the next two chapters.
Irony: Heather is planning to name her baby after her late colleague, whom she couldn't stand when the latter was alive. Heather appreciates the irony of her decision, and comments on it.
Lampshade Hanging: Heather comments on the seeming absurdity of her decision to name her baby after a former enemy.
Nested Story: In addition to the nesting inherent in using a frame story, the main story contains Heather's story of how she came to choose her expected daughter's name.
Never Found the Body: Izzy was reported to have been killed in the sinking of a ferryboat, but her body was never recovered. This is part of the reason why neither Duncan nor Courtney believes that she is really dead.
No OSHA Compliance: Played with and ultimately defied. It takes a contestant's death and the enactment of a "memorial" law to clearly establish that reality show contestants are to be considered employees for the purpose of applying workplace safety regulations.
Obvious Pregnancy: Heather is almost eight months pregnant. This causes her some trouble in getting out from behind the steering wheel of her car.
One Drink Will Kill the Baby: When Duncan offers to share his lunch with Heather, she has to find her own beverage because all Duncan has is beer. For the sake of her 8-month fetus, Heather is unwilling to drink anything alcoholic.
Paper Cutting: Subverted in that the chainsaw psycho tries to do this, but is interrupted at precisely the wrong moment and so inflicts a serious wound instead, more or less by accident.
Signature Style: Description-rich and dialogue-light, with a flavor that readers have described as “19th Century”, “elegant”, “nearly poetic”, and so on. The author is also inclined to explain things in detail, whether in the story or in notes, and to use "death and renewal" themes.
Slice of Life: The story begins and ends this way, hence the lengthy discourse on the riveting subject of what Heather and Duncan had for lunch.
Wham Line: Two near the end of the first chapter which firmly establish the tone of the fanfic (after it was hinted at previously):
Heather: How long has it been? Ten years?
Duncan: Ten years ago today, may she rest in peace.
Heather: That wasn’t really what I meant, but... But, yeah. Poor Gwen.
What If?: The climactic encounter with the chainsaw psycho (Episode #19, "Hook, Line and Screamer") turns out differently than the canon version. That single change drives the entire story, with consequences that are still felt a decade later.
"Where Are They Now?" Epilogue: While not actually an epilogue, the reminiscence portion of the story ends with thumbnail sketches of what everyone is currently up to.
Worthy Opponent: After ten years, Heather is ready to admit that a certain despised campmate was a valuable teammate before the merge and a formidable opponent after.
