These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Author's Saving Throw: The first Boney Island challenge has a downplayed example. Chris was supposed to warn the contestants during the challenge briefing (as per canon) that a curse would befall anyone who took anything from the First Nations burial ground located there. For whatever reason, the author forgot to include that bit, and didn't discover the oversight until well after posting the chapter. Rather than go back and quietly revise the scene, the author wrote a scene for the following chapter wherein one contestant who happens to know the legend warns another contestant who has innocently picked up an artifact from the area. This approach had the advantage of giving the resident motor mouth another monologue.
Sadie quickly became an audience favorite, and appears to be the story's most popular character who wasn't a major character in the canonical first season.
The sheer amount of the He's Just Hiding reaction pertaining to a certain challenge victim makes it wholly apparent how much the reader base enjoyed their brief presence.
He's Just Hiding: This was a widespread reader reaction to a certain contestant being apparently killed in a challenge accident. Not surprising, considering that there was no visible blood and the victim's body was not recovered.
Pandering to the Base: The author has acknowledged that Sadie has gotten several additional scenes because reader response to her portrayal was so overwhelmingly positive, and that the Lindsay/Justin ("Lustin") pairing has also gotten some additional play due to favorable reader response.
