* WritersCannotDoMath: Hazel incorrectly believes that the infinite set between zero and two is larger than the infinite set between zero and one. However, WordOfGod states that it was intentional, as he didn’t want his characters to always be right.
** A kind of [[MindScrew mind screwy]] subversion is that this is actually true, wrong, and backwards all the the same time. Two sets of infinity can be the same, just as easy as one can be bigger than the other. 0 to 1 could be the same, smaller, or BIGGER than 0 to 2. It really depends on what definition of infinity you use and who you ask.

* CaliforniaDoubling: Pittsburgh will play Indianapolis in the movie, due to Pennsylvania offering more generous film-production tax credits than Indiana.

* CompletelyDifferentTitle:
** The Norwegian title of the book is "Fuck fate." No, really.[[note]]HilariousInHindsight, since WebVideo/HonestTrailers' take on the film gives the film the alternate title ''Cancer F*cking Sucks''[[/note]].
** In Sweden the book is called "Förr eller senare exploderar jag", meaning "Sooner or later I'll explode".
** In German it's called "Das Schicksal ist ein mieser Verräter" meaning "Destiny is a mean traitor".

[[caption-width-right:290:"I can't tell you how thankful I am for our little infinity."]]
->''I fell in love the way you fall asleep: slowly, and then all at once.''

* FreestateAmsterdam: Mostly averted (Creator/JohnGreen ''really'' likes Amsterdam and goes whenever chance he gets), although the 16-year-old protagonists are served champagne in a restaurant quite openly.

* Egging: Hazel and Augustus help Isaac throw eggs at his ex-girlfriend's car. They're caught by her mum.

* MiseryPoker: Forms rather large (but unspoken) part of the Cancer Support Group experience. People with more serious cancers tend to get more respect automatically, and people with "lesser" forms of cancer (like appendicial cancer) are somewhat looked down upon.

* DidNotDoTheResearch: One of the very first paragraphs of the book has Hazel deride nurses, partially for having "a mere eighteen months of graduate education". A nurse has between two or four years of graduate education.

* MustNotDieAVirgin: [[spoiler:Gus says, "I'm gonna die a virgin," but then later in the story he and Hazel have sex for the first and last time, thus assuring that this never happens.]]

* GenreSavvy: The main characters know every terminal illness trope in the book.

* CastingGag: Creator/ShaileneWoodley and Ansel Elgort play a couple in this and siblings in ''Film/{{Divergent}}''. These two books/films also have a very large rivalry, alongside ''TheHungerGames''.

* MayflyDecemberRomance: Hazel, the sixteen-year-old protagonist, diagnosed with terminal cancer, has an uncertain number of years to left to live, but probably not many. Then she meets and falls in love with a seventeen-year-old Augustus, who is well into remission and will likely live a normal number of years. [[spoiler:However, Augustus' cancer recurrs, every reader's heart breaks, and Hazel is the one left behind by a lover's death]].

** However, [[spoiler:Augustus sending the pages of his ''Imperial Affliction'' sequel to Van Houten so he could make a eulogy for Hazel]] could very well qualify.

* DarkestHour: Once [[spoiler:Gus reveals to Hazel that his cancer has returned]], you have a saddening feeling that it's going to be a downward spiral from that point. [[spoiler:[[TearJerker And]] [[DownerEnding it]] [[DiabolusExMachina is]].]]
