* AlternateCharacterInterpretation: In-story and out.
** The message of the story is how we look at people as mirrors rather than windows.
** Q could be read as a romantic adventurer or an obsessed tragic figure. Q even claims that Captain Ahab is the hero of Moby Dick. (That said, he outright admits he never actually ''read'' the book and just wanted to get his final paper done, so he probably went off the website summary and wrote from there; a time-honored tradition among people who leave things until the last minute.)
* CrossesTheLineTwice:
** At the prom afterparty, Ben sets a county record for longest keg-stand. Radar describes him as some kind of "autistic savant".
** During the road trip, [[spoiler:Radar is bought a T-shirt with a Confederate flag on it that reads "Heritage not Hate". Radar is black.]]
* CrowningMomentOfFunny:
** "IT'S NOT MY FAULT THAT MY PARENTS OWN THE WORLD'S LARGEST COLLECTION OF BLACK SANTAS!"
** The road trip, especially Radar's shirt. For context, [[spoiler:Radar is bought a T-shirt with a Confederate flag on it that reads "Heritage not Hate". Radar is black.]]
** The Beer sword.
* {{Deconstruction}}: Of John Green's own ''LookingForAlaska''.
* FamilyUnfriendlyAesop: So humans will never truly understand each other.
** Actually, the {{Aesop}} is more along the lines of people ''needing to learn'' to think of others complexly, '''not''' that we ''can't'' understand each other.
** It could even be argued that realizing that you can never understand anyone completely isn't that unfriendly an aesop, given that it allows you to begin to think of people complexly.
* WhatCouldHaveBeen: In the first draft, Q and the crew finally catches up to Margo in ''Kashmir'' (yes, that war-torn region in Asia), whereupon Margo dies in a freak earthquake. Considered he did the same thing for the ending of Literature/TheFaultInOurStars, Going completely off the chain in the first draft may be simply part of the regular writing process for Creator/JohnGreen.
