There are many great observations here!
Doylistically, I wanted to conjure up the fannish experience of having theories about hints in storiesโฆ thus it had to be a book with layers and secrecy. Alice and Rae and Eric all have different thoughts and know different things about the books, and by exchanging those thoughts they come closer to the truth. But no reader reads quite the same story as any other, and thatโs literalised as we see all three of them reading three different (changed) stories.
For example, the common experience of thinking thereโs chemistry between characters and fearing thatโs all it will ever be due to it being a queer pairing. I thought it would be nice to validate that feeling, even for stories where that IS all it would ever be (sorry to the most recently hurt by Stranger Things!) and tell them they werenโt wrong to see it. But for those in book, itโs the also-common and sometimes terrifying experience of โyou and your friend, could there be something there?โ
Books sometimes just do have real world shoutouts in them. The Time of Iron series was partly inspired by A Song of Ice and Fire and its fandom. The series has a reputation for being grimdark I donโt think it entirely deserves and it does do whimsy. Currently I am watching House of the Dragon, rolling around in glee and torment because I have read the faux-history itโs based on, and I know one of the characters - Oscar Tully by name - has relatives called ELMO AND KERMIT TULLY. Soโฆ the horse named Google Maps could be canon. You donโt know.
I know, of course, but thatโs different.
I was also thinking about adaptation, for whatโs an adaptation but a changed story? In A Song of Ice and Fire, the characters Renly and Loras are implied to be gay. In the TV adaptation Game of Thrones, theyโre explicitly so. But also the ASOIAF books are not finished and the GOT show is, so there are many reveals made in the show that arenโt in the books yetโand may never be. One character gets resurrected in the book who isnโt resurrected in the show. Another character is resurrected in the show, but as of his latest appearance in the books, heโs dead in the snow. Heโs been lying dead in the snow for 15 years. So who is doomed, and by which narrative?
In the Grandmaster of Demonic Cultivation book, during the climactic moment the hero Wei Wuxian proclaims (very explicitly) gay love to his love interest. In the Untamed TV adaptation (because of government rules and not creator decisions) during the climatic moment the main characters have very little to do except stare at the absolute mastermind vs mastermind shenanigans unfolding before them. In the Vampire Chronicles books, vampires canโt have sex so their sexuality remains fairly ambiguous for at least a while. In the AMC show we have gay vampire sex in the pilot.
And then, thereโs narrative tricks. All stories use them. The Murder of Roger Ackroyd hides who the murderer is when theyโre in very plain sight. In A Song of Ice and Fire, Ned should be thinking of a very treasonous secret he has constantly while in the presence of the king. But they get elided to serve the story better. So indeedโฆ what is the purpose of this story, who is it by, who is it forโฆ and what is its effect meant to beโฆ
Are excellent questions. There are clues. Like Eric seeing Liaโs manipulations by close reading when Rae dismissed her, like OP, you can find them. I put them there for readers who like to treasure hunt, because Iโm a reader who likes to treasure hunt too.
