I love the silly callbacks and foreshadowing. I'm sure it's been said somewhere in this nearly 18k page thread, but Avery saying some random comments at a party in Ch. 9 to what she believed was her friend is random and could easily have been passed over by DPC. It could have been left on the cutting room floor, as it were, as it could easily have never had anything to do with our MC... but he had plans for those words. Very Chekhov of him.
Yeah... I see you, DPC.
It took me running it back on a different path to realize the importance of those words in Ch. 11. If I'd been playing every path to version update as new versions were coming out, I probably would have forgotten entirely as the two lines mean nothing out of context. It almost feels like I'm going to have to go back and replay all the paths again when the story finally wraps up just to see what details I missed like this across the board... and of course, I love it.
