remus is a living link between the first and second wars (which is hard to find considering how many people died in the first war), and yet his role in the first war is rarely spoken of even though that could illuminate important backstory. he is a werewolf and therefore represents an aspect of wizarding society that is rarely shown in the series, and yet he is presented as being somehow unique among werewolves (the rest of which are generally all depicted as monsters). he is financially destitute and spends a great deal of time living on the streets and/or in muggle society, which means that he could provide an alternative insight into wizard and muggle relations and into social inequality in the wizarding world, and yet the topics never come up when remus is around.
remus knew lily and james well and still grieves for them as much as sirius does, and yet his relationship with them is never mentioned, and harry—even after finding out that remus knew his father and mother—never once asks remus about them despite the fact that he is otherwise desperate for information about his parents. remus manages to come out of the first war and more than a decade of grief and isolation not only alive and functional but also as a figure of great strength, calm, and deeply held moral beliefs, and yet his guidance is never offered or asked for, he is never seen taking care of sirius even though that role should logically fall to him (no one takes care of sirius, actually, except harry, who is the one who should be the least responsible for sirius), and remus’ only role in the order is to liase with other dark creatures, because that’s the only value that dumbledore—and jkr—sees in him.
so i think it’s quite easy for me to say that jkr dropped the fuckin ball with remus lupin and that i’m never going to be over it
