in simpler terms, jekyll and lanyon swap narrative positions (?? is that the right term) with jasper and rachel respectively. (lanyons and rachels swap doesn’t technically work as well as Jekyll’s and jaspers does but shhhhh). Frankenstein becomes the mad scientist that attacks the society and moreau becomes jaspers idol.

longer explanation but WARNING!! it is 3am when i am typing this and i am terrible at explaining. it may be slightly incomprehensible.

so like jasper and rachel founded the society after jasper publishes his research and gets semi famous. two years before current events jasper is out on a research venture and gets bitten by a werewolf. he doesn’t want to scare rachel or the lodgers so he keeps it a secret (to his own detriment). flash forward to now and jasper gets a call to investigate a “creature” terrorizing the streets of london only to find hyde.

before jasper can process the dumpster man he is looking at hyde transforms back into jekyll. jekyll explains that while trying to prove his theory of spiritual alchemy at his university he may or may not have split his own soul. and got kicked out. and is now living on the streets.

jasper, not really knowing what else to do and kinda relating to the poor guy, takes him back to the society. he introduces his co-leader rachel, who pretty much keeps this entire thing up and running. (rachel and jekyll still become friends but she especially takes to hyde. that little brother shaped hole in her heart is still very much present!) then theres the lodgers (idk how they all swap) and then there’s lanyon, a university student at the society because it was mandatory for one of his courses. he is not enjoying it and would very much rather be breaking boy’s hearts back at school. lucky for him tho, there’s jekyll!

this goes about as well as you would expect. lanyon then spends the rest of his stay at the society trying to understand (and woo) the conundrum that is jekyll and hyde. it’s very fluffy and they learn to communicate like jasper and rachel in canon (yippee!)

unfortunately for jasper and rachel, they have been playing the “just friends” game for the last decade. im having a bit of trouble trying to flesh out swap rachel so i don’t really know if she’s in a lavender marriage like canon lanyon is or is estranged/divorced or just single but whatever the case is she likes jasper but thinks he just sees her as a friend while jasper is madly in love with her and is too scared to tell her. this problem has only worsened since jasper got bitten. everyone else tho is aware of how they feel about each other and are stuck witnessing their tortuously long slow burn.

(hyde and lanyon at some point probably come up with a scheme to try and get them to confess. it goes horribly wrong.)

so yeah. this au has been floating around in my head ever since i read the comic for the first time. it mainly came to be because of how well jasper and jekyll parallel each other and because i wanted to draw stupid fluff and older jasper lol.
