everyone is entitled to their own little regency au that lives in their heart and in mine jon gets yeeted back into the 18teens but jonah also inexplicably has all his memories from the next 200 years (i had a wonderful dream!) and is so sure this time he can get the apocalypse done in 50 years max (efficiencymaxing) if he can just sweet talk his archivist (who came back to him 🥰) into being cool about it (because you can only really pull off the ‘trick’ route once) meanwhile jon is running around edinburgh trying to looney tunes drop a piano on him. ideally this also involves at least two full chapters of both of them mutually pretending to have amnesia in an attempt to get the drop on each other
