I know, the lack of further meetings and interaction between Archie and James after that initial amazing significance is very frustrating! I love them, and am happy to imagine more and better things for them in AU fic, but it's definitely a weakness of the book (especially compared to Flight of the Heron...). And I also agree about the shippiness of Flemington/Callandar :D luzula has written an excellent Flemington/Callandar fic, if you're interested.
