The more I think about it, the more I am interested in what happens before and after canon. It's your fault I caught the AS/S bug, but they genuinely excite me as story possibilities, because you can do anything with them and their world, so long as it's plausible. At the same time, I am really interested in the James Snr era, especially Remus Lupin. How does he fit with them? Obviously he's shagging Sirius, but how did that start?
