Oh, and while I'm away, here's something to read:
A great discussion at musesfool's journal: http://www.livejournal.com/users/musesfool/391203.html?view=2649379#t2649379, about Sirius and Remus. Many of the points made there fit rather well with what I'm *trying* to convey with my own S/R fic, which can be found here: http://www.allabouthmpf.com/together.htm. (German version forthcoming; already being beta'd.)
